Question about Sony FD Trinitron WEGA KV-34HS420 34" TV
How could i fix the problem with my tv. it flashes 7 times then turns back off
Most likely there is a failure in the power supply or in the scan amp sections. This will require factory level troubleshooting to determine where the faults are.
This type of service may be on the expensive side.

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.
