HI,

Panasonic PT50LC13 lamp indicator blinks to tell you the lamp is faulty.

You need to replace the bulb or TY-LA1000 lamp assembly. This link displays all Panasonic TV Lamps and TV Bulbs. This page shows Panasonic lamp location and How to Replace TYLA1000 bulb. TY-LA1000 Bulb Replacement requires the use of a long Philips Screwdriver to reach screws within the lamp cage.

Unplug AC power before removing the lamp and re-install all doors, etc, correctly before starting the TV. Vacuum any visible dust or lint from air vents and lamp area. Do not used forced air to blow out dust, big problems may result.

The user's manual has a description of what the Blinking LED indicators mean.

If your tv is around 2-4 yrs or used 6000-8000 hrs,never replaced the lamp before it could be time to replace it.The other most common failure is the board that powers the lamp,which is called the ballast.When its bad it will make a clicking sound or like wanting to turn on.The part # for your lamp is TYLA1000 you can find it here:http://www.discount-merchant.com/Panasonic-TY-LA1000-Lamp-DLP-TV-bare-lamp-p/panasonic-ty-la1000-lamp.htm Good luck and God bless you!

Model PT-50LC13?
Replace the lamp .
There is instructions in the owners manual.
Panasonic P/N : TY-LA1000 $150.00

For the low price of $9.99 per month I will be glad to share the solution.

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.

sounds like the lamp faceplate is not screwed back in properly

Your service manual on page 82 steps you through decoding the blinking
1) there are two lights on the front near the reciever of the remote signals (Temp indicator and Lamp Indicator)
2) If the Temp indicator is on then they recommend you contact a service center
3) If the Lamp indicator is on and the power light stays on (no blinking) then you need to replace the lamp. Otherwise it says to contact the service center.
4) Counting blinks with the lamp indicator (1 every 5sec - lamp will not light or is abnormal, 2 every 5sec - lamp voltage is abnormal, 3 every 5sec - lamp temp is too high, 4 every 5sec - other error)

not really, just be careful about getting finger prints on the lamp as the oils from your fingers will shorten the lifespan of the lamp.
