Re: TV Powers off

I think the lamp cover switch is acting backwards. Should quit when the door is off, and only work when the door is on. Look closely at the cover switch and see if it is messed up somehow.

The lamp light is blinking once every 5 seconds. The manual says that " Lamp will not light or light is abnormal"


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.

WERE exactly is the Lamp in my T.V ?

You must remove the plastic cover from the front and just left of center there is a panel covering the lamp with a single screw. Under that the lamp is also held in with a single screw. Pull on the handle firmly to remove lamp. Replace with TY-LA1000 bulb.

TV shut off and cannot turn back on

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: Good luck and God bless you!

Panasonic PT50LC14 Power issue

We have a PT-50LC14. We replaced the lamp 6 months ago with a TY-LA1000 bulb we bought from a company online (not directly from Panasonic) and it worked for 6 months. Then the TV started turning off on it's own...sometimes it would not come back on for an hour or so. We called the lamp company and we luckily had 1 day left on our 6 month warranty!! They sent us a replacement bulb and the TV would never power on. It would try to power up, but the bulb would never ignite. The power light would flash and then the lamp light would flash every 5 seconds. I had a friend that has the same type of TV and she ordered her bulb directly from Panasonic. I borrowed her lamp and it powered right up. We then called the online company and they sent us yet another replacement bulb, and I tried it today and it works. It seems like these TVs are very particular about the type of bulb used. Next time, we will be ordering ours directly from Panasonic and just paying the extra $100. We have been without our big screen for 2 very long months! I had called a local tv repair shop, called Panasonic directly, and read through countless internet forums, and I thought we were going to have to replace the ballast or get a ballast repair kit and start messing with the circuit board.
