Fixing TV blue tint

This is my first post on this board so I hope it’s ok to ask here.

I was given a TV for free because they wanted to throw it away. The issue is that the screen has a blueish tint like pic related. I want to dedicate my weekend to try and fix it myself. But I do not know what the issue with it is or how it can be fixed.

Help please.

    Put it back in the trash. Only panasonic plasma tvs are worth fixing

    you cant fix that unless you replace the power board or possible the driver board. at that point its cheaper to just buy a new one. buying the replacement parts on their own+shipping arent worth it especially to take it apart and swap parts only to cost you more than a new cheap tv from walmart

    You'll have to disassemble the TV. Most likely the motherboard is bad. Thankfully you can buy and replace these parts easily as there are a ton of TV breakers who sell these parts on eBay and other stores. The only critical part is the LCD which if you break makes the TV trash.

    Too many possibilities, and you are not giving us enough information to begin with. Fixing this would require /us/ more energy than the TV is worth.

    It's the main board that's bad.
    It has the picture processing part the power board led driver are all fine since the panel lights up and powers on

      not necessarily.. it could be delivering the improper voltage to the display board... theres several factors that could cause these issues.

    >blue tint
    Have you checked the other inputs? What input type are you using? Did you factory reset all the settings?

      This, factory reset might solve the problem. Also before you go poking around make sure you know how to recognise the main power board and avoid it. It's not nearly as bad as an old CRT but if you touch the wrong thing you could get a shock from energised capacitors

        What I'm saying is OP is not giving us enough information. He might be using VGA with a defective cable for what it's worth.

        The backlight is fricked. The repair is extremely difficult and honestly not worth doing for a tv that is eh
        But if you really want to go for it:
        You need to disassemble the tv entirely

        Pull the panel - you will probably frick this up. Large flatscreen tv panels are amazingly fragile and merely lifting them up incorrectly will crack them.

        Once the panel is out and the back light is exposed inject power into the back light. Don’t look directly at it, it’s bright as frick. You’ll see some of the LEDs are blue. These are fricked. You’ll need to pull the strips with these out and source suitable replacements from somewhere. Replace them, close the tv. Good to go

        It sounds easy but I can assure you it is not. Again, pulling the panel to get to the backlight without breaking it is astoundingly difficult. And beware of very high voltages and current going to the backlight, if you die it’s not my fault.

        This happens because tv manufacturers cheap the frick out on driver circuits for backlights. After a few years of operation (and sometimes sooner) there will often be a voltage spike that blows up some of the LEDs and either kills them or leaves them stuck in a certain color. If you do this repair you’ll see this; you can pry the lenses off of the afflicted LEDs and will see a portion of them has often literally blown apart.

          I think the backlight is fine. I see lots of blue and a little bit of red. This suggests that there is no green drive to the screen. Can't say whether it's a cable or a board problem at this point.

            hard to say with just a single image, but I’ve seen similar display happen on vizios because the backlights end up overdriven, one or two of the channels blow out on several of the leds, then they stay stuck on in whatever channel remains (in this case blue) so the picture stays tinted blue. It could absolutely be a driver issue too though, hard to definitively say from a single shitty picture with no real description I guess

          I would say open the TV case. Do a visual and smell inspection. Trash it if nothing evident.

    um. have you checked in the picture settings for "RGB mode". it could be set to "Blue". factory reset to be sure. you can try flashing the software. good news is this isn't related to the screen itself, which cost the most to fix. it's likely a bad chip somewhere. having it fixed by a professional / company technicians may not cost you much.
