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!

You have to take the TV apart. Pull the electrical chassis out and look for bad electrolytic caps on the boards. The red LED probably means the 2 - 3300UF caps on the power supply board are bad. You can tell if they are bad by the fact that their tops are puffed up and they may or may not be leaking brown fluid. Compare them against the other caps on the boards and you will see how they have flat tops.
BUT before you take the TV apart you can check the error codes by pushing "menu" and "Device" at the same time and holding for about 10 seconds. The status light will blink two numbers. ex. one flash pause two flashes is 12 Error Code Probable Cause
12 No error detected
22 Recovery from momentary Reset
32 Lamp Cover open
33 Air Filter Cover open
34 Lamp abnormality
35 Chassis Fan failure
36 Exhaust (Back Cover) or Lamp Ballast Fan failure
37 Engine (DMD or Lamp) Fan failure
38 Excess Lamp Temperature
39 Excess DMD Temperature
41 Short Detected
44 DVI Cable (between Chassis and Engine) disconnected

You can buy replacement caps from Mouser electronics online. There are plenty of solutions detailing how to do this already posted.
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: replaced wd-62525 lamp, picture dim
Cleaning the mirrors will not increase the brightness much. I would double check the lamp setting in the Menu and also the setting of the picture and brightness settings. Many times these are adjustable independently for different inputs. Besides this, I would look at the Ballast and or the Power Supply to cause the problem. I would recommend a professional to look at it if it is not correctable from the Main Menu of the set.
Hope this helps,
