I had exactly the same problem with a 2yr old LN32A550P3F. I ruled out the power supply as all of the capacitors appeared to be ok. I was able to find an exact replacement for the main board online and decided to replace the board. That took care of the problem and I now have a working TV again.

How do I fix my model tv No picture but knocking sound?


The knocking sound is the high voltage trying to fire. That would tell me that the high voltage splitter has failed or one of the 3 picture tubes (not lamps) has failed. Most likely too expensive to repair a TV that old.

High pithed whistle when tv is on through S/sound


If this is an audio question then let's assume that there are differing grounds between each unit.  There are devices on the Internet that show that they can remove any background sounds between two devices with differing grounds.   http://www.beststuff.com/audiovideo/xitel-s-new-ground-loop-isolator-stops-speaker-hum.html
Could you have plugged in an analogue stereo into a digital output on your tv?
If it is a component inside the tv then this may answer the question.  I found a high pitched ring in a tv i owned once.  It was a fixed coil inside that wasn't factory glued tight enough to not vibrate using it's magnetic field.  it looks like a ferrite rod with magnet wire wrapped around it but just one layer and only about an inch high.  It is probably similar on your tv.

My samsung TV won't show any picture/sound.


When the TV is on, need to check the back light is on(go back side & look into through)

If the back light is on -- need to exchange the Main Board
no back light -- exchange the Power Board --- 95%
exchange the LCD panel --- 5%(inverter)
