Set came in with flyback defective. Replaced flyback , set now has picture
but no audio. Set tunes channels and all on screen menues are ok. Chipper
check says e-prom is ok. Audio is ok from pin 6 on u12101 to outputs. There
is no signal present on pin 47 of u12101. Replaced u12101, cr12301, and
checked all componets around this area. All voltages are correct except pin
49 on u12101 is 7.24 volts instead of 3.4v. The audio input jacks have audio
and volume control varies up and down when a signal is inserted there. You
can hear hiss noise in speakers at very low level. Thank you in advance.
