Lg smart tv: Red Pixels On Screen

Fri, 17 Jul 2026 14:16:42 -0700

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.

Samsung Television: Samsung TV red standby light blinks twice, TV stuck in boot loop

Thu, 16 Jul 2026 15:45:44 -0700

TV model # UN75NU8000F turned off while watching Netflix and began a continuous boot loop. You can hear an audible click as the TV attempts to power on and the screen briefly lights up with a light blue hue - standby red light blinks twice before TV starts the process again and continues until unplugged. Have tried all steps to troubleshoot besides replacing internal components/boards. Samsung technical care has informed me that two blinking lights is code that the LCD panel has gone bad and needs replaced despite me telling them I can visually see it light up for a second before the boot loop continues.

Pictures of boards attached, dont see any capacitors that are apparent issues and need replaced, looking for some advice.

Hisense Television: Short to ground on mainboard

Wed, 15 Jul 2026 18:14:08 -0700

Hi, I have a Hisense TV that won't come out of standby. (Hisense Model-43A7100FTUK). It has an issue where it won't come out of standby. I get a flashing led(2 flashes)(well 1 definite flash and a quick flash so assuming 2)2 flashes from research means problem with main board. I have poked around the board for a couple of days now trying to find anything that may indicate a fault. No obvious signs of stress or overheating. What I have found is a coil/inductor (L0002 on the board)has a short to ground. I removed the coil and isolated the short. One of the sides of the coil goes to a diode and mosfet. The mosfet seems OK and not shorted. The short is on the other side which goes nowhere other than into the board and off on a journey somewhere else. I can't find a short anywhere else, have tried injection but hitting CC so voltage at a minimum and no heat. There is a chip amongst those inductors that I cannot ID (2510S). Cannot find any informationon that. The other number is 210106 which seems to manufacture date. Any help would be massively appreciated. Many thanks in advance.

Mark

I have a SAMSUNG UN43TU7000FXZA. The screen is black and if I shine a flash light at it I can see a faint image of what should be displayed. I assume the LED strip needs to be replaced but I am not sure. Any help is appreciated. Any tests I can do and is this a common failure?

Insignia NS-50D510NA19: TV screen wavy pattern after LED repair - Optic stack not digital

Mon, 13 Jul 2026 05:07:51 -0700

I did a backlight repair on an insignia 50" Amazon fireTV. I have a problem when I do these repairs. I'm terrible about keeping the optic stack in order and I don't do tv's all the time so the order that they're generally supposed to be in doesn't stick with me. But that's more of a side note as I'm pretty sure it is correct as I verified with AI. But still it is an optic stack problem not a digital problem. The picture is pretty clear but wavy patterns (presumably from the prism films) are visible and it distorts more as you move around and change the viewing angle. This can also create dark/shaded areas. So ya I asked AI to verify the order of these films and I have it as so. Starting from the rear most (closest to backlight) is the thick plastic (LGP), then the white film (diffuser), then two prisms, then lcd panel support bezel, then of coarse the lcd itself. The orientation of the films (top/bottom, front/back) can't be flipped as notches and dowels only allow them to go in one way. I tried swapping the two prism films with each other but that didn't help. AI tells me that it's because the films are warped and aren't sitting flat. Any advice on that?

Sony Television: Back Panel Removal on a Sony XBR65X800h

Mon, 13 Jul 2026 01:37:04 -0700

This is a unique set in regards to the back panel. It is a full rear panel, top to bottom. Minimal screws on the bottom and none on the top similar to Samsung’s screwless back panel. How does this come off? Does it pry off like the Samsung TV’s? To be clear this is not the half back panel that the slim Sony’s have. This is a full back panel. Unique to this size of tv. The image above is the actual set.

I removed 5 screws. 4 where the wall mount would screw into the set and one by the power plug.

Looks like the bottom is held in with plastic clips which I have released. The sides and top all seem to fit into the front frame all the way around so no way of hitting the bottom to have it slide up. Maybe the front frame has to come off first? The rear panel is connected to the front panel frame.

When I turn on power the vizio logo flashes for a few seconds, then is steady, then goes off and after a few seconds starts that cycle again. It does this over and over with me not touching anything. Screen remains black.

Hisense Television: Screen Flickers with Horizontal and Vertical Lines

Fri, 10 Jul 2026 08:41:09 -0700

We bought a new TV back in December to replace this one, and until recently this TV was sitting unplugged in a hallway. After moving it upstairs and into its current location, the screen starts covered in horizontal and vertical lines, bleeding the colours on the screen. This occurs on every input and in the menus.

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.
