sounds like a dry joint ,
and only when the set has warmed up the joint expands and then makes electrical contact try looking around the audio stages , or if you don't know where that is try all over to find a dull or cracked joint you may need a good strong light , and a mag glass also wiggle component to see an movement on the soldered side if this can be seen then suspect that .. cheers |
