Question about Samsung HL-R5678W 56" Television

1 Answer

Samsung 1080p turns itself off

Our television is less than 2 years old and in the last month it has started to turn itself off. It happens most frequently when the TV is just turned on. There is no pattern to it at all. Sometimes it goes 5 minutes and sometimes it's fine for a couple of hours and then just turns off. It appears to happen the most when it's just been turned on after being off for several hours. Does anyone have a solution for this? We have removed the surge protector, checked all the connections, dusted fastidiously around the rear of the TV.....we're out of solutions here!

Re: Samsung 1080p turns itself off

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.

Samsung HC-P4752W Does Not Turn ON

The proble you have is an intermittant power supply or sweep power supply. Unless you can find a bad connection on the power and deflection board, this could be a very difficult problem to find. I have ran across this problem a couple of times, and after spending countless hours troubleshooting, I replaced the main board and all the problems were taken care of. The board part number is at and I found the board for you. it is located here: Good Luck

My tv shuts on and off every 5 min and turns back on by itself.

I had a similar problem on our 61" LED projection Samsung, It was about 9 months old, I called in the engineer (It was still under warrenty.), he updated the firmware on the TV. He connected his laptop to the TV, went on to Samsung,s internet site, downloaded and installed the latest update. We have had no problems since.
I hope this helps you.

Since the set is only 4 months old, it should still be under warranty. DO NOT open up the set as that will void the warranty. Call for warranty service and indicate that this is an intermittant problem. If you can report any pattern about when this behavior occurs, that info will be helpful in resolving the problem.

Keep us posted.

I repair a lot of these and a average tv lasts like 3 years . It is not like the old days. I suspect the lamp or fans or therm protector.

I would call a local tv shop see what they charge for estimate it might be worth his estimate to find out what it is.

Thanks doctor video

HELP! Fire Hazzard!

It sounds like your focus/screen block, the flyback transformer, or maybe a CRT anode lead is leaking high voltage. This could be a serious problem, or could be a simple one. You should not attempt this repair unless you know all of the high voltage safety issues involved with this TV set. Good Luck
