It sounds that the main board to your TV has the fault. Actually, troubleshooting to this board is a skilled one, and not a user repairable one. It will be best to contact the authorized service center for Sony. If you wish to get some details, check the site linked here. http://electronicshelponline.blogspot.com/ Pull up older posts.

I have a sony bravia kdl 40v 5100 for less than two years and i did not purchased an extended warranty and now my tv is down.
I have no picture, no sound just a black screen when i turn the power on, the power (green) light is lite up and the tv turns off by itself for like less than 30 seconds. I have tried to press as many buttons on the remote control and on the side of the TV to get any message but nothing seem to happen. Any suggestions and solutions? Thanks
Could be the power board or main board defective, but I suggest you do firmware update first. Go to http://esupport.sony.com/US/perl/swu-list.pl?mdl=KDL42V4100&LOC=3#div_pos_30 download the software.
