First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having.

If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

How to do default settings on sony bravia kdl-46s4100


If there is an answer to this question, you will most likely be able to find it on AVSFORUM dot COM - once there go to the LCD Flat Panel Displays section and then search or scroll through the list of models. The Bravia kdl-46s4100 is approx 6 yrs old, so what you're looking for is going to be somewhat buried and by this time the discussion thread may even be closed, but whatever information is there should be extensive, as this was a popular model when new. Note also that the "46" in the model number refers only to the screen size (46") so information for any KDL-xxS4100 (where xx = the screen size) should be relevant to yours. Hope this helps.
