it was audio out board. i plugged the horiz driver xistor back in. its not
dead anymore. although somtiems it turns on now. sometimes it doesnt. but if
i plug the audio board back up. it wont work at all.

Hi..

When it won't turn on (with audio disconnected) take a look at pin 22 of
1001. If it's more than 1.5v, something else is in protection mode.

Take care.

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. ;-)

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.

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.
