First check the power supply board for some bad caps (capacitors) on the board. They will look bulged on the top an may be a little leaky (brownish stain).

If the screen is black and none responsive, it is probably the back light inverter. This illuminates the screen. you will see multiple wire plug into it, usually white/blue or white/pink wires.

Samsung s42ax-yd01 - No picture / Sound OK problem


Hi,
If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
If your TV, flatscreen, or monitor is more than 5 years old it is more like to have suffered a component failure.
Take it to a repair shop.
