I have a pt-45lc12 that is about four years old. when I try to start it up, the green light will flash for about 10 seconds, then switch back to red without the picture coming up. you can hear the fan start up as well, and a faint clicking sound. I never got a message that it was time to change the bulb, and I cleaned the filter regularly.
any suggestions as to what might be the problem?

Re: PT-45LC12 wont power up
You have a bad lamp. The "clicking" sound you hear is the ballast (lamp power supply) attempting to start the lamp. The warning on Panasonics that comes up on screen does so when the life expectancy of the lamp is approaching. Otherwise your "clicking" sound and the red light on front are saying bad lamp. When you replace the lamp remeber to follow the instruction that Panasinc provides with the new lamp on restetting the lamp timer. This is usually done with the volume down on the TV and the PIP button on the remote.

Ballast Board ,it is what turns Lamp on! Call Encompass Parts for Part or look them up online they have website. Call 1-800-638-3328 Ok I looked it up Part# is LSEB3062A1 which showed No Longer avaliable,So try UED 1-800-648-6657 and Look on E-Bay under Electronics For Ballast Board.
When the lamp flashes 4 times this is what the error code means IC 2301 pin 11 has detected an LCD error which is caused by an error in the LCD power CBA. which means the lamp voltage has become more than 130 volts or less than 30 volts. Or the lamp current is more than 5 amps, or the lamp is cracked. Its one of thos 3 reasons that will make the lamp indicator blink 4 times. Hope this helps. If you need the service manual for this model you can get one emailed to you from the following link. http://servicemanuals.vstore.ca/
More like lamp failure. Could be other things of course but
start with the lamp cause it will need it anyway if has been a couple
Projection TV makers charge an arm and a leg for their replacement
lamps. They make it easy to do but as a result the custom lamp
assy is expensive. The trick is to just buy the bulb for your
model TV from any number of us aftermarket sources at a fraction of the
lamp price and install it in the old lamp yourself. really
easy. Some models are real bulb hogs though. Look them up
on the net (include the word complaint or repair) before you buy, or
you might be sorry. Many class action lawsuits out there - even
against some of the name brand makers.
Hope ya fix it!
