BM235 DC screen (mostly) blank
« on: November 05, 2024, 02:00:36 am »
Fired up my eevblog bm235 the other day and found the dc screen was missing all the numbers. Batteries are ok. (I changed them just because I know you'll ask. No leakage to report.)

[ Attachment Invalid Or Does Not Exist ]

The volts ac screen looks normal. Cycling through the DC ranges I see blank (auto), blank, -55.03, -550.3, 0L. mV dc appears to work normally, but I don't have a mV reference handy to confirm it's accurate. The rotary switch seems fine mechanically. Again, batteries OK. Innards look clean.

Any suggestions how to trouble shoot?

Much thanks,
Jeff
