1 monitored services unavailable

com.apple.thermalmonitord unavailable (or words to that effect)

I assume from that there is a heat/thermal sensor in the phone that i’ve maybe not connected or another part that needs replaced. Any pointers to where that might be and what part I should try replacing?

Thanks!

After replacing lcd I have noticed that about 10% of the screen has a yellow spot on it. All i do is wait couple of days and spots will disappear.

What causes this issue? Is it some clue or what it is.

Thanks for you reply.

However the touch button wasn’t seated properly so I reopened and re-seated.

Now, I remember when reading on the screen replacement manual that came with it “make sure to disconnect battery before working or guaranteed failure” to that effect.

But because I was in a rush this time i dont think i disconnected the battery prior to removing the screen.

Now the phone is completely lifeless.

Im wondering if the phone has a fuse, or what would be the most likely cause of a dead phone after replacing screen without disconnecting battery properly?

Im hugely distraught from this since it was clearly working before i re-opened to fix home button..

Any help appreciated

Phone Information

• Model: iPhone 6 (A1549) 64GB
• Carrier: Verizon
• Operating System: Latest iOS (no jailbreak)
• Age: 2 years

Problem Symptoms

• Press power button, Apple logo appears for a few seconds then screen goes black and the process restarts.
• If left alone, process will repeat for about 10 minutes before the cycle breaks and the screen stays dimly backlit for hours.
• After a few hours the dimly backlit screen will drain the battery and phone will shut off.
• Pressing power button now will show the dead battery screen indicating to plug phone in to recharge.
• Once plugged in, phone will recharge and boot back up to start the whole thing over again.

Problem Origin

• I broke screen a few weeks ago and replaced the LCD/Digitizer with a new one from Amazon.
• New screen seemed to be working perfectly fine for weeks.
• I noticed battery was draining faster after new screen installation and proximity sensor stopped working.
• Suspecting damage to the front camera assembly while switching it to new screen I ordered a new assembly from Amazon.
• Phone was working fine until this point; This is what I did the day my phone died:
• Turned phone off.
• Disconnected battery connecter.
• Disconnected screen.
• Switched out front camera assembly.
• Reversed process and powered up.
• Phone has been stuck in this reboot cycle since then.

Troubleshooting

• First thing I tried was simply going back with old camera assembly. That changed nothing; phone will power on, show log for a few seconds then restart.
• Tried starting with the camera assembly completely disconnected and nothing changed.
• Tried starting with nothing but LCD screen connected (no digitizer, no front assembly, no home button) and nothing changed.
• Disconnected battery and tried starting while plugged in to charger. Phone got stuck in reboot cycle again as if nothing changed with battery out.
• Let battery completely die until phone indicating that it needs to be plugged in to charge. Then I left it on the charger overnight. It recharged, powered back up and loop started again.
• Replaced battery with a new battery and nothing changed. Tried a third battery, nothing changed.
• Took phone apart down to logic board to see if I had accidentally disconnected something and brushed all connectors before I reassembled. No change.
• Updated iTunes then plugged in my phone to see if I can get a firmware update. As the process starts phone reboots and gets stuck in loop again. iTunes says I should do a restore.
• Tried manual firmware update by holding shift while clicking "Update" in iTunes and used the latest firmware file which I had already downloaded. As soon as update process starts phone reboots and gets stuck in loop again.
• Started restore process in iTunes acknowledging that it will wipe all my data. As soon as restore process starts phone reboots and gets stuck in loop again.
• I can put phone in DFU mode and then kick it out of DFU mode using Tenoshare's ReiBoot. I have not tried using ReiBoot pro which claims it can fix this issue but reviews looked shady.
• Swallowed pride and took phone in to a repair shop (not Apple Store). They said they have no new ideas beyond what I tried.

I am completely out of ideas. If you have any suggestions that may save my phone I would love to hear them; will ship beer to anywhere in the US for an idea that works!

This has happened at least twice to me. I actually just finished working on another phone as I type this, and although its now down to “Try again in 40 minuets” I am not expecting it to get all the way to zero and let me enter a passcode, because it hasn’t in the past.

WTF is going on? What am I doing wrong? Or is it me at all? Is there a way to prevent this from happening during a repair? I am getting a lot of upset customers from this.

P.S. I just checked it. Its been at least 3-4 minuets, if not more. Still “Try again in 40 minuets.”

