Question about Samsung Televison & Video

Open Question

I own a Ln37b550k1fXZA Samsung tv. It's flickering after a few minutes turning on. I heard about the Samsung bulletin for cutting the jumper jp852 or jp854. I looked and cannot find any of those jumper. I would like to know if there is abother jumper I should know about or should if my TV have another problem.

SOURCE: my samsung dlp tv model hl-p5063 w cuts off multiple times while playing

Hi, I had the same problem on my Samsung.

I removed the rear cover and cleaned the cooling fans, there were (2), it has worked fine ever since.

Be careful of course working with electrical boards.

SOURCE: TV fliockering on and off

Unfortunately that's an indication of the crt going bad in a Sony.
You can turn the G2 voltage down on the flyback or have a tech rejuvenate the picture tube but either of these are only a temporary fix..
The flyback is the rather large transformer with a red (anode) wire coming from it and attaching to the crt. (looks like a suction cup).
There are two adjustments on the back of the FBT, one is screen (or G2) the other is focus. With the unit on turn the G2 counter clockwise just a little and the picture will get slightly less bright. That should stop the picture from blinking out - or doing so as often. But again, it's only temporary!
Good thing Santa's almost here... :)

If your set was manufactured around July 2005, you may need a firmware upgrade to solve this issue. On the Sony website you can enter your model # and serial # to see if you TV is affected. If so, it is easy to have done and may be free from Sony. It sounds like the issue they described in the writeup on the required formware update. I had mine done within few months of when i bought it (purchased in Dec 2005) and it has been working flawlessly since.

Good luck!

This sounds like a repair issue. I do not believe there is any in-home troubleshooting that you can try that will fix that particular issue. I would call Samsung tech support to see what their opinion of the problem is. Their number is 800-726-7864.

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. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please post a comment if you need additional assistance so that I can help you further.

Samsung tv model LNS3241DX flickers


I'm not sure of a jumper wire to cut, but one of the first things is to clean out the dust that has accumulated on the electronics. You can blow out the back with compressed air or disassemble the TV case and dust it. Sometimes a layer of dust can cause excessive heat to build and shut off any type of overload circuit. Good luck!

SCREEN FLICKERING


The power supply module in this tv is part number BN44-00341A,
Samsung's dealer info says to:
For BN44-00341B; cut and remove jumper JP852.
This jumper wire is located just below the part number stamp on the pc board, I've done several of these and it cures the problem.

Samsung picture flickers


Pull the back off the tv. Look at the power supply. Find jumper designated JP854 on power supply. Take a pair of wire snips and cut that jumper out of the circuit. Put the tv back together. That's it.
