Sony KP-43HT20 (RA-6) Chassis

(1/1)

Gravityboots:
Cannot converge this set and sadly, I'm without a service manual. All ideas or experience welcome. 19 years on the job and counting.

Gravityboots:
After discussing this problem with another well informed individual on another web site, it has been proven conclusively to be (2) STK 392-570 ICs and (2) 5 amp pico fuses on the power supply board that are responsible for this failure.

Problem solved!
