Question about Sony BRAVIA KDL-40S2010 40 in. LCD Television
Picture suddenly went black for no reason. No picture at all but have sound. Was working one minute and black 5 minutes later when turning on the set
The reason it is having this issue is usually due to a very small fuse that is blown on the T-Con board. The board could most likely be bought on E-Bay cheaply and replaced if you are not technically inclined. If you know electronics then, Here is a video explaining this issue!

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should troubles shoot. Contact any service technician. The circuit will differ with models and versions.
