I have a 13 year old RCA projection TV model # P46159HK. Last year it wouldn't power up and the repairman said that the fuse was blown. Rather than replace the fuse, he took the unit to the shop for a diagnostic. It came back with a $280. bill which read " GMA 5 fuse, 1,8v2 15w resistor, 61-145 P.S. kit, replaced defective components in power supply circuit". The tv worked fine for months but has now powered off again. I don't really want to invest more money but would like to take a shot at replacing the fuse. Is the fuse readily accesible and if so where do I find it? Thanks.
