Same w/ mine. Repairman said they turn off auto to protect the set no matter what is wrong. Take it to be fixed. Mine was right at $100. Works great again.

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

ok.
#1. replaced capacitors on power board. DM board FMT board .
# 2 on power board you need to chek caps. 3300mf x 35 v.QTY 2.
# 3 12 capacitor 1000mf x 16 v.
If caps 1000mf x 16 v . looked good. replaced anyway......
if the light just constantly blicks green and doesnt stop. You will need the" V26 DM repair kit " which will usually repair that issue. You can get the repair kit at the following link which includes the replacement capacitor and instructions

You need to replace the "light engine". This is very very difficult. You need to take it to a repair shop. But this will be very expensive. Around $1,000.00
