I have a 30" cinema display that intermittently will start flickering lines like crazy.. Here’s a video demonstrating the problem: http://tinyurl.com/nnc8toj I am wondering if anyone has seen this before, and if it is the power supply? I don’t want to spend $200 on a new 150w HD power supply if that’s not the problem…… Thanks.
I have same problem its not the monitor cable, ive checked this as I have dual monitors and psu’s, swapped monitors same flicker on the one powersupply A1097 90w Update (04/08/2020) Yes just got a replacement powersupply supply on ebay and works correctly.
Have you checked on a different display? If you see the same flickering on a different display it traces back to your video cables or the CPU/VGC. I’d try that test first. If this answer is acceptable please remember to return and mark it.
