Troubleshooting procedure for No-Picture is given in detail.

Hi Tradeboyle,
Please search 'Sony Bravia KDL-40S4100 40 in five blinks' on google and you will get several videos containing the solution of your problem.
Good luck.

Yes. You can. Even though the number of prongs are different, there will be only 2 conductors connects the TV circuit.

Main PCB is bad . I just got the information from a Sony authorize servicer price for the part only $504.87

if it is a black block, look in the menu under closed captions and see if it is in the text mode. if so change back to cc1 or turn off.

Look on EBay under Electronics/TV Parts

Have the same tv with the same problem. Changed the power board - no help. Next I changed the inverter board - no help. Only thing left is the LCD screen. I junked mine out. Hope I helped you out even if it wasn't what you wanted to hear.

You do know that the screen alone will cost you approx. 75% or more of the price of a new TV don't you? Good luck !

This is a screen tab fault and in most cases will require the screen replacing

These things draw a huge surge current when turned on. What size fuse are you blowing? These things can surge 10-12 amps on turn-on. What about a fuse with a reset button. They will take alittle more surge before they go. Don't matter about the insignia working before because the cheaper sets tend to stay powered up more when off....thus not surging on from a dead start. Could you try a different plug on a different circuit/fuse? and see if that makes a difference. If you have a 15 amp fuse, then your pretty close with other stuff plugged in. What size is your service? Do you still have an original 60 amp box with screw in fuses? Is it an old house?
