Chosen Solution

I start playing with picture and sound, after 2-4 minutes of playing the picture starts to get lines and then it lost. I still get sound. My TV reminds me to connect the cable. I have stored it for 3 years. When I got it out it was ok as I played for a few hours.

friend unfortunate this with apparent error in the chipset as it is an old console there may be a lot of oxidation

try to clean it, open and check the components and inputs
