Samsung S6 G920A - Water Damaged - Can not connect to computer - GSM-Forum

cqljohn · 06-23-2015, 02:45

I have a Samsung S6 that had water damage, not bad. Board cleaned with ultrasonic cleaner. Bad LCD because of water damage (eat holes LCD ribbon) so can't test very much. After cleaning, soft keys worked, but then gone. Phone can not connect to computer. New Charging flex, same issue. Where to go from here? The phone is charging correctly. Does not seem to power on any longer, but again I can't tell for sure, but no soft key lights. Don't want to buy an LCD if I don't suspect phone will power back on. Have multi-meter and very good soldering skills, no parts seem to be overheating on the board, and no schematic for this phone so I don't know where to start. Please help.

Almost the same symptoms with an S6 water damaged, few little spots on the PCB, perfectly cleaned, but can't power ON. I make this jumper and it is fine now, maybe this can help you:

I'll be damned.....I made same jumper and have power back to board, was able to get in D/L mode and restore S/W with Odin. Since I have not replaced LCD yet, curious if everything else worked well on the phone after this jumper? Also, how did you ever think to jump power here? I like to learn why I did something, lol. Thank You very much!

On my phone everything works absolutely well after the jumper, tested. How i manage to made it : first i connect the phone to regulated power supply and check that if i press POWER ON there is no reaction - no current flow. When i put charger always show me charging at 98%, even if battery is disconnected. So i look for some fuse, didnt find, look for schematic, didnt find, check the power ways - the ticker ones, and found this two points as "suspected", check on another board show me zero Ohm between them, on mine was infinity, the rest is history... Wish you good luck!

Very good, I thought you may have had another board. Mine is up and running, has a gyro problem. No dang schematics to be found anywhere!
