Pulsar i3 pro b .. LCD blank .. firmware issue

[Nickallen69]

Hello please can anyone help me out .. ive had an issue with the Y axis not returing to stop switch so all i wanted to do was reverse the direction in the firmware .. once i updated the firmware (and it worked fine) then i changed the direction within configuration.. and verified and uploaded it to my printer .. its said complete but my LCD screen has gone blank with two rows .. its done this once before but it sorted itself out when i uploaded the firmware again .. this time its not having any of it for some reason .. im truely stuck.. its not a wireing issue .. its something to do with the firmware and when i upload it .. any info would be great thanks nick allen.

Have you check the firmware is correct or not and then re-upload it again

hello yes ive been on this forum and re downloaded the firmware and still no luck .. there's only one option of download so im going to have another look and see if there's any other firmware to try .. cheers nick.
