Help with Wizard repair diagnostic

My wizard was slammed with a trunk lid. The clear screen is fine, no cracks, the housing has a scratch where it hit the lid. The lcd screen is half ok. Now I said all that to say: I bought a screen, here is the link:
http://cgi.ebay.com/ws/eBayISAPI.dl...em=&sspagename=STRK:MEWNX:IT&salenotsupported
Now that I have this, it doesn't look like this is what I need.
Here is a pic of the phone turned on.

I can use it with what I can see. So it works fine, its the window that I can't see that is the problem.
Can someone look at this pic and tell me what I should have gotten?
Thanks

Thanks, I couldn't get any audio so it was hard to follow. Did you get audio? Is there anywhere else I can look?

My understanding is, You got a wrong part. What you got is a digitizer, it is the one used for touch only and will not be suitable for the type of repair you need. What you need is LCD. The screen on most resistive screen devices consists of 2 parts - 1 LCD and 1 Digitizer attached to LCD by a layer of fine gel and connected by a flex cable, then the whole assembly is connected by a flex to the mainboard.
My recommendation would be to purchase the entire assembly, get a service manual and replace, however, if you had problems deciding what part you need to repair your Wizard, I say take it to the professional.

The way someone is opening and attempting to repair their Wizard on that video is what keeps me employed. Watching someone open their device with screwdrivers and then attempting to re-connect the flex and forgetting half of the screws gives me the creeps, not even sure whether to laugh or cry. Would love to see the repair actually working, rather than someone claiming they found the way to do something without demonstrating any result.

Broken Screen on my XV6800

I dropped my XV6800 on a curb yesterday. The picture on the screen is fine, but it looks like the touch screen cracked and now no longer works. The phone won't even let me unlock...don't ask why I locked it after that happened Anyway, I can't do anything with it at all now except receive calls.
What is the cheapest and/or easiest way to fix this? Good source for parts etc..
Thanks!

use mymobiler on computer to unlock and such. But a new touch screen off ebay and put it in.

My Mobiler won't install because I can't unlock the phone to allow it to install. I ordered a screen from eBay.

hmm i didnt know it wouldnt install when locked. Does it go to locked after a restart.

Yeah, that's the first thing I tried.
I've been looking at the instructions on taking it all apart. It is a little bit intimidating, but I suppose I've done worse.

Lots of Screws
I had to replace the screen on mine a while back. It is actually pretty easy. There are just two things to remember
1) There are a lot of screws, remember which order you took them off in and which hole they go into
2) Nothing has to be forced apart, everything has screws or tape holding it. It is okay to take off the tape, and if the tape doesn't go back on it won't hurt anything.
The screen connects to the motherboard by a thin, flat plastic wire. DON"T JUST YANK THE WIRE OUT OF THE CONNECTOR!!!!!!!!! The connector has a little flip up on the end of it that allows the wire in and out.
Good Luck

Open the slide out keyboard and type in the password! I did that one time just to see if it works. This will solve the lock portion.

Well, I got the new touch screen, cleaned the shattered bits out of the old one, cleaned it all up good...changed it out, put it all back together...I must not have gotten the cable seated right.
Also, as for typing my password on the keyboard...no password.

Final update:
I got it to work.

How difficult is to take apart an HTC Ozone?

Hi all,
My wife spilled a glass of beer on my PDA, and now the top front buttons don't react like before. Sometimes you don't hear the 'click' and you can feel like they got stuck.
The keyboard looks fine, so the problem is only the with the top buttons at the front of the PDA.
Have anybody tried to take apart this PDA? Would be easy to open it and clean everything before putting everything back?
Thanks a lot

I completely soaked my Ozone about a week after I got it... knocked it in the sink. I like to think that I was among the first to void my warranty, Lo..l?
The phone is really well constructed for what you need to do. All of the critical electronics are very well shielded on the board, nothing difficult about separating the board from the case.
Six 'star drive' screws on the case (that's where the warranty sticker is), one tiny phillips on the board - board pulls up off of pins, away from the usb connector and Bob's your uncle. The keypad is not fastened to the case, pull it right out.
Watch the ribbon cable for the lcd - I would not recommend disconnecting it. there should be enough play to allow you to work. Make sure you're working in a really clean environment, and check the inside of the plastic lcd cover obsessively right before reassembly. If you're anything like me that one little catpet fiber or cat hair or whatever the hell will drive you to take the phone apart again 4 days later...
Sorry about the ramble... it's late. Short answer is: Nothing to it.
Good luck!

Thanks a lot for your post. It was really helpful.
I will probably try it this weekend.
I'll post here the results
Cheers

So if I wanted to buy a different color keypad (dont like the green) it shouldnt be hard to take apart??...I change screens in Env/Voyagers a bit so have a little knowledge...

[Q] Epic Disassembly - How can I open it up?

I'm on my 3rd Epic, and this one is going back, too.
Before I send it back, I'd like to disassemble it. I think that the current problem (speakerphone returns static to whoever I talk to) is a soldering issue and may be easily debugged and fixed if I could open up the phone.
Opening up this guy is not easy.
I can remove the visible screws.
I can remove the two screws hidden under the serial number sticker / battery mat.
Even after removing these screws, I can't get the back plate off.
How do I do it?

Opening it voids your warranty and you will be unable to return it if your repair fails.

It only voids your warranty if they can tell you opened it. I haven't run into any tamper-proof stickers.
So do you know how to get into it farther, or were you just poopoo'ing my attempt?

http://www.chipworks.com/samsung-epic-4g.aspx Shows some pics of it disassembled. Maybe it will provide some insight as to how to open it, and maybe not. Better than nothing. Try searching Samsung Epic teardown and digging a little deeper than the first page.

