Panasonic pt-50lc13 air filter location

I need to clean the air filter.  I can't find it in the front, next to the bulb compartment, or in the back anywhere.  Can you please tell me where it is?

Re: panasonic pt-50lc13 air filter location

It is in the front on the left of the bulb compartment. It is as easy as removing two screws using lots of DAMP Q tips and having some patience. Keep carefully swabbing top and underside filter until clean, then lightly and very carefully vacuum with a home vac do not use a shop vac!
Leave TV unplugged with cover off as long as you can I would say a few hours or overnight and then plug in. If the filter is clean and you still get the error message there are other posts here that explain how to go into service mode and reset.
You do not need to spend hundreds of dollars on a "Panasonic" technician who has "done it before". You can dooooo it!!

Re: panasonic pt-50lc13 air filter location

I Did remove the front panel (2 screws),next to the lamp panel. Did the Q-tip/alcohol then vacuum trick numerous times on both filters, though the large one that is underneath is almost impossible to get to. First time I did it, the TV worked fine for about six weeks. Then the message came back. So, I went back in and cleaned them again, then the TV would work for a while (few weeks, then just a few days after the 3rd and 4th try. I then saw online that there was a 3rd filter through the rear panel. So I called a TV technician that charged me $125.00, for him to do the exact same thing I had just done, and tell me that there was no such 3rd filter. So after suffering this rip off, I decide to remove the back cover myself, then removed a few more screws and assemblies ( as I found explained on some other blog) and there is that 3rd filter that I carefully pulled out. It was very dirty. So I cleaned it (Vacuum, blow gun, alcohol). Then I put the whole thing back together, then the TV worked for another month. Then comes that filter message again! So I went back in the front panel, then carefully unglued the small filter and looked at it in the light, it still was very dirty, so I cleaned it really good following the usual procedure, then glued it back on, then the TV worked for another couple of weeks. Then I got mad and got back in the front panel then managed to remove the large filter using a long skinny blade. I looked at it in the light and it was very dirty. Now I have no way to put it back in because of restricted access so I decide to leave it out! The TV has been working fine so far (2 weeks), but I have little hope for its future. This is a hard lesson learned. I though I followed procedure to the textbook to clean those filters, but something tells me that this "cleaning solution" only buys you little time. This also tells me that the only way to repair this the right way is to replace those filters with new ones, which probably means replace the whole projection unit as far as getting the parts from Panasonic!

This set has two filters that need vacuming. The one under the light engine is the usual culprit. Call a Panasonic Authorized service company that has done this before.

Panasonic pt 50lc13 Ballast update done Bulb blew out just replaced and now the amber ( yellow flashes twice ) every 5 seconds how can i check the door lamp switch? is it just an open closed switch? thanks...

The door switch is in the front. The switch is triggered when you put the lamp door cover back on. It is a switch thats spring loaded so when you put the lamp door back on it automatically presses the switch.
If you have any other questions please feel free to ask.

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

I have a Panasonic Model PT-50LC13 flat TV. Was working when got it brought it home, it is used and now when I go to turn it on --- we get a green light then a flash of 5 yellows blinks then no light for...

This tv has 3 indicator lights on front, Power, Lamp and Temp
I assume Temp light is blinking 5 times after every 5 seconds, if that is correct then it is problem of clogged air filter located in light engine that need to be cleaned.
Below is an image of light engine and air filters locations are marked with red circle, it is job of professional to fix this issue because complete light engine need to be take out from tv cabinet.
Hope these info will help you, let me know if you have additional question or need service manual copy if you want to repair tv by yourself.

Panasonic TV pt-50lc13 bulb replacement

Take the bulb out, there should be a access panel in the front, power the set on,(be sure to have the lamp door closed) if you hear a rapid ticking noise from the set, the Ballast is trying to fire the lamp, this is a good indication that the set is functional but the lamp needs to be replaced. If not, the ballast is not getting the voltage needed to start the lamp.

Panasonic model# PT-50LC13

It very well could be the ballast. I unfortunately have this tv and keep extra bulbs because they go out about once a year. Last time when I replaced the bulb the tv blinked and the red lamp light flashed like it does when the bulb is bad. Ballast repair kit fixed it up. This is certainly a design issue but you'll get no help from Panasonic. If tv comes on the goes out after a while, clean the fan filter.

Unplug the unit! Pull off the access silver panel from the front of the tv. there are 2 sma ll access panels on the front behind the silver panel. The one on the left, allows you to change the bulb, one screw to remove, Just to the right of it there is a second one. This has 2 small screws to remove to access the opening. Once you take this small cover off, you will see the fan compartment. On the top of it on the left side is one small filter, mine was pretty clean. The bear is the one on the bottom, that you can only see the edges, but there is a small opening on the bottom. It looks like it is suspended in mid air. Take a cue tip and clean the underside! I slightly wet my cue tip and it worked fine. I tried to remove the fan compartment, but it would not come out and I did not want to force and break it. Remember to unplug the unit first. After I used the cuetip on the filter, I have a small vacuum and cleaned everything carefully. I had heard to leave it unplugged for about two hours to let it clear after I reassembled the covers. I turned on the set and the message was gone and has never come back. I did not have to reset and worked for me. That was it for mine and it is working fine
