Replaced lamp first tv worked for a few minutes then picture deteriorates finally shutting down. Replaced ballast and tv is still doing the same thing. Great picture at first then it deteriorates finally shutting down with a solid red light on the front panel.
Maybe a power regulatr card issue?

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!

Make sure that the lamp cage is seating well .. then make sure the door is closed properly. there is a door switch and if the door dont close right the switch may be telling the set the lamp is out.

Could be the FMT pcb or the Dm pcb board you should check the caps on them and replace any faulty ones.
