Ok, thanks for explanation!

I will order new T-con board and then I will see if I get something on a screen!

Hi Diah,

I got new T-con board and I got some strange RBG pattern and I could not see all colors on a screen. Please check picture in attachment.

I tried to connect everything back, but still nothing on a MB and I decide to heat it up with flux and I got picture on TV.
Although, I can see some white/grey colors on a black, looks like pixels refresh issue.

Should I proceed with pixel refresh option from settings? I also do have service LG remote….can something be done with that?

Thanks

the firmware version on the replacement T-CON didst match your version on MB.
as you did flux to repair MB BGA try yours original T-CON who knows could come to life.... if not then you need to replacement T-CON downgrade firmware or upgrade it. to let the 2 parts version matched together.

Ah…..okey that make sense!
can you please let me know where can I find information of the T-con firmware and which firmware is now on installed board?

Thanks

Thanks Diah!

Please see attached picture.
i assume that red “NG” next to Panel matching is not a good sign?!

exactly didn't match..
did you tried yours original T-CON as i suggested??

the factory Data of the panel and t-con marriage saved on the t-con.spi . swipe it or dump both then compare with HEX EDITOR

[Damirget]

I didnt tried with original T-con board, because I install everything back!

I assume that for dumping firmware from T-con board, I would need programmator, or I am wrong?!

can you please share a little bit more details how to do that?

since we are going to take out the SPI from boards to have clean dump / write.... it will be better we swipe them.

Hi Diah,

can you please let me know which chip is a SPI on T-con board?

Are we going to download firmware from chip that I need to take out from the board, or that it is possible with a cable? If it is possible with a cable, do you have a pinout?

Thank you for your time!
