Flashes in what way?

A pulsing picture or video dropping entirely?

Do you hear any high voltage pulsing from the back?

Check the B+ voltage and see if it is pulsing.

You'll have to measure that on the bottom of the main pcb. Look for a large filter capacitor. Read the voltage across that (probably in the neighborhood of 150 vdc).
