What voltage is a 3-LED light from a LED-TV?
The 94V marking you see on the PCB is not a supply voltage rating.
94V-0 is a UL marking indicating the flammability rating of the PCB material.
As others have said, you ideally need a constant-current LED driver or failing that a series resistor in order to drive that LED board safely.
If you know that they are white LEDs then expect each one to drop in the region of 3.3V.
