    Hi guys- I am having an issue with a 46 In Samsung LN46B650 with vertical yellow and red lines and ghosting as well.  A little research reveals lots of problems with this issue and it points to possibly or more likely the T-Con board ? would you agree with this assesment and also I have read that this model is much harder to access than in the video above.?
    Thanks
    Randy

    Hi Shop Jimmy, 

    Great video!  My Sanyo was experiencing some common vertical lines and I replaced the T Con Board.  The TV was working fine for about 5-6 days after the repair, but the problem is back.  The lines appear sporadically for brief moments of time.  Is this an inherent problem with the ribbon connections perhaps?  Can I tape them or something to make them more firm? Thanks again.

    SAMSUNG SMART 3D TV MODEL No: UE46D6510WKXXU
    AFTER PERFECT PICTURE FOR 2 YEARS, WITHIN 24 HOURS OF GETTING BLURRY PICTURE TO HAVING NO PICTURE, ONLY SOUND. 

    THE TV HAS NEVER BEEN MOVED HENCE NO EXTERNAL FORCES COULD HAVE DAMAGED IT.

    ANY IDEAS JIMMY?

    Hi, my samsung tv is solarized. if i let it "rest" for about an hour or so and turn it on, it's fine again, but only for like 15-30 seconds tops, then it gets solarized again over the course of a minute or so. i've opened the back panel, didn't see anything unusual on any of the boards. disconnected and reconnected all of the cables on the t-con, didn't make any difference… any thoughts of whether or not i should buy a new t-con and replace it?
    Thanks in advance!

    How do I replace the LED panel on my Samsung UN40D6000SFXZA Smart 40 inch TV? How much does the replacement panel cost?

    What is the extra port on the T-Con board.

  13. Parminder Sahota says:

    I have a Samsung 46 in 3D LED TV. We get audio on it but the video stopped working. It does have the back light still. I watched a few of your tutorial videos on YouTube and think it has a faulty TCon board. The part for that is LJ94-03870c. Do you think it is the TCon board that I should replace. Do you have that part? How do I replace it because one of the ribbon is difficult to remove?

    Hello. Sorry for the late response. I performed the flashlight test on my 46" Samsung LED TV and found that it does have the backlight and audio. Please let me know the pricing and availability of the TCon board. Thank you.

    Hi, I have a Samsung 32 inch lcd tv. Model LN32A330J1DXZA SERIAL # AKZ43CRQ800919Z. TV has no power or picture. The capacitors look good, no buldging or leaking, could the t con board also cause this problem? Right now the tv dose nothing, Thanks for your time.

  24. Daniel Duarte says:

    Question, I have a proscan LCD that as soon as any picture shows up the tv automatically shuts down. It does this as soon as a picture from the antenna, dvd or xbox comes on the tv. I have disconnected various boards and what I have discovered is that when I disconnect the FPC cable from the T-Con the tv stays on. There are two FPC cables and I have tried leaving one connected but as long as any FPC cables are connected the tv automatically shuts down the moment a picture signal reaches the tv. I can work the tv menu on the tv as long as there is no signal input. Does this mean the T-Con board is junk or could there be other possibilities?
