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.

Menu, options, filter time. When the filter time is displayed, press the reset button for at least 3 seconds. The reset menu will appear and you can select RESET.

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.

go into the menu. it should be in the same menu as the lamp timer. as for cleaning the filter, use canned air.
