I have been a tech for 26 yrs now i have seen so many postings on here about bulging caps and so on but there is only 1 thing to do our workshop has 18000 dollars in test equipment alone there is a great reason for this the amount of vereables that can go wrong with nano electronics there is no easy fix to this problem it needs to be seen by a certified electronics tech this is your best chance of having this tv fixed correctly im not putting down other techs on this site but some things we can fix by computer network some we cant imagine even if this tv was in my workshop right now it would take us over an hour just to find and fix the cause

i hope this helps you sir/mam

Could be a lot of things, but most likely is LCD Inverter Board, which lights
the LCD display with white light.
Another possibility is loss of 24VDC switched power from power supply.

Possible sources of replacement LCD inverter boards:
www.shopjimmy.com, www.ebay.com, search for refurbished LCD inverter board.

Westinghouse 32H540S Remote Program


You have this backwards. The codes are in the remote. If you are using a Westinghouse remote, there should be no programming necessary. If you are using a universal remote, you can use the code search function to find a code that will control your TV.

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.

Won't turn on. Westinghouse SK-32H540S 32 LCD


Try leaving the TV unplugged for 30 minutes so the TV can reset itself.
If that doesn't work, most likely the TV has a power supply related problem. Or, it maybe something simple like a blown fuse inside the TV.
But, I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If the fuse doesn't fix it and If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem with the power supply and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.
