If I shine a flashlight I just see what looks like a rainbow star

Hello

Thanks for the info, it seems either the backlight system of the TV has got an internal fault that made the screen dark OR the TV mainboard is faulty which controls the backlight switching

Customer: replied 22 days ago.
Ok so what can I do to fix it please

It needs to replace the mainboard of the TV that will either fix it or confirm the backlight LEDs are bad that requires taking apart the screen very carefully which is quite a complicated repair work

Please contact the local TV repair shop for mainboard replacement if the TV is out of warranty

I hope this info will help. If you have any additional questions, feel free to ask
Thanks for using JustAnswer
