TCL 49S405 has sound but no picture (bluish backlight)

Jump to solution

My barely passed 2 years old TCL 49S405 is probably dead. When turn on, it has sound but the screen has this bluish backlight. The control seems to work and making click sounds but no picture. I ordered the repair kit and replaced the power board, TCon board but didn't help. Still the same blueish screen upon starting up. Searching google it seems like quite a lot of people has this issues and while some replaced the TCOn board and it worked but for some that didn't help. Anyone has the same issue?

I have 3 of these same Tvs in the house and probably the last TCL I'll buy.

Thanks for the post.

Have you tried contacting TCL support yet to inquire further? I'd suggest starting there to see what options or suggestions they can provide. Each Roku TV manufacturer provides direct support for their products running the Roku OS. 

You can reach them here: https://support.tclusa.com/televisions or at 1-877-300-8837.


Thanks,
