Having problems with your Compaq TFT5015 15" LCD Monitor ?

No backlight Hello I have a problem with my Compaq TFT5015. The screen is VERY dark , almost black but I can still see that something is moving when the monitor is plugged in. I have opend the monitor to look for bad capacitors but i could not see any just by looking at them. the reason that I looked for that is that I have a samsung syncmaster 214t that had that problem and I fixed by changing capacitors and they REALLY where bulb. I got the solution from here by the way :) I saw something abou


Answers :

You may have a bad regulator or a bad mercury bulb. Testing either requires a professional with the right equipment. This area contains high frequency current. The mercury bulb is extremely delicate and has to be disposed of properly. I would suggest taking this to a pro.
