Thomson 65UD6336 black screen

Hello.

I have a Thomson 65UD6336 that has a problem. The television is only two and a half years old (2-year warranty not applicable) but I would still like to try to repair the equipment.

Basically, the screen "turns on" (power supply etc. is okay) but I see that it remains under a relief of blacks. Let me explain, at startup, I can see the THOMSON in black on a black background if I look from the side, and once connected to the box, I can also see the menu etc., but all in shades of black on black... as if there is no color. I think it might not be too difficult to repair, but I'm relying on you.

I have opened the back cover but I'm stuck on which component to check, and how...

Or if it's a board that needs to be replaced, but which one? I have one on the power supply in yellow, a green one where I have the HDMI, sound connections, etc., and a very small one that connects what I think is the screen...

Thank you in advance, I hope to be able to save it!

Michel.

    Hello Shinoda30,
    I think it's an LCD TV, right?
    And considering what you're saying, I also think that the backlight of your screen is "dead" or inactive.
    At home, there’s nothing you can do except have it repaired by a technician!
    Best regards!

    Okay, thank you for your response.

    Even replacing one of the circuit boards wouldn't change anything?

      Well, do you know the card that's causing the problem? No! So have a technician take a look at it and let you know how much it might cost!

    This problem is the same as mine. The issue isn't the board; I even bought a new power board but the same problem occurred after testing it and noticing that the backlighting needs to be changed.

    I keep mine at home until I get new backlighting.

    Same television and same size TCL 65ud6336.
