My old Sampo PME 50X6 still gives a better picture than any that I have evaluated, including my new Panasonic 50PZ80U, but the PME 50X6 picture flickers, especially when the overall picture content is bright. Poking around on the boards showed some sensitivity when the PW 0500 Aux power supply board was poked and prodded, and since I have no schematic, it's punt & guess and I went ahead and ordered a new PW 0500 from "Discount-Merchant". If anyone has access to a PME 50X6 schematic set, I am interested in buying. Also if anyone has any suggestions as to the fault, I would be interested in hearing them.

Thank you!

Harvey,
What do you mean by flickering picture? I'm not understanding... Is it red dot's on the screen? Is the screen shutting off and on?

Red Dots can be caused by improper voltage going to the plasma panel by the X and/or Y Sustain boards. These boards normally have potameters to adust the voltage (Be careful doing this). As the plasma panel gets older the voltage required to operate the panel changes, also as the boards get older the modules on the board get worn out and can cause inconsistent voltage output.

I hope this helps!
