kaiser repair problem

so i cracked my LCD a couple weeks back..today i recieved a replacment LCD from htclcd.com ...followed the instructions from the site..now i turn on my phone..and everything works perfectly..exept it cant find a signal anymore...seems to recognize the sim card...everything else works fine..just no signal...where could the problem lie? any suggestions? thanks in advance!

I would be very suprised if the lcd has caused this issue, have you tried a manual network selection yet?

It is likely that you have accidently disconnected or damaged antenna or connection to the antenna. I'd try to disassemble, examine visually that all parts are OK and reassemble the phone.

thats that i was thinking..but i dont know where the antenna is located in the phone so i dont even know where to begin to look

Hi stolli,
please let me know if you could repair your phone I have the same breakdown for the same reasons.
thank you

is there a way to replace the keyboard or fix the problem somehow?

It may just be the Keyboard FPC connector is not inserted firmly enough. See pages 21 and 33 of the manual.

Hi, it seems that all lugs looks good, but it is not easy to see if contacts are OK, Wlan, GPS, Bluetooth are OK but not GSM
I tried to connect via VOIP, voip is connected but i always have no services??????

green led is flashing, is it for GSM, wifi or dial?

did you insert the lugs from the battery side first? the contacts are the gold pieces...if they are intact they should be fine..when you put the tilt backtogether did you put it together firmly, tighting all the bolts? also make sure flight mode isnt on

Yes, I also slightly recovered "lugs" that looks a bit twisted.
Do you with one is used for GSM?

I changed several times mode phone to flight to test the line but still nothing.
I will work in Paris tomorrow, I'll test the gsm signal will be better , but on my other phone with the same Sim all is good.
Thanks.

the reason why the lugs are neceassy is to hold the casing firmly down so the gold connecters touch...make sure that the casing is tightened firmly down..and maybe lift the gold connecters on the main casing a little bit so they stick out more (thats what i did)..make sure not to break them tho..

The problem must come an other part, the lugs are good.
I had great difficulty connect to GSM in Paris yesterday.
I have disassembled it again checked and reassembled but nothing new.
thanks for your help.

Hello
I killed my Kaiser by flashing a Touch Diamond ROM to it.
Sent it to repair service and they say the Mainboard needs to be replaced,but the price for repair is ultragious .
I realy need the device,it was a big help in my confused life style.
Can anyone tell me how can i fix it myself. Or where i can buy a mainboard. Or where can i send the device to repair for a cheaper service?
Thanks in advance for all your help guys.

Some of the keys on my keyboard are dead, any clue? Disassembled several times with no luck...
Doh... looks like the keys are gone.
WOW! It works, when I gave up! Ironic! DD

Ok, so if there happens to be others with the same issue.
Make sure when you connect the golden keyboard connector that the black thin line on it gets positioned exactly where the brown lock ends.

[Q] Wifi not turning on

I bought a galaxy note n7000 from a friend. It has android 4.1.2 installed. build number is n7000XXLSA.
the problem is wi fi doest turn on.I mean whenever i want to switch it on it seems its trying to get on but fails. The green light never shines on it.
The problem i cant understand lies with hardware or software.
Sometimes the wifi gets connected and then it works like a charm. But most of the times no matter how hard i try it never gets turned on. Ive tried factory reset, restart, removing batter and memory card nothing seems to work. I tried wifi fixer app but nothing happened.
I am not very technically aware of rooting, and how to modify it. But i think from what ive learnt is it is caused by updating from ICS to jelly bean 4.1.2
I dont know whether my phone is locked or unlocked, rooted or un rooted cause im totally new with phone.
Please someone guide me how can i rectify this problem, I dont mind taking risk with my phone but wanna know what all should i do to solve wifi issues.
Plus i also would like to update to 4.2.2 kindly let me know step by step starting from basics how should i go about it.
regards

Go to settings and wi-fi and there when you turn on the wi-fi it should show the your network which is remembered and show read something as authenticating obtaining ip addreas and such.. Just select your netwirk once and click on forget and then try to connect again putting in your network key.. To check if you are rooted or not: you must have an app which saya superuser or su.. You can also download root checker app from market to see if you are rooted or not..

