    Husband is cleaning the filter on the front by the lamp now. We heard there are 2 filters. Do you know where the other one is? Also, will we need to reset something in the service mode to get the 'air filter needs cleaned' message to stop coming up after we have cleaned it?

Hi,

Please find the manual from here

http://www2.panasonic.com/consumer-electronics/support/LCD-Projection-TVs/model.PT-50LC14

says "An OSD advising “AIR FILTER CLEANING...” - Please consult your nearest dealer.


The filter is undoubtedly near the projector lamp. There has to be a lamp cooling fan that pulls air through the filter.

There is some advice on HDTVoice.com -

http://www.hdtvoice.com/voice/archive/index.php/t-3843.html

It looks like replacement instructions are available with the replacement lamp. Here is an excerpt from that web site:

From the Panasonic Operating Manual-model # PT-43LC14/PT-50LC14/PT-60LC14
TY-LA1000

Lamp unit replacement period
The Lamp is a consumable item and it’s life varies based on individual usage.
Panasonic warranties the original Lamp for a period of 1 year from the date of purchase.
• The unit will detect when the Lamp’s end of life is approaching and the following message will be displayed.
• The LAMP indicator light will be lit when the Lamp’s end of life is approaching.

THE LAMP NEEDS TO BE REPLACED,
AND THE LAMP HOUR METER NEEDS TO BE RESET.

Refer to the instructions enclosed with the lamp unit (Part No.: TY-LA1000) when replacing the lamp.

• Please wait more than one hour for lamp replacement.
[ If you need to replace the lamp more urgently ]
• The projection display has a forced cooling feature. After the POWER button is turned OFF, and sometime during about the
first minute of the normal cooling fan operation, press the VOL+ button on the projection display and the ? button on the Remote control at same time for more than 5 seconds. The cooling fan operates for about 10 minutes.
In order to access and clean/replace the filter for that chassis, you will need to follow the procedure for removing the light engine assembly. This is the reason that there is no access for a normal owner and the requirement to have it replaced professionally (personally I find it a bad design) in the owner's manual.
The procedure for disassembly should be included in your SM depending on what you have. (I work with the HTML version which has it in Section 5)

You can access the filter from the front of the unit.
Pull off the cover(it unsnaps)

remove the 4 screws in the center and remove the door (not the lamp door)

there is two sides to the filter, vacuum the top side, and use canned air to blow out the bottom side.

Personally I do not use air to blow dust around but this is an option if you choose this way.

    The only other filter is in side the set by the lamp. Once that one is cleaned also then the onscreen reminder will go away. There is a sensor to tell it that the filter needs cleaned.

    The in side filter



    The replacment of the filter is very difficult. Not recommended for most consumers. The filter is located under the light engine. The light engine is expensive and easily damaged. I will reccomend that you call a TV repair shop to have the filter replaced. Click here for information on resetting the lamp.



    How to reset lamp and filter on screen display.



    1
    Be sure the power cord is plugged

    into a properly grounded wall outlet.

    Then, press the POWER button on the

    projection display or the remote control

    to turn the unit on.



    2
    While pressing the VOL- button on

    the projection display, hold down the

    PIP or SPLIT button on the remote

    control at same time for more than

    5 seconds.
