Question about Televison & Video
Greetings, This is direct from the Sony Service manual
9 times, Diagnosis: Audio error. Possible causes: +- 19V line is shorted. (A, B boards), IC708 is faulty. (A board), PS701 or PS702 is opened. (A board). Symptoms of the problem: No sound or picture. Fails to start
Because of the intracies and risks of electrocution and radiation in this repair I suggest you arrange for a tech, rather than to attempt it yourself. Often changing the faulty component or the actual boards, fails to resolve the problem totally as it may have become damaged deeper into the circuit.
Thanks for using FIXYA
