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".

Soulvisitor has it right. 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. Thank you Soulvistor you saved us at least $100.00

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.

Good luck

Clean filter message reset


the filter will need to be cleaned and if the set still shuts down then I would suspect the fan may need to be cleaned and possibly replaced.

Mitsubishi HC900 Projector shuts down after 5 minutes.


You have 1 of 2 possible problems.

(1) You need a new lamp.

(2) You have an overheating problem.

Just a quick couple of notes about your projector. It is a DLP projector (not LCD) and as such the machine as no air filters to clean. It does have air intake and air exhaust grilles, but no air filters to clean. This next part comes directly from the owner' manual for your projector:

When the lamp operation time exceeds 2000 hours*1 *2, the projector automatically shuts off and can’t be used until the lamp is replaced and the lamp operation time is reset.

Your machine is designed to give visual warning messages at 1500 hours used, and 1900 hours used. Did you see any visual warning about lamp life over the past few months?

If you were experiencing an overheating problem, a "TEMPERATURE!!" message would flash up on the screen just before the unit shuts down. If there is no warning, you don't have a heat problem.

If you have a replacement lamp available, install it and reset the lmap hours according to your user manual. If you don't have the manual, google it on the web (it available).

Projector Reset


Hi Here is the info for you :: Caring For The Air Filter The air filter should be cleaned about every 100 hours. If the indicators or a message prompts you to clean the air filter, clean the air filter as soon as possible. If the soiling will not come off the air filter, or it becomes damaged, then it needs to be replaced. Please replace the air filter as soon as possible. memoWhen you replace the lamp, please replace also the air filter. Turn off the projector, and unplug the power cord. Allow the lamp bulb to cool for at least 45 minutes. Apply a vacuum cleaner to the top of the filter cover and the air filter to clean. If the soiling will not come off the air filter, or it becomes damaged, it needs to be replaced. If the air filter needs to be replaced, contact your dealer to prepare a new air filter. Tell the dealer your air filter type. Turn on the projector power, and reset the filter timer. (1) While the projector running, press the MENU button to open the menu. (2) Choose the ?OPTION? on the menu using the / button, then press the button or ENTER button. (3) Choose the ?FILTER TIME? using the / button, then press and hold theRESET button for 3 seconds. (4) Choose the ?RESET? using the button. memo Incorrectly resetting of the filter timer (resetting without replacement, or neglect of resetting after replacement) will result in incorrect message functions.
