MD30112IC21(FSD200), blown 2x pins blown away looks like it arced to a wire rail every thing else looks fineneed to know where i could get the chip from or could there be alot more damage. tested other power outputs and there reading ok

Most likely problem is the display panel. You might check the connectors between the T-con & panel looking for corrosion or signs of arcing. If you see corrosion or arcing signs, clean those areas & see if the picture is now OK. Otherwise you need the Panel & it is not cost effective.
Quite possibly just blew TV fuse, but may have more damage, usually to the power supply circuit.
Unplug TV & remove back & do a visual inspection of all PCBs & wiring. your looking for physical damage, traces of arcing, parts blown apart or damaged/discolored.
Your description roughly fits what is called a 'cold solder joint.'
The crackling you hear may be caused by arcing around a defective solder joint and these can start a fire by igniting the epoxy of a circuit board; it's not wise to count on the arcing to stop by itself although once the joint has expanded slightly it may restore contact for a while.
This type of failure is normally related to a junction carrying a relatively heavy current load, hence the arcing.
I would not use the set until you have made a thorough visual inspection of the boards with particular attention to any separate power supply board. This kind of failure is normally visible under magnification and you may find a crack around a heavier pin.
Look for charred areas around the failed joint and if you find one, it would be safer to replace the board but it is also possible to scrap away the burned area and restore connection with a wire bridge; the charred area can be conductive and still cause a fire.
Check the PSU/ power supply unit not the cord. The cord is never the issue in this complex problem. You may have a blown fuse in the PSU if its a IC intergrated circuit then it needs to be looked at by a qualified Tech.. We only can help you without looking at it, hope this helps
I found a replacement adapter at LCDPAYLESS.COM it will arrive soon I will log-on as soon as I get it to let you know if it works. I never ordered anything from them before hope it works. Also i will keep my receipt and seen it to protron to have them refund my money
