Toshiba Model 57H83 Rear Projection TV Lost Picture and Sound

the most common problem in this set is convergence---two chips are used and if one shorts what you have happens--only way to prove this is get at and unsolder all 18 pins on both chips----if set turns on then the chips and or a resistor near them are bad.

I have a toshiba 50hm67 tv and with mine the blue light would come on and I would hear sound first and then the picture would finally come on... this happend for about a month.... next the yellow and blue light would come on but the pic still wouldn't come on until it clicked off and on by itself for about 10 min this went on for about a week. All of a sudden last night the red lights by the power light started blinking. No tv now and when the tv shut off it said lamp not working.

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.
