Hi everyone,
Iām 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).
š§© 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.

TV was fixed just after removing Samsung's rear snap cover.
This curved TV's construction is rather interesting. When the snapped on back is removed, rest of the TV will relax the curvature. Top of LCD panel is loose as it wants to straighten out against the slightly curved bezel. Snapped back provide most of the curvature shape. So just simple disassembly of rear cover will allow the rest of the TV frame to relax its curvature. Thats probably what fixed it but no idea which connection. 4x LEDs are edge lit.

Hi all, I have a Dell Latitude 7300 with a locked BIOS and I was curious about the process of removing the lock by editing the hex values of the bin and how to do it. Is editing the hex values of the dumped bios any different than flashing a new one that's already been unlocked? (I currently don't have the correct bin because I realize I accidentally dumped the wrong thing). I am very new to this any help or advice or references would be greatly appreciated. Thanks

I got this set for very cheap, it works perfectly but the catch is that the protective coating was damaged. About 45% of the screen had a green tint, you can see exactly where the layer changed colors to a blueish tone (that actually makes everything green).
"Ok, that's probably just the anti-glare layer" - I thought. So using a microfiber cloth and automotive metal polish I was easily able to turn it into a nice mirror.
Unfortunately, the damage was beyond this layer and everything still had a horrible green tint. I initially... -
Hello everyone,
About me, my goal and the equipment I (don't) have:
I am brand new to this forum, and I am eager to learn about repairing laptops. I have an engineer background although I haven't done electronics for a while. I have watched several Youtube videos in the last two months, trying to understand how to diagnose a faulty motherboard. I have a USB-C Amp meter and a classic multi meter. No DC Power Supply to inject voltage, no soldering iron to replace components.
About my issue and my goal:
A friend of mine has a MacBook Air M1 A2337 that does not...
