49UJ6500 LCD panel has a lighter band on top when first powered on. Goes away (or gets much fainter) after TV on for a few min. After powered off for awhile and power back on, same band appears. If powered on immediately after powering off, no or much fainter band. Running the latest firmware.
Disassembled the TV and lifted the LCD panel during testing. Band is on the LCD panel (can see the band on the panel as I lift it slightly) Backlight is perfectly even at the top edge. Double checked LCD panel alignment in the frame and is perfect but since band moved with the panel, its on the panel. Reseated both ends of the 2 T-Con flex, no change.
Have seen similar on 2009-2011 Apple 27" LCD panels made by LG. Those will exhibit lighter band on left edge if not used for awhile. Goes away after awhile and don't come back as long as the i27" Mac/Thunderbolt display (these devices use this particular LG panel) is plugged in
Anyone know what this is? on the Apple 27" LG LCDs, panel seems to want some current flow to get rid of this problem. Appears similar on this TV panel.
