At startup, synchronisation vertical as well as horizontal is very weak, after max. 15 minutes everything is ok. Sometimes there is no pictureFirst check all capacitors in the power supply. The real problem was spotted in the IF-area, the shielded space near the tuner: replace all capacitors there, especially the 2.2uF/100 volt type. I replaced it with a 3.3uF/100 volt type with excellent results!
