Re: Need advice on buying used Plasma

I'd probably not bother with a 5 year old plasma, but that's just me.

You can look through the Amazon negative reviews to see what the common issues on this TV are:

Also, check for burn-in:

Are you going to use it for 3D? Does it come with working shutter glasses?

Re: Need advice on buying used Plasma

Panasonic stopped making plasmas in 2013. So i dont have nuch of choice on a 4 or 5 year old plasma. I think they are the best tv's still made today.

I probably wont use it for 3d. The tv also does not come with the glasses.

Some used panasonic plasmas are going alot of money...

Have you looked at OLED TVs?

I have a LG 4K HDR OLED with passive 3D. OLED has the same "deep blacks" as plasma, but are lighter and thinner. I feel that HDR is a big boost in image quality too.

Here's some articles and a thread comparing OLED and plasma tech, although since they're from a few years ago OLED has only improved since then.

The plasmas have the best refresh rate. I dont think the oled come even close to that..

The "600Mhz" refresh rates of plasma screens is mostly BS; It relates to how plasmas adjust the brightness of their pixels, not how many frames per second they show:
https://www.cnet.com/news/what-is-600hz/

There is still some BS regarding refresh rates with 4K TVs though:
https://www.cnet.com/news/ultra-hd-4k-tv-refresh-rates/

Basically, if you get an OLED with a true 120hz refresh rate, the motion blur should be on par with your plasma, and may be better since the plasma is likely only updating the image at 60hz.

Edit: This review of the Panasonic TC-PGT50 mentions that its "true" refresh rate, i.e. how often it updates the image, is 60hz.

Re: Need advice on buying used Plasma

So i read those articles and they are very interesting. So i looked up oled tv's.. the cheapest 65" tv i can find is 3k. Big difference then the $500 i can get the plasma for. I currently have 2 plasmas now.. one of them is about 14 years old(50")and the other is about 6 years old (60"). Both work perfectly. The only thing that concerns me is this burn in.. I have never had a burn in problem... are these newer 50 and 60 series tv'd more prone to burn in?

Well sure, $500 for a used 65" plasma is a pretty good deal, but I wouldn't call that "alot of money."

I doubt it, but you never know how the previous owner was using it. You asked for things to look out for, so I mentioned burn in as a thing to check for.

Sure that cnet article about the refresh rate makes sense... but its also a load of crap. The 600 hz maybe marketing bs, but as the artical states the plasma stil has a clearer picture. Although the 600hz is not real, its simulated

The article is from 2012, so only compares plasma and LCD. OLED doesn't have the same "response time" issue that LCD or LED-LCDs have.
https://www.cnet.com/news/what-is-refresh-rate/

OLEDs actually have really good response times.

LG specs the OLED Response Time at 0.1ms, which is more than a factor of 10 faster than LCDs.

Re: Need advice on buying used Plasma

I picked up the tv... its awesome. Still adjusting the colors

The guy also gave me a Polk audio soundbar 50 and it didnt come with any way to mount it to the wall. How do i mount this thing? I also was thinking i dont want to use the rear speakers on it.. should i leave them disconnected? Or can i splice them in? Then does anyone if the main and the rear are the same? Can i use tge rear as the main and leave the main disconnected as they are further on the ends of tge bar...
