Panasonic TC-P50U2 Green Band on Left Side of Screen - Fixable?
I've had a problem with my old Panasonic TC-P50U2 plasma screen. For the last couple of years, I could get an intermittent green band on the left side of the screen of varying levels of intensity. It would come and go (sometimes for months at a time). This is obviously an old TV (purchased in 2010/2011 if I remember right) so I have no expectations that a defect at this age isn't very possible, but I am wondering if this is something a) that can be fixed, and b) if it can, whether it's even worth bothering. I do like the colours offered by plasma screens. but it is certainly obsolete given 4K technology (or so I understand). For the amount it is used, we don't really have cause to spend a pile of money on a new one if what we have can be easily fixed and we can get a few more years out of it. Other than the colour band, I do notice that there is a good bit of noise coming from the back of the TV (it sounds like a noisy electrical transformer, but I have no real expertise or reference to compare it against). Would welcome any advice or suggestions the group may have!
A couple of (marginally useful) pictures are attached to give you a sense of the visual. These were taken back in January the last time this problem cropped up, which then subsequently disappeared again.
