Question about Mitsubishi WD-52525 52" Rear Projection HDTV
Mitsubishi WD-52525 52 The Lamp does not come on and I do get red light indicating the Lamp is bad. With a new Lamp installed it still does not come on. I measured 70 volts on a DVM inside the TV where the Lamp should plug in. 70 Volts can't be a correct output. I do not have any schematics. Can someone shed some light on what might be wrong ?
I had a similar problem when I change out my lamp - it would come on for 5 seconds then go out. I looked at the DM board, but the capacitors looked good. I did notice that two capacitors (3300uf 10V) were bulding on top. I replaced them and to my complete surprise, the TV worked perfectly again. I used Techman's suggestion on looking at the boards, but the diagrams and pictures weren't accurate. I just used my intuition and took it apart making sure I marked all the wires ( a ton of them!) appropriately. If you are mechanically inclined, it takes some patience, but isn't that difficult. It cost me $12.00 to fix, plus buying the solder and de-soldering guns. Good Luck.

1. (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 # 939P977010 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 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 # 939P977010 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 # 939P977010 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 # 939P977010 Hope this helps!
