you cant force updates, and they may never be another update. updates are only made when there is a problem with the software in the tv

do this test, turn tv on and touch the screen if you can see light in the background it is the panel if no back light is present then it is the power board.

I had a similar problem, checked all of the TV's control settings only to find out that my cable box had an independent "mute" function that automatically turned on the closed captions when activated. Once I found that and turned it off, all was fine.

I had a similar problem. Take the batteries out of the remote, press down on the number 5 for about two minutes the put the batteries back in. This worked for me.
(I got this tip from a telesales advisor. I was close to buying a replacement remote but this tip worked. Hope it does for you. I'm not sure on the science part of it but it basically resets the remote. Good luck)
