Mac Mini :: Does Not Boot, No Video Signal, No Chime
Feb 2, 2012
My mini "starts" without chime when I press the power button on the back. The fan starts, the light in front goes on and I hear some clicks which could be the hard drive. The screen remains black (no signal) and the mini does not respond to the USB keyboard power button. It does not start when pressing it and will not power down if I press it for any length of time when it is on. Pressing the power button on the back for some time shuts it down.Â
I have an '07 vintage (DVI) Mac Mini I use as a media center. I haven't used it in a few months & its been shut down during that time. I went to start it up today & the power light went on & I could hear the fan start up but no start-up chime & no video.
I did an PMU reset to no avail. I'm thinking the logic board is done (it's under warranty & I have an appt. with a "genius" tomorrow). Just wondering if there is anything else I should try before I bring it in.
I received my new mac mini last week and installed a few things on it over the weekend so that I can run it as an HTPC. Works great but I am having one issue and that is with the video signal. I have the mac mini connected to my Samsung 720p LCD TV with VGA using Apple's miniport to vga adaptor.
When the TV is already turned on and I start the mini or bring the mini out of sleep then everything works OK. However if the TV is off and I start the mini or bring it out of sleep and then turn on the TV, I get a "no video signal" message.
I recently reinstalled a clean Tiger on my old MDD G4 with the intent on giving it to a friend of mine in Oregon. Everything was smooth here in Los Angeles. Got the OS on and running sweet... 10.4.11 combo update... all's well.
I drive up to Oregon, set it up in his office using his old CRT monitor and power it on. It chimes and manages to find the Tech Tool eDrive recovery partition, but not the OS on the boot drive. Then, seconds later, screen of death/kernel panic and no boots or startup chimes thereafter.
Steps I've taken: I have reset the PMU I have removed all peripherals, including viddy, SATA adapter and all but on stick of RAM Tried every stick of RAM by itself No startup chime -- just a fan for a few seconds then a super fan kicks in... no signal to monitor at all.
Strange symptom: at times power was making it to the drives, and other times not. (determined by me putting my hand on the drive to feel its vibration or lack thereof during boot).
Do I need a new PSU? And if so where to buy?

I have a lovely secondhand 12 inch Powerbook G4. It won't boot but will just chime and go to a grey screen. I can't boot to safe mode but I can get into Open Firmware I have reset PRAM and the power manager. I don't have the install CD but I borrowed one from a friend with the same model and it wouldn't boot from that.
Ive got a G4 Power Mac 2x500MHz that Im getting a bit frustrated with.
Situation: - Power supply seems to work as power flows once I hit the power button. Fans spin, red light comes on the board, connected drives spin up, drawers open. - No chime. At first it was sporadic, but now non-existent. - No video output. Has the original AGP ATI 128 Rage Pro graphics card. - No power to USB ports? Try plugging in devices that light up in USB but nothing happens.
What Ive tried: - Ive replaced the board with a known good board and get the same results, and of course i thought this was the main problem. I did get a tiny whiff of burning smell from the previous board, though no signs of physical defect on it. No smell from the new board. - Replaced and swapped around about 6 different ram sticks. - Tried PCI graphics card (probably not compatible though) and no results, as expected. - Reset PMU of course. - Swapped processors.
Late last night, I ran into some problems with my iBook G3. It's the 700 Mhz model, with 384MB of RAM. Nothing else special in terms of hardware config (unless an Airport card is special). OS X 10.2.8.
Basically, the computer seemed to hang and I did a hard reboot, and upon starting up I got a folder with a flashing ? .
I can't seem to find my Install disc 1 to run Disk Utility or just boot up - hopefully I will find that when I go home tonight (or maybe I left it at my parent's place), but I checked using the Hardware Test CD and it didn't detect any problems.
I am having problems opening the CD drive, so I've had to open it using a paperclip. Sometimes it doesn't appear to be using the CD.
I also have run the Micromat test CD that came with Applecare (of course this machine is almost 4 years old so that's finished...) and it detected a problem with the Read Buffer last night, but then I guess the battery ran out while it was on the last test.
This morning, I ran the Read Buffer, Write Buffer, and Volume structure tests and the first two passed very fast (unlike last night), but the Volume Structure test failed. I'm not surprised since I've been aware I have issues with this before. I tried to repair before going to work but at one point it seemed to hang so I gave it another hard reboot.
Last night, I would sometimes get the apple logo with the spinning "clock", and sometimes I would get the ? but it would never get to the login screen.
I have a mid-07 Santa Rosa MBP. When I turn it on, nothing comes on the screen (not even backlight), but I'll hear the startup chime and 2 seconds later, it reboots and does the same thing. Here is what I have tried:
1. Reset SMU 2. Reset PRAM 3. Replacing HD 4. Replacing PRAM/CMOS battery 5. Tried booting off DVD (but it reboots too fast after the chime)
I have a 400 mhz Titanium powerbook I'm trying to resurrect for my teen daughter. Just replaced the internal pram battery, the external regular battery, and the a/c cord, all with brand new parts. The book was dead, and now I have power but not much more.
When pressing the power button I get one chime, and then I can hear the fan working, but no hard drive sounds. The screen is black.
Eventually, when left sitting, the thing will turn itself off. It seems as if it is not booting completely, but then I can't see anything. I am used to hearing hard drive pops and whirrs though, and nothing here.
1. I tried resetting the PMU with the button on the back of the unit. 2. I tried resetting the pram with cmd/opt/p/r before power, but no matter how long I hold I only ever get one chime. 3. Tried booting with my OS Tiger retail CD (which is what is installed) and the drive barely spins, and the screen remains black. Holding C doesn't help. 4. The new battery is charging normally. 5. I tried removing the two ram sticks, moving them around from slot to slot, and using one ram or the other. Nada. 6. Tried forcing shutdown by holding power button 10 secs, then rebooting. In fact, that's how I have to shut it down when I need to, since I can't see anything.
This laptop has been in storage for about a year. This is the same problem I had when I put it away. I think perhaps the laptop might have been knocked off the coffee table and fell about 2 feet to the floor a short time before these problems. I heard it, but the kids won't admit it. *grin* It worked fine for about a week or so, then began losing video at startup.
I just spent about $75 in parts. Should I maybe try a new PMU board before chucking the thing? Any other ideas what might be happening?
I've read till my eyes are blue, and can't seem to find a boot issue with one chime on this machine.
I am having a problem getting my G5 to boot. Half the time when I turn it on I get no chime. The other half, I get the chime but the boot process does not continue. If I leave the computer on the fans begin to progressively get faster and louder after about 5 minutes. I've tried starting with various USB and Firewire components unplugged and have even gone to just a keyboard and mouse. No change. Can I get the computer to boot from an OSX CD? How do I open the tray? etc.

