STM CircleOS forum / Another Dead Primer2

binraker · 2009-09-16 22:59:47

After a few hours of playing with my shiny new Primer2 the screen froze so I removed the battery jumper and replaced it. On pressing the the joystick to turn it on the screen came on white and nothing else happened. I have re-flashed it with the factory firmware which did not fix it. from what I have read on the forum this could be a dead reg but the fact that the unit only lasted a few hours before dying makes me wonder. If it is a dead reg, where can one get new l6928 regs from?

Hi Peter,

It seems that you got the problem of U9 dead reg. We will contact you by email in order to explain how we will proceed to repair it.
Regards.

FYI, we repaired several Primer2s that had either U9 or U17 dead. When we repair them, we replace the deaad regulators, but we also replace the U23/U56 capacitors (input voltage for the regulators) by multi layer ceramic capacitors (instead of tantalum). It seems that it solves the problem.

I have also had this occur. The battery has power & circle_mgr can connect (usually -- sometimes it reports a low voltage error), but the screen does not show anything & the welcome audio does not play. Please email me the repair information also.

Hello,

My Primer2 is also dead, after 2 days , measuring voltage between gnd and 2v8 pin on expansion connector gives 0.8 - 0.9 V. Same error message from RLink when trying to program unit.

Please contact me by email for repair instructions.

Best regards,
Magnus Lundin

What package size are C23 and C56?

We used at Raisonance 1210 (22µF 10V). Farnell reference: 9527770.
But our subcontractor uses smaller ones.
