Question about Dell E152FPc 15" TFT LCD Flat Panel Monitor

2 Answers

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

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!

    Thanks! I will try taking a look and see if its do-able for me, although I am an inexperienced solderer.

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.

Monitor goes blank less than a second after turning on.


Sounds like either there is a bad connection from the computer to the monitor, or the monitor has a faulty power regulator, causing the monitor to overheat prematurely, and shut off.

I switch on my PC, ensuring that all cables, leads and power supplies are connected properly. The tower powers up no problems at all. I switch the screen on, the green led lights up, the screen is completely black. A blue box appears centrally on the screen with the text 'power saving mode'. The green led light turns amber and then the screen just goes black.

Please don't suggest going to control panel, as I can't get that far.

The problem can be bad power supply due to bad caps, bad inverter circuits, or bad lamps. Open it up and look for bad caps first then report back what you see so we can guide you further, see example of failed monitors due to bad caps; http://s807.photobucket.com/home/budm/allalbums

if you look closely can you see a very dark image on the screen? your problem is usually the result of the backlight on its way out, these are very hard to replace so you will need to take it to a profesional, in most cases it is cheeper to buy a new screen.
