I have an issue with my DLP TV. I turn it on and all is well for about 2 minutes. Picture quality is excellent. The Timer/Power light is constant green, which mean the TV is on. After about 2 minutes the TV picture and audio turns off and the lamp light turns red for about 2 seconds. Then, the lamp light flashes green for about 1 minutes (This I assume is the TV cooling off per the manual). Finally, the TV turns back on and the picture is excellent. That is done AUTOMATICALLY! I do nothing to turn the TV back on. I have unplugged the TV, but that does not help. I don't know where the reset button is, so I wasn't able to push it. Can you please assist me with my issue? Is this the standard for a lamp failure? I would guess that if the lamp failed, the TV shouldn't (and couldn't) turn back on automatically. I took the lamp out for inspection and did not notice any issues, but I am not an expert.
1. 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 low or missing check C9A37 and C9A38 both 3300 UFD 10 V part # 181P732040 on the Power PCB part # 930B929001

Did your replace lamp come on the screen or did you lose picture? Just because the LED indicator suggest replace lamp it doesn't mean it needs it. If your pix was dull or loss of brightness then replace it, if not then just reset your lamp timer, check your owners manual for instructions.
