Re: Le32a553 Button Board Failure Help ?
I would check the resistance between the terminals of the switches to see if it shows leakage resistance.Never stop learning

Re: Le32a553 Button Board Failure Help ?
I fixed the Tv by replacing the button board for £5 as the buttons were 99p each so not worth it. New board in and all working

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

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?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.

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.

Hi.
Long shot but does anyone have a schematic & boardview for the audio board+power button on a Macbook A2179?
There is a shorted cap on mine and I need to know if I can safely remove it or whether I need to replace it and with what capacitor.
Many thanks. ...08-21-2025, 02:38 PM -
the board (yes, just the motherboard & daughter board) came to my desk with shorted ITE8585E, after ordered a programmed ITE and placing it on motherboard it turned on immediately, using HDMI i confirm that the boot entering the bios since there is no bootable drive attached. then i turned off by unplugging the DC adapter, while preparing keyboard, mouse & some flashdrive to boot into.
after all plugged (including adapter) the board doesn't "auto turn on" like before, pressing power button with no change. without unplugging anything i'm checking voltages needed...
