i need a cross reference and/or schematic/datasheet to the audio out IC.
only markings on it is 51135, assuming a factory assy run number or some
cryptic code.

ok i replaced the last 2 capacitors on teh secondary of the main SMPS
unit, the set now comes on and works every time. YAY. finally. but the
audio is dead. as soon as you plug in that little conenctor, to power up
the audio amp, set wont start at all. no horiz pulse, like before. the
power supply is smooth now. at least until you plug in the audio
connector. then the power supply loads down again.

well then it has to be a cap or somethign liek that. because when it does
turn on, it plays beautifully. perfect pictuer. just no audio. ;-)

Got this set, it would turn on and fire HV for a second, then shut back
down. it wont do it anymore, only did it one time.


I monitored C4118 while pressing the button, it would start off at 13.1
volts, and drop down to about 5 volts. when power button was pressed.


I then replaced CR4118, and replaced 2 caps in the IC chip of the power
supply. the main B+ at standby levels is about 143vdc. the 15v standby
is about 13.3 still.


but this time, when you press the power button, OR perform the manual
power-on, bypassing the micro unit, the voltage doesnt drop anymore, but
the set still is dead. HOT is fine, chopper is running. I dont know what
to look for next.

however if i hold the board in manual power on, every once in awhile the
degauss relay would start clicking on and off a little bit, very
faintly, like a weak supply somewhere.

any ideas?
