To replace the TV-VVTBP-E2's fuse
The TV-VVTBP-E2 has one fuse. If the TV-VVTBP-E2's power LED is not lit, this could be due to a blown power
fuse.
If you suspect a fuse is blown, remove the fuse as described below, and use a multimeter to check it. If the fuse is
blown, try to determine why it blew before you replace it. Check the power wiring polarity of the TV-VVTBP-E2 and
any other devices that share the power supply. Use the same polarity for all of them.
You can purchase the 3 A, fast-acting, 5mm x 20mm glass fuse from Littelfuse, mfr part #0235003.HXP.
To replace the fuse:
1
Remove the cover to remove the red power connector.
2
Press a small flathead screwdriver into the fuse slot, press inward, and turn the screw ¼ turn counter-
clockwise. This springs the fuse holder slightly away from the controller.
3
Remove the fuse holder.
4
Remove the blown fuse from the fuse holder.
5
Insert the new fuse into the fuse holder.
6
Place the fuse holder back into the TV-VVTBP-E2 and turn it ¼ turn clockwise.
7
Replace the power connector and cover.
8
Verify the LEDs on the TV-VVTBP-E2 are lit.
