Question about Dell E172FP 17" LCD Flat Panel Monitor

1 Answer

SCREEN BLANKS WITH POWER LIT GREEN

DELL 17" EP172FPb LCD monitor: The power button remains lit green while the screen blanks off. Even when accessing the menu, the screen will blank out. Obviously a problem with the display circuitry itself and not a video adapter problem.

    All caps look good but I did see what looks like dielectric on the underside of the pcb at transformer T753. I am going to try replacing that one as it is the only physical discrepency I could find. Thanks for the help.

Look for bulged or leaking capacitors on the power supply board. If you can solder, you should be able to replace them with the same type and rating and that may just solve the problem. I've had luck with a couple of dozen monitors so far.

Monitor L17AMTN flashes WinXP desktop, then blanks.


dmellman, Before you open it up, try this! With fully booted pc and WIN DESKTOP screen up, reconnect the L17AMTN . Have a bright flashlight handy so that when the lcd screen flashes on for 1 second and then goes dark, you will want to check to see if the desktop remains on the screen even though you think it went away. Shine the light 1-2 inches from screen at different angles. Has the desk top completely disappeared or is it still being displayed? Do you know about Cold-Cathode-Fluorescent tubes and their Inverter type power supply? I assume that this unit also has a "lay on floor black box switch-mode-power-supply" that is supposed to supply raw 12v-14v dc to the monitor? This symptom is typical of lcd monitor power supply failure, and or inverter board failure. Not to mention the fact that the CCFT's could be a bit tired from use. YOUTUBE has some videos on taking apart lcd monitors. also do search on web for "bad caps on lcd boards" or "bad caps in lcd monitors". I should think that this Tatung might suffer from swollen cap-itis. get back to me with results of your investigation. Im louie12fix on fixya or lmistyrel@aol.com just nrth of Windy City

Self-Test Feature Check (STFC) Your monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. If your monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:
  1. Turn off both your computer and the monitor.
  2. Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove Analog (blue connector) cables from the back of computer.
  3. Turn on the monitor. The floating 'Dell - self-test Feature Check' dialog box should appear on-screen (against a black background) if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains green and the self-test pattern will scroll through the screen continually.
  4. Turn off your monitor and reconnect the video cable; then turn on both your computer and the monitor.
If your monitor screen remains blank after you use the previous procedure, check your video controller and computer system; your monitor is functioning properly.

Thanks
