Could I get a pic of the bulb? (looking directly into and offset with no flash but ample lighting)

They are pretty easy (most of the time) to see if they are bad, usually there is a visual symptom.

I have now replaced the lamp and re-assembled the TV according to the service manual. now that i put everything back together, the TV is giving me a different error code. it is now giving 4 blinks. This apparently means that either the fan is not getting power or the fan connector is not seated properly,the temp is too high or the connector on the H3-H4 sensor board is not seated properly. I have checked & rechecked the fan over and over. no issues with that. and now I have checked the G2 board itself and that is seated properly. it isn't overheating and also. one more thing. I don't remember ever removing or replacing a H3-H4 board. where is it on this system. I can provide a picture of the assembly.

Lamp Was replaced, and all the Fans Were Cleaned with compressed Air. The Issues Ended Up being a Busted and old Lamp & dirty Fans. After That was completed The unit was re-assembled and tested For accuracy. System Works as It should. I Appreciate all the Valuable Help I received from Tom66!!! You are a Gem! Thanks Bro and I hope I can bring some insight to you or anyone else on This site about issues In the future.
