There are indeed 2 air filters on the light engine. To clean these, it is necessary to open up the television's back lower panel, remove an electrical component, then slide out the projection unit (you must be very careful - this is over $600 to replace if you break it). The air filters are pretty easy to clean...I used gentle strokes from a soft bristle hobby paintbrush and blowing (I wouldn't recommend using a can of compressed air for this...these filters are somewhat fragile). Dust out the rest of the unit pretty good (use EXTREME caution when doing this). Then put everything back together, and then you have to go through the re-alignment procedure. You can obtain the technical service manual on the Internet...sorry, but I can't help you find it...I am not sure about the legal/copyright ramifications of distributing the manual w/o Panasonic's permission...but its out there...Google is your friend. I would NOT attempt this repair without this manual...it contains crucial diagrams, and "gotcha" warnings (like what order to tighten screws for example). This isn't a hard repair if you just take the time to prepare, move slowly and methodically, and don't be in a rush. Good Luck!

I'm using whirlpool mastermind chrome split ac.. clean filter light started blinking so i cleaned and replaced the filters but still CLEAN FILTER light is blinking. please give a solution


If you didn't turn the Master ON/OFF Switch to OFF, before removing the filter. That is the problem. To clear the error message. Turn the Master ON/OFF Switch to OFF, unplug the unit, remove the filter and reinstall it. Wait 10 minutes, plug the unit back in, turn the Master ON/OFF Switch to ON. The controls should have reset themselves and the clean filter light should not appear.

Hope this helped you solve the problem. Please let me know. Thanks.

My dryer keeps saying Lint Filter Problems and cutting off however the lint filter is clean. Because of this issue I the dryer will not stay on long enough to actually dry the clothes. It continuously...


try two things. first, run it empty without the lint filter installed. if it gives you the same error message, install the filter, but disconnect the flexible duct connected to the back of the dryer. try it again. if it still wont work, you will have to get it serviced and cleaned out. if it works with the ducting removed from the back, your dryer duct is clogged up. check your yellow pages for dryer duct cleaning. The lint filter error message is just your machines way of saying it is not getting enough air flow. It can be caused by a clogged duct also.

There is a side panel where the Lamp is located and held on by a screw or two.
Open that compartment and vacuum out all dust. Also any fans should also be cleaned.

I had the same problem and the stupid tv would shut off after 1 minute. We opened the silver front panel , took the bulb out cleaned it, took the cover off the grey box to the right and very carefully vaccumed the filter and wiped it off with a microfiber cloth. It works great now!!! Make sure you unplug your tv before messing with it.
