Thank you very much, friend Tobias for your information and help, but as I told you in the initial question I tried the TV with another T COM Card from another operating TV and the result was the same, now before doing that test I had tried to keep it refrigerated with a coler fan and the result was also the same !!! The fault is clearly on the LCD panel or display! If you can give me some tips on how to try to save the panel I would appreciate it
to see, it occurs to me that it can be the flexes that have false contacts, those that go from the panel of the panel to the flex, notice this video from minute 9.30 onwards
