    My pt-43lc14 air filter light came on, so i went to pans web site for auth service center. Had 1 in my area. Talked to them, they said they never heard of this and was aware of no filter. They said a good cleaning at about $180 might help. I purchased some compressed air in a can, took the back panel off, cleaned everthing I could get to. then did near the bulb. I then left the tv unplugged overnight for hard reset. So far no problems (2 months later). Never found a filter!

I received the Air filter warning twice. I removed the back panel and used a HEPA (Shopvac) vacuum to clean the exbosed back and removed the sanp panel and cleaned the front. I did not remove the front bulb panel underneath the snap cover. Never found a filter and I have this model number. The warning has not come back so far.

This may be a temperature issue there is a thermal sensor that tell the tv its to hot and need air so it think its filte is cloged. make sure there is plenty of clearance for air flow.. however there may be more involved problem with the set ... the sensor could be failing

Panasonic PT-43LC14; I changed the lamp. I still get the lamp meter warning on the screen when I turn on the TV. How do I reset the lamp meter?


Here is the procedure,

1. Turn on the television
2. Press the volume down button on the TV display (not the remote)
3. While pressing the volume button, press the "split" or " PIP" button on the remote.

This should solve your problem.

Thanks for using FixYa and for the great rating!!

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.
