    Samsung LN-S3251D HDMI failed

    Hi,

    I have a Samsung LN-S3251D whose HDMI ports failed. First HDMI 1 stopped recognizing inputs, but HDMI 2 worked. After a few weeks HDMI 2 failed as well.

    I took it to a local service shop, who say that the physical connectors are ok, so the only fix is to replace the main logic board. The board itself costs $250 from Samsung in Canada.

    I see however that there are boards available over the net from reasonable dealers for about $50, so I thought I might try to fix it myself.

    My question is whether there are differences between the various versions of the motherboard out there of which I should be aware. Also, if there are any standard gotchas in swapping out the board, that would be good to know as well.

    Finally, I'm wondering if there's any other cause of HDMI failure that the shop might have missed.

    For what it's worth, I have not had any of the standard issues with capacitors in the PSU on this TV

    Thanks in advance for your help,

    Nike

    The number one 'gotcha' is looking only at the price and ignoring the reputation (feedback rating) of the seller. There are many sellers that will sell untested boards, overcharging for shipping. If the buyer complains they are asked to return the board and a refund will be issued when the board is received. Since the shipping charges paid for the shipping, the eBay listing, and the seller's time, he's not out any money.

    It would be a very good idea to make sure the part number of the board you are buying matches the bad board, and the revision level is the same or higher.

    Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.

      This TV is 720p. Does the component inputs work? If yes, that should give you 720p without having to use the HDMI.

      Wow, $250? That is almost 50% of the cost of a new Samsung 50 inch 720p plasma that was on sale this last Saturday (sale price was $548 CDN).

        Actually, Samsung wanted $250 for the part, and $100 on top for labour. It's crazy.

        Where was the 50in TV you mention was on sale? It seems like the 32 inch TVs have all been around $450 for a long time now.

        I am probably just going to replace the TV, and fool around with the board for fun if I can find one cheap.

        Cheers,

        Nike

          If 50 inch is too big, 42 inch LG/Samsung plasmas are now regularly $500.

          IF you manage to find a replacement board for $50 total, then it might be worth trying.

            The space is small, so a 32 is the biggest size I could use. However, prices on those are not really dropping.

            Does anybody here know where I can find reasonable data on brand reliability?

            Thanks in advance.

              This forum is more for fixing things. If they are not repair related, then I will direct you to

              redflagdeals.com

              for Canadians. If you take some time to look through it, you will find deals like

              http://forums.redflagdeals.com/warm-...pmd-fs-940515/

              for $313.

              Ask "deals" questions over there and let's end this thread unless you have more repair related questions.

                Samsung Power Supply Board BN44-00874F
                by Nicktronic
                Hey everyone,

                This power supply board is hard to find but there are repair kits available. This board had a blown fuse, FP801S, blown PFC MOSFET, QP802CS and ceramic cap, CP809. I replaced them with parts I already had and tested the rest of the parts that would've come in the repair kit and they were fine. I powered the board up on the bench expecting, in typical Samsung power supply board fashion, to see all my output voltages but, nothing. 0 volts on CNL801, CNM801 and CNT801. The only thing I have is 170vdc on the filter caps. No standby voltage either.

                Anybody...

                Help Needed: Samsung UE55MU8000 Dead - Possible Main Board Issue
                by Asraf Atb
                Hi everyone,

                Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.

                Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.

                I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue....

                Samsung UN65KU6290F PS board blows fuses
                by valvashon
                Samsung UN65KU6290F (May 2017); received from local Buy Nothing group. Was listed as "just went dead" and they wanted it gone. I brought it home, didn't notice anything visually wrong with the power supply board, looked up the cost of a new one and that's about as far as it went. Family was tired of tripping on the foot of the set so I decided to dig in and repair or toss.

                Can't believe that I didn't check it earlier but I found the main 8 amp fuse blown. Jumped across it with a 10 amp blade style fuse and you can see that it literally exploded inside the second I plugged...
