27" Monitor flickering then losing power

Hello,
At the office we have a 4 year old 27" apple monitor. For the last two weeks it's been flickering occasionally and on a couple of times lost power altogether. Now it only holds power for a few seconds.
If I unplug the power and leave it for a few seconds/minutes then put the power back in the back comes on for a few seconds to a minute, flickers and then turns off.
We've test the cables with another monitor which we bought at the same time and they work fine.
It leads me to believe that capacitors on the board of the monitor have failed. As the warranty has expired are there any exceptions in this case or do I need to go buy a new set of caps and soldering iron?
Appreciate any feedback.

My problem is that unplugging the monitor does not help.
By changing the resolution a few times I can fix the screen flicker problem but then get a single verticle line of horizontal lines on the right side of my monitor that increase in speed as time goes by.
It is the lesser of two evils so I just use 5/6 of my monitor and cannot see the lines against a black background.

Monitor flickering requires power unplug/replug

I'm using an HP w2558hc monitor on a T60 running Windows XP Professional with an ATI Mobility Radeon X1400 display adapter. Everytime I reboot the laptop there's a rapid left/right jiggling of the display, which is noticeable enough but more so when you look toward the edges of the screen. By trial and error I found if I unplug the monitor from the wall power outlet, wait 10 seconds and plug it back in the problem goes away until the next reboot.
HP tells me it must be the laptop's display adapter because they had me plug the monitor into an old Dell 2100 tower I had hanging around (Windows 2000 on an Intel 810 graphics card) and it did not exhibit the problem (albeit that 10 yo PC only went to 1600 x 1200). Also because the flickering doesn't start until the Win logon prompt appears, which is when they say the graphics adapter kicks in. And theres no flicker if I turn the monitor on without connecting it to the laptop to display the "No Video Input" message.
I have tried the following remedies without success.
- Updated the T60 graphics driver to the most recent one Windows Update could find (version 8.362.0.0, 4/5/2007)
- Uninstalled the HP driver and went plug and play
I posted this if case anyone has a similar problem, at least I found a workaround. The unplug option is only slightly annoying, although if the adapter is truly at fault I can't see why unplugging the power cord stops the shaking. (Simpy cycling the monitor off and on with the power switch won't fix it. I power off, then unplug.)
If anyone has any other ideas I might try I'd be glad to hear them. Lenovo hardware support suggested I try installing the Presentation Director, has anyone fixed any similar problems that way?

HP 2010i monitor- Flickering after coming out of hibernation

When I turn the monitor on, or wake the monitor back up after it has gone to sleep, the screen flickers for a minute or so, gradually lessens, then stops flickering. It appears to be the backlight leds flickering around the perimeter of the screen (my guess). It is connected by DVI cable to my tower, the connection seems fine. Monitor is about 3 years old and is out of warranty. Is this something that can be fixed (worth repairing?), or is it just dying a slow death and I need to shop for a new one?

Hello @tgantt,
I understand that you get flickering after waking from sleep mode on your computer. I am providing you with some steps you can try below:
Step 1. Unplug the power cord from the back of the monitor and the wall
Step 2. Hold the power button down for at least one minute
Step 3. Plug the power cord back into the monitor and then into the wall outlet (not a power bar or surge protector)
Step 4. Press the Menu button on the monitor
Step 5. Navigate to the Factory Reset option and select it
Step 6. Replace the cable connecting the monitor to your computer
If the above steps did not resolve your issue you can try installing the HP 2010i 20-inch Diagonal LCD Monitor Drivers on your computer. If the issue still persists I recommend that you download and install the latest graphic drivers for your computer.

Envy IPS 27 Monitor - Flickering

Graetful for any advice.
Monitor now started flickering.
Manifests as a black screen that flashes on/off each second with faint short coloured lines (based on the picture on the desk top) around the edge of the screen.
No changes to system/wires/location etc.
Expensive monitor and just out of warranty so hoping that this is fixable.
Many thanks,
AdamS22

HP LA2205wg monitor flickering

When I turn on the monitor, it immediately starts to flicker like it needs degaussing. I thought it was the computer driver, so I disconnected it from the computer and tried it again. It flickers with no input from computer. It was given to me so I have no idea of its history.

