Question about Panasonic PT-56LCZ70 56" HDTV
I have the same problem. The local service center automatically asked if this was a LIFI after saying the word Panasonic. Not a good feeling, but at least I'm still under the LIMITED warranty. I'll go with another brand TV next time.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

LiFi lamp has died. Get on this quick as Panasonic has increased the warranty on this bulb to 5 years parts and 2 years labor. Call panasonic right away.

Just to be sure, I looked at your Model Number and found a PT-56LCX70.
I usually order my parts from Andrews Electronics in California, they will have the OEM components that you will need.
Their site is http://www.andrewselectronics.com/welcome.aspx
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about the different types of IC’s that are available.
The part number that I was able to find was LFS4000PA1EB.
But I would contact Panasonic about this problem, they have an 18 month warranty on the lamp product.
I hope this information allows you to resolve this issue.
If you need further assistance please comment to this post and I will try to help you further.
Thanks for using FixYa
