Right 40% of QLED TV Screen Has Darkened

[cyberbiker]

This past week I noticed the right 40% of my 2021 QN32Q60A QLED 4K HDR TV screen darkened. -see image - I bought it about 20 months ago so it was out of warranty. A quick search of the net indicated others have also had this problem. Some suggested 1) pulling off the back and check connectors, 2) dragging a grounding wire around any accessible modules or 3) unplugging the power cord from the TV for a while.

I took these three steps, which seems to have cleared up the problem for the time being.

• Unplugged the power cord and HDMI connections from the TV for an hour.
• Changed the Picture Mode to Standard from Dynamic at Settings>Picture>Picture Mode> StandardD
• Returned the Picture Settings to Factory default at Settings>Picture>Expert Settings>Reset Picture.

If others have suggestions, please add them. If the problem reappears, I’ll update this thread.

That brief article may be on to something. When I went to the Samsung TV settings and reset them to factory default, it seemed clear the black screen up. The TV is connected to the broadband modem by Wi-Fi. The only device I have connected to it by HDMI as an Apple TV. That tends to have higher quality color settings and perhaps placed a load on the TV picture modules. Since I connected the Apple TV back I have had perhaps one instance a dap when the screen starts  to darken but it clears itself up.

I’ll continue to troubleshoot to refine solutions. I’m a little irritated that the Samsung tech-support people didn’t suggest restoring the picture to factory defaults. As it was, I ordered a new TV for $640 before discovering that solution.

That paragraph probably has validity. I only had an Apple TV connected by HDMI, as the TV is connected to my broadband modem by Wi-Fi. I noticed when I went to the Samsung TV picture settings and reset the factory default it cleared the problem up, but I had also disconnected the Apple TV.

The problem still occurs briefly one time a day, with the Apple TV connected, but seems to clear itself up. I will continue to try to refine a solution.

I wish the Samsung tech support agent had recommended resetting the picture. he did suggest we do an HDMI test and that I disconnect the external devices, neither of which cleared up the black screen.  As it was I purchased a new ZQLED TV for $640 before discovering that that Resetting the picture to defaults would clear the problem up.