I suggest you move on to stunner rom instead. It has all the features of the Rom you are currently using. Stunner is, if I've got it right, built from parts of PA.

Solution found
sorry for the long post but this will work
After three months of dealing with the same problem on my GT N7000 as nashbloom i have found a fix to this wi fi problem.
And I mean WIFI problem. this is not a matter of obtaining a connection, this is a problem where the wifi wont switch on at all.
It trys, to switch on (sort of transition phase) than freezes or fails and turns off again.
Just as I was preparing to back up my phone and take it in to samsung the next day I found a post on a you tube clip saying to clean corrosion built up on wi fi antenna.
Desperate, I tried it,
1. remove 9 screws (dont worry they are all the same size) on back and remove cover
2. with a cotton tip/bud wipe corrosion in top left hand corner (looking at the back of the phone)
3. not knowing what a wifi antenna looks like and having seen no corrosion i wiped everything including the cover.
4. i removed a few connectors and put them back in place.
5. put everything back in place and problem was instantly fixed
I did this two days ago but have had one time where the same problem reoccured, otherwise, perfect.
P.S. This is proof that this is a hardware problem not a software one, but i kind of knew that when i changed every wifi setting on the phone several times

will try these today
I will try these today as soon i get home.. i been looking around for a fix.. I hope these will resolve it

Two months now with this silly wifi issue. Did this trick help with your phone?
I did everything possible trying to solve this problem but to no avail.
Wiped anything that could be wiped on the inside, replaced the USB port board, but wifi is relentlessly disconnecting at random times.
Any idea?

I found something weird.. when the phone is without the back cover wifi works perfect. when I put it back the wifi goes off. ???? I really do not know was wrong with the phone.. (i do not use it anymore).. the only guess is that the back cover pressure something to the board and disconnect the wifi.. I really do not have a explanation.. take care..

Like everyone here, I was having the problem with the greyed out WiFi and also got some practice with flashing firmwares and doing factory resets, backups and restores, all in vane.
I found this post and decided to give it a try, also checking a YouTube video about how to open the GT-N7000
My phone did not have any corrosion, but after reconnecting, i.e. taking out and plugging in again, all connectors to the main board, the WiFi came back to life. That was two days ago. I cannot say it works like a charm, after a couple of hiccups, I just don't trust this phone anymore and I think I had the greyed icon once yesterday when I tried to switch off and on the WiFi.
This experience led me to believe that there is something with the connectors that got loose after my phone has fallen off my pocket a couple of times. If you wear pants that were not designed to carry phablets, this might happen to you as well.
Anyway, a big THANK YOU to atchya for the idea of opening the phone.
Cheers,

[Possible solution]Follow the link how to clean up the connectors
Yeah above solution works. This Is the only way I got my wi-fi to work. Tried re-flashing Rom (downgraded and upgraded) even re-flashed Radio. Finally cleaned up , unconnected and reconnected cables, so far works fine (no greying out of menus etc.) . Will keep you posed
edit: Open the photos in different tabs to see the antenna connectors, they are tagged you will know exactly what to clean

HTC One dead? Help please! :(

Right basically my speakers started acting funny, crackling at the bottom no sound at the top. So thinking it might just be some metal and dust in there i decided to open it up which went quite well i cleaned it all out and put it all back together. I went to turn it on & nothing, just flashing back & home so i opened it back up and double checked the connections and things they are all fine, i turn it back on & nothing! just the flashing back and home. It shows the charging LED. I have tried the power + vol down to no avail so i'm hoping one of you great people can help me!?
Thanks:highfive:

So it looks like you performed a self repair and opened your phone right? And it seems like you, in one way or another, tampered with the screen involuntary.
I would suggest going to a repair shop and seeing if they can help you. The HTC one is a hard phone to fix and self repairs aren't ideal.

