Yeah....I read the documentation he published and it's getting waaayyy above my head.
Today (and I didn't break anything...thank goodness) I attempted to separate the LCD display from the control board. That didn't happen. After some attempts with fingers, and screwdrivers (very light attempts) I determined there was more here than meets the eye.
So, upon reading further (and really....who reads it all up front?
) I discovered that Ian soldered each of the 34 connector pins.
So...this pic is one that Ian provided:
And these pics are the front and back views of my LCD and Control Board attached together:
So...it's difficult to tell from the web site where I purchased the new LED screen
https://www.aliexpress.us/item/22557...andl_shipto=US if the "pins" are pre-soldered on the LCD screen, or pre-soldered onto the Control Board.
I'm thinking...hoping...they are pre-solderd on the Control Board. I have a few old laptops in my garage junk pile that I can pull out the board and practice "un-soldering".
If I can't "un-solder" and maintain visual board integrity....then I may not attempt to do this. I'm rolling the dice that the LCD screen is the culprit and not the Control Board.
However, If I unsolder this and destroy the Control Board....I'm still not outta luck as the BMS settings are set...and they are good settings.
But...if I destroy the Control Board then I'm out of having the convince of seeing individual cell balances at a glance. I'd have to do the MM check each cell every now 'n then. I have another digital volt meter connected, so I will know when I approach the magic 50V don't go farther number.
My preference would be to just buy a new monitor.....but sometimes we don't get what we want.
