JVC LT-55C870(B) and LT-43C888: Status LED Flashing, Netflix Error tvq-pb-101(8.1), No HD Channels

Hi,

I have a JVC LT-55C870(B) where the Status LED flashes at 1Hz, but the backlight is off and there is no display.

I fitted a 17MB130E from a JVC LT-43C888, which does work, gives picture sound and internet, but Netflix does not work and gives error tvq-pb-101(8.1), which is something to do with data on the streaming device. Also anything that requires HD picture does not work. There are no HD digital terrestrial channels either.

Both the 55 and the 43 TVs are 4K.

I think I need to flash the firmware on the original mainboard - can anyone assist with a download link for this TV please?

Or is it possible there is a fault on the original MB? Re-flow the CPU?

Thanks in advance

Hi Russ,

Any luck with LT43C888 firmware please?

I have run into an issue when trying to reset my TV. Unfortunately the reset did not happen and now would not work.

The TV starts, showcases the JVC logo and then restarts itself after some red led blinking.

The red led blinks continuously throughout the process.

Any suggestions on how to restore my TV please?
