I have a Mitsubishi model WD-60737 and to make a long story short 1st time problem lamp replaced fine for a month til my uncle hooked a DVD player to my TV next day turned on with solid green light then TV kept turning off after 2 to 3 minutes of beingetting turned on and a solid red light to show after. What does that mean? It's a brand new lamp and worked for a month so why shut down now? Could my uncle have did something to where it shook up the circuits or something?

If you have a voltage meter there are some things you can check.
Unplug the unit and remove the back cover of the set. Then Plug the unit back in.
You will need to tape down the lamp safety switch in order to do these tests.
Here are all the failures that would give you a lamp error and what to check.
Cause 1. Unit powers on and works properly for a while then shuts off with a red lamp led(lamp error). Suspect bad lamp and replace.
Cause 2. Unit does not power up correctly and you have red lamp led(lamp error). Check the lamp enable line at connector J14 on the back of the light engine. If pin 6 does not switch to 5 volts after turn on, but your 12 and 5 volt supplies are good, then suspect a defective light engine.
Cuse 3. At power on the lamp turns on and off 3 times and then the unit shuts down with a red lamp led(lamp error). You have a defective light engine.
Cause 4. Unit does not turn on correctly and you have a red lamp led(lamp error). Check for 12 volts at connector J9 pin 4 on the light engine. If voltage is missing check for an open fuse F9A09 on the power supply board. If it is open, then you need to replace the fuse and you still have a defective light engine.
Cause 5. Lamp enable line at connector J14 pin 6 on the light engine does go to 5 volts at turn on, but does not drop back to 0 volts after 5 seconds, but your 12 and 5 volts supplies are good then you have a defective light engine.
Cuase 6. Check for 5 volts at connector J9 pins 1 and 2 on the light engine. If low or missing check Capacitors C9A37 and C9A38. Values are 3300MF/10V. Replace capacitors if defective.

This is all I have and I wish you luck.

Red lamp light stays light


I doubt that it is the optical assy. it sounds more like a chassis problem either on the DM or the FMT board.

check out www.tv-techs.com
if it is a chassis problem it will cost about $250.00 plus shipping one way to fix the chassis

Sony Wega KDF-55E2000 won't turn on


A 5 blink code is a lamp power supply problem, but I would try a new lamp. I'd say about 90% of the time that fixes the problem.Get an ORIGINAL Sony lamp as the aftermarket replacements are ****. If you replace the lamp and still have the problem, you will need to have the lamp power supply/lamp ballast replaced

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!
