HP Prime spares

[Bipman]

Hi

I have been given a defunct HP Prime and wondered if spares were available. I know it's one of the boards inside so just need to replace it. Might be overly expensive though.

It'll probably cost as much as a new one. These things aren't made to be repaired.

P.S. You say it's defunct. Was it ever funct?

Unless I can pick up a broken one for free or small money!

I have a hardware rev. C with low-contrast keyboard you could have (free) but, unfortunately it's not broken. You only want a broken one, right?

Yeah, broken is best. Thanks for the offer but a free working one might be better used by someone less fortunate. Not that I'm Mr. Richy Rich or anything!

Do you know what is wrong with the one you have?

[Bipman]

Yes, the main board inside with the arm chip on is fried. Looks like someone either plugged the wrong cable in and then tried to repair it or the wrong voltage killed some components. I presume this would be the most expensive part to get hence my looking for a broken one. Of course a broken one might also have this board broken so it would be a gamble unless I swap the display for another part etc. but this seems remote.

I would start following the VCC line from the power controller/USB with a multitester. Maybe there is a component that burned earlier than "the most expensive part"

[Bipman]

Unfortunately it is quite visible on the main board with components obviously burnt or at least bubbling under heat and when I tested for power, it was going nowhere.
