Having problems with your Dell E152FP 15" Flat Panel LCD Monitor ?

Blank Screen I came home to a blank monitor.... the on/off button keeps blinking and won't quit. Tried shutting it off and unhooking everything still nothing... i could hear everything starting up but couldn't see a thing and button still blinking..... Tried hooking it up to a different computer using their cords same thing.....any ideas???????


Answers :

This is the power supply/inverter board that is failing, or has failed. This is the symptom, but it usually fails slowly - for example, it may take a few seconds to come out of powersave mode...then a minute, then 10 minutes, then an hour.

It's usually caused by the capacitors going bad, and if one is bad, it can take out some of the others, which is why it usually is a slow process to fully fail.

You can purchase an inverter board online - do a search for dell inverter boards, there is a couple of online resources, and they are usually around $50.

You can try opening up the monitor and pulling the inverter board (I'd only do that if it's out of warranty, and you don't mind taking a HUGE risk wrecking the whole thing - they are not very easy to disassemble) and replacing the capacitors - only if you have some electronics skills and can solder. The capacitors, which usually are the culprit, are probably less than\015\012$1 each, but replacing them isn't a guarantee to fix it, there may be\015\012another component on the board that has failed as well.

The cost of the inverter board is almost as much as what you can buy a used monitor on ebay for. It may not be worth it to try to replace the parts unless you're adventurous.
