imac has a burn mark on the logic board

i have a imac emc2266

i recently came across a imac alumium 20 inch and the guy said it doesnt boot and doesnt chime

i have tried every setting and every test still nothing.T

The fans spin and the computer tries to boot

led 1and 2 are on but the logicboard doesnt have a third led

the computer will run a mouse but the keyboard will not power

i checked the logicboard it has a small burn mark

next to the audioboard

iMac, iMac a1224 QP91175H0TH non function

I doubt any of those have burn marks. something on that board has fried causing the burn mark. you could find the failed part and try to replace it but you never know what else failed at the same time or failed because of the fried part.

I think macs are great computers but i see people spending ungodly amounts of money to get them fixed when sometimes all it takes is replacing the cmos battery inside.If the mac is not working correctly people always reply its the logicboard.Then i hear well its a old computer then i tell them then why are you charging 400 dollars for a old logicboard.
