    Can you clean up the damage area with some isopropyl alcohol - you may even be able to read the part number on the burnt item

            OK No - I think it is I301
            I searched for the board number.
            The same board is in the G245H.

            See Attached

            Think it is one of these

                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...

                by m1ch43lzm
                Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
                Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

                Is it possible to upgrade from a Vestel 17MB97 main board to a 17MB110 Main board?
                by cheeky2
                I suppose the real question is whether the existing pinouts from ether a 17IPS71 psu are cross compatible with a 17IPS12 psu? If they are then the exchange of the main boards should have no issues providing the screen is compatible with both main boards. Obviously you can change the screen configurations easily enough (providing you have the correct files) for the main board. Why may you ask would I do this? Well a lot of the smart features are no longer working on a Hitachi 48HBT62U main board I wish to give it a new lease of life!
                Obviously the same LVDS connector for the screen connection...

                Driving a Sharp TCON/panel with a universal main board
                by advant
                This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.

                I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match...

                [HELP] Acer AN515-55 (LA-J871P Rev: 1B) – Board won't power on after GPU investigation – Suspecting Super I/O or PCH

                Hi everyone,

                I'm working on an Acer Nitro 5 unit with the following specs:
                • Motherboard: LA-J871P Rev: 1B
                • Model: Acer AN515-55-59MT
                • S/N: NHQ7JAL00403906A973400
                • SNID: 03902728734

                Initial Issue


                The laptop initially presented graphic issues and driver failure (Code 43) for the GPU.

                After preventive maintenance (cleaning, thermal paste, etc.), it powered on normally. We disassembled it again to inspect the GPU, reassembled...
