HomeSony DV32TW77 TV Set Dead Hello, I've got a Sony KV32TW77 and the set just died one night (no picture no audio). I've done some searching and I can say this much after taking the board module out. 1. Tested I/P voltage up to fuse = 120VAC 2. Tested I/P voltage for RY602 which should be 12VDC but found zero volts. 3. Lifted RY602 from board and supplied 12VDC and relay made contact, so it works. So I'm not getting the 12VDC req. to RY602 to get the req. 170VDC B+ Hummm...I'll keep looking....need some schematics and/or service manual or any trible knowledge to help me. TIA, Roy

I HAVE TH SAME SET WITH THE SAME PROBLEM. WHAT DIDI YO FIND THE FIX T BE? THANKS Actually my original post (first post) has wrong model number the correct model number is: KV32TW77 it's an 11 year old TV. Also, I'm pretty confident that the Power Supply is not working, even if I had the 12VDC to latch RY602 it still wouldn't work becuse there's no high volts being produced. Roy |
