Problem with HP 25

[krazyk]

Yep you guys were right......

I feel like such a NOOB on these Woodstock calcs.

I upped the voltage by changing one of the AA batteries and up came 0.00 so thankfully another HP25 has survived into the 21st century.

I have just gone out and purchased DeOxit in its industrial strength nail varnish style bottle and will apply 1 drop to each of the VIAs that are under each of the switches on the keyboard PCB.

Heres hoping after some keypressing that 4 and 5 come back to life. 1 an 2 are fairly intermittant as well so it needs it thats for sure.

I read about Pannamatiks Low Voltage Mod and am sorely tempted to just DO IT to this unit.

I am thinking though that you guys would suggest waiting to pick up a VOLTAGE failed ACT unit and do the mod to that. What would you guys do?

Anyway thanks for your help and will let you know if and when I get my buttons all working properly.
