The TV powers up, shows the Vizio logo like normal. Then the picture goes black, but the backlight remains on.

When doing a factory reset, (Hold Vol Down + Input for 10 sec, release Vol Down and continue to hold Input). The TV will reboot multiple times, but nothing changes.

This has happened a few times since I got the TV, but always managed to snap out of it relatively quickly until now.

Been at this several weeks now. On my 3rd replacement Main Board.

First one showed the Vizio logo, then went black, but unlike the original, the backlight turned off.

Second was totally dead. Couldn't even get the logo to display.

Third board acted exactly like the original board. (Vizio logo, goes black, backlight stays on.)

Two replacement Power boards don't seem to have any effect.

A replacement T-Con board didn't seem to have any effect either.

I have not replaced the LED driver board, as the Flashlight test reveals nothing. And I know the panel is good, as the Vizio logo is displayed normally when the TV first boots. And yes, I did mix and match several of those boards before sending them back.

Do you have anything you can suggest? I have a multimeter, but I admit I'm not very familiar with checking voltages. Things like knowing what setting I should set the multimeter to, and what spots to check would be great to know. Pictures would be a bonus.

EDIT: I ended up buying a whole new set of boards (Power board, T-Con, LED Driver, and Main board) on ShopJimmy with zero luck. Same thing. Again, when it powers up, the logo comes up fine. Backlight too. So I'm sure the panel is fine. But I've literally replaced everything else, and I have NO IDEA what else it could be. There's no way I got that many dud boards. Please help!

EDIT 2: Tried reinstalling the firmware, but it never seems to get the point that it's reading the data off the USB drive.

I know nothing about circuts or anything but i do have a soldering iron so im willing to try. I could use some guidance on what im doing here though as this stuff is pretty alien to me

Below are pics of the power board, with a front and back of it as well as a close up of what I think are the capacitors for the backlight.

I have a Telefunken TV that's relatively new (less than 6 months old). Recently, the screen suddenly went black, and I can't see anything. Here are a few details:

• It's a simple LED TV, Model: 43" TLF D6
• I've left it on overnight a couple of times. Could that have caused damage?
• I did the flashlight test (shining a light on the screen), but I couldn't see anything.
• I've tried unplugging and plugging it back in a few times, but that didn't help. I also held the power button for more than 15 seconds three times in an attempt to factory reset it, though I'm unsure if that's the correct method.
• Normally, the Telefunken logo appears when I turn it on, but now I can't see that anymore.
• There's a difference between the black screen when it's off and when it's on: I can tell it's on because there's a 'light' or backlight, but the screen remains completely black with no image.

Thank you for reading, and any advice would be much appreciated!

It was still in warranty, so we just returned it to the seller, and they fixed it, I believe they changed part of the display, not sure which part sorry.

I recently bought a Hisense Google TV, everytime it gets turned off I have to do a power cycle if I want to use it. It'll play the sound for the show, but not the video.(The display/backlight is on, it'll just sit on a buffering screen when I try to watch anything) What do you think would be the cause? Every other tv/device in my house works fine, so I don't believe it's a network issue but I could be wrong.(I also don't think the tv it selected is the right one,
