    Re: Hitachi 55HTD52 Sound, but no picture

    Yes I did try with just the upper, but she still when into protect mode.

    That's part of the reason I wondered about the cause...

    I'ts hard to tell, but there may be a very minute cut or mark in the same ic on the lower board the had the screwy outputs.

        Yes, actually those are great in that they confirm the source of the bits and pieces of info I had so far, add some more info, and seem to lend support to or validate the trouble shooting path I/we've followed. The blown IC (buffer) fits it all perfectly now.

        Thank you!!

            TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
            by howardc64
            All left and right refers to looking from rear of TV (or looking from front with TV upside down)
            • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
            • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

            Problem

            This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

            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.

            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...

            LG 55NANO77SRA TV – Menu scrolling by itself even after removing button board (Main Board EBU66792103)
            by ygorsan
            Hi everyone,




            I’m looking for help with a persistent issue on an LG TV model 55NANO77SRA, which uses the main board EBU66792103 (also used in LG UQ80 and NANO75/NANO80 series).







            🧩 Problem Summary:
            • The TV keeps scrolling through the menu or selecting items by itself.
            • I removed the physical button board (the entire panel with power and volume buttons) and also disconnected the flat cable (CN202) from the main board.
            • The remote control is not in use (batteries removed), and the TV still shows the same behavior.
            • I

            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"...
