Right,
I changed back to Original Y buffers first - [B]No change[/B] - Still Flashing Red Screen
Then I changed back to the Original X Board - [B]No Change also[/B] - 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 [B]Humming...

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

Ok, got the parts and did the following :
Changed the X main board - but there was no difference in the display
left the X-main in and then changed both the Y- buffers - this caused the screen to turn totally red and began flashing in 1 second pulses.
I did notice however when changing the X main, that of the 3 ribbons on the right that connects the screen with the board :
The Top one was OK ie. the gold band was in tact - mostly

Re: Philips 42" Plasma - Model 42PF7320A
What brand should I buy ? Samsung or Phillips ?
The Original in the TV now, is Samsung but when I bought the Sound Card last year, I got Phillips - which is working well.
