Hello all:
Have a nice 2467B and 2465B, both were great until the dreaded TEST 04 FAIL 10/11 etc
Finally got around to pulling A5 board, removing the Dallas NVRAM, placing low profine machined pin socket and copying the image.
Of course both had leaky SMD electrolytics, so some minor PCB rework, replaced a few SMD resistors, etc.
We now have suspicious image data, so probably failed NVRAM battery, as the newly written 1225 NVRAMs give same symptom.
QUESTIONS:
1. Are images and data similar for 2465B and 2467B?
2. On 2465B A5 J4241 has a ribbon cable inserted, but NOT on 2467B.
Why the difference? The connector interferes with the NVRAM on the machined pin socket.
3. Does anybody in the EEV community have default images for the NVRAM?
4. With a very fully equipped lab, but no experience, is there a steep learning curve to do a full cal?
Heard its 4 hrs min and if any of the 200 steps gives out of limit, the entire CAL fails at the end to write.
Many thanks
Jon
