samsung PN60E7000FFXZA jumpy picture

[nwcs]

Originally there was no picture on all inputs. Found lots of bad solder on the power supply. Noticed that the X-main was buzzing really loud prior to re-flowing solder. It is still noisy but considerably less now. The picture is jerky when on any input but not on a test pattern or the on screen menu. When the picture jerks some times I loose all video except the on screen menu. I am leaning towards a bad main board and was hoping for anyone's input. I did not find any bad solder on the main board and the system firmware is up to date.

Bad main board. Also on a side note the Xmain be louder sometimes then others due to flexing the TV back-and-forth with the back off.

You can always try heating up various parts of the main board to see if the issue straightens out while are watching the screen. It's likely cause is a flaky eeprom, bad BGA underneath the main processor or ram I c's located around the processor

I was thinking about using my heat gun and heat them up to see if it fixes it.
