Thin stable coloured vertical lines on Samsung UN65NU6900FXZC come and go

[polaro]

Greetings,

I've bought a used Samsung UN65NU6900FXZC LED TV. It worked fine for some time and then developed, at first, a single very thin (1 pixel) vertical stable blue line, from top to bottom, close to the left edge of the screen. Now it's 3 lines on the left. When I connect HDMI sources the number of the thin lines grow. After disconnecting and cold discharging I am back to 2 lines. The lines disappear at a rate of 15-20 minutes per line. So it does not look like a damaged LED panel. Any advice? Thanks

Failing panel. Google Sony tcon training manual. Your model has an integrated tcon and no separate tcon board.
