    I cleaned my fans (all 3 of them) and the message still appears to "clean air filter". I am waiting overnight with the tv unplugged to do a hard reset and will see sometime tomorrow if the problem persists. Does anyone know how to reset the air filter message. Also, my temp light flashes 5 times and then is off for 5 seconds which indicates a "malfunction" according to the manual and says the tv requires servicing. I liv 2 1/2 hours away from the nearest service shop for pans. I need a fix it myself manual. Any help is greatly appreciated.

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".

On my pt-50lc14 hdtv my screen is stuck on this message, 5v eeprom), 3.3v (gc2), tv-factory mode


Have you tried any of the reset commands?
Try these....please let me know the result:

Method 1
1. Unit power must be ON and unit must be in STOP mode.
2. Press and hold [CH UP] and [CH DOWN] ON THE UNIT for over five seconds. The unit will turn off.
3. Press [DVD POWER] to turn the unit on.

Method 2
1. Press [STOP, TUNE MODE] on the main unit and [>10] on the remote control at the same time for about 3 seconds until the message "Initialized" disappears from the television screen.
2. Turn the unit off and on again.

Method 3
While the unit is off, press and hold [VOLUME +], [OPEN/CLOSE] and [POWER] on the main unit at the same time for more than 5 seconds.

Method 4
While the main unit is on, press [POWER] on the main unit for more than 4 sec. (All the indicators will blink twice when the main unit is reset.)

Another possibility is to unplug the power cord......wait 30 minutes and plug it back in, possibly repeating the steps above. (Method 1 should reset the unit but maybe trying each of them may be necessary until it is reset.

The message appears to be one that displays when the unit is in a setup mode.

Thank you for your reply.

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.

Message says airfow blocked, turns on for about a minute then shuts off


1. Remove the air intake filters on your DLP projector. As explained by InFocus, a manufacturer of LCD and DLP projectors, each DLP model will house the air filters in a different location. However, for most DLP projector products, the filters are accessible by unclipping a simple plastic latch.

2. Wipe the air filters with a small cloth dipped in rubbing alcohol.

3. Blow compressed air into the unit's vents. This will force some internal dust out of the DLP projector, but you may still need to open up the unit for additional dust removal.

4. Unsnap the main cover from your DLP projector. Because DLP projectors need periodic lamp replacement, the main cover is rarely secured with screws or bolts. However, if the DLP projector's cover does not snap off, then you'll want to inspect the unit for possible screws or an alternate release latch.

5. Reach in and remove visible dust globs with a paper towel. Be careful to avoid touching the lens, as fingerprint smudges can diminish DLP projector image quality. If you accidentally smudge the lens while picking out dust blobs, wipe the lens with a dry, lint-free microfiber cloth.

6. Spray compressed air into your DLP projector to remove any lingering dust particles.

7. Close up the projector and reattach the filters.

OSD Message Panasonic PT-50LC14 Air Filter Needs Cleaning


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.
