HP 67


I have an HP 67 which did work perfectly until suddenly by switching it on it start showing a display with all zeros in uneven brightness and no reaction to any command.
On and off repeatedly does not do anything to the status of all zeros.

Anybody can help me?

May be there is still some repair shop around.



Fix That Calc says they repair the HP-67.
