Hello, My name is ***** ***** I'll be assisting you. I'm sorry you're having problems. In order to assist you, I need to ask for more info.
1) If the set wasn't shutting down like this until you replaced the lamp, then I need to ask you where you purchased this lamp from and for how much?
2) When it shuts itself of, what are the LED indicators on the front of the set doing? Please describe each light, it's color and whether it's blinking or steady.
3) What were the symptoms the TV had BEFORE you replaced the lamp?
Do you need assistance with this?
No thank you on the phone call.
There's two lights on this TV- the Temp LED and the Lamp LED.
Tell me specifically which LED is doing what when the set shuts down please.
Sorry, there's actually three- there's also the Lamp LED. These all indicate codes, so if you can tell me what each is doing when it shuts down, I can look them up directly and tell you what is wrong.
Are you still with me here?
Hi. Usually that happen to let you the time to reset the hours counter on the TV/Projector. I think this is the model of lamp you need and the associated hour reset procedure:
