I somehow managed to crack the display on my cell phone, a Sony Ericsson P910i, so I was searching the net for instructions how to do replace the screen. Sadly, none could be found so I decided to write about my own experience.
First of all, I'm a silly politician. If you still decide to follow my instructions then you're probably pretty mad. Needless to say, I do not accept any responsibility what so ever for what will happen to your phone. If you decide to use my instructions, it is entirely up to you. I can't emphasize this enough.
You really shouldn't go this far with me, but ok. You have been warned.
This is what my phone looked like
Tools needed for this operation:
One screwdriver. I found one in the box the phone came in. Get the box and check there.
One needle
One spare LCD-screen. Try E-bay or something similar, or maybe this place
Turn the phone around. It should look like this:
Now, remove these:
And remove the battery lid, the battery, the sim card and memory stick. It should now look like this:
Unscrew the 2 screws using the screwdriver and the 2 screws at the bottom of the phone:
Open the flip and gently open the casing. Now be careful because at this point I discovered that 2 small screws fell out from the phone, showing in the picture below. I never found where to place them again. If anyone knows where these 2 screws belong, please tell me.
It should now look like this:
Carefully, flip the screen on its back like this, and unscrew the screws as indicated:
Now it will look like this. Try to remove the circuit board from the casing. I had to use minor violence in order to do this. Be careful! Now, at this point I never thought I would be able to get my phone back in a working order so I wasn't very concerned about taking pictures. I couldn't see the point of this at that moment 
Anyway, the screen is connected to the circuit board as is indicated in the picture below:
However, and this is very important. The casing is also connected to the circuit board, showing here:
Remove the old display by pulling it straight up. Replace it with the new one. Replacing the screens is a straight forward process.
Connect the circuit board to the casing as was indicated in the previous photo, and screw all all the pieces back together.
When I first tried, the loud speaker wouldn't work, but once all screws were in place it started working again. My only problem now is that the jog dial button doesn't work properly, but I can live that.
This is the result:
I paid 600 SEK [less than 80 US$] for the screen. Going to a regular repaire center would have costed me about 1800 SEK [almost 240 US$]. You decide if it's worth doing it on your own.
Update
This came in the mail, maybe it's useful for some of you:
Well done for posting this info! I replaced my screen a few months ago, using this tutorial. Thank You!
However, a week ago, my touch-screen cracked. I'm wondering if the (some?) replacements are not of the same quality as the installed units. Anyhow, I decided to replace the touch-screen portion of the display. This is not for the faint hearted (as I discovered). The connector has to be soldered.
The touch-screen can be eased from the main display by carefull running around the edge with a precision blade - it may crack during the process, but it won't matter. I then used a drop of superglue (non-viscous) on each corner, just enough to seep between the glass and metal surround - and not onto the display face. The connection needs soldering, so I "tinned" (applied a fine coating of solder) the four new contacts on the ribbon. Holding the ribbon in position against the destination contacts. I just ran the iron over the ribbon itself, and the heat penetrated and melted the solder without frying the ribbon - it worked.
Hope this helps someone,
Grant.
Just want to say this has helped me a lot! My display broke, i ordered a new one (in the Netherlands it costs 150 Euro, about 180 US dollars) but it’s worth it!
Thanks for the tutorial!

This was Excellent. My phone has been broken for a year now. I finally found a suitable replacement last week (Nokia N70), but I still couldn’t let this phone go just b/c of a cracked screen. This is the only site I have seen that has even mentioned this issue. SE really needs to offer this part online. …Anyway, enough of my rambling (I guess it’s the euphoria from have found an option to fix my baby (p900). Also…if your jog wheel is still inop, you may want to make sure the ribbon cable is connected. It may have been disconnected when you disconnected the LCD. If this helps, it’s nothing compared to what you have done for me. Thanks for sharing!

Hi,
I looked all over the net and found your guide. I am assuming that it is going to be very useful to me. Well, I have a question. My display seems to be working fine, but, there’s a crack on the screen(touch screen rather) I went on ebay and found people selling just the touchscreen for 30 bucks and just the LCD for 100 bucks. I’m confused, can I just buy the touchscreen? Please tell me how many parts constitute the LCD and the Touchscreen configuration. If you have any pictures, they’d be very helpful. Thank you very much.

Chandru: AFAIK, the screen is just one piece. There is no easy way just replacing one part of it. There is no way I would consider trying to split it and just exchange the touch screen part. If I were you, I would try to get the whole package.

This was awesome. Ebay for the LCD $80 US. Your instructions made it all good.

A fantastic article which saved both my phone and an expensive repair job.
I bought an LCD from ebay for £60 and fitted it in minutes.
Thanks a lot

my screen isn’t broken, there are no scratch or digs, and the display is working fine, but only a certain portion of the touch screen is working, the unworking section is the top and bottom, more of the bottom, so only about 1/3 of the screen is actually working for touchscreen. In addition, there seems to be a severe allignment problem due to this, and it canno’t be fixed by using the calibration settings, because i am unable to click into the dots during the setup as it says too far from points. for instance, tapping the bottom right corner will effect somewhere in the middle right of the screen, making it impossible to even select the phone/gprs or bluetooth setting in the bottom of the screen.
I can’t even set the alarm or do anything much with this fone due to that problem. The only way i can get things done is connecting it via bluetooth and using a remote p910 software so I can see the screen of the phone from my pc and use the mouse to click around.
I’ve oped up the phone already and unmounted it according to specifications and mounted it back with everything working (jogdial,speaker) etc. nothing was out of place or got loose, so the problem I guess is damage to the touchscreen hardware untop of the lcd screen…
=(
i appreciate a listing of a several sites i may be able to find a replacement screen in good condition for the p910i. thank you.

