If your TV is staying on and you hear audio after the picture goes dark, then you have a problem with a CCFL or the inverter circuitry that drives them.

Most likely an inverter problem.

Like a bad xformer (usually fogged up plastic wrapper)

Or a bad cap (bulged, swollen, cracked)

Or maybe a shorted IC or transistor (test for short circuit between the different pins of the device)

Samsung LN-S4051D (great picture bad tv.)
OK, Here it is again:

Changed capacitors, changed main board (TV repair shop tested said it was bad). Wrong!!

Same symtom no picture but have sound. Can shine flash light on screen and see images. From what I gather this sounds like inverter problem. I will send back main board and try inverter unless other feedback??

Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electro-medical.blogspot.com/
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
