I have an LG 70UN7070PUA, 4k television I'm having a problem with. It's hard to explain but I'm getting these red pixel smears on the screen. They movie around when something on the screen moves. I replaced the TCon board but it's still doing the same thing. It does this on all 3 hdmi ports and no matter what hdmi cables I use. Should I try replacing the main board next, or is something else the problem? Any help would be appreciated.

What's strange is that after several minutes, the picture will start to resolve properly, starting at the top and working its way down. During this time, there are no issues with audio and the menus are responsive to input with no freezing or delay. Below are some pictures taken specific timeframes after the TV has been turned on (put into Store Mode to demonstrate).

Just after turning on:

After about 2 minutes

After about 5 minutes

After about 7 minutes

After about 10 minutes

I have tried replacing the T-Con board and the ribbon cables between it and the display, but the issue remained the same after doing this. Same with reseating the LDVS connectors to the main board.

I'm trying to figure out if I need to replace the main board now, however after being burned on a T-con replacement that I apparently didn't need, I thought I would ask if anyone has seen anything like this before and could advise if it might be from some other, environmental issue or an issue with the screen itself. I've tried running it on and off the surge protector, on a different outlet in the room, and even with the nearby router turned off in case there was EM interference.

My TV suddenly started displaying vertical colored lines across the entire screen, mostly white and black. There is no visible crack, impact mark, or external damage to the panel. The TV was working normally before the issue appeared.

TV powers on normally.

The backlight appears to be working.

The entire screen is covered with vertical lines and distorted colors.

No visible physical damage to the screen.

The issue appeared suddenly during normal use.

Power cycling the TV did not resolve the problem.

All cables and external devices have been checked and disconnected.

"The 120V AC outlets on my Goal Zero Yeti 1500X have stopped providing power. When I press the AC button, the LED turns solid white and the unit emits two loud beeps, but my digital multimeter confirms 0V at both outlets.

Troubleshooting already performed:

• Soft reset, Factory reset, and Deep Battery reset (RESET+INFO).
• Tested with all inputs/outputs disconnected (no ground loop or overload).
• USB and 12V DC ports are still working; unit still accepts a charge.
• No 'Exxx' error codes or temperature icons appear on the display.

Since the AC light turns white but no power is output, I suspect a blown internal inverter fuse or a failed MOSFET. Does anyone have a board diagram or know the specific locations of the internal AC fuses for the 1500X?"

After looking into replacement options, I found that replacement touch panels are difficult to source. Since I rarely use the touch controls and mostly rely on "Hey Siri", I decided to try disconnecting the touch interface instead.

Using a teardown as a reference, I found that disassembly is relatively straightforward and the touch panel connector is accessible without too much difficulty.

I did not document the full process, but if you follow a teardown, the general steps are:

• The base is held on with strong adhesive, so you will need to carefully pry it off
• Remove a couple of T6 screws and one T8 screw
• There are a few additional T6 screws securing the internal assembly
• Once inside, locate the ribbon cable for the touch panel, which uses a small lever latch connector
• Disconnect that cable, then reassemble everything

Note:

If replacement touch panels become available, you can replace the touch sensor at this stage instead of disconnecting it, since the connector is already accessible during disassembly.

Result:

You can disconnect the touch panel, reassemble the HomePod, and it will continue to function normally. The only thing that no longer works is the touch input.

I wanted to share this because I had not seen many people suggest simply disconnecting the touch sensor as a workaround. If your HomePod is experiencing ghost touches or random playback, this can be an effective way to keep it usable without replacing parts.

Since most smart speakers are primarily used via voice, losing touch functionality is not a major downside, at least in my case.

Be careful when removing the base adhesive and disconnecting ribbon cables to avoid damage.

Hope this helps others!
