I am trying to repair a galaxy dx2517 with the newer mosfet board. I originally start troubleshooting it because it was outputting almost no power and could not properly adjust bias voltage or current either way I tried. and at some point along the way, it started to switch into tx on its own even in rx after being powered on for about 20 seconds. I'd let it cool off and turn it back on and it did this consistantly after being on for 20 seconds. And now when you power on the radio it immediately tries to switch into rx and tx at the same time and the rx/tx led on the front looks like the red and green light are on together. I've been going through checking parts in the rf driver and final sections, the regulator section near the q37 regulator, and in the tx,rx switching circuit around the q30 through q33 switching transistors and have not found a problem yet. after checking most of the components in these areas I have yet to find a shorted part or problem. I've started replacing a few electrolytics, regulator transistors, a few diodes. I've reflowed some of the areas of solder and have not seen a cold solder joint. I have been careful in soldering and using another galaxy board to compare and haven't found any bridged connections. No dark burnt components. I do have a temperature gun to check for hot areas, I'm hoping someone more knowledgeable can offer some advice and point me in the right direction of where/how to trace the problem. I do not want to give up on this radio since I am learning how to troubleshoot as a hobby. I have minimal experience under my belt and hoping to fix this one to learn something from it. I am new to this forum and hoping I'm in the right place for some coaching. I'm hoping to fix the tx switching problem so I can go back to troubleshooting the bias voltage issue. I can check voltages or anything else at someone's request. The driver and finals are removed while I've been troubleshooting, hopefully that's not a problem. thanks in advance!
