Panasonic 50" LCD TV PT-50LC13

I did the following '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)"

Will in the service screen I selected the number of hours of the lamp with the down arrows and the action buttons. Then I simply pressed and held the "down volume button" on the remote until the number of hours was 0. Then I turned the TV off, then back on and the message was gone. This worked for me.

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.

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.......

I just fixed my problem. I was getting the lamp needs to be replaced window so I proceeded to hold down the low volume key on the tv while holding the tv/video key on the remote. I waited a few seconds and let go when the green power button on the tv comes on. Once the tv is on you see all this weird data. Scroll down to the lamp hour section and hold down the low volume key on the front of the tv while using the down arrow on the remote to bring the lamp number to 0. Once this is zero then turn off then turn on again and you should see no more message.

Well you would need to pull back off and take light engine out to get to filters. did you also reset lamp timer that message will also show up if you did not reset after about 10,000 hours
