At last--something that's fairly recent and made just before Panasonic decided to screw up their Plasma Production and reputation by cheapening everything to the point of destruction, has come my way.
This 2010 set was dead with 10 blink. A few quick checks showed no shorts of SS or SD boards, and I turned my attention to the PSU.
Checks of the board fuses showed the 5A supplying the Vsus regulator stages was blown.
A few more checks showed that the two 12N50 MOSFETS were short-circuit and further checks of the driver stages showed no other issues.
I had a couple of 13N50 MOSFETS, I had ordered--for summit--that hadn't been used, so fitted those with a new 5A QB fuse.....
The set fired up and worked as normal, and time-of-use indicates only 4,000 hours.--Which was nice after the run of bad COF chips, bad panels and other horrors Ive had lately.
Not long ago, I had repaired a 2011 Panasonic plasma a TX-P42U30, and was not impressed by its build-quality or its picture--TBH, I thought the picture was crap, so didn't hold much hope for this year earlier one!
The difference of picture quality of this 'G20' set is Quite Different! I was impressed by its picture quality, the lack of motion blurring or frame-flicker and the black-level. It doesn't seem to have that annoying floating-black level the later set has. Running blu-ray through it is brilliant while the HD freeview is pretty impressive too.
It has (for a Plasma) a pretty bright image too.
--This one's a keeper--Finally get to retire my 42PZ70!
Only thing that's irritating about this set--While picture is outstanding--The Sound from its internal speakers is Terrible, no matter what you do with the settings, its hollow and top heavy!
The set consumes 200W less power than the old PZ70 but still gets Bloody Hot! --Some extra cooling may be added.....
