Re: CyberPower 1350AVR - Repair
Well, I have damaged my circuit board, as I knew I would. I should hang up my iron before I hurt any more boards.
I had to turn up my soldering iron to 450 instead of 350 in order to desolder the parts off the board because the solder did not want to melt. The solder wick did not want to suck up the solder either. Somehow I managed to break free a pad from the board for the Viper22. It didn't come off all the way and I managed to put it back but I knew it wouldn't work.
After putting everything back together, I plugged it in and it started working. I could run a fan off the battery backup after unplugging it from AC power and letting it run on battery. However, the LCD reading on the screen showed the battery was not fully charged, so I left it plugged in to AC letting it charge. 2 nights went by and now the unit won't power the fan any more, even with it plugged into AC power. The voltage doesn't read 120 but 100 when first turned on and then begins to drop.
Is the board junk? If not, is there anything I can test with a multimeter to see what is going on? Possibly the fuses? Bad soldering by this old fool? Any help from you experts would be greatly appreciated, thanks.
