bemc:
Faulty circuitry in and around vertical output chip circuitry and/or
faulty chip or other related parts.... diodes, resistors, high ESR
electrolytics, etc. Most probably faulty, dry, high ESR electrolytics...
without an ESR meter you can only guess.
Standard testing and troubleshooting procedures will diagnose this
specifically.
You may want to go to the website for this newsgroup at
http://www.repairfaq.org
there with some searching you will find helpful information ... or
TAKE it to a repair shop for at the very least a repair cost estimate so you
can make an intelligent repair decision with facts instead of internet or
telephone wild guesses. This is usually a very economical and
straightforward repair at most shops.
