To replace the TV-UCXP683T-V's fuse
The TV-UCXP683T-V has one fuse.
If the TV-UCXP683T-V'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-UCXP683T-V
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.
