My PT56LCZ70 takes several minutes to warm up

I had the original LIFI lamp replaced in my PT56LCZ70 after two years and under the extended three year warranty. It worked fine for a month or so but now it takes a few minutes for the picture to appear while the green light flashes. (The picture will appear mementarily several times before staying on) Does this mean the replacement lamp is bad or just something I have to live with?

Lamp or Power issue Panasonic PT56lcz70


I would think that the fact that when you held the power button in for a long time that would give you a hint! If the power button is making a poor contact there will be a small surge of power and some parts of the internal circuits will respond(indicator lights, for example). Try REPLACING THE ON/OFF BUTTON.

My panasonic lifi tv starts flashing green then the red light flashes red all the time now.


If the light is flashing 2x and pausing and repeating you probably need a new lamp.Panasonic has extended the warranty on the labor for the lam p to 3 years due to difficult replacement.Call Panasonic customer service and they will refer you to the nearest service center.The lamp itself is covered for 5 years.

Tv stoped working - LIFI PT56LCZ70


This unit has a very complicated bulb replacement procedure. You would be much better off if you contact a panasonic service center and have them replace it. Bulb assy is pretty expensive as well. The part # is LFS4000PA1EB but you will have to go to panasonic to get it. Good luck. Thanks

The LCD light (green) flashes for like 6 times and then the pictu


even though the lamp light is not flashing I would think it is the lamp getting weak for some reason the Sony's do that.

Sony grand wega KDF-55wf655 TV goes into flashing green mode


I was having the same problem. I am no expert, but what I read on-line is that it was likely the lamp needing replaced, that the lamp toward the end of its life will flicker and cause the TV to "reboot". I had no Red Lamp replacement light, so I wondered if that was really the problem. But, I bought a replacement lamp for $110 plus shipping, and replaced it last night - TV is working great now. I would try replacing the lamp on yours first yourself (if the lamp is older than 2 yrs), then if that does not work, contact a service person. Don't have a service person replace it, because I have heard many people say they paid $400 for a replacement lamp service, and I did it for under $140 with overnight shipping charge for the new lamp. My original lamp lasted 4 years, so I was lucky to not have this problem sooner.

I have a panasonic television that will not turn on, it sounds like it wants to. the fan is clean and all cords are plugged in correctly.


Your "forever" LiFi lamp has gone out. Done three of these this month. Panasonic is extending the warranty on these lamps to 5 years for the part and 2 years for the labor - better call panasonic quick.