[Q] Help Please - HTC One Water Damage Urgent

Hi Guys,
I know this was a bit of a stupid thing to do but the other day I accidently dropped my phone in to a small amount of water, enough to submerge my HTC One. It was in the water for a second as i pulled it straight out. It seemed to be working Ok still though. It was going a little crazy like when i opened Whatsapp and opened a conversation it would open the persons profile or toggle attachment options and it kept opening the AccuWeather page when i was trying to scroll apps. My speakers and sound was also very faint for a while as well.
I plugged it into my tablet via the USB port the LED light came on and it charged. In the night i woke up and the phone was off, so i hit the power button it came on as normal but was still going a little crazy, so i left it on charge and went to sleep. The following morning i woke up it was still on but still toggling things, i had to keep turning the screen off and then on again to be able to write a message or make a call before it started to toggle other things, but the speakers had gone back to normal and the phone seemed to be sorting itself out. Then while in the middle of a call the battery died and now i cant charge it. It has been on charge and in a bowl of rice all night and it still wont come on, theres now LED light, the computer has stopped recognising it, it said at first an unknown device was plugged into the USB port now it doesnt recognise anythings plugged in.
I really need this phone to come on soon I use it for everything, work, travelling, holding documents etc i really don't want to have to send it away where it will all get wiped, some of the stuff I haven't had a chance to back up yet. Any advice would be gratefully received, if you get it to work I am happy to reward in some way.
Many thanks,
Hollie

It's probably totally fried. The rice trick works best if you turn it off and do it straight away. If you left it too long the water has probably had time to seep through. Sorry I think it has to go in for repair

Not necessarily fried! Take out any takeoutable parts.
Put alll parts in a warm dry place (airing cupboard) and LEAVE IT ALONE FOR A DAY OR TWO.
Many phones have been saved this way.

XZ3 WIFI and Network connection problem

Hi Guys, could you please help me out? A few weeks ago my XZ3 started to act weird. It working perfectly, and after a random time, suddenly its losing both the wifi and mobile network connection (bluetooth is OK). Sometimes a simple restart solves this, but other times its not helping. I tried factory reset, but the problem still occurs. Could it be somehow software related or it must be a harware issue? Any information could help a lot! Thank your very much in advance.

issue may be in chipset so repairing is hard.
I gave it to seller then he sent me another xz3 phone.
now I don't have such issue.
I think it is a manufacturing issue, few phones has this same issue in all Xperia models like xz2,xz3, xperia 1....

i got it fixed from a local repair shop. The issue is caused due to some loose components on the motherboard. There are a bunch golden pins around the edges of the main board, the repair guy called them "signal boosters". i don't know what they're actually called. They're all connected to two main signal boosters right in the middle of the motherboard.

UPDATE: it's the plastic middle frame of the phone!! i finally figured it out.

I'm sorry it wasn't the middle frame either. the issue came back after a couple of weeks, mostly when phone got hot under heavy use. i figured when i pushed hard on the side of the phone where sim card lies, the phone would lose signal for a sec or two and then come back to normal
I finally managed to fix my phone somehow it hasn't dropped signal even once in two months. i haven't been able to pinpoint what exact component is malfunctioning that's why I'm going to list every little thing i did..
it's definitely one of the metal contact points on the edges of the motherboard near the sim card tray that connect with the phones casing to boost the wifi and 4g signal. i put a small piece of medical tape on top of each contact point near the sim card tray to completely block them off. ( I've marked in the attaced pic exactly which contact points you have to block )
I've also removed the plastic dummy sim holder that sits just below sim card tray to fill the gap between metal sim holder and phones body. put a piece of paper medical tape there instead. put a small piece of paper in the top right corner of phone housing so that motherboard would stay a little above the housing when you screw it (see pic)
make sure motherboard screws aren't too tight
Don't worry it has little to no effect on phones signal reception, you're only blocking the sub antenna

So what you did at the end?
Any update on the matter?

I was able to partially solve my problem with my phone, I took out the black antenna frame and very carefully placed transparent scotch tape (because it´s thinner than medical tape) in all the contacts that are marked in red in the atached picture but now I´m thinking that I shouls have placed tape also on the places marked with green.
So what change I experienced on my phone with this method?
well the phone now has Network and wifi signal all the time and very ocassionaly it does lose the network and wifi signal for a second but when this happen the phone does not say that there is no sim card and does not freeze and restart, it just recovers signal by itself and I can continue using the phone.