Monitor flickers with green tint

Monitor is about 3 years old. Often times, the screen takes on a blue-green tint. Sometimes just flashes on, then back to normal a few times. Sometimes tint stays for a minute or two. All images are visable, but everything has a strange greenish cast to it.

Please help. My facebook app will not open on my iphone 4. I deleted it,numerous times and downloaded it again. It uploads, but when you click on the icon, it flickers then closes. Help.

Help.

Then the next step would be to restore your phone. My advice is that prior to restoring you import your photos and videos to your computer and back up your contacts (by syncing them with iCloud or to a supported program on your computer using iTunes) as a number of users report losing these when restoring their device.

Mirroring LG Monitor stuck in Analog Power Saving Mode

I have a macbook from 2006, and just attained an LG L1900J LCD monitor. When I connect the monitor to my macbook using a DVI to VGA Cable attached to a Mac mini DVI to VGA adapter I get no picture on the monitor and the message "Analog Power Saving Mode" appears before the monitor goes black and then switches into sleep mode.
I have used the Switch application to try and fix the issue, and I have also adjusted the resolution many times as it appears my Macbook recognizes the monitor but an image just won't appear on its screen. I just ordered a Male to Male DVI cable and mini DVI to DVI adapter to see if a digital connection would work. Does anyone know if this will work or of another solution to my problem? Thanks.

So I ordered a Mini DVI-DVI Dynex adapter and Male to Male DVI Cable off ebay for very cheap, and to my surprise, this set-up seemed to shake the monitor out of "Analog Power Saving Mode" into "Digital" since its a digital set-up and now I have a fully functioning, mirroring monitor. So I would suggest switching to DVI to correct your issue.

HDMI Monitor flickers

I have an VGA Monitor connected via adaptor to the HDMI port as a second Monitor to my Thunderbolt display. The VGA Monitor flickers and it was suggested to upgrade the firmware. But the system tells me the firmware is not for my system (Mac mini Model A1347 from autumn 2011).
How can I fix this problem?

What monitor(s)...?
If one has (Digital) DVI input, then you should use it on the HDMI port with the Apple Supplied HDMI to DVI adapter and a good DVI cable.
If both have (Digital) DVI input, then it would be best if the second one was also on a Thunderbolt/MiniDisplay Port to DVI adapter instead of analog VGA.

My HP 2010i monitor is displaying a power buttom lockout message

my HP 2010i monitor is displaying a power buttom lockout message and goes black once in a while. It also turns off

To disable 'power button lockout' hold the power button about 30 sec.
If the monitor turns off then it's maybe more a pc problem?
Does it shows 'no signal'?

Losing power/signal and no internet connectivity for WRT54G2-RM

Just installed router and using Motorola SB5101 cable modem and Comcast. Followed instructions and the router has lost losing power and needing restarts a few times. Have it installed by ethernet cable to my desktop, and using laptop (XP Pro Thinkpad P42). Cannot get internet connectivity and also loses wireless signal connection. I know there are a number of similar posted issues, and I am new to this forum. Any ideas?

Download and upgrade your router's firmware, reset and then re-configure it...
Follow these steps to upgrade the firmware on the device : -
Open an Internet Explorer browser page on a computer hard wired to the router...
In the address bar type - 192.168.1.1...Leave the Username blank & in Password use admin in lower case...
Click on the 'Administration' tab- Then click on the 'Firmware Upgrade' sub tab- Here click on 'Browse' and browse the .bin firmware file and click on "Upgrade"...
Wait for few seconds until it shows that "Upgrade is successful" After the firmware upgrade, click on "Reboot" and you will be returned back to the same page OR it will say "Page cannot be displayed".
Now reset your router :
Press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...Now re-configure your router...

