Re: IQ SMART TV 22" weird problem

You can try heating/cooling different areas of mainboard to see if it makes a difference.

You mean with power on or witout?
How can I heat it locally? I have hot air station but I can heat it while it is on place because it will destroy the screen and if I remove it it will cool before I turn it on

With power on you can heat or freeze to see if it will come on.

Nothing, it just working for now. If I use it this way one day it will just stop working again for one-two days (sometimes more) and then starts working again
