JVC NV-55BX4 will not power up with convergence power plugged in.
 

The power LED is bi-color red and green.

Plug TV in, LED comes on red steady. Press power remote or projector
tv itself, tries to power up but LED stays red and modulates
brightness of LED raqidly for a then stops and stays solid red.
Unplug the power plug for convergence board mounted in front panel,
plug is four of voltages (two volts, two sets of positive and minus
voltages for the convergence section, I restate; have that unplugged
will allow projector to start up normally. Changed all 3 amps
STK4274 ICs and checked for shorts. Nothing found yet.

Seen this before?

Cheers,
