How to fix your Westinghouse LCD TV (Pt1)

This is the first of two videos I decided to make showing a do-it-yourself way to fix your Westinghouse LCD TV when you suddenly lose the video (the TV screen goes black but the audio remains). The issue is most probably the Power Supply Board also known as the Inverter Board. Find out here how you can fix your TV without the help from Westinghouse's terrible customer service. I did it and so can you!

Hi,

Reading the many forums, it almost seems like everyone who got a westinghouse set has pictures problems within 1 year. I have a 37" that went out 3 years ago. I finally just pulled it out of the closet hoping to repair it finally.

I'm surprise there aren't more videos with people fixing their sets. Has anyone been able to fix their inverter board instead of replacing? Is there a fix or is the board just crap and you hope that getting a refurbished new one would work and not crap out.

@battalionofone Hey man, well, I don't know if it's possible to fix the inverter board. I mean, it might be if you know how to replace only the little part that burned out but if you're not proficient enough (like me) it could be too risky. I believe that $100 for the whole is easier. Good luck.

I have a 32H540S (32 inch LCD). If you've been having the same issue as I described I'd say with 90% of certainty that the solution is also the same. Good luck my friend.

I had the black screen problem as well a year ago. The power supply board was the issue. It was one of the 3 black tranformers on the board. It was fried and I could see the soldering had been burnt and blackend. I replace that one part my self with circuit soldering and the part for $30. 3:39 shows the transformer right in the center. I recommend checking the boards components before buying a complete board.

Totally forgot to follow up. But...for my 37in tv. The replacement inverter I bought salvaged from a vizio set worked fine for my tv. After I got my old inverter card out, upon "really close" inspection, did revel that one of the capacitors had a some small burn marks.

@ezman86

Yeah, sounds like you have the same problem i had. It is most likely the inverter board. I opened up my tv and used ebay to find a matching inverter board. It is a pretty easy swap. If you'retech savy, you could probably fix it yourself. There is definitely a capacitor that is burnt out. You can tell cause the board turns on and then off and you still have power and audio. The inverter board is detecting a short & shutting down to prevent overload.

oh im having the same problem, the tv turns on for 1-5 seconds and then the picture goes dark, on the other hand, the audio is on. so i was wondering if u know what to do

This can be a number of a problems with the power board. Usually its caused by bad capacitors (cylinder-shaped components), transistors (chips with 3 leads) or transformers (big blocks). What you call "transistors" are actually just the cables for the CCFL backlight bulbs. They have 2 wires (+ color and - white). The power board was definitely the problem, but $110 is a lot to spend on it. Try online sites like shopjimmy for a variety of parts and decent prices.
