Mitsubishi wd-y57 shuts off intermittently and red lamp light comes on. TV can be turned back on after a minute or so and usually works fine for days.

After buying two lamps (at a cost of $500.00) we had to call the Mitsubishi service man. He came out at a cost of $150.00 (his appearance fee), and told us right away (after taking out the lamp that we had newly installed) that the socket was smushed/smashed. He then went opened the set from the back and tooled around, and unsmushed/unsmashed the socket. We were so happy. On installing a lamp we all must shine a flashlight into the compartment so that we can see what this lamp is going to connect to. Just like a lightbulb, there is a socket on the left inside of the compartment that the lamp must plug into. From our dark vantage point we could not see this, and with the newly manufactured lamps, which are not the same configuration as the old, it is a very tight fit and this connection socket is vital -- or the set will not work. I wish they would have told us this. That lesson taught to us by the Mitsubishi service person cost us an additional $100. Well anyway, we are sharing it with you. Good luck. Maryland

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 # 939P977020 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 # 939P977020 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 # 939P977020 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 # 939P977020 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

Mitsubishi has problems with the thermal sensor going bad. They extended the warranty for several sets. The sensor is right by the lamp. Call mitsubishi and insist they do something for you. If you keep playing your set, the bulb could also be at risk. I would think your set is covered being a 62" set. Good-luck and be sure to act ASAP.

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.
