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!

that means your lamp it is getting to the end of its life.
sometimes even if the lamp still good the TV will send you that message because that timer is closed to 5000 hours
What you can do is open the lamp door, closed again and the tv will ask you if you replaced it the lamp, and just say yes and that sign will go away
or just simple replace the lamp. 915P020010

SOURCE: Horrible burning smell from lamp
If you ordered it directly from sony then i would be concerned and contact the to have it replaced under warranty. If you did not get it directly from sony I would expect it is a rebuilt lamp or you purchased just the lamp part instead of the whole cartridge and installed it into the carttridge yourself. The lamp is designed to be replaced as a cartridge . The smell is probly a lamp that is burning the wires on the back side of the lamp because it is incorrectly inserted and the wires are touching the glass. Just a couple times i have seen a lamp that will smell slightly as the plastic and insulation heats up for the first time.But it only smells a little for like a day.
