    Samsung Main board swap problem. incorrect Resolution.

    Hi I have a samsung 1080p 37inch TV that I've swapped the main board out on (after the bad caps had been replaced on the PSU board).
    When I've installed the new board it is detected by my Mac Mini through HDMI as a 1366 x 768 display instead of a 1080p display.
    I don't have a remote with me to jump into the settings but am wondering if there is anything in the engineering menu to set the resolution of the panel that the board is plugged into?
    The TCon board was fine before the mod but the power kept turning off on the board (tried changing the rom) and it seemed easy just to swap the main board over.

    The image does not correctly fit the screen and the lighter colours on the panel are incorrect. The image seens to get to about 768 pels then there is a blank and the image starts again off the bottom of the display.

    To add insult to injury the new board I bought from ebay is rusty down the HDMI and VGA connectors. The board has definitely seen some water damage but was sold as from a working set. I assume though that the fault I'm seeing is not due to the water damage.

    I believe there is a setting in the Service Menu to do what you're after. Someone with more direct knowledge will chime in shortly I'm sure.

    I do think any remote will do - any Samsung or Universal since the key strokes are common ones. Good luck.

      Usually you can change the display settings to 1080p from the settings on your mac.

        The problem isn't so much with the mac being at the wrong resolution it's that the TV is detected as a 1366 x 768 resolution (the main board is using the wrong panel resolution). Hopefully there's a setting in the service menu that will let me change it. Just need to fish out my remote control now.

          Yes, there often is, but not always. If your TV is fairly new, it may not work; but older Samsung it is definitely possible.

            We are seeing more and more board fails on here due to hdmi.
            I would now advise switching a set off (unplug) then plug in or unplug the hdmi.
            Doesnt seem any sort pf protection - direct connection to the main processor.

              Hi everyone. I managed to get the service menu up.
              I changed the following:
              Inch option to 37"
              Panel type to 37"AU FHD
              Changed high Devi to on.
              Nothing that I can see will up the resolution. Is there a particular setting I need to look for?

                It may be that the main board resolution cannot be changed, sorry.

                    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....

                    Sceptre U550CV-UMR 4K LED, Bad Caps on Main Power Board?
                    by Dani_2024
                    Hi and thanks in advance for any input you might provide!
                    I have a Sceptre U550CV-UMRD8POTV83BB 4K LED (this is a dumb tv) that I bought new in August 2021, so It's just completed 3 years.
                    Main power board model: TP.MS3683.PC821 T-Con board: N4TP546UHDPU2L_BO

                    Last Sunday I was watching a dvd and fell asleep for about half hour, when I awoke the tv screen was black and couldn't get the dvd menu to show, so I changed the input to antenna and had sound but no picture, turned it off. I then got online and found this great site! ....read many troubleshooting tips and this...

                    Samsung UN75RU8000FXZA bad main board?
                    by Lee M.
                    When plugged in it will click and cycle the BL on and off, no pic and does not respond to remote. When I disconnect the cable from the PS board to the main board and then plug it in the BL will come on and stay on. There are only two boards in this set, the LVDS cables from the panel driver boards connect directly to the main board. Since the BL comes on and stays on I'm thinking the PS board is ok and the problem is on the main board. Should I order another main board or do I need to do more testing? thanks, Lee

                    Sony xbr-65x900c main board issues?
                    by jb_Bak
                    Hey guys great forum glad to have found it. I bought a Sony XBR 65X900C cheaply because it didn't work. No signs of life at all not even a light/led. All I hear is a brief high voltage sound when I throw the power to it.

                    Didn't see any obvious signs of damage so right away started checking voltages. This is what I see:
                    Power Board Connector that goes to Main board
                    CN6401
                    Pin 01 NC
                    Pin 02 NC
                    Pin 03 "BL_ON": 0V
                    Pin 04 "N/C"
                    Pin 05 "STBY 3.3V": 3.5V
                    Pin 06 "GND": N/C
                    Pin 07 "AC_OFF"...

                    (SOLVED) - ONN 100012588 No Power, Then Rebooting After Main Board Change

                    Issue: No Power, Then Rebooting After Main Board Change

                    Short answer: replace main board and power board
                    Technical answer: replace main board and Q306 & Q307 on power board.

                    Long answer:

                    TV wouldn't turn on. Power switch was fine which means the main board isn't processing the power on signal. Replaced main board. TV turns on now but randomly reboots. Bad main board? EEPROM? Tried to pull main board and got a shock touching the corner of the board. That's weird. C334 (450V 10uf) capacitor is still holding a high charge....
