Question about Projection Televisions

Toshiba 55H70 Wont turn on but we get the blinking light of death

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...

    I had a professional come out, in minutes he found several resistors
    blown - he called it a conversion or something... parts were @ 80.00
    and he took the board out and said he will work on it at the shop...
    I admit there are just a few things that I should not work on, and this is one of them...thanks for the help.. Matt

It sounds like a flyback problem (the part is around 70.00 but it can hold high voltage so have a pro do it!
