Question about Sony FD Trinitron WEGA KV-34HS420 34" TV
The problem is in the standby power section. Check the fuse, R607, or burnt IC601, fuse R612 and VD relay 601 should show open. Its possible it could be the high voltage area of the power supply. You can try unplugging the set and cable and let it sit 4 to 6 hours. This is a hard reset. If it still doesn't turn on after the hard reset and the fuses and relays are fine, and you don't smell anything or see anything burnt. Then you'll need to call a TV repair man. They normal start around $150-$200 to fix the set. I hope this helps.

Thank you for your question.
Fortunately this is a common symptom and there is a fix for it.
There are two power supply IC's and a capacitor that need to be change. In particular IC6501, IC8002, part number, Mcz3001db, and C6556, 33uF @ 160V.
