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

1 Answer

TV lamp, sound.... don't come on...

Green light comes on and blinks. No lamp and fan by filter comes on. The fan by the lamp does come on. Changed lamp, checked all fuses and transformer and all seem OK. Where is the balast located and how can it be checked? Should I be looking elsewhere for this problem.

The balast has a plug going directly to the lamp. There is also a thermal fuse coming off of the balast that lies above the lamp housing. Check for continuity. If open, replace.

Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.
For example, 3 flashes, then 7 flashes = 37.
Here are the error codes, and the corresponding problem:
12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected

Ok so I changed the lamp in my wd 62327 and now I have no picture or sound. The lamp light blinks the turns red and the whole tv shuts off. Any suggestions? Someone said to reset it but don't know...


If issue was different from before you replaced the lamp---remove lamp cartridge and look to see the place where it plugs in that the 2 pin socket the lamp connects to is not out of position or got bent when you replaced the lamp.

A reset if it has it is a recessed tiny button on front control strip up front--those when plugged in will blink (green) for 70 seconds and go out and then set can be turned on.

General: the set will shut down for a lot of reasons-----from a lot of dust inside on the fans (this one should have 3 fans) and I have seen it not allow the set to come up and then shut down---the sets intake a lot of dust thru the front and if the fans get coated the set will detect one or more are not turning at the correct speed, turn the lamp off and shut the set down.

Let me know what you find and give me more information if possible.

Just changed the lamp and the "status" light is


you must install the lamp door after lamp replacement to get the "yellow" blinking to stop. if the status is blinking red then you may be having a fan failure internal to the tv. also make sure that the side filter door is installed and secure

Tv will come on but shuts itself back off


Sounds like it just needs a new lamp.
The way to tell is the lights in front:
green blinking as TV reboots = bad lamp
red three blinks = door switch
red four blinks = bad fan
6 or 9 blinks = bad thermal fuse

Hi,
TV needs lamp replacement as existing lamp got weak or has been reached to end of its working life, please note that lamp is not dead or broken so that is why lamp lit is not lit at tv front.
Hope these info will help you.
Thanks.

Green Timer lights blinks for about 10 sec. Then Lamp light, then nothing


Definitely sounds like a power supply problem. Check with your local TV repair/service center about getting it repaired or replaced.
