The switches (there are two of them) can be bypassed but it isn't a fun job. There are 3 connections on the switch boards and if you connect all 3 together, that should bypass the switch. There is one switch on the door and another located on the lamp socket board. You can bypass on the door but there is no way I can describe how complicated it is to get to the one on the lamp socket. So, try jumping the one on the door and see if helps. REMEMBER THAT THE LAMP IN THIS SET CAN CAUSE BURNS, VISION DAMAGE AND OTHER PROBLEMS SO AFTER YOU HAVE JUMPED THE SWITCH, PUT THE DOOR BACK ON AND MAKE SURE YOU HAVE THE CORD UNPLUGGED WHEN YOU WORK ON THE TV.

3 times blink error code shows Lamp Door is not seated / fixed properly, please recheck it and make sure that door close safety switch is pressed as this switch sends error signal to system control chip.

There is the possibility that you might have a defective ballast, it might not have enough voltage to keep up with your new lamp, and that's why it switches off and makes the 3 indicator lights flash, letting you know that the bulb is defective, but it's not the bulb, it's the ballast
