Help with HP-67 Fault please!
Hi guys, the top row of my HP-67 is unresponsive, completely fails to register in any way. So suspecting a faulty contact I stripped the unit but I cannot trace any dry joints, bad spot welds or track breaks. The horizontal track for the top row leads through to the back of the board just above the A key, and this link is good and the IC leg it leads to is also good. I'm no electronics expert so this is about as much as I can check. The rest of the calc works perfectly...

So before I donate this unit for recycling, does any one have a suggestion on what I could be missing, or is this terminal?

Thanks in advance,

Max