Working for a repair center, we already have the annoyance of iPhone 7 acknowledged failures. This just adds to the headache of the newer models, with the latest update in software. Replacement of service antennas and reflows have been attempted, but with no repaired results. I am wondering if this update has triggered a board level failure.  Perhaps another update will resolve the issue, but anything anyone has discovered to correct the problem, as is, at this time would be helpful.

Recently i've had to replace the lcd screen of the iPhone 5s.

Everything was working allright.. (the old screen was still working, just messed up colors) but now when i plug it in it displays black screen.

I have also tried plugging in the brand new screen and same issue.

Now i'm not sure whether it's screen issue. So i have few questions

1. How do i know if the iphone is turned on?

2. Will iPhone turn on with no display/digitzer/camera cables + home button attached?

What can be the issue? It was working fine before, but meanwhile (while i was waiting for the new screen) i had it powered on - with no screen and top attached. Which means it has lost it's entire power.

I replaced my iphone 5s screen and afterwards I have this systematic issue. Every time you hit the power/home button to wake it up, the touch screen is unresponsive. Simply pushing the power button twice (sleep then wake back up) results in a fully responsive and functioning touch screen. This occurs basically any time the phone has been asleep for longer than a minute - I haven't systematically figured out the exact time.

Does anyone have any ideas what is going on? I have turned the phone off and back on, same issue remains, and it has persisted for the last week.

Thank you for any assistance,

Jake

When i had to put the EMI shield back on i accidently used the 1mm longer screw for the buttom left hole (so i guess i made some minor long screw damage to the Logic board and broke some traces. also heard a little noise when screwing the last mm of the screw) :(

And now it doesnt show any picture on the LCD at all. Have anyone experienced that before?

Read something about that it sould be able to get fixed here

But my phone doesn't show any blue screen.

It also viberates every few seconds when it's in a charger (only after newest software update).

It is getting detected in iTunes.

I attached a picture here so you can get an idea of the damage (red circle marks the screw).

I would really like to get it repaired but the problem is im from Denmark and it's not possible to find any experienced person to make the repair here. So i would like to ship it to a repair business nearby country like UK/Germany if it could get fixed.

Any1 know any business that might be able to complete this repair?

I have read that this error is related to USB cable or/and USB port problems but I have tried with 3 different cables and with all the USB ports in the computer and the 2003 error is always there.

Do you know any solution to this?

Do you think it could be a battery problem?

I have had a few baths in which I brought my iPhone in but I have made sure it hasn't gotten wet, however a few drops of water fell on the screen and possibly onto the volume button or something. And yes, I have stopped bringing my iPhone into the bath...

Help please? :)

Here are 2 angles of where they belong on the board, with circles for each

I looked up the logic board layout, and found that the 3 components that broke off were called : Q3, U3, and DZ101_RF

I am curious to know if my iPhone is worth saving. I am very handy and deal a lot with computers due to my profession but have never repaired a phone. I enjoy learning so this should be fun for me. From what I can tell MOST essential components are relatively intact, The battery I am pretty sure is toast though. I am in no hurry to repair it considering I already purchased a new phone. This will be more of a tinkering project.

Here are my questions. (I have included photos also.. So you guys be the judge on what you think is the best route to go.)

1. Is this even salvageable?

2. What tools would I need/parts?

3. Has anyone repaired a phone this damaged? What issues could I possibly run into with this type of damage?

4. What would the estimated cost be to repair?

Thank you, any help would be greatly appreciated.

P.S. No, I did not break my iPhone attempting the bend test.

The charger blew up (black scorched and totally melted) and flipped the circuit breaker. I am guessing the capacitor in it exploded.

The iPhone originally had a charge but does not turn on now - just a completely unresponsive black screen. It wont charge with a wireless charger either.

Any ideas on where to start? I can't find any guides on the internet for this situation.

I asked around and they told me it's because of the front camera theirs a sticker that needs to be intact with the camera ( if you don't heat it up good ) can this be true ? Maybe it fried the front camera and it's not letting it turn on ? Anything helps guys thanks !

i have an iPhone 6s, which shows ,,Device unknown'' after selecting language and country . I can not activate it.

If it powers on, it takes about 3 min, until the apple logo dissapears and until i can choose the language.

iTunes does not recognize the iPhone, no matter if i try to put it in recovery or DFU mode.

iTunes and the iPhone has the actual software. I also tried to change the battery, but it didn't help.

Thanks in advance for your help.
