samsung le32a456c2d flickering/blinking issue

[mattoxx]

Hi. My samsung le32a456c2d has the flickering/blinking issue. You can see it on video I uploaded.
Power board is BN44-00214A

I found that similar problem was solved by cutting the jumpers. Can I use same procedure here? What jumper to cut? What seems to be an issue?

My video showing problem

Thanks

Hi guys, I just found out that flickering is related to backlight. If backlight is set low then everything is fine. The frequency(speed) of flickering goes up as I increase it.

I did some measurement on power supply on backlight set on both low and high.

low backlight: 24V = 20.7v
12v = 10.5v
high backlight: 24V = jumping between 19.5 - 20.7v
12v = jumping between 9.5 - 10.5v
