Question about Westinghouse SK-32H540S 32 in. LCD TV

Open Question

Westinghouse Lcd Tv randon "No Signal" message.

I have the SK-32H540S which is a 32 inch Lcd TV. I have it plugged into my normal cable connection. Most channels work perfectly on this TV, but on some channels at random times I get a "No Signal" message and my screen goes black. After a few seconds the channel works normally again, but then a few seconds later it goes to "no signal" again. This repeats on on and on on these channels.

This didn't happen on my old normal TV I used to have nor does it happen on the 44inch Samsung lcd we have in the living room or any other TV in the house. I'm positive this issue has to do with the TV and not with my cable. I've tried calling Westinghouse but after hours of being on hold I have given up.

I hope someone can help me, thanks in advance

Hello, it sounds like you need to replace the inverter board, I believe this model has LIPS board which is the power board and the inverter board put in to one single board. You can find price and availability for parts by emailing parts@wde.com.

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.

The problem is cause by the transformer on LIPS inverter (Power supply + Inverter board). You could see an obvious burn on the 1 of these transformers ( There are total 3 black transformer on this board). The part number is 4302H.

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.

It is probably a poor connection through the coax. I would replace the coax and that may resolve the issue.

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.
