Top 10 Panasonic PT-50LC13 50" Rear Projection HDTV Questions & Answers

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.

i'm on my 3rd bulb in 5 yrs. i hate this tv. this time my bulb light didn't come on. instead the power light flashed green fast then went to red flashing after. i took out the bulb and it's blown!

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

This proceedure should work for your model to reset the lamp meter.
Lamp Time Reset Procedure:
Be sure to reset the Lamp time to "0" after replacing the new
Lamp.
1. Plug in the AC Cord, and turn on the power by pressing the
POWER button.
2. Press and hold the VOLUME DOWN button on the unit and
the SPLIT key on the remote together for over 5 seconds
in power on condition.
When the reset is finished, the display will indicate that the lamp hrs have been reset to 0 and the LAMP LED goes out.

My Panasonic PT-50LC13 when turned on has a green light for a few seconds you can hear the fans turn on and then you have a yellow/amber light that starts to blink 8 times i have replaced the bulb and the door is closed any ideas?

The light engine may be dirty with dust, the polarizer filter burned, or the LCD elements burned.

As a last-ditch effort, the light engine can be taken apart and carefully cleaned using compressed air.

You need to have your Panasonic remote.
1. Make sure the power cord is plugged into a properly grounded outlet and turn on the set with the power button on the projection unit or the remote control.

2. While holding down the (VOL -) key on the projection unit press the PIP or SPLIT key at the same time. Hold it for longer than 5 Seconds. The PIP or SPLIT key is model specific:

PIP for Models:
PT-50LC13/PT-60LC13/PT-50LCX63/
PT-60LCX63/PT-43LCX64/
PT-50LCX64/PT-60LCX64

SPLIT for Models:
PT-43LC14/PT-50LC14/PT-60LC14



3. When the unit resets the lamp timer it will display a screen on the TV indicating it was reset to zero. You press recall on the remote to exit.

I feel bad for you having such problems with the vendor and the technician too.
The location of that filter could be a small window in the back cover itself. could be a plastic window to the left side of the unit and is only a piece of plastic poliuretane kind of black sponge about 5 by 3 inches size .
What im interested telling you about the shut down condition and is maybe even most important than where is the air filter (who is one of the more than ten posibilities why the tv goes to shut down.
Note:
if the air filter is totally obstructed i would give one of ten probabities of suspicious why the tv shuts down:
first because the tv's air duct is not really isolated. The fan can eat air by any side of the air filter base as i said if the filter is totally obstructing which is really extreme. besides maybe the other 2 fans could help to cool down the unit in that case scenario. In my experience Most time the air filter holds tons of dust but is not totally obstructing the air passing, and really some other problems are in the set.

This is the really critical to know: if any of those fans stopped or maybe any sensor is overheated or the lamp is coming to dead or who knows.. a diagnosis is needed for this symptom really common in DLP technology.

Check partstore.com to find the kit. The kit part number is LSUC0022.

Follow this procedure to replace the lamp:

1. Turn off the power on the main unit. Wait several minutes, then unplug
the power cord.
(The cooling fan will continue to operate for about two minutes after
turning the power off.)

2. Wait at least 30 minutes after unplugging the power cord to allow the
lamp to cool down before replacing it. To avoid being burned, do not
touch the lamp receptacle once the lamp has been removed.

3. Take the new lamp out of the box.
Do not touch the glass portion of the new lamp.

✍ Do not shake the lamp. Vibration can damage the lamp or shorten
its life.
✍ Avoid touching the front glass of a new lamp or the glass of the
lamp receptacle. This may reduce picture quality or lamp life.

4. Loosen the screws on the rear side panel.


5. Remove the front panel.


6. Pull out the lamp.
Loosen the right screw on the cover with a coin or similar object.


Remove the screw from the lamp cover. Pull down the cover toward you.



Unscrew the lamp and pull out the lamp horizontally.



✍ The lamp is very hot immediately after use. Never touch the glass
portion of the lamp or the surrounding parts.
✍ After it has cooled, place the used lamp into the empty box of the
replacement lamp. Never put the used lamp into a plastic bag.

7. Place the new lamp into its place, then tighten the screw.
Mount the new lamp securely. Failure to mount correctly may cause a
fire or the screen to go dark.




Push the cover back on. Make sure that the hole on the cover aligns with
the hole on the unit. Reattach the lamp cover by tightening the screw.



✍ If the lamp cover screw is inserted incorrectly, the lamp may not
operate properly. In such a case, remove the screw, insert it
correctly and then tighten the screw completely
✍ If the lamp cover is not reattached securely, the self-diagnostic
function may be triggered and the POWER indicator flashes three
times

8. Reattach the front panel securely.




9. Tightly screw the side panel in its place.

That is it. Thank you.
