SOURCE: Lamp Light Red - No Screen Image

It could be the a problem with the lamp ballist circuit, or just a bad lamp socket, or simply a bad lamp. The only way to tell is to call out a servicer as that would be alot less expensive then to get a new lamp and then that not be the problem. These problems can be a little hair pulling at times, thats why i have no hair left!! LOL Good Luck

SOURCE: Replaced lamp and now can't get a picture

Hi Sally Jo, Unit powers on and works properly for a while then shuts off with a red lamp LED (lamp error). Suspect bad lamp part # 915P020010 2. 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 3. 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 4. 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 5. 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 6. Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if missing replace the Power PCB part # 934C148001. Hope this helps!

SOURCE: Mitsubishi WD-52525 Failure

Who needs a repair manual when I have you guys!! Last weekend, my 52525 died almost three years to the day. So rather than throw it away or spend hundreds (not to mention the inconvenience) of dealing with a repair shop - I read your posts. So I dismantled the unit (easily with all the great advice), found the swollen caps, ordered replacements from Mouser, installed, reassembled and the set works perfectly. Also cleaned and realigned the mirrors while it was apart. Like a new TV. Cannot thank you guys enough. Not to mention my family thinks I'm a hero!!

SOURCE: just replaced the lamp on my mitsubishi wd-65732 2

if you used an OEM lamp rather than an original ,it may have gone out. The more expensive original bulbs last longer

SOURCE: Mitsubishi WD-62525 Red Status Light After Cap Replacement

Mitsubishi V26 error code 41 with solid red status indicator is caused by leakage from capacitors C9A37 and C9A38 (3300mf/16v). The result is a bad fuse F9A02 (15amp pico) which reports error code 41 indicating short protect. The Mits part number is 283P144040 but any PICO 15a fuse will work.

I have read another solution which may indicate the light engine has failed and will likely need replacing. The cost is quite expensive. $1500 range and apparently the part is no longer available from LG. Best you might do is get an estimate to repair just to be sure.

No picture, siren type noise as restarting


My Toshiba dlp 62hm116 was used for 3 months then stored for 2 years, I turned it on yesterday and it makes a loud grinding noise which I think is probably from the exhaust fan area and the picture is black except white at both vertical sides. It worked fine the last time I used it 2 years ago. Any ideas?

Panny pt-50lc13 steady amber flashing light


Sounds like a defective lamp diever or ballast.Listen for a buzzing sound when you turn the set on. If you do not hear it then most likely you have a bad ballast or lamp driver. Worst case scenerio would be the engine itself.
