Sony KV-32HS500 H-Stat Drifts
Make : Sony
Model : KV-32HS500 Problem : About a year ago we went to a customers house to fix this set for a mis-aligned H-STAT adjustment. Customer had the set for about a year at that point and they noticed the picture gradually got blurry/misconverged over time. By tweaking the H-Stat we were able to get things back in spec but the adjustment we did required the pot to be at a fully extended setting. Just got a call yesterday saying it was out whack again ( 1 year later!). Some techs had pointed to bad CRTs on these sets........just wanted to poll the masses again to see if anyone has experienced otherwise for this problem. I suppose the only was to rule out the CRT would be to try the chassis on another set. Unfortunately we don't have another at our disposal to do so ( At least not today!) ========================== Jeff Stielau Shoreline Electronics Repair 344 East Main Street Clinton,CT 06413 860-399-1861 860-664-3535 (fax) ======================== |
