Then;

1-Pulled off battery

2 -Cleaned flex cables with alcohol.

3-Putted everyhing back.

4-Putted battery back.

5-Tryed to power on.

Now:

When i try to power on vibrates 1 time as normal and 5-6 seconds later red led blinks 4 (not three) times. No thing happens. If i try to shut down by sim slot button its acts normaly and vibrates 3 time.

Anyone knows what is the meaning of 4 time led blink.

I have very strange problem and I want to know if anyone else has experienced this before :)

So I got this sony xperia z5 compact that I am trying to fit new LCD on, I have tried 4 different LCDs and all of them are not fitting in. It seems like the LCD is not in the correct position so it doesn't fit into the frame.

My question is anybody had that problem before and if yes is there anyway of fitting it in?

Thank you in advance :)

I just changed the screen of an Sony Xperia Z5 Compact.

I bought the screen on ebay.

When the screen was changed, the phone startet up an vibrates as it should, but the screen is black. It's not totaly black, because it sends out a super dim light, so it gets a bit brighter, but still its about just black.

I tried to use another moatherboard i bought some time ago, but that did not work either.

So I think it is the screen. But the new screen does not look damaged, and the cabel dose not look damaged either.

I also think the touch works fine, cause i can manage to click buttons to make the phone vibrate, but i don't see what I am doing.

Has anyone had a similar problem? I bought another screen, but if you know something else it could be, then i'm happy to hear it!:)

Thanks!

After a short visit into a swimming pool a few years ago, my Z5 Compact had difficulties running. I have some data stuck on it since then and I decided to try to retrieve it.

When I power it on, the loading screen appears (Sony then Android) but once it has booted the screen goes off. Sometimes I can see the lock screen for a few seconds, sometimes I don't. The phone vibrates when I put my finger on the fingerprint reader, the same way it would vibrate when you try to unlock it as it would be running fine.

The screen is completely black : neither the dim light nor the screen seem to be working.

I just purchased a MHL cable to be able to plug it to an external screen. There is a signal but it is also completely black.

Does someone have something in mind ? My goal is just to retrieve the data but if I can make it work again I would be really happy !

I guess I will order another rear cover adhesive and go back in and try to wiggle parts around, but I don't know what to look for specifically. Has anyone else had this?

I have no service on my Xperia Z5 for 2 days now. I tried the following:

*#*#4636*#*# and change to GSM only, switch on and off Mobile radio power and restart the phone as I found in a popular tutorial. It does not work.

I tried to uninstall all the new apps I had installed in those 2 days and it does not work either.

My phone is back in WCDMA preferred now but I still have no service.

I restarted it a dozen times without it changing anything.

Can someone advise something?

The original question on XDA

⟐ Edited by author January 30, 2018 at 21:07 MST

• gyroscope not working

• accelerometer not working

• sim reader not working (with the sim inserted it does not get recognised)

• compass not working (tested through G Maps & GPS Test)

Regarding the sim reader, although complicated and risky, it can be replaced, but when it comes to all the other problems I can’t think of any decent solution.

Do you have any idea about where on the motherboard & what type exactly are the chips responsible for the gyro, accelerometer and compass?

P.S. Buying a new motherboard or another phone is not an option. As I cannot benefit from the warranty of the phone due to the strict location conditions enforced by Sony’s Customer Support program I am looking forward towards improving my soldering skills with this (once) wonderful piece of technology :D

Tried all Sony help descriptors ,10 sec power off, 120sec power off, connect to Sony Companion. Nothing helps. Phone is not picked up with the Companion software.

Looked at You Tube no help. Checked battery voltage after charging sitting at 4.09 Volts, This is well above critical min. voltage. Disconnected battery from motherboard, slight more voltage in battery.Reconnected battery, still unable to restart.

powered via USB connector no restart, NO power indicator.

After a short visit into a swimming pool, my Z5 Compact had difficulties running (what a waterproof smartphone ...). I dismantled it, removed the water in it and let it dry. I reassambled it but I still have a problem.

When I power it on, the loading screen appears (Sony then Android) but when it's on the screen goes off. Sometimes I can see the lock screen for a few seconds, sometimes I don't. What annoys me is that the phone vibrates when I put my finger on the fingerprint reader, the same way it would vibrate when you try to unlock it as it it would be running fine.

Does someone have something in mind ?
