My LCD Controller board : Model No: hdvx9-as v4.2 (https://www.kazmielecom.com/2018/10/12/hdvx9-as-v59-software-free-download.html)

I have set the jumper to 3.3 V (As per panel & Board datasheet)

I have set resolution setting to 1366x768

Laptop Old LCD was working fine in the laptop till i disassembled it. (So i dont think LCD has an issue)

Do you have the LVDS cable? A 6bit-1CH LVDS has different pin population that for instance a 8bit-2CH. Vcc and GND are at different locations and a wrong cable could potentially fry your LCD.

I am on my phone without my glasses, so I can’t see very well but on the imgur picture it looks like a 8bit-2CH cable while a 1366 resolution seems more like 6bit-1CH (just a guess from my little experience with LCD panels, don’t take it as a fact).

Have you tried to hook it back up to the old laptop to see if it’s still working?

Also, have you flashed the right firmware for the controller board?
