Location of lamp cover on Panasonic 42 - Panasonic Televison & Video

Switch off TV, switch off power, remove plug and wait for 48 hours and retry.
If problem persists, I suggest it is better to refer it to a qualified service
technician, since the back cover has to be opened for investigation/rectification.

first step.remove the screw and lamp door cover at the right side of your TV . After removing the screw and lamp door cover, you will see the lamp cover (it is color black with a handle at the bottom).then turn the knob/handle of the lamp cover on counter clockwise direction to remove it. Then you will see the lamp of your projection TV. Remove the old lamp and replace it with a new one..Make sure that the lamp is properly installed, the return the lamp cover and turn the knob on clockwise direction to lock it up,then return the cover ,screw and its done...

Encompass Parts Distribution has the Part number
for Lamp and Mats Electronics is where to buy Lamp 99.00 1-800-628-1118

Lamp is located under lower front cover as shown in below image, pull that lower front cover and you will see lamp cover tighten with screw.
Remove it and lamp is there.

the lamp cover has a small tab that pushes the lamp switch..the tv will not turn on without..you need it :))

After lamp replacement, make sure that lamp cover is properly fixed on its location and if TV still does not turn On then it is ballast power supply issue, qualified TV tech will fix it.
If you think you can repair ballast supply and have enough knowledge about TV repair, let me know to provide you technical info about that.

If the lamp is actually out - replace it - if the lamp is still working just reset the lamp hours - at 10,000 hours it automatically says that but it is just the lamp time needing a reset.

Sure, I do by myself. Seat on the floor in front of the TV

!st. step: Grasp both side of the silver front cover with your
fingertips and pull it from projection display.

Lamp replacement starts on page 42.

If it has "Popped" then I would expect a rather catastrophic failure, and Lamps don't go "Pop.. they just fail more likely a Capacitor, Resistor, maybe even a semiconductor... so it's off to a reputable repairman get a "quote" and proceed from there.
