Question about Samsung TXN2798HF 27" TV

Open Question

I have a samsung tantus 27* hd ready tv with a dyna flat screen =

It is a little over a year old - recently during the showing of commercials the picture is wavy - this is not true when a prime program is on - but usually only during the commercials - i thought maybe it was the type of film being used - but the problem is bizarre - the picture becomes markedly wavy to the point where you cannot watch it - i have tested the cable signal but it seems to be in the tv - any suggestions - OR what do i tell a repair man if i take it in

    Hi dburgess005, I want to help you with your question, but I need more information from you. Can you please add details in the comment box?

    Is this on all channels? Have you had the opportunity to check using a different TV? The fact that only commercials are affected suggests an intentional change somewhere; perhaps the commercials are broadcast in a different format not supported by the mode to which your TV is set. It is possible that the routine for processing the commercial format is not working properly, but it's not likely. Try going into the menu and experimenting with different video formats or modes to see what they do, and take notes if one duplicates or bypasses the problem. (Usually the worst that happens is an incorrect mode crops the picture or distorts it horizontally.)

Do you get any indication of power to the unit? Mine didn't.. the light next to the power button didn't come on. Turned out it was just a fuse inside the unit. So, take it in for repair and hopefully its a simple fix.

Your correct, LCD's don't burn. This sounds like a defective main control module. I would take it in as soon as possible to have it looked at.

My Hyundai tv 74 cm The color it not show good


Nice big screen but CRTs are getting old So, if you can't set correct colors with your Hyundai it might have some serious issue with tube. Probably replacement might cost you more then a new new 27" Flat Panel. See some tutorial and info about bad color of CRT

Hitachi rear projection LCD with yellow blobs on screen


I have the same tv and the same problem, but my yellow is a cloud around the outside of the screen. My tv was recently moved, and a repair shop told me that sometimes in a move these tvs light engine takes a shock and causes a yellow "band" on the screen. I am hearing that these light engines are not cheap either. Hope this helps you.

My 32 inch samsung lcd tv has got faint black lines running down the screen ,its nearly 4 years old but i expected it to last longer than that,and ive had sky hd box recently would that have anything todo...


Are these lines on both side of the screen or what location are they in? They can be caused by watching 4:3 television with the black bars on both sides. Watching 16:9 full screen HD wont cause issues with that. If only on the sides there is not much you can do except put a pure white screen on the TV and leave that on for at least 6 hours. This will age the panel a little but in theroy wil even the pixel burn you have to make the lines less noticable. Please take a few moments to rate my answer. Thank you

Screen is flashing different colors and no matter what I do, I can't get rid ot it. remote won't work, nor will menu button on top of tv. Now what?


You will need to have the Screen Control PCB replaced, however as a 27" TV it is most likely 3 or 4 years old.

It is unlikely to be cost effective to repair.

Sorry.

Samsung HD tv help


Is it a Plasma Television? I recently had a customer have the same issue with a 2 year old model Samsung 50" plasma TV. In his case one Of the computer panels failed. He didn't have a service plan and the warrenty was out, so i directed him to Samsungs help line. They inturn directed him to a authorized repair center. Repairs were roughly $800. Thats a possibility but it may not be the same as your issue. Try leaving your TV running for a little while when it has the issue, and see if it eventually goes away. Some older plasma models have started to require a warm up time for the pixel cells. This has been a down fall of plasma that for the most part no longer exists on newer models.
I hope eveything works out.

Have a great day
