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

    Had the same problem. My fix is only for guys who are not techies and will do more damage t a board when trying to solder a new part onto the board. I bought a Westinghouse 56.04073.011 Power Supply / Backlight Inverter for my Westinghouse SK-32H540S from Shopjimmy for $82-00 http://www.shopjimmy.com/westinghouse-56... Pulled the black cover off the TV. Then I loosened the 6 little screws that holds the board, plus I unplugged the little plugs, screwed the new board in place, reinserted the plugs, closed the back panel, reconnected the TV and WALLAH.... it works perfectly. It took me all of 10 minutes. There are, however, 2 different boards available for this tv, so open the back of your tv and check the part number of the board.

Take a strong light and put it up against the screen. Do you see a faint image? if yes, then your backlight has failed. Could be a lamp, inverter or power supply issue. Not for DIY'ers.

I have a Model #SK-32H540S Westinghouse LCD TV about 6 years old when turned on, goes thru Westinghouse logo, then picture lasts for about 8 seconds, then goes dark. I need to know what part I need.


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

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.
