"Sorry but whats a bad panel? If its a bad panel is the tv pretty much scrap?"
If you have both cables disconnected, do you still hear clicking sound?

Tried it today.
If i have both cables disconnected(LVDS cable installed) there is still a clicking noise coming from the t-con. Held it up to my ear and its definetly coming from the tcon

What can "click" in the tcon board?
Replace Tcon im assuming?

There may be shorted circuits on the T-CON so the switching power supply on the T-CON is turning on and off.
I see five switching PS on the board.

Inductors LD1, 2, 3, 6, and 7 are the inductors for the switching power supplies.

Is there anywhere i can find the schematics for this tv?

Re: Sony Bravia KDL-55EX713 - No picture

In the service manuals I seen so far for Bravia TVs, the schematics are not included and the reason for that according to Sony is that part level repair of the boards are too complicated. So it very unlikely that you will find schematics for your TV

I have the same tv like this kdl55ex713, it have band of vertical lines, intermitant picture bad.
When I put menu, the lines is missing, picture ok, so I am sure problem is T-CON, not the panel.
If the menu is clear, that mean panel is ok.
