Question about Samsung HLP4663W 46" Rear Projection HDTV
If Lamp and Temp LED blinking that shows problem with lamp cover safety switch.
Make sure lamp cover is placed in its position correctly so it can engage safety micro switch inside cabinet that tells system control chip that lamp cover is fixed. It is safety feature.
Service manual shows following instructions for lamp and temp light blink.
Check that the cover detection switch is inserted at CN107 on the Sub Detect/Actuator board when LAMP and TEMP LED blinks.
When LAMP and TEMP LED blink, check that the lamp cover is properly assembled and that the switch pressing boss(inside) is not bent.
let me know if you have additional question.
