TCON compatibality BN41-00877A 943NW with 2043NWX board BN91-01890T

[rmg_hrr]

Hello all,
Would like to know if the TCON board BN41-00877A 943NW is compatible with BN91-01890T.
If so I will replace my existing BN91-01890T board with BN41-00877A.
My monitor is Samsung 2043NWX.

BN41-00877A




BN91-01890T


My Monitor has below problem

That is not T-CON board, that is the main/logic board which output must match the Integrated T-CON board on the LCD panel assembly. The other outputs also has to match the pinout that go to the power supply/inverter board.
The PCBA on the back of the LCD panel is the integrated T-CON board into the LCD panel assembly.

Ok, thanks for letting me know that this is main/logic board and not TCON.

Looking at these two boards I see no difference in component. Probably firmware may be different.

I have at present the BN91-01890T board other board I have to order and get.


Has any one used these two interchangeably? what is the cause for the problem in my monitor is that due to Logic board or TCON ( long panel back of LCD)?

why not swap that logic board outright, chances are it should work as long as you have the right size of the screen panel from which you took the logic board. as far as I know, it is programmed to fit the size, so if it's wide then the screen where did you took the logic board should be wide too..

just check the pinouts on the left connector has the same pin output too..

my guess the cause was the logic chip on that board that failed to process the analog signal properly.

@EK2oo2
Do you realise how old that thread is?

I do realized. I got the same logic board as the threadstarter and the display seems to be dead (because it has no standby led at the front) but the voltages inside is stable and complete. The problem lies within the main logic controller chip that was unable to execute the program coming from the eeprom chip.

I just answered his open question regardless of how old he posted this.

My apology if I broke a rule.
