It is as simple as getting out the schematic and test equipment and
troubleshooting the tv set for the problem and effecting a proper and
safe repair. Start by trying to find out which of the many protect
circuits is shutting the tv down, then working backwards from there to
the actual fault.

Simply guessing and replacing parts can get very expensive.

I have a Mitsubishi VS-60803 CRT Rear Projection HDTV unit. It has this
problem where when it powers on, the green power light flashes on, then
shuts off half a second later. No image appears on the screen. There are
also four evenly spaced clicking sounds: the first two coincide with the
flashing, and along with the third, there is a quick, high-pitched whining
sound. The clicking is coming from the vicinity of the flyback
transformer.

I've opened up the back and made a cursory check, seeing no burned or melted
parts. What further steps can I take to isolate the problem? Would it
likely be as simple as replacing the FBT?

Thanks
