HI James,</div>

Given the long lead time, why don't you try simply checking the voltage outputs from the linear regulator if that seems fine, try changing the socketed semiconductors chips without getting into the effort of testing each one (it saves time).
Also replace any electrolytic capacitors if this unit is over 5-7 year old. Also look for any obvious sign of component damage or burn out/degradation.</div>

<div dir="ltr">Hi James
<div> What is the cost they are quoting you for the board? If the price is significant, maybe think about buying a system at auction </div>
<div>and cannibalizing it. Today I received an email about a large auction occurring soon and you might get lucky this way.</div>
