My 55" TV has red pixel issue,not fixed with firmware update

by ieditavid / June 22, 2015 10:31 AM PDT

PN50C450B1D model with red pixel issue. I downloaded firmware update and the problem was fixed but changed to a different problem. The first set of red pixels were bright red and seemed relegated to certain images, like peoples faces or hands, not the entire screen. Now, that problem is fixed but there are duller red pixels that cover the entire screen and are not image specific. Help?

There are internal adjustments a tech makes. Be sure to call it in, get an estimate. This was posted widely in AVS Forum so I'll stop here.

I am a consumer who has no idea what those links mean or how they relate to my problem. I'm not sure you were trying to be helpful by pointing me in the directions you did and then "stoping there." Where was it exactly that you stopped? Short of being helpful? I did ALL REQUIRED UPDATES AND FOLLOWED MANY THREADS before I posted my question. Sorry that it annoyed you to a point that you decided to passive aggressively post. Please do not respond. You are almost as unhelpful as calling Samsung directly.

The issue is usually a board or an adjustment.

All sorts of folk land here. I supplied some backup material for those that think it's a setting. Yes, the drive levels are settings inside the TV but not considered user/consumer setable.

I'm sorry you feel I didn't fix it. But you are right, I'm not able to visit everyone to see if it's that drive level. I hope you understand that. As to stopping, some folk demand we duplicate prior discussions in some areas, since this area is known by some I thought it best to keep it short which upset you. I'm sorry about that.

Make the call to Samsung and get an estimate.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
