The ISL88739 & ISL88739AHRZ are a highly versatile combo battery charger
configurable for operating as either a Hybrid Power Boost (HPB)
charger or a Narrow VDC (NVDC) charger, supporting 2-, 3-, or
4-cell batteries. Both configurations allow the battery to work with
the adapter together to supply the system load when it exceeds
the adapter capability, referred to as system Turbo mode. HPB
charger configuration reverse-boosts battery energy to the system
bus to help the adapter provide the system power in Turbo mode.
NVDC charger configuration...-

by justice171Hi everyone,
I'm working on a JVC TV for a client that's stuck on the "Wisdom Share" logo screen.
It's a model LT-50N795 with a board number TP.HV510.PC822. I attempted a firmware update via USB, and while the upgrade was completed successfully, the TV is still stuck on the Wisdom Share screen on reboot.
Has anyone encountered this issue before, or does anyone have any suggestions on possible solutions?
Thanks in advance!
