Buna ziua, Romania,
Uploaded service manual to "Downloads" on this forum. As you are probably aware, Philips use a multitude of panels with different service manuals for each panel. The one I uploaded was the only one that had schematics. The power supply is fragmented to other areas of the TV i.e. not shown as a self-contained block. I hope it is what you want and is helpful. Otherwise your chances are 'None' and 'Buckley's'. Go to Service Manuals_Plasma_Philips in downloads.
