Hi soccerdiva9z,
Power on the unit in the dark room then shine with the flashlight directly in the screen, you will barely see the images. This is because your backlight is not functioning. The following reason is the caused.
1. Power supply - missing B+(supply voltage) coming from this board feeding the inverter board. This is caused by faulty transistor, dried/leaky electrolytic capacitor, open fusible resistor.
2. Inverter board - even the B+ is good from the power supply, if the fuse, driver transistor, driver transformer is faulty no output to the backlight resulting to black picture.
3. Busted backlight - even inverter board is good but if this is busted resulting to black picture also.
Diagnosing the fault is technical and if you don't have necessary tools and test instrument and can't fix it yourself, I would advice you to look for an experienced technician to isolate the problem.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

    It is the transformer on the inverter board. You can try replacing just the transformer for like $30 but it would require sodering. But you can also just replace the board itself for about $160

It's a bad capacitor on the power supply/backlight inverter board. Replace the board and you won't have any more problems.

Westinghouse LCD TV SK-32H540S, 1 year old. When I turn it on, the screen works for about 5 seconds, then goes dark; power is on - sound still works but no picture


1 swollen Capacitors / Replace
2 blown Diodes on inverter board / on some # 508 or 908
3 bad transistors in inverter bad will appear overheated powdery coat
4 replace inverter if you cannot locate problem on it
there is a safety built into the high power back light supply and that is if too much current is drawn or light is shorted it will not burn up
or hazard high volt shock to user.
capacitors and diodes driven with power transistors
look for darkened spots on the board to identify hot transistors
puffy tops and leaky bottoms of capacitors

when you turn it on does the bottom or top of the screen show image a Milli second before the other it should be evenly the lag
is the one requiring more amperage

Westinghouse sk-32h540s TV, VGA input, image can't center.


Hello, two things, one try using the TV with the native resolution of 1366 X 768, and secondly try updating your video card. If you are not having this issue with the TV on the other inputs than most likely it is a settings issue with the laptop. Please rate this comment if it was helpful.

TV Turns on picture comes on for 30 seconds then picture goes off and sound stays on. Even after leaving tv on the sound stays but the picture does not come back on. Its a westinghouse SK-32H540S


This is not the fix for this TV. I guarantee that none of the capacitors exhibit the common bulging characteristics of a faulty capacitor. The common answers to everyone's questions are to replace the capacitors. Most likely the culprit is the inverter board.

Picture comes on for 15 seconds then turns off, sound still works


One of the transformers on the inverter section of the power supply board has failed. Part can be found on line ($29.99). Also check for faulty and poor solder connections.
