Question about Panasonic PT-50LC13 50" Rear Projection HDTV
Internal engine reports an air filter cleaning needed and to call a tech. Is there a solution that I could do. After message appears, the tv shuts itself off. Just replaced the bulb to try to solve problem, it did not help. Was told to unplug the tv for 2 hours and it should reset, does not help!
Air Filter Cleaning for Panasonic PT-43LCX64 PT-50LCX64 PT-60LCX64
OK, I purchased the service manual which explains it pretty good. However it is pretty complex with about 45 screws to be removed so if your going to attempt it buy the manual (mine cost $14.99). There are 3 filters, one at the back and two at the front. Once the procedure is completed there is nothing else to do other than switch it on. There are no timers to reset in the software like some other models. So there must either be an airflow sensor or a temperature sensor. I'll look at the service manual in more depth when I have a chance.
I do have a request for someone. The filter at the rear was pretty clean as was the one on the top part of the projector assembly. The one at the bottom of the assembly was dirty. I think that it might be possible to clean the front filters far more easily. So if anyome wants to try it here is a possible solution.
Remove the front panel (silver). Undo the 2 screws on the cover of the projector housing (not the one that gives you access to the lamp. Remove the cover. Carefully vacuum the top dark grey foam filter on the left side of the pojector unit. Next vacuum the bottom of the unit. That's were the main and dirty filter was. You can't really get to it but I'm hoping you might just get enough off to get it working. The TV senses if its clean enough so there's nothing to loose by seeing if this shortcut works. Once the error comes back I will try it myself.

Remove silver panel on front marked HDTV and BBE
Open bulb compartment
On the right side of the bulb compartment is the filter compartment
Remove filter and clean
Every 400hours it will prompt to do so. Check lamp timer if you have changed bulb and reset as instructed below
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 >> http://www.avsforum.com/avs-vb/show...hlight=pt40lc12 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.......
