yes it could be a t-con board but could also be a 12V power supply output failure. The Video processing board, and LCD panel uses 12V

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. The fault is related with the video processing section circuit at the main digital board. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

That isn't a timing control board issue, see if you have PSON voltage for starters, if you do then test the various power supply voltages, it could be either the main or power board giving issues, but I would bet on the power supply is bad since the logo comes stays on

About 99% of the boards from shipjimmy are good, unfortunately lI think you have a bad panel and its destroying the tcon board, did you check the fuse on the tcon board?
