Re: Weird Plasma Problem, need help Please?
Very common problem with Samsung LCDs is the use of poor quality capacitors in the power supply. Your first step would be to take the back cover off the TV and take pictures. Inspect for any loose/dodgy connections and visibly bad capacitors. (Most likely "WB" or "XC" written on them.)Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

I have an LG Plasma TV 60PM6700 for the past ~12 years.
In the last ~3-4 months I have been having some issues.- Problem: It started with random picture disappearing (sound still worked).
Frequency: Happened about once a week.
Solution: Had to turn off TV wait a few seconds before turning it on again. - Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.

I recently got my hands on a 60" Panasonic P60ZT60 plasma tv (european model) that has some strange issues along with an 8 blink code.
It know this tv is getting old but it was once considered one of the best plasmas ever made, and i think it is still holds on to that even by todays standards.
So, long story short. When i first got the tv it had a very bright washed out picture with very raised blacks in all picture modes and i couldn't find the cause in the picture setting menus.
After doing a factory reset this problem was gone and the picture was back to...01-06-2025, 06:02 AM -
Normally, I never post repairs this quick after I do them, because… I am usually very slow.
But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. 
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

I installed a new keyboard and it can smc reset and the power button works. but nothing apart. no boot picker e.g. I am wondering how this can be explained if the alt key (smc reset) is working. I am aware that on the board side shift, ctrl, alt and pwr are separately wired but the board, trackpad/cable are good. The keyboard was tested working prior installing and as another keyboard now tested on the same board improvised works as well the only idea I have is that I damaged the keyboard flex cable while installing it into the case. But why hell smc reset and power are working then ? Anyone has...
