There are different screens and they don’t all work with the same LCD board. Though I often see people linking to a specific board as if it works with every cabinet. Kind of frustrating. I suggest you check this if you haven’t already.

On the back of your screen, there should be a sticker with the model number of that screen. For example, the screen with my centipede cabinet is M170ETN01.1.

The LCD controller board you buy should specifically refer to that model number. You can search for “lcd comtroller” followed by the model number.

This is the board I got. Notice it mentions that model number.

I just modded one and this worked for me: https://www.amazon.com/gp/aw/d/B07MRJG3HT?psc=1&ref=ppx_pop_mob_b_asin_title

Don’t buy a LCD board for a 4:3 monitor. You will have part of the image duplicated on the bottom
