First let me say I can not get the picture to stay on long enough to take all of the pictures I want but in the one picture you can see a horizontal line in the top of the picture. It will run for about 20 seconds then the whole picture will turn purple and get large horizontal lines in video and reboot. It gets faster at this the longer it is left on. I know it is a panel issue, I am just interested if anyone has had any success repairing the problem. twisting the screen or any pressing on bottom tabs makes no difference.

Re: Samsung UN65KU6500FXZA horizontal line in top of picture
I thought I would add the voltages I get when the panel lights up at CNL801
1 thru 4, 18 thru 20 and 27 are gnd
7, 9 and 11 vamp 13v
13, 15, & 17 13v reads 13v
21, 23, 25 & 29 pwm 1.3v
8 od_LEV 3.34v
10 Fail_ct 3.34
12 OD_o/f 3.3v
14 blu_o/f 4.1v
16 Power_o/f 3.34v
22, 24, 26 & 28 PWM 2.25
30. ana_dim 2.5v
I hope this helps some. The voltages do drop to 0 or almost 0 when the tv restarts.
