Noticed an issue with my KRP-500M and it's freaking me out!
There's an abnormal electricity/static noise from the panel, I'm not talking about the regular plasma buzz as I'm used to that by now owning 2 Kuros. This noise is specially pretty bad when the panel boots up (the phase where the blacks look grey then it dims to normal black levels in 10 seconds or so). Here's a sample I recorded (when turning the Kuro on) because I can't explain how it sounds, make sure to crank the volume a bit to hear it properly because I recorded it with my phone so sound quality is pretty poor:
It's like random electric charges are going through the circuit boards or something, noise comes from throughout the screen but mostly from the upper left and lower right corners of the screen, not located in one specific place for sure. After it boots up, the set behaves normally for the most part but it does make those noises and it's very noticeable when the Kuro is switching signals (like going from 720p to 1080p) or when I put it on a blank input with no signal.
With regular content, I can Still hear a tiny electricity static pop noise every once in a while which might be related to big contrast shifts on the screen, but those happen pretty rarely and are barely noticeable if I enable the sound (was testing without audio while being OCD as hell). It's not normal behavior though and I'm afraid using the set might lead to something getting really messed up if I ignore this issue, I have no clue what's causing this!
2 things that I'm randomly thinking about right now that might have caused the issue:
1- There could be something wrong with my room's electricity, my 5020FD functions normally in the living room, I'm going to check the circuit breakers tomorrow to see if they're running on the same circuit and to calm my OCD I'll probably take the panel to the living room (they're right next to each other) once my brother happens to be at home and test it there, just to confirm 100% nothing in my room is causing an interference or something.
I've already tried plugging it on a different socket using a different power cord as well, but nothing changed. Changing power save modes doesn't eliminate this issue as well. I also tried unplugging the only HDMI cable connected to the TV and it didn't make any difference.
2- Second thing is really random but I'm kinda desperate here lol, my KRP-500M wasn't installed using an official 500M table stand, another pioneer stand was used which fits perfectly fine, but there's a small issue with the screws, I'm assuming the stand bolts were meant to be used for Kuros that are thick like my 5020FD so the upper screws are larger than what my KRP require and a part of it sticks out, here's an image
. It's not possible that after a year + somehow those washers is causing a short or whatever electricity issue, right -_- ?
Couldn't get my hands on the proper bolt length to change those (m8 23mm if I'm not mistaken, probably should look for 'em again), the stand is stable though, but I'd be pissed if this somehow caused the issue I'm having now.
Could this be a power supply going bad symptom btw?
For the time being I fully unplugged the Kuro and cursing my stupidly bad luck now that my 5020 has the red tint issue and I'm facing this weird as hell issue with the 500M, I was looking forward to at least use it for the next 2-3 years until a worthy HDTV is available to upgrade to and was really excited to get a PS4 in March along with MGS:Ground Zeros to enjoy an amazing red-tint free Kuro image, really sucks this happened now.
Any help/ideas would be much appreciated guys.
