Question about Dell E171FPb 17" Flat Panel LCD Monitor

1 Answer

No power I was given a dell e171fpb yesterday. First time I plugged it in, it took hours (overnight) for the displat to come up & power light to come on.. Once it did, it looked fine. I was told that this was the case from the person who gave it to me as well. I brought it home, plugged it in (using the same power cord, but not connected to my pc) waited hours (12 or so) and nothing. No power light, picture etc. Any ideas?

The screen goes black how can I fix this

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed Dell monitors to get some ideas what to look for:

Black screen when the power is on.

Common failure in the Dell are shorted transistors or bad caps in the inverter ccircuits, bad solder joints, bad caps in power supply. I would try it on another PC first, if it still does not work, you will have to open it up. Please look through my pictures of failed Dell moniotrs to get some ideas.

Colored vertical lines on monitor

Have you unplugged the power cord to the LCD? Let it sit for a minute, then try it. ALWAYS buy a UPS and plug any computer devices into it. Doesn't have to be big, a $50 unit will protect it from dangerous voltage surges.

I have A "Dell" E152FPc, and I have found an open transistor (Q201) on the Power Supply Board. My monitor comes on nice and bright for approximately 2 seconds, then goes dark; the power LED is steady. The voltage to the PWM IC is waky.
Before you try any hardware troubleshooting go to your control panel and turn off any power management options.

Dell e171fpb lcd monitor

The driver tabs between the LCD panel and it's controller board have failed.
These are very fragile and not repairable for anything in the cost effective range.
Best option is to either find a new panel to replace it, or get a new monitor.

Try first unplugging the monitor and the computer from the wall for 12 to 24 hours. If this does not work, hook up another monitor to the puter to see if the problems with the puter or the monitor.
