Hi .check the smd capacitors on the main

Good Morning:
I still have the same problem, I bought a board on ebay used and does exactly the same, ie if you turn on when it is cold it makes noise in the speakers and presents vertical scratches on the screen, after a few seconds it works well.
If it goes off after 15 minutes, it shows the same symptoms.
What to do?


Thank you

Carlos
