    Cable is straight to tv. Only things connected to tv are cable and x-box.

Toshiba 42H82, no sound after fixing hyperboard.


Search for the audio amplifier - it's a chip with a radiator on it - the jack for the speakers should be close by.

Toshiba 42H82 RPTV: Sound but no picture


It sounds like the 200v supply to the crt's is missing. this is the source for driving the tubes, other than the high voltage generated by the flyback transformer. If the set got really bright gray with wome white lines that are kinda on a diagonal, this is generally the cause. the source for this voltage is a diode on the secondary of the flyback transformer.
