Question about Panasonic PT-45LC12 45" Rear Projection HDTV-Ready Television

1 Answer

My PT-45LC12 has picture and fan problems

My PT-45LC12 45 lcd screen shut off with the audio remaining on. I noticed at this point the fan was not running with no front panel fault lights, so I switched the unit off. I unplugged it for 1/2 hour and then tried to turn it on. The green power light flashes but no sound , no picture and no fan operation. Is this typical of a fan failure? Is this an easy fix or should my dealer/repairman be involved?

    Thanks for your help. I'm on my third bulb and I did change just the bulb last time for a big savings. Did you mention class action. My next question is, will a blown bulb shut down the cooling fan?

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 years.
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!

That is the blink code for the lamp ballast. Here is the more complicated explanation from the service manual.

IC2301(pin11) detects the error of LCD Power C.B.A. and Lamp,
then indicates the error when an inner malfunction of LCD Power
C.B.A. occurs, the Lamp voltage becomes more than 130V or
less than 30V, Lamp current becomes more than 5A, or the Lamp is blown

Hope this helps.

PT-45LC12 Problem after startup


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.

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.
