Having problems with your Dell E152FPc 15" TFT LCD Flat Panel Monitor ?

Monitor powers on for appx 1 second then goes dark. LED is on.

\015 The green light stays on, but the screen goes completely dark after 1 second. Only by powering off then powering back on the monitor can I see my screen...for about one second than it starts all over. Cables all ok. Tried adjusting the display rate to 70Hz as one solution recommended but no difference. Monitor behaves this way on any computer it is tried on. Capacitor problem??? Transistor problem??? Bough this thing used and I was told it worked fine. Not!\015

Answers :

Hello,
You have a classic capacitor problem. If you are ok with soldering you should be able to repair it. You can remove the back cover and look for the bad capacitors, replace any that are raised on top. I can send you pictures of what to look for if you need them.
I had this same problem and found a capacitor on the power supply board was bad. The cap was a 1000microFarad 16V bi-polar capacitor with a temp rating of 105°C. No one in this town had a 105°C the highest temp rating I could find was 85°C so I used that. So far it's working but I don't recommend ever going with a lower rated part. The hardest part of the whole job was getting to the power supply board. Dell has some tricks to getting inside this monitor. Good Luck.

My monitor only comes on for a few seconds and then goes very very dark, although the content is still there somewhere. But here's where I differ from the majority, if I can get to run System restore, the monitor will work perfectly fine again until the next morning when I need to switch it back on again. Unplugging the power lead from the back and utting it back in again will relight the screen for about two seconds before it all goes blank again.