This site is great! Thanks for the tutorial - I am going to try it.
I’ve got a p910i and my screen is also broken. I desperately need a couple of phone numbers from it. Could anyone please tell me what buttons to press to so that I can save all of my numbers to the sim card? I found a user guide online but it only says “go to contacts, do this, do that, blah blah”, but obviously I need to know what actual buttons to press.
Many thanks for any advice!

Hi, great instructions. My P900 also got cracked, but I couldn’t afford the whole LCD, and why should I if the screen itself is fine?
The Touch-Screen is not quite part of the LCD package, and I’m currently in the process of removing it. It’s a bit dangerous though, as the touch part is glued to the LCD part, and I’m having to go around slowely with a very sharp knife.
The connection of the touch screen is seperate, but again almost ( not quite ) integrated into the main connector, and disconnecting the touch-screen can also disconnect something internal to the LCD if not careful, but I was.
When (if, I still don’t trust E-Bay much) the new touch-screen arrives, I will try to remember to let you know how it goes.

hey man i have a p900 and p800 both look like yours. you bought a hole new LCD, was your lcd cracked or just the touch screen because im looking on fixing mine and the screen still seems to work but if you touch it the touch goes allcrazy. a new touch screen is only like 30 bucks for the p800 and p900.
Left by mike on August 7th, 2006
Well, if you manage to split the LCD unit to replace the touch screen, by all means go ahead. I wasn’t aware this was a possibility so I just went ahead and replaced the whole unit. The LCD still worked somehow so I guess I could have just replaced the actual screen but I really have no idea how to do that. Please tell me how it went.

Thanks for the tuturial, would have been absolutely lost without it. Had some difficulty in separating casing after unscrewing it. Used thumbnail to push back catches on side. Plus it was not that easy reconnecting the smaller plug-in connection on circuit board that links to jog dial (which seems to make it difficult to wiggle out the board in the first place using minor force). Used flat end of small screw driver to push it into the tiny socket with the circuit board almost in place. Everything functions fine now.
Thanks again

thanks this article really helped the two little screws that fell out are to hold the keyboard in place i think

Can someone confirm how to remove the connector portion between the LCD touchscreen and the LCD unit , which side to preserve and which side to pull out, and how to stick it back after adding new touchscreen , Am i to use some type of glue to hold this together in the end, This looks dangerous.
Left by vivek on September 30th, 2006
I removed the connector by slowly pulling it away from the LCD. The connector to preserve is the one that is attached to the LCD. I used a couple of precision screwdrivers. The connector seemed to be stuck with some kind of adhesive to the LCD connector.
Now I am stuck (no pun intended)
My problem is I have no idea what adhesive was used, I am unsure if regular super glue would work.
Any ideas ?
Left by Angus on October 22nd, 2006
I bought a seperate touchsreen and sucessfully split my old LCD from my old Touch screen but the connection between the OLD LCD and the NEW touchscreen doesnt work, i think it needs some ridiculusly presision soldering since when you remove the touchcreen you are actually ripping the original conection. no easy plugs.. anyone that has successfully done a touch screen replacement could give me a pointer. .. i now have a p900 with a disconnected touchscreen which is pretty much useless.

hy folks.
I’ve screw up my p910 in august last summer, somehow, I pressed it with a window when I was about to close it!
Since then the display is unworkable, so the phone became useless.
All this time (until today) I wass looking for a new display much cheaper or a used one because its very expensive at local authorized service.
Thanks to this tutorial I had no problems with replacing displays.
Only problem I had, jog dial wasn’t working, so I deseparate the phone again and push up contacts of jog dial button, get back all together and it’s important to pinch the phone well, on the sides.
Now everything is working properly. Cheers!

Hi,
Thanks for taking the time to do this tutorial as it saved my P910 handset. Ebay has by far the cheapest LCD replacements. Mine is a 19 GB pounds second hand and works perfectly. When separating the main circuit from the back case, did it carefully to avoid separating the second cable which made things easier. Don’t think it is a good idea to buy the screen on its own. Even if it is cheaper (just 4 GB pounds on ebay) and looks easier, the connections are too delicate and it might be impossible to connect them again.
Cheers.

one of two cables from touch screen was lose it’s difficult to see but if you press those connections and at the same time keep tapping your screen if screen response that’s it. just press peace of cartoon against it and it’s ok now

Thx for an splendid guide to disamble the phone… My problem is just the touchscreen… It stopped worked, opened it and when i run service tests the touchscreen worked 1 time and 1 time only… The “touchscreen contact” is held in place by a silly tape… Wondering if some of you guys know were to positioning the “contact”… Someone having an highres photo of the contact on the back of the screen?! Or a tip for a forum where i can find answears?
Thx again for the guide… Nice Work!
