content: Hi all,After failing to modify my Advantest TR6143 SMU for European mainsI gave in and bought a mains converter.Unfortunately, the unit does not boot. Seemingly the entire display lights up. The "monitor" lights turn off after about 5 seconds but nothing else happens even after minutes. Not even an error code. Unplugging all but the power cables from the front panel results in the exact same behavior.There seem to be two EPROMs in the unit, one on the DAC board and one on the front panel board. Given the unit's behavior, I'm suspecting a fault in the latter.I tried searching for a set of ROMs online, but no luck. Does anyone here have them? The markings on the sticker on the front panel ROM seem to be1899L-31897L-3.In any case, I tried pulling the data off the front panel EPROM and attached it here. I'm not sure what to make of it, I'm just surprised that a good part of it seems to be empty.After reading the EPROM and plugging it back in, the unit behaves the same.Of course I'd be happy to post the contents of the DAC board EPROM as well. However, I'd prefer to verify that it's functional before doing so.Thanks in advance!

content: Quote from: 42Khz on April 16, 2025, 04:01:15 pmThe first file was the binary version. That's the version that we prefer. A checksum of 0x00 means that the EPROM is most probably error-free.
