Re: Projector self power off

Have you tried looking to see if the lamp has expired? Or could simply be cause by a faulty power supply unit?

Projector powers up, after 2 minutes image goes away, projector goes into cool down, then shuts off. why?

FAULT: lamp of your projector is faulty.
Experience: when lamp life is near to end and environment temperature is too low you are facing the same problem and if you are facing this problem in normal temperature then also lamp is faulty.
Sulotion: Just replace the projector lamp

Shuts off after approximately 2 minutes

I have exact same problem. According to the manual its time to replace the bulb. But when I check the runtime on the bulb it shows 326 H. I am not certain if this is the remaing hours on the bulb or the usage to date hours.

I would appreciate anyone commenting and recommending a solution.

Help me!!!!

Hello folks! I bought my unit on 11/2006. After 1532 lamp hours on eco-mode, my unit would start shutting off after just 2-3 minutes. Same problems you guys are having. Based on the comments I've received from the TECH guy where I purchased the unit, it appears that these units have IRIS problems. Here's how you can tell if its an IRIS problem...according to the TECH guy:

1. Get the unit powered up as usual.
2. Wait until its projecting enough light to see a menu on the screen.
3. Using the remote control, PRESS the "POWER" button again to see the power off confirmation screen, then PRESS the ARROW keys in the following order: RIGHT, UP, DOWN, UP, DOWN, then PRESS ENTER.
4. The EXT OPTION menu should then be displayed.
5. SELECT the "SELF CHECK" option using the arrow keys.
6. Look for the word "IRIS. If that word or any word on that line appears in "RED" color, then the IRIS is faulty and needs to be replaced.
I just called Panasonic's Service dept. and they gave me a CASE NUMBER and asked me to FAX my original INVOICE to them. She told me they are going to review my claim and see if they can provide assistance or whatever. Apparently...Panasonic knows of this problem according to the TECH guy at the place where I bought my unit in late 2006. Good luck! Steve 717-891-2062