Although this isn't a very important problem, I have noticed on my early 2K8 Mac Pro the Boot POST chime will not play through external speakers. Is there a way to enable this, as it is awfully tinny from the internal speaker.
So I was just there, using my computer, doing nothing out-of-the-ordinary. I decided to open up a program (Yahoo! Instant Messenger, I think it was) and the computer went nuts. I completely froze...nothing I tried worked. So I shut the computer down and tried rebooting it. It chimed and went to the white start-up screen with the apple...I let it sit for about ten minutes to let it restart. Still the white screen. I shut it down and tried it again. Same thing.
Is my computer dead? What might I be able to do to fix it? How much might it cost?
I acquired an iMac G4 PowerPC with a 20" flat panel. System powers up but does not boot displays Apple logo screen and busy indicator. I have tried various commands safe-boot and it does not seem to work screen never changes. No Apple chime on start-up.

I just recieved my Mini DP to DVI adapter so that I can use my second 23" Apple display. I just upgraded to ATI Radeon HD 5770 so now I have 1 DVI and 2 mini DP. I want to run 1 display off of the DVI and 1 off of the Mini DP. Both displays work with the DVI port but neither of them work on the Mini DP with the adapter.
I know that I need to upgrade to Snow Leopard for the ATI Radeon HD 5770 to fully function. I am waiting for the upgrade to arrive in the mail. Do I need to be running Snow Leopard for the Mini DisplayPorts to work at all or is there something I can fix before the upgrade?
I have a 2009 model of Mac Mini and I have a 32" Samsung TV as the primary display hooked up though MiniDVI converted to VGA and it works properly. But my second Sony 19" monitor hooked up though DisplayPort Converted to VGA does not receive signal. It is detected by Display but no signal is being sent to it. When I have only the monitor though the DisplayPort hooked up it doesn't receive signal but when I have one only though the MiniDVI it displays fine so I know its not the Monitors.
I have a Mac Mini, and recently I buy a television by Sony 3d (46"). For my surprise, the television don't accept the signal from Mac Mini. On the screen appears the message (Signal Incompatible). I change all configurations, but nothing. I call to Sony and they don't have idea about the problem.
I have MacMini and the display signal turns off intermittently (i.e. not just sleeping).Â
The display is via a VGA connection to a Philips monitor (although I've tried with an Acer VGA monitor too and get the same problem).Â
The only way to fix it seems to be to turn the Mac off and on again.Â
I feel pretty disappointed. I've used Apple Macs since having a Mac Plus 20 years ago and have always recommended people to use them because "you just plug things in and they work"...Â
But this is simply rubbish. It's practically useless. should I just try to get my money back under the "not fit for purpose" clause in the sale of goods act.
What a great place! I'm wondering if anyone has a solution to connecting a mini to the above TV.
I have the same TV in 32 inches and use a mini to HDMI cable that works perfectly. For some reason, the 40 inch TV says 'no signal' when I try to hook it up the same way. I've tried all the HDMI ports...including ones that work with other devices.
I just got a Mac Mini no too long ago and while moving to my new apartment, my wireless router had a tragic accident and is no longer with me. So I thought "hey, I will just use my Mac Mini to broadcast a wifi signal so my other devices can connect to it." So I spent the morning setting up the internet sharing in the Mac Mini system preferences. Got my Dell Studio 1555 to connect with no issues. But my roommates acer notebook won't pick up the wifi signal at all. Checked it on both of our smart phones (both are android models), my nook, and even my ipod touch. It is only showing up on the dell for some reason. I was wondering if anyone else has encoutered this issue before Mac mini is currently set up with 128bit wep with a 13 character password.
I have a March 2009 Mac Mini that was working fine under Leopard when sending out a signal from mini display port to hdmi and then to a Samsung HDTV. Now when I upgraded I get more options for monitoring HD signals but my TV signal drops out intermittently. I suspect this is a bug with Snow Leopard and HDMI. Anyone have any inklings on how to solve this issue?
Just a warning, I bought a Mac Mini (2009) and wanted it to hook it up to my TV. My TV does not have HDMI or DVI inputs so I bought a Mini DVI to Video adapter from Apple.But I could not get it to work, then I googled for it and it seems this adapter does not work with 2009 Mac's since it does not output an analog signal anymore!

So anyone that wants to hook up his new Mac to an older TV set with the Video adapter, you are warned.I guess i'll have to buy a Mini-DVI to VGA adapter and then a VGA to SVIDEO converter..
When I plug my Intel iMac into our old Sony Trinitron via the S-Video input no connection can be made. Is this a problem with leopard not recognizing my TV or possibly something else?
Just bought the new mac mini with HDMI out - 2.66Ghz, 8 Gb RAM, 500 Gb HDD
A lot of mkv or avi files I playback appear pretty choppy in VLC - my primary app for watching movies and tv shows.
I have a Drobo with two 2 TB SATA drives where I store all my stuff and which is connected to my mini via firewire 800.
I've tried playing the same video back from both the Drobo and from the internal hard drive, to see if the choppiness was on account of the external drive or not. No difference really. A choppy video remains choppy from either place.
It's pretty strange because some 1080p videos play just fine, with no choppiness whatsoever, while other 720p videos or even standard definition divx files are still choppy.
I have an acer 20" lcd and it has dvi-d, is that causing issues with the mac mini or is the logic board probably bad? it works on every other unit i plug it to.
Odd problem that just started with my 2008-ish iMac. Probably not related, but iTunes did it's typical thing of hard freezing my entire system. I hard rebooted my iMac, and it rebooted with no video. It chimed, but the screen remained black. I searched for the problem and found an old Apple article that suggested resetting the PRAM. Not really believing it would work, I tried it anyway and, still no video.
I let it boot for what I believed was a reasonable amount of time to get to the log in screen. Then I hit the F-buttons for volume and received the chirp letting me know that I was changing the volume. I hit the F-buttons for brightness, but did not get anything from the screen. I was working, so I shut it down again, let it sit, and started it up later. Video! It started up just fine. I know it probably needs to go to the Apple Store, but I am not going to be able to get down there for a day or two.
Info:iMac (24-inch Early 2008), Mac OS X (10.7.4) Reboot...no video.
Im thinking of completing the mac transformation from work and laptop to my home computer, does anyone know, does the mac mini have a good enough graphics card to play HD video thats downloaded, my current PC's graphics card struggles.
I knowits due for revision so going to wait for that. Say the new mini has the same GPU as the current mac book, will that be enough?
I am using both video outputs on the back of the mini, VGA and HDMI. Thes VGA is running to a projector and the HDMI is running to a computer monitor. I am also running Bootcamp WINDOWS 7. When I power up the Mac, the computer monitor goes to sleep and defaults to the projector as the main monitor. If I power on the projector first, before powering the computer on and then power the MAC on, it recongnizes the computer monitor as the default monitor. Why can't the MAC mini recognize the computer monitor(HDMI) as the default when both video outputs are connected?

I have an older intel Mini running Lion. This morning my son told me it was displaying the screen that says you need to reboot.I told him to reboot it and let me know how it went. He came back and said it just brings up the reboot screen again.I rebooted it again, and again got the reboot message screen.I didn't start writing down the error messages because I assumed I would be able to get it fixed eventually.I rebooted with the option key pressed and selected the recovery disk. Again, I got the reboot screen.I then used my wife's macbook to create a USB recovery disk, booted the mini again, and selected the USB disk.I got the gray screen with the apple and the spinning symbol....it stayed on that screen for over half an hour.At that point, I noted that the indicator light on the USB drive was showing no activity, so I shut the mini down and tried again to boot from the USB drive.This time I got the reboot screen again.At this point I wrote down the following error message: [code] At this point I wondered if I had corrupted something on the USB recovery disk by stopping it earlier.I rebooted with the option key pressed and selected the recovery partition on the HD, hoping to see if it provided the same error message.I got the gray screen with the spinning logo and it just hung there. After 20 minutes, I rebooted and just let it follow its normal boot procedure. Again, I got the gray screen with the spinning logo and it's been sitting there for the last half hour.
