[TV] Re: RCA, ATC113CA1 strange

["John Conti" <contitv@xxxxxxxxxxx>]

Don, Hear are some tips on the ATC113. I don;t know if this will get you 
going but its a shot in the dark.
Check to see if this model has the following parts. May not pertain to you 
chassis
check TP20, Also there a 1 meg resistor that can open and cause no startup
Replace all the active components in the primary, the opto TP22, the 
TP23voltae reference ic, and any transistor direct coupled to the opto. in 
the secondary. Also resistors touching the power tranformer, base, gate, and 
emitter source.

Also check for conductive glue under TL092 .

Good Luck . Those can give a headache real quick.
