You may have a compatibility issue with your monitor. You computer may not be putting out enough power to support your monitor. Check your users manual on your monitor for output requirements. If the monitor's manual has a number to call, call the manufacturer to see if there are any compatibility problems between your computer and your monitor and calling the people who built your computer as well. Get as many scenarios as you can to find a solution. Hoped this helped.

Why does screen go black after a few seconds


Hope this helps.... Your monitor has an inverter issue. You know it's an inverter problem when:
1. Your monitor starts normally and displays the startup/desktop screen for a while.
2. Then it suddenly goes off, leaving a blank (black) screen or a very dim display.

To fix this black screen problem, change the inverter board (based on your monitor brand).

Sony sdm-hs75p runs for 5 odd minutes then screen goes blank?


h_e_l_l_f_i_, Have you performed the flashlight test after the screen goes "BLANK" ?? No!! You will not find the "flashlight" test listed in the OWNERS manual!! The test is a quick evaluation of the STATE of the units "switch-mode-power-supply". Did you repair the power supply to get online to fixya? The more info you tell me about your LCD monitor the better I can assist you. Is the unit really "BLANK" or is it just "BLACK"?? Can you SEE the WIN-desktop when a bright "flashlight" is held 1" from the screen at different angles? If you can see a faint image being displayed it means the SMPS is in partial shutdown and still powering the VGA to LCD interface board. If unit is both BLACK and BLANK, then SMPS is likely in full shutdown mode! I will assume that when you stated "runs" for 5 minutes, that it would display normal text and graphics as usual and NOT be wearing a pair of NIKE's runners footwear? Yes! From your description it would lead me to think that your SONY has a SMPS/INVERTER problem. You failed to state the age and or approximate TOTAL "ON" hours the unit has. (hrs/day x 350days x Years since DOM). It makes a difference in whether I tell you to trade up to a wide screen or have it repaired(refurbished with new SMPS/INVERTER or just rehab the SMPS on your own. hellfi, surely, after reading this you WILL go to YOUTUBE, (just fyi) and view some of the longer video clips of "LCD monitor disassembly" and typical "LCD monitor repair"!! You WILL be impressed at how much you will learn about how "the black screen of death" is dealt with. If this response helps in any way, please rate it on fixya. 12fixlouie lmistyrel @ aim.com Get back to me if further assistance is required asap!!!

Asus Monitor boes blank and comes back after power recycle


1. You can see images on the screen for a few minutes. That means there is nothing wrong with your computer.

2. When your screen goes blank, if you disconnect and then reconnect the monitor, it shows fine again for a few minutes before going blank (or dim) again. That means the problem is not with you video card.

3. It always shows the image after reconnection for exactly a few minutes before going blank again. yes? this means that there is nothing wrong with your cable.

Conclusion: Sorry, but you do not have many options. I bleieve that the problem is with your monitor that's going bad. Its far cheaper to get it replaced than to repair it.

Monitor comes on, then goes back off, rinse, repeat.


Well here is a test you can do. When the monitor goes black, take a flash light and hold at it a angle towards the monitor, if you can still faintly see the image then you have a blacklight/inverter issue. Another common issue with this is the capacitors on the inside. They will also cause this. If you dont see an image then the inverter will need replacing. As the steps for replacing all of this are quite long, ill post a few helpful tuts :).

For replacing the backlight:

For checking/replacing bad capacitors:

I know these arent your monitor but its generally the same idea with all of them. If this doesnt work it will be a inverter issue and if it comes to that just let me know and ill be glad to help :D
