Probable failed main power supply. This may be a separate board that is (carefully) user replaceable. Pull the plug for at least hours, if not overnight, before opening. There can be stored charge in some components that is at minimum unpleasant, possibly lethal.

Dynex 32" tv picture goes black


If there is still about ? 24. Volts coming from the Power Board when it goes dark, it will be the Inverter board that needs replacing. If not, it is the Power Board that needs replacing. The Voltages should be written next to the sockets & plugs on the Power Board.

Dynex tv no picture screen comes on and then goes black


There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc. Look for 5vdc, 12vdc, and 24dvc.

No picture but I have sound


Try a hard restart, which simply means unplugging the power cord of the TV, and replugging it after 4 hours have passed. This technique reprograms the electronics, to a certain extent. If the picture does not return, then your TV has a more serious problem, that requires the attention of a repairman.

Power button is green - no blinks / no picture / no sound


Unplug it from the wall, wait 2 minutes and plug it back in. if problem still exists, its probably the main pcb.
