Sony TV model KV27S46 Shorted Hor. out.
Set came in with "just clicks" complaint. Customer says that it had
been cutting off after about 15 minutes for a while until it went out for good. The hor. output a 2SC5426 is shorted . I planned to go over the soldering however I was advised by another tech. that I should also look for a bad cap (he wasn't sure if it was an electrolytic or perhaps a mylar) in the supply circuit as well. Does anyone know if there is any further information on this set? Thanks, Lenny Stein, Barlen Electronics. |

Cap mab be the located in collector ckt of driver, near h-drive xfrm. wrote in message ups.com... Set came in with "just clicks" complaint.
