How do I replace the lamp LFS4000PA1 on a Panasonic PT-56LCX70-K TV

Hello , my name is Jack
Perhaps I can help you with this problem but first i would have a few questions;

Do you actually have a new lamp unit in hand ?


This is the lamp unit;

Hello ?

Can you see my reply above ?

Customer: replied 2 years ago.

Yes I have a new lamp LFS4000PA1

O.k then , reason for asking is that usually this lamp had to be replaced by a Panasonic ASC (authorized service center) or you needed permission to buy this lamp.


Perhaps things have changed.


What I can do is to upload the procedure to replace the lamp from the service manual.

Although I must say that this lamp was not user replaceable and it can be tricky.


Be back shortly with that procedure.

Sorry it took a while , had to split it in 2 parts

Here is the first part , click on the link here "CLICK ME"

And here is part 2 "CLICK ME"


Give them a minute to open and you can then save them to file and/or print them .

There are 18 pages in all.


You will also see that the optical block has to come out to replace the lamp , no need to remove the front of the tv.


Hope this help and please take the time to rate my answer if that does the trick , otherwise do not rate at all , just let me know and we`ll see what can be done.
Note that you can reach me here at any time after rating if you have questions.

Am I missing the reassembly instructions? The last page I received was page 42. This contains all the instructions for removing the lamp but no instructions on reassembling everything.

Actually where it says re-assembly on page 42 , that is for the "

Reassembly Note for Lamp Shield Case Ass’y: "


The re-assembly is the reverse procedure you just performed.


There is no re-assembly procedure per say in the manual

thank you


Customer: replied 2 years ago.

the TV works good now. I gave you an excellent service rating.

Thanks for your assistance.


Glad to hear that.


By the way , if you did receive a reminder/message about rating , then it was sent by the website , not me.

Looks like the system has been doing that lately , just ignore future message about rating.


Thank you and happy tv :)