Computer Monitor Flickers

My computer monitor flickers if we tap it on the side it stops, then starts up again, sometimes we go hours and not problem, other times it drives us nuts, We have a Gateway computer, it works fine except for this monitor problem, it was purchased in 2004, it has a "nvidia GE Force 2 MX 400 video card, I checked with Nvidia and tried downloading the latest driver but then the computer wouldn't start so I had to go back to a previous date so that the computer would start, do I need to look at getting a new monitor? IF so what sort of monitor would be best, someone said the resolution would not be good on a wide screen, but the only ones I have found at Best Buy and other places are the wide screens. I hope someone can suggest a solution so we can enjoy this second computer and stop hitting the monitor
thanks Lea

I'm having a similar flickering problem with the LG widescreen LCD monitor which came with our first Vista computer (an HP desktop, purchased about a year after Vista came out). It mostly only seems to flicker when I'm playing games with animations in the graphics (such as Civilization IV or Astral Masters). The most common suggestion I found (f.ex. in the HP Help & Support area preinstalled on my computer) was to increase the refresh rate. Doing this has not eliminated the flickering, but has lessened the severity somewhat (it just flickers as vertical lines or bars at 75hz; at the default of 60hz it flickered as both vertical and horizontal lines). I ran HP's Monitor Diagnostic Tool (which included a simple wireframe animation), and it didn't turn up any problems.
Hockeycanuckjc's suggestions sound pretty practical, and I'll try them. I've also seen on another thread on this board that Nvidia graphics cards (my HP computer has an Nvidia Geforce 8500GT) can have issues with the drivers, especially after Windows Vista has just automatically downloaded its latest updates -- so it's possible that the graphics card driver could be getting cranky (though I haven't yet confirmed or denied that theory in regard to my own computer).
I think my HP computer is still covered under its Extended Service Plan (though I'd have to check the sales receipt to be sure), but I want to do as much troubleshooting as I can before calling Best Buy tech support, so I'll be able to explain my problem more knowledgeably, and hopefully not have to jump through as many hoops as usual before they authorize an in-home service call.

Lenovo Monitor Flickers constantly

Hi All,
I have a Lenovo L197 Wide connected to a Server 2003 box (also lenovo) and the monitor flickers constantly. The refresh rate is set to default and I can't change it to see if it has any effect.
Anyone any ideas?
Cheers
Andy.

welcome to the forum.
are you using fluorescent lights nearby? if so, does the monitor still flicker with the light(s) turned off?
have you tested the monitor on another computer, with a different cable, with a different video card, or a different monitor altogether with the server 2003 machine to eliminate any variables?
if the above checks out then your L197 either has a defective inverter or its backlight is failing. warranty is your best option in this case.

Monitors flickering badly after Yosemite Install

Monitor flickering badly after Yosemite installed
I will be awaiting upDated drivers in a release soon.
I notice is very badly when I connect my iphone to ITunes screen
goes crazy flicker. . . . Anyone else having this issue ?

Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
     Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
     COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the
     computer and after the chime press and hold down the OPTION key until the boot manager
     screen appears. Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

IMac randomly losing power

My 2006 Intel CoreDuo iMac has started randomly losing power. Without warning it will just power off as if someone has switched the wall socket off.
I've managed to power it back up again about 4 times after which it just does it again.
Once power is lost the only way I can get it to work again is to keep taking the memory out, putting it back in, try to switch it on, take it out again, put it back in, try to switch it on again, etc. until randomly it works again!
I've tried resetting PRAM by unpluging everything leaving it 15 seconds and then nothing... I've also managed to do a CTRLCOMMAND+PR when it was working.
Now it's gone again
Anyone any idea what might be the problem here?
I have no AppleCare so the iMac is out of warranty and the internal DVD drive no longer burns properly either. Should I give up on this Mac and put the money towards a new iMac (with AppleCare this time!) or is it going to be worth trying to get it fixed. My thoughts are that the local Apple Service Centre might take ages to determine the problem and try various things and then might not even be able to fix it.
Could it be the logic board? Power supply?
How much is a new logic board and DVD burner?
Thanks,
Neil

There are a number of threads on the iMAC loosing power. Check these:

My iMAC was doing the same; it finally died and wouldn't power at all. The tech at the apple store stated they have seen a few bad power supply cables that are the cause of the issue.
