when the TV is turned on, it works well for approx. 15 to 20min, then the screen starts to fail first, the colors change, then the image starts to shine bright as if it had a lot of brightness, the source voltages are correct, also those of the main card. is that the main chip of the main card is heated up to 62 degrees centigrade. I measured it with a temperature sensor when the TV the chip is cold the image is normal but when it reaches 62 degrees there the screen begins to fail with the faults mentioned before.

Hello colleague ... how strange I thought that only the color and brightness faults were caused by the ic video chip of the t-com .... do you talk about the main's microprocessor? Is it the one that heats? .... check if he uses heatsink friend ...

if it has a heatsink but even the heatsink and the chip overheats or it is cold while the image looks perfect but when the temperature of this reaches 60 degrees the colors change and lines appear brighter every time even if I give it a few taps it changes and it makes other flaws in the image if I turn it off and let it cool it looks good again

Ps friend is about how you can put a power fanncooler ... see if it improves .. I would think that at the moment you use that option ... and the other would be to change that card since how many micro failures in the main are almost unreparable ... greetings
