Re: air filter

Is your set under warranty? If not, bite the bullet now and get the service manual - you will need it sooner or later.
Whether there is a way to reset the warning or not, a solution is needed for the problem of restricted airflow and you will need to take off teh back panel and blow out the dust using compressed air and while your in there, look for any filters in front of the fans.

Warning light comes on that T.V. will shut off in one minute & to call a technician to clean air filter.

Sounds like a plasma, or projection system. Find the fan inlet filter, remove the foam filter, and vacuum with a dust buster. You can use a can of compressed air to blow the filter clean, too.

Air filter cleaning

Air Filter Cleaning for Panasonic PT-43LCX64 PT-50LCX64 PT-60LCX64

OK, I purchased the service manual which explains it pretty good. However it is pretty complex with about 45 screws to be removed so if your going to attempt it buy the manual (mine cost $14.99). There are 3 filters, one at the back and two at the front. Once the procedure is completed there is nothing else to do other than switch it on. There are no timers to reset in the software like some other models. So there must either be an airflow sensor or a temperature sensor. I'll look at the service manual in more depth when I have a chance.

I do have a request for someone. The filter at the rear was pretty clean as was the one on the top part of the projector assembly. The one at the bottom of the assembly was dirty. I think that it might be possible to clean the front filters far more easily. So if anyome wants to try it here is a possible solution.

Remove the front panel (silver). Undo the 2 screws on the cover of the projector housing (not the one that gives you access to the lamp. Remove the cover. Carefully vacuum the top dark grey foam filter on the left side of the pojector unit. Next vacuum the bottom of the unit. That's were the main and dirty filter was. You can't really get to it but I'm hoping you might just get enough off to get it working. The TV senses if its clean enough so there's nothing to loose by seeing if this shortcut works. Once the error comes back I will try it myself.

Good luck

Unplug the unit! Pull off the access silver panel from the front of the tv. there are 2 sma ll access panels on the front behind the silver panel. The one on the left, allows you to change the bulb, one screw to remove, Just to the right of it there is a second one. This has 2 small screws to remove to access the opening. Once you take this small cover off, you will see the fan compartment. On the top of it on the left side is one small filter, mine was pretty clean. The bear is the one on the bottom, that you can only see the edges, but there is a small opening on the bottom. It looks like it is suspended in mid air. Take a cue tip and clean the underside! I slightly wet my cue tip and it worked fine. I tried to remove the fan compartment, but it would not come out and I did not want to force and break it. Remember to unplug the unit first. After I used the cuetip on the filter, I have a small vacuum and cleaned everything carefully. I had heard to leave it unplugged for about two hours to let it clear after I reassembled the covers. I turned on the set and the message was gone and has never come back. I did not have to reset and worked for me. That was it for mine and it is working fine

Air Filter message

Soulvisitor has it right. I had the same problem and the stupid tv would shut off after 1 minute. We opened the silver front panel , took the bulb out cleaned it, took the cover off the grey box to the right and very carefully vaccumed the filter and wiped it off with a microfiber cloth. It works great now!!! Make sure you unplug your tv before messing with it. Thank you Soulvistor you saved us at least $100.00
