Question about Mag Innovision 19" LCD Flat-Panel Monitor LT916S
Like others here I start my computer and turn it on, and everything looks fine for about 1/4 of a second and then it goes black while leaving the power light green. I can only see the screen again after turning it off and on, but that's only for another 1/4 second. I followed what was listed here. http://www.fixya.com/support/t122207-monitor_deosnt_turn Monitor worked for 20 minutes then shut down again. Now you can only get it to work for 1-2 seconds. Please help.

Guide2u is correct! try to use a good monitor to confirm first!. and i think you have fault oscillation in power section! maybe you have defective parts! or change value resistors or capacitors!

The root cause of a PSU failure maybe something like a fault with the backlight inverter. If the current draw is high but just under the PSU shutdown point then the PSU can run really hot. The increased voltage rating of the new caps will not compensate for their lower temperature rating if the PSU is running very hot. Theres an scary article here about the construction of cheap PSU's from China that do not meet the stringent safety standards of the west. http://www.electricstuff.co.uk/acadapter.html I think PSU's are awful things just waiting to burn your home down. I always unplug mine after use because the power buttons on most equipment these days does not remove the mains from the input to the PSU. I sleep better that way. Please be careful.

How do you know that your LCD is the real root cause of this issue? I suggest you try to use a KNOWN GOOD MOnitor/LCD to confirm it first.
