Panasonic Plasma TC-P65ZT60 and TC-P65ZT60 usage hours?

That's so old that it's probably almost free. Just buy it and take a chance. I see them at the Goodwill all of the time.  

I have a Panasonic plasma a little newer but have not checked the usage hours, still looks great. Plasmas put out quite a bit of heat. If it were me I’d buy an OLED and be done with it

Unless it’s free, it’s not worth it. I had the smaller version of this one and once it burns out (and knowing the hours won’t predict when it will), it’s not worth repairing. 

My Panasonic plasma burned out after 5 short years.  We only used the TV in the evening for a couple of hours l at most.  Bought a Samsung LED TV (OLED wasn’t invented yet) still going strong. Do not waste money on 16 year old tech. 

I had a Panasonic plasma years ago. They actually make good space heaters.

I have the TC-P65VT60 for over ten years and never have any issues with it. I assume it will die one day soon. The picture is outstanding. I don’t think status 4 has the information you are looking for. Here is what mine shows:

Status 4   C9999 - 00000

Status 5   00000 - 10000

Still using the ZT65 Panasonic plasma as the benchmark for high end TV's. What does that tell you?
