OK, power light on TV flashes twice pauses then flashes five more times quickly is an error code that indicates Panel 12V supply failure, it means t-con board isn't getting 12V supply or t-con board isn't working, possible causes are either power supply board isn't sending out 12V to t-con board OR LVDS cable between t-con board and main board is misaligned or has got bad contacts OR t-con board itself has been failed and causing the problem.

You would need to remove back cover of TV to access inside. Reconnect LVDS flat ribbon cable between t-con and main board. If problem persist then check 12V at t-con board with multimeter, if volts appear even for a second then replace t-con board. Please check with following board supplier to get replacement t-con board if you have plan to do-it-yourself..

I just lost my job, and spent all my extra money for you to tell me nothing. I'm very disappointed.
Expert:  Shahid replied 4 months ago.

I'm sorry about it, I diagnosed the problem and gave you all the info to proceed. I'm unable to put my hands on your TV from here to check and replace any board/ part through internet.

I hope you'll understand my limitations.

Thanks.
