Filter cleaning issue

Where is the filter on this TV? We have looked in all the suggested places and have had no success. We continue to get a message about the filter needing cleaning and the TV shuts off. We have also tried the suggestion about holding down the buttons to reset the TV. We could never get the the message that we should've gotten. And after about an hour the message returned. We are totally at a loss and are in great need of some help. PLEASE, PLEASE, PLEASE!!!!!!!!

Re: Filter cleaning issue

So, this worked out Fantastic!! Thanks to whomever ('Guest' maybe??) put in the "Best Solution" info. So, 144 q-tip tips, 72 q-tips ends, 36 q-tips (if you use both ends of the q-tips, top and bottom), 1 cup of water, 1 good vacuum and 28 min. later, it's fixed!! Of course, this does not count the 10 min. it took to figure out that when you take out the two screws, the Black Box right in front of you is the fan. Yep, that's it. Yea, it took a few to figure it out. I started out by looking for a fan, that I figured out is inside that Big Black Box. And that 'rectangular black flat pad' on the left is the filter as well as the 'big black flat pad' that you can barley squeeze a Q-tip into underneath the entire black box. But I saved a ton of $$$. Hey 'Philbo' tell that repair man to go back to school and give you a refund.

Re: Filter cleaning issue

We found the air filter. Make sure the TV is unplugged. If you take the silver panel off of the front of the tv you will find two panels that can be removed by pulling out a couple of screws. The panel on the left with one screw holding it up is where the bulb is. The panel on the right with two screws holding up is where the fan compartment is. There are two filters in this compartment. On the top left side of the fan compartment you will find the first filter. The other filter is on the bottom of the fan compartment. The filters are just black foam pads. I used some damp Q tips to clean the air filters and vacuumed everything out when I was done. Make sure the Q Tips aren't too wet. After cleaning the filters, leave the tv unplugged for a while so it will reset and you should be good to go. Let me know if this doesn't help you. FYI, I didn't have to remove the fan housing, I was able to clean everything with it still attached, it just took some time...

Re: Filter cleaning issue

Try making sure that your cable box is turned on (if you have one) then try the volume down button (on the tv) at the same time as the tv/video button (on the remote).
If that works please post back about how you got past the first menu that does not allow you to reset the air filter hours...
We have the same issue and we cannot get past that menu.
I don't think we have an air filter???

Reset air filter

Page 58 of the user manual says that after cleaning the filter when the power is turned on, you will be given the opportunity to reply "Yes" to the question "Did you clean the filter". I suggest you go through the motions of cleaning the filter again, removing the necessary parts. Then replace the parts, turn the power on, and watch carefully for the message "Did you clean the filter".

You must remove the light engine then locate the filter by removing a black cowel looking device at top of engine held by 4 screws,then you will see the rectagular filter held with 4 screws you must pry out the filter it does not come out easy.

OSD Message Panasonic PT-50LC14 Air Filter Needs Cleaning

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.

Air Filter Cleaning

Call the factory for an authorized servicer near you, your TV guy doesn't understand Panasonic...

If the lamp thermal sensor is active, the fans just keep running because it thinks the thing is hot (to save an expensive part from exploding). It does not give any error message.

Fan 1 is used for air filter detection. (It's essentially the same run-sensor type fan used in their stereos.) Fan 1 plug P2902 at the right side of the light engine board may not be making good contact or the fan is not running. The micro must get the proper feedback signal from that fan to keep it happy.

Good luck, Mark
