    There are 3 8-pin SMD ICs next to each HDMI port, get the P/N and look up the spec sheet.
    There is no pictures of the bottom side of the board to see what are mounted on the bottom side.

                  Check the data sheet to see if there is a ground pad under the chip or chipquick will do you no good.

                  I would use heat anyway.

                    Hot air work station and liquid flux, yes there is a metal plate on the bottom of the chip. A little chip quik will help for the pins only.

                      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...

                      (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....

                      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...

                      Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                      by Tynan Dill
                      I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                      Upon bringing it home and plugging it up, it showed a standby light.

                      I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                      The screen seems to blackout and stay black, but with a flashlight I can see the display.

                      With my Playstation 4 connected via HDMI, and running a game I can hear sound.
