Hantarex polo problem (SOLVED)

[Justez]

SOLVED: green colur IC transistor  faulty in socket board,

Hi.

I have a hantarex polo 25, the problem is that when I turn it on cold, for the first ten minutes I have green flashes and interference in the video, and a small buzz in the chassis.
After about ten minutes, it works correctly again.
I attach a video of the problem.

Hi

My best guess is that a cap is bad...
When did it last have had a cap kit?

Try to check the solder points at the neck board around the color transistors (try to swap the red and green color transistor, to rule out the transistor, if the problem follow the transistor)
Check also the cap C2

finally was green colour faulty transistor in socket board, thanx!!!
