HELLO TECHS,---- I HAVE A MAG. PROJECTION TV, CHASSIS # PTV 835. MOD # 9P5534C102 ABOUT 5 YEARS OLD. I HAVE A FOCUS PROBLEM. THE PICTURE IS TO SOFT. I CHANGED THE COOLANT FLUID. BUT NO HELP. IT HAS A REALLY GOOD COLOR PIX, BUT I CAN'T SEEM TO FOCUS IT ENOUGH. I'VE ALREADY CHANGED THE FOCUS CONTROL ASSY. BUT NO HELP. I HAVE ADJUSTED THE LENSES, BUT THAT DON'T HELP.THE SHARPNESS CONTROL AND THE CONVERGANCE CONTROLS WORKS OK TO .I WAS WONDERING IF THE 130 VOLT SUPPLY WOULD HELP IF I INCREASED IT A LITTLE TO SEE IF THAT WOULD GIVE ME A LITTLE MORE FOCUS VOLTAGE. THE CUSTOMER SAID IT JUST HAPPENED SUDDENLY ONE DAY WHILE THEY WERE WATCHING IT . ANY HELP WOULD BE APPRECIATED. THANKS -----J.C.

have you checked you mirrors for being dirty & secure? is the clear protector screen clean? is the front screen in the correct way & sturdy? i can't think of anything else to try. from (old dog)
