Hope this helps someone!! I've just got a Sony KDL-40V2000 up and running again!! This set came in with the following symptom - blank screen/no picture. Investigations showed that the backlights were operational and all voltages on the power board were correct. The set was brought back to life by acquiring a new T-con board. This is the small board fitted at the top of the chassis under a metal frame. There are three connectors on this - one at the bottom (data) and two flexible ribbon cable connectors at the top which go to the LCD panel. Replacement board cost around £20. Board No. is 400WSC4LV0.4
