I have a Westinghouse WD55UT4490 TW-04401-L055A 55" LED that I can't get to turn back on.


Try the flashlight test and see if you can see an image on the screen that way...do you have sound? If you dont have either then chances are its the power board, however sets made by Funai are known for LED lamp failure in the panel

If there is sound output to all channels, and oly picture is absent, the backlight inverter board should be suspected.

Unit comes on when pluged in does not have a picture, will not power off unless you unplug it. screen is lit up and has a blinging action


Short in the power circuit will cause it to stay on until the power is removed. The fault you describe is probably down to a fault on the circuit board. The power capacitors could also be faulty, and the lack of an image would seem to confirm this.

I'd suggest that the monitor should be taken to a competent technician for further analysis and possible repair. I'm not sure what you mean by blinging action, but if you mean an audible crackling or noise, this suggests arcing of power to earth. If you mean a flashing screen, it could be the capacitors trying to fire up the HT circuit but leaking to earth as they do so

When I turn on my Philips rear projection tv, the power comes on but no picture or sound. power light stays lit solid. If i adjust slowly the screen or focus controls, the picture and sound will come on....


could be a number of things....check for bad solder connections on circuit board around Flyback xformer and also check connections on conversion module for colour problems....double images red , blue , green popping in and out.

Westinghouse LCM-19V7 powers on, but picture only stays for a sec


It's probably bad capacitors on the power supply board. These monitors are notorious for having the electrolytic capacitors blow out; cheap components! I would suggest replacing the two 1000 mfd capacitors and the three 220 mfd capacitors with 35 volt components from Radio Shack. That fixed one of my LCM-19V7s but not a second one which seems to have some other power supply problem.

32inch westinghouse LCD TV flickers/slighly shaky picture-LTV32W1


try reseating the LVDS cable inside the set it is the multi wire connector from the main board to the LCD panel (top portion of the panel). if that doesn't look to see if the back lamps are remaining lit during this problem. if they go out the problem may be power supply or inverters (lamp power supply).. some panel makers make these available as a seperate part, some do not and the panel must be replaced. if the back lamps stay lit it is the main board. start with the LVDS cable first.

It is worth fixing but you have to replace the power supply. It is a fairly common problem with the Westinghouse units.
