I'm asking this question for a friend who has a sony RPTV which has gone on the blink. It is a 42" crt rptv which must be about 8 or 9 years old.(model no KP-54112u). It looks like one of the picture tubes is knackered. He is having problems getting anyone interested to diagnose and possibly fix the thing, which seems a shame as it a lovely set. One engineer wants £250 just to come and have a look at the set! Can anyone offer any sugestions where to go from here? TIA, Beo.
