Question about Projection Televisions
We looked at the schematic and found that we have 3 out of 4 Resistors
blown on the ABL circuit we get no sound and no picture just a click
that the television
is attempting to turn on. Other than that all the rest of the boards
seem to be fine with no signs of being blown. we are able to solder new
resistors in once we find them, any recommendations on where to find
1/6 watt 22k resistors. The real question though is what could have
caused this and if we possibly have a larger unknown problem that might
lead us to not make an attempt to fix.
My Toshiba TZ55X71 projection screen tv has similar problem, red light flashing, just clicks on start-up and dead thereafter. Opened rear and front cabinet sections, looks like a bunch of %^$& I cannot fix... or maybe.. please
anyone help on simple troubleshooting. I have digital multimeter and basic electronics skills, just need a flowchart or something to start off with...
It sounds like a flyback problem (the part is around 70.00 but it can hold high voltage so have a pro do it!
