I do not understand what you mean are you referring to draining the TV or the box?

Expert:  Anthony_Infotech replied 11 months ago.

Do you mean rebooting?unplugging from wallpower?

Customer: replied 11 months ago.
I unplug the tv from the wall and push the power button for 30 secons. Than I have been able to trun one the tv normally for a day or 3. Than I have to do it all over again. Now I have no picture and the message on the screen reads not supported...
Expert:  Anthony_Infotech replied 11 months ago.

OK I see it looks like the software that controls the mainboard is bad you may need that board replacing do you think you can do that work yourself?I will provide all the necessary info for that

I unplugged the Charter cable box for 1 minute and now the TV works fine. No I can't replace the board. I think I am all done here.
Expert:  Anthony_Infotech replied 11 months ago.

Ahhh I thought you had done that that is why I was confused with your reply yes the signal went because the box is bad rebooting usually solves this

Many thanks
