Westinghouse tv has a flickering red light but will not turn on

I had the same problem on my Westinghouse 32 inch TV. The internal main power supply went bad and had to be replaced. I had a TV repair shop do it. It was about 8 years ago. Haven't had a problem since. I think it cost about $70 for parts and labor. Nowadays TVs are pretty much a throw away item if they go bad. TV repair shops are getting hard to find plus the cost of TVs has come down so much sometimes you can get a new set for what the repair would cost!

Power board

Check and replace the damaged component/s at its main board. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

your power supply is failing replace it

Ok you have a lot of things going on here. Your first thing with the lines can be your T-con board or your Signal board or the screen itself. The second thing black screen you would have to be more specific? Is your back light on and you have no image? If that's teh case then I would replace the T-con board or the Signal board. If by black screen you mean there is no light on the screen from the backlight inverter then your BAcklight inverter or the backlight itleft might be bad. and ontop of that you might have the problem that we started with also. You can get westinghouse parts from www.interliquidparts.com You have to order by part numbers so you have to get the number from the actual part of your TV.

hi right now samsung is the best tv maker out right these problem dont happen with samsung what would be good to do is call them and let them know your problem cause you have a year protection on it thats if it less than a year

is the picture clear when on? if yes, does the screen go black after a few seconds. if yes, sounds like you need a back light inverter!
