Subject: [TechAssist] hitachi projo converg.
I went to the home to ck out a model 43uwx10b chassis dp14g for bad
converge. Changed the stk392-110s and four resisters out on the converge
panel. It came on withworse converge then before and after 10 minutes or so
the IC's got real hot and the set shut down. Changed the ICs again same
thing. Anyone have any idea what's going on. Help would be thankful for.
Avery.
