After replacing my broken screen and LCD if I'm inside a building or somewhere that I don't usually have full signal I now have almost none to no signal now. I'm guessing that it has to do with an antenna or something. Can anybody tell me where to start looking to fix this issue? It is annoying because now my service area is limited. Thanks in advamce for any help that you can give me.
Same problem here. I've replaced the antenna cables with new ones hoping to sort out this issue, but it didn't.
This phone has gone from being very reliable to almost unusable for making calls now.
Anyone know where to look for an answer?
Make sure you have them plugged into the correct places.
They are. Triple checked.
Mine weren't even though I swore that they were. I had them crossed at the top connections.
Looking at the phone, the black cable plugs into the right side and the gray cable plugs into the left side. On top and bottom. My cables are not long enough to swap them around.
You would think so. Looking directly at the wires the one that is connected on the bottom left connects to the top right. This should be the grey or the longer of the two.
That's odd, this picture shows the black cable staying to the right and the gray cable staying to the left. I have it the way it is shown in this photo.
I will pop the back off mine later on and I'll let you know what mine looks like.
Thanks, I would appreciate that!

Hi!
I just replaced the screen on a wizard because the old one got smashed.
Anyway, I connected it up, re-assembled everything, and turned it on. The screen stays solid white, and then goes dim once its presumably finished booting.
The weird thing is, I can still use the touch-screen because if I click at the top left, I can hear the menu drop down, and can select items from it!
Any ideas what I've done wrong, if anything?
Ive triple checked all the connections and it all seems okay!
Help!
Thanks
two suggestions, that might aid diagnosis, feel free to shoot them down in flames.
Have you connected the device using pocket pc controller or similar software application?
Have you tried hard reset?
Do keep us updated.

I had a simular problem replaceing my screen. I know you will say it looks right but it isnt. the ribbon cable that the lcd fits into isnt properly seated the tabs that stick out on the sides of the ribbon cable need to be fitted all the way up against the fitting the tabs on your arnt pushed in resultin in a volatge connection but no video.
i replaced my kaiser screen and the only thing that i got was a white screen so i was wondering if someone here had the same problem and got it working properly again.
Check on the Kaiser thread. Someone posted the same issue, and I think his screen connection wasn't tight, and it came loose.
don't think thats the problem connection seem all okay but if you could find the thread link please post it.

thx but no one posted a solution...
Provide more info...
did it turn white immediately after the screen install or did you try to install a ROM or what?
If white right away, then I have bad news for you... you will need to recheck your connections... all two of them..., I know it is pain in the Ars but it is needed.
If you attempted to install a ROM and then the white screen, then it is a Software issue. To track back, do a hard reset and see if you get somewhere. Look in the wiki section for hard reset instructions.
yeah it turned white immediately after i installed the screen like in the picture

Ribbon Connector
I had the same thing happen with my wizard a while back. Make sure the ribbon connection is in all the way. Assuming the ribbon on the kaiser has the same type of connector as the wizard, there is a piece of plastic that you lift up to unlatch the ribbon, make sure that bracket is open, then stick the ribbon in all the way (it went in farther than I would have expected) and then push the little bracket back down to clamp the ribbon down to the leads. Make sure the ribbon is perfectly perpendicular to the clamp also (not entering the connector crooked). And maybe check to make sure that you are routing the ribbon correctly, where it is not being pullde out or loosened when you open the screen. I'm pretty confident that your problem lies somewhere in that ribbon connection. Anyhoo, good luck. I'd take you some pics but I just gave my wizard to a friend & I don't wanna open my kaiser. Yet.
i have a similar problem, any ideas on this?

