This set was repaired about 9 months ago by another shop.They replaced
both of the STK-392-020. Now 9 mo.later it has the same problem.I
checked all the small ohm resistors and they are ok.I think that they
might of used generic type ic's or maybe the vcc to this chips is not
correct.The red is way off.Before I replace the ic's again,can someone
tell me what the vcc to the ic's should be,i.e. +26v and -26v) or +16
and -16v.Is sony having any problems with their yokes that might be
causing this.I am all ears for suggestions and or tips. Thanks
