Hello everyone,I finished building my LXR yesterday. I did all the tests, although my multimeter doesn't have a continuity test function, I check for voltage when the power supply is not connected and it didn't show a short, I guess, I also did a resistance test and it shows 1.59 k. The voltage test at steps 5 and 16 were good. (4.99v)The unit is powered by a 9v 600ma power supply. So, I powered the unit before installing the OLED and pretty much all the led lighted up, than the green voice led lighted up and I could press the start button and see the chasing lights.It's when I soldered the OLED that things started going wrong. After I soldered the OLED, I started the LXR and a bunch of weird characters showed up, I could still see sometimes parts of words, like «wav».I was able to see the chasing lights. I than decided to check the connection on the oled and resolder it by heating the pads a little. Now everything is black, no led lighting, nothing. I copied the latest firmware on my sd card (Kingston 4gb) and try booting up with the encoder pushed. Nothing.It's worth noting that I'm not super advanced in electronics. ;)I checked the orientation of all the resistors networks, the ICs. Everything seems fine. So... Is my OLED fried ? What can I do ?
