i was having these same problems with the screen going black, and i found that when i hit the back of my tv it would work sometimes. so, i improvised on some of the advice on this page and so far no problems. here is what i did (its very easy):
1. lay the tv on the floor and take off the back panel. (i think 12 screws)
2. on the right side of the tv (as you are looking at the back) you will notice a large metal covering that is held in place by 6 screws. unscrew these and remove the metal cover.
3. you will notice that the three screw holes on the left side of the board have some sort of metal or solder around them, in sort of a star pattern. when i looked closely i noticed that most of the metal (solder) was tarnished, or kind of blackened. (this must mean that the ground screws werent getting a good connection and this would explain why it would work sometimes when i hit it because it would vibrate the screws enough to get a good connection! )
so, take a pencil eraser and erase all the black or tarnish off the metal surrounding the screw holes. thats it! (to be safe i took some sandpaper and cleaned up the screw holes on the back of the metal covering, but i dont know if that was necessary)
at this point i followed another gentleman's advice to do a hard reset. this involved unplugging the 8 connections although i dont know if this was really necessary because i believe my problem was a ground issue. i did it just to be safe. his advice is on this site if you want to do this step.
4. i put everything back together and it worked! i performed a soft reset at this point which puts your tv back to factory settings. just go to menu>setup>reset>return to factory settings? yes
this will turn your tv off and back on. that's it. so far so good for me.

I had the exact same problem and I fixed my Westinghouse 32 inch by replacing the power supply. You can purchase it at
I takes about 15 minutest to replace. Just take the back lower panel off and replace the power supply. Mine works like new now.

I have over 10 years experience in electronic tech support. Currently I work for Viore customer service. Our customer service phone number is 216-454-0868.
I know this isn't what you want to hear, but the problem you've described can't be fixed with troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. The repair will cost a minimum $250 to $300 with parts and labor. If you're interested in going forward with repair, take the TV to a repair shop in your area to have the problem diagnosed. The tech will give you a copy of the work order showing the part(s) needed to complete the repair. Then you'll call the above number and ask to speak with Raphael at ext. 3115. The work order will be forwarded to the corporate office and they will contact you with the price of the replacement parts. You will be charged for the parts directly to avoid any markup by the repair shop. The part will be shipped directly to whatever repair shop you choose.
I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. I hope I've earned a positive rating from you today.
Please let me know if I can be of further assistance.

Open the cover and look for the burned componet.Usually it must be a condenser. Rarely a resistor.If it is a condenser just replace it with the similar one. Note the polarity while replacing. If it is resistor need to check the associated circuit for over load. If you not sound in electronics reffer to an expert.
