The finger below is pointing to the HDMI ports.
If your TV doesn't have these ports then you don't have the ports available.

It sounds to be a firmware trouble. Will be best to contact the authorized service center for Sony, rather than trying to do it by yourself, as it is a very skilled work, need both concentration and previous experience. google.com/+GopakumarGopalan

Either buy a new board or take a HDMI port off of something non working and see if it lines up with the solder points.

Yes ,you should replace the main board ,because you can'nt repair HDMI interface.

Your Bravia should have a 15 pin PC input, this input can take most standard PC resolutions, however if you a have a video card with an HDMI port, you should set your resolution to 1920 x 1080 @ 60Hz refresh rate so that the signal can be recognized and processed, many standard PC video resolutions are not compatible with the HDMI inputs. You should not require audio cables unless you are using a DVI to HDMI connection.

I have a Sony Bravia model KDL-46s5100 that had the same problem. All HDMI ports stopped working. I don't know why this works but unplug the TV for about 30 sec, then plug it back in and hold down the power button on the tv for 10 seconds. Like I said I don't know why this works but it worked for me. Good luck.

Two options are available to you-

1. Through VGA Cable(Same cable which goes from CPU to PC Monitor)- For Video.
Take to PC Mode from MENU -> EXTERNAL I/P -> PC.

2. Through HDMI Cable.
Take to HDMI Mode from MENU -> EXTERNAL I/P -> HDMI.


If Still No Video
CASE1- 'NO Signal' Message Comes, then toggle the laptop screen with Function Key (depending upon laptop company).
CASE-2- 'Un-Supported Signal' Message comes then adjust the resolution to 1024*768 or 800*600 or as mentioned in Manual.

Please intimate me if any other problem comes after that.
