G'day,
I have an HP 41CV that has developed the nasty habit of automatically turning off prematurely. Instead of waiting 10mins it turns off at any random time between 10 seconds and 10 minutes.
On the assumption that the problem might lie with a leaky capacitor I have swapped the electrolytic capacitors with new ones and even tried tantalum caps but to no avail. Does anyone have a solution for this irritating behaviour?
Also on the PCB there is a device resembling an electrolytic capacitor encapsulated in unlabled grey heatshrink. The device appears to be slightly waisted as might be the case if you applied heatshrink to a bobbin. It is about 10 mm long and about 6 mm Dia excluding the leads. It has two leads exending from one end. Does anyone know what this device is?
Cheers, Ron
