Red light is on in front and have no picture


Good day..


That problem is usually cause of bad capacitors on the power supply section..

As you stated your TV works fine and after a minute the red light comes on...

That symptoms is cause of bad capacitors..Normally bad capacitors can check visually if the capacitors look like leak/bulged on the top that is the indication of bad one but not all bad capacitors are bulged some are not so in that case you have to used a special meter called capacitance meter..

This is the sample picture of bulged capacitors:

The tv turns itself off periodically. Sometimes it goes for hours and other times it happens several times in a 5 minute period.


I suspect a bad connection/dry joint in the power supply.
Look for regulator I/c's on heat sinks. They are favourite to get dry joints and anything that is heavy like transformers and chokes.

Tv started to shut off here and there, then the


Hi,samsung has 3 major failures.The 1st one is the lamp, which averages 6000-8000 hrs 2-4 yrs.When it's about to go bad it shuts off and on or image won't come at all.You can find your part here:http://www.discount-merchant.com/SearchResults.asp?Search=BP9601472A Another problem that causes tv to shut off is the ballast,which is the board that powers the lamp.It makes clicking sounds and will cause pic to flicker.The other problem is the color wheel .The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will get color distortion ,black and white picture and sometimes you will hear humming noises.Have a bless one!

TV screen goes black, sometimes for hours


This model series had a odd problem that caused this. It was the Hoizonal wire connctors for the yoke. If my memory serves me right, the Yoke wire harness went from Yoke to Yoke and plugged in at the casing of each yoke. What I found is the solder connection on the small board of each Yoke was intermitent. Please be careful if you choose to tackle this. It is in a HV Area.
Hope this helps,

Probably a bad Inverter board. I have a Dell 32" LCD TV but it has a Samsung Panel inside, found a burnt transformer on the inverter board, Still trying to find a replacement.


My TV comes on for a second then goes black, power still shows on but no picture. 1.5 years old

If you are not a tech person, take it in for service.

Sounds like a bad digital board to me. Not too hard to replace in those models but, you do have to write down a few settings before replacing it. These settings are available in the service menu. Any questions let me know tvtek@msn.com
