There is a fan in the back. Make sure that the fan is spinning and that the grille is clean. It is possible that the sensor is bad too.
Keep us posted.

Error Message


If the set is only 3 1/2 months old, you should still have warranty coverage. Opening up the unit will void the warranty, so don't open up the set. Call for warranty service. In all probability, the air flow sensor is defective. The message you are seeing is a result of the air flow not being detected or not sufficient. In any case, this is a covered problem and should cost you nothing to fix.

most rear projectors will turn themselves off whenever the lamp is dead. what we call protective mode. in this case the yellow light may be for the lamp. otherwise check if all the fan are working properly.

Error Message


. Set shuts off after displaying the message "TV will shut down in a few seconds. Please check if the air flow is blocked." After shutdown, it may have a yellow status LED, self diagnostics indicates error code 38. To repair, replace the Lamp Thermal Sensor with the new version, part # 299P313010A. The sensor is located on the Lamp Cartridge Housing. See Service Tip VS-72B. Under rare circumstances, when a replacement thermal sensor is not available, refer to the original Service Tip, VS-72 (page 2 and 3 of VS-72B) If error 3-4 then this maybe problem:. Check to see if the lamp is on when the unit is off (in standby) if it is components on the Power PWB... K9A20 and/or K9A21 are shorted. Also, R9A02 may be open. Possible side effects ... deformed lamp exhaust duct and damaged lamp. Replace PWB-POWER part # 934C228003 and if necessary, Lamp part # 915P049010, Lamp Exhaust Duct part # 642B155010, and/or Lamp Exhaust Duct Cover part # 642B156010. See Service Tip VS-73 2. If the lamp never lights suspect the Lamp part # 915P049010
