Question about Mitsubishi WD-62725 62" Rear Projection HDTV-Ready Television
The lamp in my set blew after being used for a couple of thousand hours over max life. I replaced the bulb with a new one and got the same problem as many others, error code 34. The set shuts down after a short time and the lamp light stays a steady red. I've tested the new lamp and think it is bad, but I would like to know the correct voltage to look for on the lamp connection before I put in another lamp. I'd hate to blow another bulb if the problem is not with the lamp itself.
(Lamp may light and go out) suspect bad lamp part # 915P020010 2. Check for 12-volts DC at J-9 connector pin 4 on the Engine Driver PCB, if missing check for an open F9A09 on the Power PCB, if it is open replace F9A09 part # 283P127060 and the Light Engine part # 939P977020 3. (Lamp may light and go out) Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if low or missing check C9A37 and C9A38 both 3300 UFD 10 V part # 181P732040 on the Power PCB (part # 930B921002) 4. At power on the lamp turns on and off three times and then the unit shuts down with a red lamp LED (lamp error). Replace the Light Engine part # 939P977020 5. Lamp enable line at J14 pin 6 does not switch to 5 volts after turn on, 12 and 5 volt supplies are good. Suspect the Light Engine part # 939P977020 6. Lamp enable line at connector J14 pin 6 on the Engine Driver PCB switches to 5 volts after turn on and does go to 0-volts (low) after 5 seconds, 12 and 5 volt supplies are good. Suspect the Lamp Power PCB (ballast) part # 939P978010 7. Lamp enable line at connector J14 pin 6 on the Engine Driver PCB switches to 5 volts after turn on but does not go back to 0-volts (low) after 5 seconds, 12 and 5 volt supplies are good. Suspect the Light Engine part # 939P977020 .
