Question about Panasonic PT-50LC13 50" Rear Projection HDTV

4 Answers

Light engine Our Panasonic t.v. keeps saying it needs the air filter cleaned out but we cant find the air filter too clean it. We just replaced the lamp about 2 weeks ago. Please help us!! Call Tech to Clean Filter Message!  Where is the filter?  Is there a reset? I was told that it probably needs a bulb, replacing should fix problem.  This is not the solution!  I was told to vacuum the rear of the set and the front housing, than unplug for 2 hours so memory would be reset.  Does not work!  I was told a $125 housecall, plus $175 minimun charge by a bonafide recommended repair person, and he would not guarantee a fix. Has anyone come up with a solution!

Hi there,
here is a forum that discuss the same problem you have.

Essentially, on the right side of the bulb compartment is the filter compartment. Open it from the front and you will see the filter. There is only one screw to undo.

Good luck

    Service mode info

    Enter Service Mode: With the TV powered off (make sure it's off for a few minutes before trying this, or you'll wait for the customary cooldown period before anything happens if you turn the set off and try this stuff immediately), press and hold both the "VOLUME Down" button on the TV itself and the TV/VIDEO key on the remote control simultaneously for about 7 seconds (they say over 5 seconds in the manual). The TV will be turned on and it will have a screen full of status data atop an active TV channel.

    Next, press the SWAP/STOP key on the remote for more than 5 seconds.

    You should be taken to a screen that has " LAMP/FILTER/IIC" as a selectable entity. Press the Action key to select it and move to the next screen of info.

    You'll see a status screen with the number of Service Mode Resets of the Lamp run time (I inadvertently reset my Lamp to 0 hrs after 95 hours of initial operation, and I'll show you how to avoid that in a minute). You'll also see Total Time, which I assume is total TV run time, Lamp Run Time, and Filter Time, all in hours.

    You can backchain to the the prior screens with the Recall button on remote.

    To exit this service mode entirely, you must turn off the TV.

    You can also enter a different service mode menu to control a number of parameters, as I first learned from Doug McDonald at this link >> when I was trying to learn how to perform service mode color adjustments.

    Depress the "Volume Down" button on the set itself while concurrently depressing the "Recall" key on the remote for about seven seconds, and you'll be taken into "Work Mode". At this point, you can press the Action key, and select "Information", where you'll not only see Input mode (as usual) but also Lamp Run Time (but not Filter time or total run time).

    You can enter the more advanced service mode menu by pressing and holding the Volume Down button down on the set itself while concurrently depressing the SWAP/STOP key on the remote for more than five seconds. -- This displayed a Factory Adjust menu, with bunch of settings. See Doug's message for more details. (Do not press Vol Down on the set and PIP/PLAY on remote simultaneously, or you'll reset the Lamp time to 0hrs as I did !)

    Unfortunately, the service manual does not describe all the tweakable settings in the Factory Adjust menu.......

    You must reset the lamp hours in service mode if you have replaced the lamp at about 10000 hours, error will also be triggered

Guess the error is right .. Open the manual and search for it ...
But the air filter cost is around 20 to 30$

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".

Says to clean the air filter

The air filter on this set is on the bottom of the light engine which means you have to remove the light engine form the set to access the filter, i have the guide right from panasonic service manual, no picture as the manual does not have one but here is the info:
Operating with torn or damaged Air Filter may cause damage
to the Projection unit.
Remove the Projection Unit from rear.
The filters are located on the bottom and in new engine
designed the front of the engine.
clean the filters onthe Projection Unit. Gently remove any
accumulated dust from
filter with a vacuum cleaner; use extreme care so as not to
damage or tear the filters.

The engine is a little tricky to get out you really need to be sure each connector removed is inserted and no cable has stress on it when it is being removed, there are no photos of the process just a tech jargon from the service manual.

Hope this helps,

I have a panasonic PT-50LC14. the clean air filter display keeps coming on. I removed the housing for the lamp and cleaned all that area then i removed the back of the tv and cleaned the vents. i watched...

When you take the back off the tv there is a metal brace in the center of the set with pc boards on it , remove the screws and this will swing to the left like a door, take care because some of the wires will have to be unplugged to get it out of the way, then you can see a black plastic box on top of the light engine , remove the cover and you will see the filter remove it and clean it, then replace everyting in reverse order. Hope this helps.

I want to why should air filter clean, what's the benefit of clean air filter and about how many Km should i do this process?

air filter keeps large debris out of engine that could cause failere, and you like to keep it clean as possible to make it easier for the engine to breath .I replaced mine with a K/N lifetime, and just hose it off every other season, but i do alot of city riding so mine does not get as dirty as say a dirt bike filter.

My panasonic pt-44lcx65

The fix for the air filter problem also you are probably getting the on screen message clogged filter also. It can be repaired by relacing the light engine (VERY EXPENSIVE) or remove the light engine and clean the filter much less cost infact none if you know how.
To clean the filter you must remove light engine and you will see at the top a black housing with two screws that must be removed to remove light engine.
A service maual on how to remove light engine is very helpful wich can be ordered on the internet. Any way you want to remove 4 screws from the housing you will then see the filter and 4 more screws to remove in all four corners, remove the screws and then pry the rectangular filter out of the assembly. This may take some effert so be careful. Look at filter through light it will probably be dirty wash with water and blow it out with comprssed air look at it through to insure it is clean then reinstall .Reassemble and you should be good to go.