hmm i think i already tried it. i even putted a new ribbon in but it doesn't hurt to try it again...
problem solved screen wasn't the same type as the old one a repair store fixed it. so the number on the screen gots to be exactly the same as the old one
My dumb butt child was sucking on my phone a couple weeks ago and caused the LCD to short out or something. The phone still worked and if I used a bright light I could shine it onto the screen and barely make out what was on the screen. It was booting properly and I assume that if I could make out the menu options the phone would still function. I assumed that she shorted out the LCD so I ordered, received and replaced the LCD tonight. Apparently this was not the problem, sucks to be me. I do think there was a problem with the touch screen portion already which is now working properly again but still I can still not see the screen for crap. It's like the brightness setting is on 1 or something. If I use a flashlight I can make out the screen, use the stylus and operate the phone. When I was replacing the LCD I noticed that the two circuit boards to the north and south of the LCD seemed to have a bit of corrosion on some of the tiny chips. I used an alcohol swab to clean the area off but that didn't make a difference. I am utterly convinced that the motherboard is fine since it seems to be well protected in the case and not easily accessible to moisture. I see no signs of corrosion on the motherboard like I do the two circuit boards around the LCD area. I noticed that there are only two contacts on the LCD one of which is a cable that plugs into the south circuit board just underneath the front panel key pad. Just to the right of that cable connection is where I saw signs of corrosion so I wonder if that board is the problem.
The computer tech in me says that I could be swapping parts all night before I get this right. Since the LCD plugs into that board, that could be the problem, there is a ribbon cable that wraps around the back of the LCD which also seems to make contact with the LCD which could also be the problem, that ribbon cable plugs into the north circuit board, so that might be a problem and finally, the ribbon cable plugs into the main board so that too might end up being a problem.
Can anyone take a guess as to why I might be seeing such low contrast/brightness from the LCD? I have already adjusted the brightness setting in the menus. I think it was called the backlight setting, but I moved them to the far right with no change. Again, this is a near pitch black screen that is only visible when I shine a light onto the screen.
i haven't taken my tilt apart but as a computer tech repairing broken laptops etc i know your problem.
as for laptops, there is a little inverter card that powers the backlight. its connected to the display unit by 2 cables (same as with my digital camera, rip ) and this boards are really weak / vulnerable to moisture...
so most likely this board is damaged...
That sort of explains what I think is going on too. Take a look at this cable (apparently it's clickable and will grow slightly in size to give more detail):
Let me explain the cable. This fits directly behind the LCD. The LCD comes with one flat ribbon cable and it plugs into a port on the right side of this picture. On that right circuit board if you notice the top left portion of the board there is thin black slot which is where the LCD plugs into if I recall correctly. There is another cable that plugs in just to the right of that jack from where I forget actually, lol. Once that cable is flipped over the bottom keypad on the phone sits right on top of that board. In fact on the other side you can even see the contacts for the outside buttons. The buttons in question would be like the green phone and red phone, the "e" shortcut and pretty much all the silver external shortcut buttons. Getting back to the cable, you will notice that in the middle of the cable there is a rather wide connection and that is the one that plugs onto the motherboard.
When I was replacing the LCD I spotted two sources of corrosion on both boards. The more plausible culprit was about 1/8 of an inch away from where the LCD plugs into the right circuit board.
I sent HTC an email seeing if they would help to which they told me to send it in. I have no intentions of doing that. I already know how to disassemble and reassemble the phone at this point and I already have 35 dollars invested into a new LCD. I am not about to spend 250 bucks to have HTC take 3 weeks to replace that cable. After some searching last night though, I have no idea where to get the cable. It seems that all the normal parts places on the web want 90 bucks for this cable, but at the same time they want 120 for the LCD. Obviously prices have dropped some because I was able to get the LCD new from ebay for 35. I just need help finding a place that will sell me that cable at a reasonable price.
Now that you have looked at the cable and that board, do you think it's possible that the right board could be the back light inverter that you were mentioning? If that's truly the correct board then it would make since that there is something wrong with it since I saw signs of possible damage and the LCD does work, just not strong enough to be seen with the naked eye. Since these things tend to work much like laptops do, I am leaning towards the possibility that you totally know what your talking about and that it would make since that this is the faulty part.
One other thought, the backlight is the piece that increases the brightness of the LCD right and not just some sort of overhead flashlight or something, correct? The term backlight almost implies a different part but I am pretty sure it's the term used to describe the brightness of the LCD in this case. I just wanted to make sure we were on the same page here.
Any additional thoughts?
Thanks
okay, to be clear about this. i am not 100% sure, if the backlight on the kaiser works the same way as the one on my IBM Thinkpad T41.
tl;dr; i don't know if the kaiser actually has an inverter board.
as for the cable: if you found a bit corrosion on both boards, i'm pretty sure that the reason why your backlight doesn't work.
about the last part: yeah, with "backlight" i mean the unit sits behind digitizer and LCD and increases the brightness of the lcd so you are able to read everything on the screen. i don't mean an overhead flashlight
btw, i just found this one

selling the cable / boards or about 90$
<edit>
disregard that... i noticed that the boards allways come with that cable assembly.... and cost about 90$ everywhere... will keep an eye on that.
</edit>
I'm going through the same thing. Did you ever replace that piece? Please let me know because it sucks to not use this phone.
So...I took apart my Nexus One to clean the dust from under the screen. I've done this before, but it back together and it worked. But this time, after putting it back together it wont power on. I sometimes get a vibrate after pressing the power button. One question though. This time I noticed that one end of the coax cable on the left of the phone is broken and there is no plug on it. Would this be the problem? I don't think it should though since I'm guessing it connects the GPS antenna to the rest, and I dont use GPS on my phone. Any help would be good.
EDIT: I think I didnt connect the LCD good enough.
The co ax cable must be connected to the logic board. If it won't click in connect it then secure in place with a small piece of tape.

As I said, the top plug of the coax has been ripped off.
Do you know if that's the problem?
Again, when I push the button it vibrates like it usually does on boot, but doesn't show anything on screen.
I pulled out the board again, trying to find the problem.
EDIT!!!! I just noticed on the LCD ribbon cable there are a few bent pins. I think that will be my problem. I'll get it back together in like 15 minutes and report back.
EDIT 2!!!! So yea...two of the pins came off, and are way to small to find. Guess I need to order a new LCD.
Crap, new LCDs are $60+
I turned on my phone earlier to notice that the screen was suddenly completely white at full brightness whenever it was on, still touch responsive as I can hear it. This is happening immediately upon boot, not even showing the Samsung nor AT&T logos, so I believe it is a hardware issue. Has anyone else had this happen? If so, is there a solution short of getting a replacement? Maybe tearing it down and reseating the connector or something? I don't know, just a bit upset and rambling, sorry
Tore it down and undid and reseated every ribbon cable I saw, didn't help. Ordered a replacement should get it in a few days, might sell the old one for parts to recuperate some of the costs or maybe pick up one of the media docks that does TV out and USB host as well as charging, see if I can convert it to a set top box, assuming the dock will work without any setup on the phone itself
