I will replace the original Y buffers tommorrow and check to see if the flashing stops.

Presently I do not have a Digital Voltmeter, but I believe I can buy one.
No oscilloscope available

Right,
I changed back to Original Y buffers first - No change - Still Flashing Red Screen

Then I changed back to the Original X Board - No Change also - Still Flashing Red Screen

I did notice that there were 2 Green led lights on the "A2 board" don't know it proper name - [ photos attached ]
One was Solid green ( inner ) and the other was blinking (outer, closer to the A2 writing ) in the same sequence as the flashing of the screen.

Also there was a Humming sound coming from the Y Main board area, the hum was in the same sequence as the flashing of the screen. and blinking of the green light.

Does this mean anything ?

It sounds like you got a defective Y-buffer board which has caused damage to your Y-main board.

tom,
Have a Phillips 50PF9630A with smeared blotchy picture. assumed X sustain was bad - checked x sustain IPMs, checked out good. I see you mentioned something about a cracked resistor on control board - do u have any more info on where this resistor is located ?? Don't believe my x-sustain board is bad. no bad caps, voltages are good, panel comes on with smeared blotchy pic, menu button does nothing visible. do u remember old post heading ??? thanks
