Re: mag LT776s monitor goes black
Hi this is the way how to examine
what's wrong with your LCD monitors. After you turned it on and the screen went black, you have to check that if you can see the image on the screen or
not by shining a flashlight into the screen, not directly but find the best
angle to the screen and take a look very closely. If you can see the icons or
any image, there will be a minor problem. This is because of the lamps inside
screen. Some of them were broken and it is very easy to replace. If you cannot
see anything on the screen, there'll be some problems with inverter board. If you
have soldering tool and want to fix it by yourself, check the caps first. It
may cause this problem. Some caps might show leaking or burn spot on the board
because of too high temp. If you don't have soldering tool, you better go get a
technician to do so.
Hope this help!! If anything I can help you with, feel free to let me know. Thank

get a bright light or torch and shine it on the screem if you see any faint image then the problem lies with your backlight, sometimes connectors come loose and thats your best hope. if you have a warranty of any kind its time to use it.
Your first step in troubleshooting this problem is to plug in another monitor to your computer. If you are having the same problem it is related to your computer. If the second monitor works fine then your original monitor is shot.
Have you checked the HZ that you are using the monitor in windows ? If set at a very high level (for example 100hz) it may damage the monitor as it is not supporting it. (and maybe this explains the reason for the shutoff as a means to protect the circuitry)
17 inch TFT/LCD Widescreens monitors are ussualy optimal at 1280x800@60Hz.
Right click on Desktop-->Properties-->Settings-->Advanced-->Monitor--> At this point check the Monitor Refresh Frequency.
Check this first and if this does not solve it then we can proceed to more serious hardware troubleshooting.
Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages. Good Luck!
This is not quite clear.
You say no image at home or at school
but worked at the store
Did you see it working at the store?
Check the cord sonnector for bent pins and or replace the cord- then come back
I have the same problem except it usually happens after Ive left my computer idle for a while... i.e . Overnight, I usually turn off the monitor and I hit the button after I come back to turn it on. I get the same flashing light for several minutes. This has been a problem for several months, but only recenly have i gotten the same error message you mentioned. Each time ive booted the computer up cold or restarted it has worked fine but this time it took longer along with displaying the message:
Top Left to Right: SH770 P001
Bottom Left to Right: AU M170EN05
Anyone else who can clear this up?
