Never worked on one but a few notes.
Sony often uses very low ohm resistors as fuses. On
most of there sets a shorted hoz out will take the
power supply with it.
Typical is either a cold joint in hoz drive or bad FBT shorts
the hoz out & it shorts the 2 converter transistors & opens the
fusable resistor.
Working on it shouldnt be to physically hard. Sonys usually
fold open for service. The trick is to find everything at once
so you dont have further chain reaction failures.
