spanish Zenith System 3

[tritwi]

It also losses the tint control useless for pal. I also have a similar 13 inch system 3. This is original from USA but the picture is not very good. the black level is too much low and parts that should be black are light grey. It also shows retrace lines. I should open it and adjust the G2 but i suspect there are cold joints. the picture also flickers especially on a side but it could be the different mains frequency.
