Sounds like The main power supply regulator section circuit fault. 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. 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.
Search the site by type in the "brand name" to your device; [Exclude the model number], in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

SOURCE: 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.

Your lamp has blown. Time to get a new one.

the hyperlink button doesn't seem to be working, but just copy and paste this link into your browser. It is linked directly to your tv's replacement bulb.

If it happens in heat it must happen in cooling. The indoor unit has nothing to do with if it's heating or cooling. You likely have 2 moving parts in the machine, the blower wheel and the swing fins. Turn swing option off, eliminate that. You get the rest...

Screeching noise coming from my tv


Is the sound coming from the speakers or from the actual television? If from the speakers, I would check all connections for the sound system. If from the actual television frame and housing, check for a fan ( to cool electronics) canned air or compressed air can work wonders for cleaning out dust which can cause mechanical sounds. If it's coming from the speakers, there is an electronic problem which is usually related to cable connection issues. Have you made any changes recently? If so, check those connections. Unplug them, and make sure they are securely plugged in. I would assume this would fix any problems, if not, there is a problem with one of your devices... I'm convinced you have a bad connection somewhere or a bad audio cable.

I have a ADF-242 that is having sound output problems


If the car was running when testing sub and heard noise this could be engine noise and an inline filter would cure that problem and also have a good ground no more than 15 inches away from the amp.And good metal contact for ground.

No sign of life in external notebook speakers


  1. If the powerlight is turning on some times and off sometimes, Then it may be a problem with the powersupply connected to the speakers. Check it.
  2. If the speakers are on and are not playing, Then try playing some music through alternate source like ipod,walkman etc.If the speakers are playing with alternate music source, The try reinstalling the audio drivers of your note book.
  3. If not then your speakers might have fried up due to some reason.
