Sony KV-27S22 SMPS question
Hello
I'm working on this set, which came in dead with one of the choppers shorted and C613 blown to bits. Surprisingly (well, maybe not) the main fuse is intact. I was also somewhat surprised that the power supply is a separate board. I replaced C613 and C614, both choppers, and R607 which is the fusible resistor right off the filter capacitors. R607 was replaced temporarily with a 1 ohm 2W power resistor to test the supply, which is working now. I'm trying to source a suitable replacement fusible resistor. Can someone please help me with the following information: 1.) What is the current capacity of R607 (0.1ohm is marked on it but no current rank) 2.) What voltage should C613 and C614's replacements be? TIA k |
