Make : Philips Model : PR1912B101 Problem : Loses sync & goes to a blue screen. Pressing the menu button will remove the blue screen so we can see the unstable image. We looked over board (Looks like a funai chassis) for cracked solder connection. Problem is NOT vibration sensitive. Does anyone have any tips or chassis info on this set?
