Question about Dell E152FPc 15" TFT LCD Flat Panel Monitor

LCD monitor no display - flashing power button

I have a Dell E152FPc 15" LCD Flat Panel Monitor. Bought it used. It was tested and working before being mailed. When I powered it up all I had was a black screen and a flashing power button. Pushing the power button does nothing just keeps flashing. Any ideas?

    Hate to criticize but that wasn't very good advice from a GURU. The problem is clearly related to power since pushing the power button has no effect. If it were a refresh rate problem the user would still see a POST boot up sequence.

Hate to criticize and then not help out. I have this exact same problem with one of my E152 Dell Displays. I have read around and this whole line of displays seemed to have trouble. I found many issues like this and no solutions.
So, I like to tinker and tinker i did. I opened the case, removed the screen and went straight to the power supply board where I found two burned out capacitors.

Found a great source for replacement parts and instruction to replace the caps at BadCaps.net
Let you know how it goes.

    GOOD NEWS JSGreen! This problem is solved.

    For about 25 cents in parts and an hour and half of dissaembly/reassembly time I am about to put my failed E152 Dell Display back in service on the shop floor.
    I boutght about 20 caps from Newark Electronics. I still have 8 other E152's out on the shop floor and judging from all the hits on the web with this monitor and this exact same problem I fully expect some of them to fail.
    Contact me if you want me to step you through the repair process.

Hello, my best guess is that the refresh rate is set for a crt monitor. hook your old one back up, if you can. and change it to 60 hertz or 70hertz. go 2 display properties then settings then advanced; then monitor. set the refresh rate as i said and turn off the computer, hook the new one back, and you should be good to go. good luck! and please rate this solution. if you need further assistance, reply

    hello, one more thing i wanted to say, most people when they replace the crt monitor with a lcd, forget or don't know this. a crt is set at about 85 hertz. the lcd monitors don't handle that. the refresh rates for lcd's are 60,70,72 hertz. so do like i said and you should be fine. have a nice day! reply if you have trouble.

    then why not offer a solution instead of neg.comment? (guest) also guru does not mean you are right all the time. and i do this on my spare time at no monetary gain. solution offered is based on past experience on flat panels of different brand. added to the shop. nothing displayed until crt was reconnected and refresh rate was set at 72 hertz. then flat panels were put back and worked perfectly! no post was displayed, just flashing power light. before that. (explain why, if the statement you made is correct?)

How do I get rid of flashing Display mode out of range message


Terry,
That monitor only has VGA in port. So it sounds like the computer VGA out port is not sending a correct 1024 x 768 at 75 Hz signal to the monitor. The problem could be a defective video card.
Thank You,

No video. Power is good but no video signal from cpu


Try this:

While powered and connected to the computer, shine a very high powered flashlight on the screen. You should see a faint shadow of the display from the computer. If so, your inverter board or backlights are blown. If not, the LCD controller matrix may be blown. Either way, I would suggest just getting a new monitor.

My monitor do not work right


Are you saying that you can faintly see your desktop or just the reflection of your desktop??
if you are saying you can faintly see your desktop it means that the fluorescent light isn't firing up properly, take it to a repairman or if its under warranty, take it back for a swap or a refund.

After monitor is turned on, it goes blank after a few seconds...


Sounds like the cable that connects the monitor to the computer hass a loose wire connection in it.
When it turns green, try flexing the cable near the connectors and see if the color changes on the monitor. I suspect that you have a wire in the cable that was not soldered properly by the manufacture.
If it changes color, I'd contact who you bought it from and have them replace it.
Hope thid helps. Bud
