[Xperia Z4/Z3+ Q&A, Help & Troubleshooting] futiless:
So my latest of stupid fails entailed the attempt repair of my water damaged E6533 (this was because I decided to take it into a sensory deprivation tank. Which included pounds of epsom salts ouch). I actually took amazing care of this phone and it was in perfect condition and I was excited to use these forums to flash to my hearts content. ANYWAYS I tried drying the board as this happened in August and I left it powered off for approx 1 week in the sun, with more salts. At this point I was nearly sick to my stomach because of my stupid move for one of my most prized possessions. But somehow I kept going, I attempted to boot the phone again but alas no go, I had really fudged this this as salt is more conductive regardless of IP68 this is extreme salt I am such a dumb@$$ I didn't want to admit it until now. But in hinds site it worked for the 2 hours I was in the salt water. Then for 10 minutes after. I then noticed it triggering touches all over the screen. Disregarding my own advice to everyone else I know I did the stupid thing at this point. I tried to turn it on even though it just shut itself off. It did and shut off again during bootup. I gulped as this birthday gift from a friend was turning out to be a "worst case scenario" type of ordeal. Next I kept going like a troubled child again and again I tried. Because in my mind I couldn't imagine how anything could have migrated into the phone. But it was to late ........

BECAUSE if anyone knows how these XPERIA repairs tend to pan out during display damage, you get the picture. Sorry to be so cryptic but for those of you who havn't had the misfortune or need to repair a broken display (*I assume the most broken physical feature of this phone but also any electronic device for that matter.) you may not be aware that the phone has fuse on the mainboard which during display malfunction clearly blows. Replacement of this fuse requires 1) a schematic 2) advanced soldiering knowledge and techneque 3) time 4) bravery ... so on . As it is quite small and actually requires prescission soldiering equipment (here's my fail, failure to use and therefore aquire the proper tool for the job). Yes my dumba$$ory didn't stop at epsom pools of waterdamage but a soldiering technique regardless how good shouldn't have been attempted here. Although I did manage to bridge the fuse to see that YES INDEED the screen came back when bridged and it continued booting. Something prevented me from getting my soldier bridge to actually stay attached so eventually I broke an adjasent resistor. WELL good luck fixing that !!?

But for me I have seen this before. With my Z2 last year. I loved that phone but despite the love Mei case it smashed on the pavement. Screen replacement resulted in fuse replacement. WHICH in turn resulted in a SUCCESS followed by failure short after.

Another friends Xperia Z, same thing : LCD - > FUSE -> in this case I tried AliBaba'ing the board. Which was the ONLY place I could source one '.' With the new board the GPU seemed to have damaged video memory as the screen was getting serious interferance and shaking everywhere. Putting the original board in the same position resulted in no backlight but no shaky image. DOA part ...

SO ALAS

I HAVE a graveyard of Z , Z2 , Z3+ dual and extra parts ... Each time I try Xperia I get hella burned trying my luck fixing a phone I would love to be loving right now. If only I could only figure out a way to fix the lot I would in a heart beat. But most places online seem to be more pricy than the original or unreasonable. <shrug.> :crying::silly::confused::confused:
