Question about Panasonic PT-61LCX65 61" Rear Projection HDTV

Air Filter Cleaning

I have a 61" Panasonic TV. I keep getting the message "air filter cleaning needed" and the TV shuts off. I have had a repair man look at the TV and he can not figure out the problem. I saw in one of your help articles where you said that Lamp sensor may be defective. Can you tell me where the lamp sensor is and if you have any other suggestions to get this message off my TV.

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

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".

Panasonic PT-60LCX64 Air Filter Cleaning


Cleaning filter for the Panansonic PT-501LCX64.

I just had a T.V. tech do this. The filters are located on the two removable filters on the back side of the T.V. They look like the speaker units. He removed those two units, unplugged them & set them on the floor. He took some type of electronic cleaner with a cloth & wiped them down. The filters themselves are plastic. He explained that air flows through some tube connected to these plastic filters for cooling down below. He admitted they didn't look dirty--put everything back together & it is working fine now.

I imagine that dirty or not the timer is automatically set for every 400 hrs. of use to give you the prompt that the filter needs cleaning & will shut off in one minute so you can call a T.V. tech?

So to reset the timer--follow the other detailed prompts listed on this board & or use your owners manual & follow the prompts for replacing the bulb. That should take you somewhere to reset the timer--so you have another 400 hours of operation.

I believe it's with the T.V. turned off--hold down the down volume on your tv itself while holding the swap button on the remote control for 5-7 seconds---then follow the prompts. You should see a prompt for replacing a bulb & then one for filter cleaning. Then just reset the timer.

Hopefully this will help?

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.