Searched disassembly, not teardown. Thanks.
The link actually helped.
The Epic has 2 microphones?

start up at the top by the power button and use something plastic to wedge between the pieces. DONT user metal, it will scratch or break something.

I've found a teardown picture that illustrates the difficulty...

The problem was the two tabs. I didn't realize how long they were.

There are clips where the back casing sticks to the silver band around the phone. You have to use a thin flat head to separate it. Be careful since the silver band is made of plastic and will crack if bent.
I had to take apart 2 Epics and swap out a faulty keyboard with another one before returning it.

Once I saw how the back cover was snapped on (wide indents that snap to the silver), I was able to remove it. I used a credit card, sliding it down from the volume button, parallel to the phone. Every so often, I'd use the card as a wedge to pry the top off. Eventually, it snapped open.
Unfortunately, I am unable to find a problem. The main microphone works. It just doesn't work in speakerphone mode.
Oh well... I'm on my 4th Epic. I'm holding off on returning them to Amazon. I'll have 3 of 'em sitting around in case I need to make a FrankenEpic.

Do you see any way to tighten the screen slider?
Sent from my SPH-D700 using XDA App

Hey, if/while you're still in there... do you see a MLF-type chip (these are the ones that look like a plastic box with no visible pins because the metal pads are entirely on the underside) that's approximately 3mm x 4mm that has something like "FSA 9480" (or just "9480", or even "Fairchild") written on it? Probably near the USB port? I've read about its existence inside the Epic (and all Galaxy S models), and it seems to be getting enumerated by the kernel during bootup, but I didn't see any actual chip bearing the name in any teardown pics I've looked at. I'm starting to suspect that the "9480" *might* just be IP that Samsung licensed from Fairchild and incorporated into one of their own ASICs (with "9480" being the "IP name" of the chip Fairchild sells as the 9280), but it's really hard to tell.
For anyone who didn't see my other post, or the thread in the I9000 board, the FSA9480 is a USB switch that enables the USB port's two data pins to be repurposed for a) serial UART Txd and Rxd, b) Stereo audio left and right out, c) mono headset with audio out and mic in, and d) JTAG via a special interface called "JIG" that's kind of like Atmel's Debugwire and serializes the various pins of a JTAG interface. It's not actually using USB... it electronically disconnects the two pins from the USB interface, and connects them to the audio/uart/JIG pins elsewhere inside the phone.
Also, if you can see anything that resembles a manufacturer or part number for the USB port, that would be awesome. I know that someone, somewhere HAS to make them, but trying to find nonstandard, offbeat connectors in the millions of items sold by companies like Digikey, Arrow, Avnet, Mouser, etc. is like looking for a needle in a haystack unless you already know the exact part number you're looking for.

didnt really llook too hard, but i didnt see any

How difficult is it to replace the entire screen/lcd? Is it possible to easily remove the entire top off the slider and replace it?

Yes its rather easy you take off the back cover use something like a guitar pick to pop the back snaps apart then from there undo the connections to the main board remove it a few more screws under the sticker and one under the main board i think there is a ribbon cable you have to be genital with they rip really easy also make sure its put back the way it needs to be.. when replacing the screen there are tear down guides all over the new that show it in detail...

G2 unresponsive screen after replacing charging flex cable

Hello
I can't charge my LG G2 D802, so I ordered a charging flex cablefrom ebay.
After replaced, the phone charges well, but the screen is almost unresponsive.
And it's very interesting, because if I replace to the old one, everything is the same, almost unresponsive screen, not like before disassembly...
Any idea what to do?
Connectors and everything looks fine, but I can't believe touch screen stop working after disassembly.
Please help if You could...
Thank You!

You disassembled the phone? If you didn't put all the components back in place as it comes from factory and taped, then there could be grounding issues. There is a set of transistors next to the lcd connector and above the charging port, make sure it's touching the golden pad on bottom and is taped.
Or else it's a bad cable, bad grounding somehow, moisture issues etc etc.

I think You're right.
The set of transistors may not connecting well.
Can I use processor pasta to glue it back?
Or just some simple tape from above?
-----------------------------------------------------------
So I cleaned it with alcohol and the original glue getting stronger, so I put it back to the right place and put some tape on it.
But still the same.
Do I have to put tape on the cables above the battery?
How could I find where is the bad grounding?

No i don't recommend to put thermal paste therez if it conductive it can short nearby components and can also get messy, it is only for using on chips. I suggest you use double sided tape, but do it strategically so that it leaves a small portion open for the golden pad to make contact. And after that you put nonconductive tape on top of that. Make sure the metal part of the white cable nearby is not touching this area, or you can also put tape between them. I suggest to put tape on the lcd connector as well.
Whenever this problem arises, and if you have trouble to fix it, an easy way is to disconnect and reconnect the battery after a few seconds, should work ok.
You can also purchase a new one like this, look for your device model - https://m.ebay.com/itm/183023879505

Seems like the set of transistors well connected now and I put tapes on it and on the screen connector as well.
And I reconnected the battery too, but nothing happened.
It's the same as before.
And if I replace the charging port flex cable to the old one, it's the same too, but before disassembly it works, but the problem was I cannot charge the phone.
Any other idea what should I do to fix it?
I cannot choose D802 on the link You gave me...
Anyway I think this one and the old one is fine if it's about the touch screen, have to be something another...
