TV picture is dark but has sound, did flashlight test and can see a faint picture.


Usually means inverter or power board is bad! Check power board for voltages. Voltages are usually printed on the header port. if Inverter is bad panel would need replacing. If TV is less than or equal to 12 months contact Samsung for warranty repair.

Faint or no picture on olevia / syntax tv model LT-37HVS


When you tune to a station and get sound I presume the screen is black so do the following.
Place a bright flashlight against the screen. Look for an image around the edge of the flashlight.
If you see an image the problem is probably one of three causes.

1) Power to the inverter board is bad.
2) Inverter board has failed.
3) The CCFT(cold cathode fluorescent light) are dead.

Someone knowledgeable in electronics can diagnosis it.
