Vertical Hold Problem - Sanyo - Cold Solder Joints ?
When DK stomps , the sound of the thump , and when I tap the cab , it causes the monitor to loose Vertical Sync . When the sound is off it doesn't loose sync . Seems like maybe cold solder joints somewhere , where would you look ? Any specific areas ?
I've replaced :
Vertical Hold pot on monitor and adjustment pot VR2 on the DK PCB
Capped the monitor and replaced tr402 and tr403 .
replaced D161
reflowed solder to IC401
