Its probably a bad ribbon cable on that side of the tv. if u put pressure on that side ( on the plastic) it may resovle the issue. otherwise it could be a bad tcon board and the tcon board would need to be replaced.

More than likely your control board. Available at www.partstore.com Cost could be between $130 and $200. Not that complicated to install if you can use a screwdriver and are careful. Let me know how this works out.
