I have TCL Roku 55s403. It is 2 weeks that when I turn it on I get a blue screen. I have tried a lot of ways like reset factory, unplug for 30 sec and reboot the TV. they used to work but 3 days ago the blue screen persistent and I could not turn on the TV for 2 days. yesterday I just turn it on and after 5 min the picture shows up and was working whole the day but when I turned it off the problem was back and I still can not see the picture
I am wondering if it is a hardware issue? what component In the mainboard might have a problem?
