Nothing happens when pressing power button. The Power LED doesn't light. I tested the fuse : it's good. Thanks for your help to diagnose ...
Check the tv power supply board,that board where the power a/c cord plug into it.Most common problems on these power supply board are dying and leakages capacitors components parts.Check the power supply board carefully,if u have dying or leakages capacitors parts,these capacitors parts will bulges ups,will not have a flat cylinder heads like the rest of the other capacitors coponents parts.Replaces all these dying and leakages capacitors parts with the same Miro fared and the voltages little higher like 5 to 10 volts higher,the power supply board should not have this problem again.U have all equipments to do basic soldering works and u understand basic electronic wright?Then u should have no problems by replacing all of these dying and leakages capacitors parts that are bulges ups onto it cylinder heads on the power supply board.If u can't do this,tries websites like Shopjimmy.com,eBay.com to by a whole new refurbish power supply board for the replacement.

That sounds like the backlight inverter board. Check ebay for the board or a repair kit for it.

its in the power suppy section,most of the lcd monitor has this problem,try to check the capacitor electrolytic or replace all th 16v capacitor

I buy and sell these monitors (Dell E17FP) the problem is with the transisters (Q739, Q740, Q759, Q760) they short out and the monitor will just blink on and off. You have to desolder them and test them with a simple battery and light circuit. The reason they blow is because of the dirty solder joints by the transformers. If only on pair of backlights work the problem maybe transisters Q751, Q743. I home this answers your questions.

Just wanted to say Thank You for the info on this site. I had the same problem as previously posted. When powered up, the monitor showed a fast flash of the desktop and then went black, with the power indicator flashing green. I read the posts, purchased the capacitors and the 4 - 2sc5707 transistors through ebay. I ordered them on the 6th and rec'd them today. I only had one bad capacitor and one transistor that checked bad, but I ordered 5 caps and 4 transistors. When ordering the caps be careful of the height of the caps. I found this to be a problem because I ordered the 50v, 105 degree Panasonic caps that didn't fit with the enclosure attached, so I used the 4 good caps removed previously and replaced the bad one with a 470uf, 50v. 85 degree cap from Rubycon I found among my spare parts. Installed the parts and the monitor is working properly (for the last two hours) so I'm happy for as long as the repair lasts. Thanks again for the info.

Do you get anything at all on the screen--like white writing at startup?
Even if your video drivers have become corrupt, they are not used until Windows actually starts.
It very well could be the flourescent backlight has gone bad. Can you adjust the brightness/contrast at all to see anything?
If those controls do nothing for you, then you're looking to get a new monitor.
Your monitor does have a sort of power supply for the backlight and that could be bad, but if you're not into taking it apart, then you are far better off buying a new monitor.
