Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

It sounds that the back-light inverter section circuit to your TV is faulty. It is very difficult to predict which part is defective, as per your prescription here. It will be best to contact any service technician. If you wish to get some details, check the site linked here. Pull up older posts.

My electric went off yesterday and when it went back on my tv wouldnt turn on it was working fine before the power cut we have changed the fuse but still nothing is there anyway i can reset it to make it...

you said you changed the fuse. (inside the tv)double check to see if its blown agian if not. keep it unplugged for about 20 minutes to reset the surge protector onboard . if you have done all that the fuse didnt protect your tv from the surge and it gone. IF ITS CONNECTED TO A SURGE PROTECTOR unplug it from that and plug directly into the wall TRY THAT FIRST let me know if this works.

You could have possibly damaged the micro controller within.If the set come on in cold condition it would reset on it own. In such a case try to reset accordingly... or else you will need expert help

The power went off and when it came back on the tv wouldnt come on but the timer light is lit

First thing is to unplug the TV for several minutes, replug, Power LED shouls flash for around 90 seconds then go off. Try to power up then.
If the power LED does not stop flashing , or the TV will not turn on still, it will need a repairman.

TV wont turn on, makes buzzing noise and shuts off

I have two RCA HD52W59 TV's. I have had one for 3 years and one 4 years. The one I have had for 4 years is giving me the problem. Last week the tv turned off while watching it. It wouldnt come right back on. 10 minutes later we tried and it worked fine. the other night the kids were watching and it turned off and smelled like something burning. I tried turning it right back on and got no power at all. I tried to turn it on two days later and it made a buzzing noise and the green light went out. Never did get a picture, no powering up on the screen. Any ideas? Don't want to spend alot of money. Really loved the TV hope it isnt junk now. Better yet I hope the same thing doesnt happen to the other one I have.
