Panasonic Projection TV Lamp Timer Reset
Your lamp will probably last a lot longer than the TV thinks it should. This procedure will reset the lamp timer so you don't have to look at that annoying message every time you turn your tv on. Remember that the "lamp" indicator light on the lower left of the set will stay on until the lamp is actually replaced. I had to buy a replacement lamp to get this information, could not find it anywhere for these model numbers.
Press the volume down button on the projection display and hold down the zero button on the remote control at the same time for more than 5 seconds. When the reset procedure is complete, a message will display that the lamp timer was reset to zero.
This procedure will work for Panasonic models: PT-52LCX66 , PT-56LCX66 , PT-61LCX66 , PT-52LCX16 , PT-56LCX16 , PT-61LCX16

Hi,

The most common cause of Panasonic Rear Projection LCD TVs not starting is bulb failure. The PT-60LC13 users manual gives some help in translating the LEDs on the front of the TV.

If the TV worked normally for a period of time (months or years) and won't start, the most likely cause is bulb failure. There is no way to measure the bulb, sometimes the bulb is visibly damaged when it fails. Remove the Lamp Assembly and look at the bulb.

If there was an On-Screen Lamp Replace warning and TV won't start, bulb has failed.

The first step with all Panasonic Rear Projection TV "No Picture" problems is bulb replacement. If that does not remedy the problem, get a technician, there are no user serviceable parts. Guessing if the ballast, power supply, controller board or optical engine is faulty is not practical.

The Panasonic Lamp Gallery shows all Panasonic models and Lamp Numbers. There is also a link to Panasonic DIY bulb and lamp replacement.

convergence failure. You can get the repair kit for your model which contains the parts and the CD with instructions at the following link. http://servicemanuals.vstore.ca/product_info.php/pName/panasonic-projection-tv-convergence-repair-kit-1/cName/convergence-repair-kits

It's one of two things, a bad chipset, or bad lamp. 200-250 repair. Hope this helps

My Panasonic has exactly the same problem. The repair man just came in and said that the convergence and resistor burned under heat and have to be replaced. Will cost $400.

All different brand of PTV has there way of excisting out of the service mode, panasonic don't list it, very hard to do, turn tv off then you see.

What about Bob

turn the TV power on the projection display or remote control.while pressing the volume button on the projection display hold down the PIP or split button on the remote control simultaneoulsy for more than 5 seconds.
