I have a pinball machine with damaged connectors on the power board.
The board itself looks okay thankfully (fingers crossed)
I need to replace the connectors but I cannot seem to find the name or part number from the manual.
I am attaching pictures - can anyone give me the name for these type of connectors and where to buy them - also is it as simple as push fitting the leads into them - or do I need a crimping tool?

Thanks in advance
IDC = insulation displacement connector

It IS as simple as pushing the wires in, but you need the correct tool or it will be an exercise in frustration and you likely won’t make as reliable a connection (then the new connector may overheat too, due to excessive resistance).
The Marco page linked above has several of them; the cheaper punch tools work fine, but if you have a lot of connectors to replace it might be worth investing in one of the C-clamp style units as they are a little easier to use and quite a bit quicker.
You shouldn't use the same type of connectors, as you can see, they didn't last. You should use connectors with crimp style pins , instead of "punched". For example , this marco kit uses exactly that , crimp style connections.

Of course if your machine has now LEDs all over , the current draw will be significantly lower , and newer , higher quality connectors won't ever burn again.
Thanks for the feedback
Well I will go for the connectors first as I have LED throughout, I cannot replace those headers without risk of damaghing traces.
The plan is to get several hours of pinball in and get the board overhauled professionally.
At least use a small metal brush or something abrasive to scrub the oxidized pins. Also , pay attention to connectors J101 and J102 (far right of driver board), as this is the input voltage and more often than not , these pins need attention as well (most common issue is random resets).
