Question about Samsung LN-S4051D 40 in. LCD Television
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??
