Hi, I got the manual on how to dismantle the Uni. I have a question on how to remove the Coaxial cable (display) on the mainboard. Does it take some force doing it, coz I tried pulling it up and it won't budge. Please help.
Clem
figured it out...mods please close thread.
Sorry for digging up an old thread, but I have exactly the same problem. Can somebody help?
you need to peal back the grey sticky shield and there should be a black tab to pull (there are two plugs on the main board). they should come up fairly easily without much force.
Actually, if you tag on the gray silvery tape, it will pull both connectors loose. But you need to start pulling in the right direction - from the side opposite to the hinge up and towards the hinge.
Replacement coaxial
Does anyone know where I can get a replacement coaxial cable if this one is damaged? Or details for the specs on the one that comes with it. I know they're sold on digikey but i'm not sure of the specs on the default one in my Fuze to be certain of which to pruchase to replace it.

They are not that easy to damage and can be purchased on eBay, but I think we are not talking about Fuze. From my experience, devices with the same form factor as Fuze would have a flex, rather than a cable similar to HTC Universal (which, incidentally, is the device we are discussing on this forum)
Hello, can somebody help me ?, One day my hd2 fall on the floor and my digitizer crash, after that phone works well i had only few cracks on the sreen, 2 months later my phone fall second time but only from low-altitude on the floor. and my lcd stop work phone only vibrate and boot sound works but the lcd is black.do you think is somethink wrong with lcd or with motherboard ??? thanks a lot
It is the LCD, it has stopped working. Your digitizer may have stopped working too but you have no way of knowing this though as the LCD is not working. You can get a replacemeant digitizer and LCD that are already connected to repaiar it with. Do a search or have a good look through the threads in the back pages here and you will find a good bit of threads on people that have done this and go to Youtube and have a search there as it is some great DIY videos on doing this on there.

Yeah ebay will probably be the best place to get replacement components. And just a tip the Euroupean HD2 and T-Mobile HD2 replacement digitzer and LCD combos will fitt in either version of the HD2. But the T-Mobile ones do not have to me soldered to the main board and the Euroupean ones do have to be soldered. Now I do not know if the connector on the ribbon of the T-Mobile ones will be able to plug in to the Eroupean ones as i do not know if they have the resiprocating connector on the main board of the Eroupean models.
i have european version(non-us) P/N 60H00295-00P with ribbon wich need soldering digitizer so i look on ebay.but still i have care about motherboard:/

Not true!
T-mobile touch is connected to LCD through small connector and European version HD2 touch have to be soldered to LCD, but BOTH versions of 'LCD+touch combo' are connected to M/B through connector, no soldering is needed at all!

You may just be right my friend, it does look as if they both have the connector for the Main board. The combos come with the LCD and the digitizer already together, so yes there is no need for soldering. I was under the impression it was not his way. I will do further checking into this later as I just pulled up like 10 different sites but none show a picture that is conclusive enough for me to say for sure but good catch there pvii.

More of that, cable and connectors have the same size and pin nimber, seems that they are interchangeable (LCM+digitizer assembly of course). Motherboards have the same size and shape too, NAND is the only difference I could observe.
Hello , my volume buttons have stopped working , i have opened it and seen that i need a new flex cable , my hd2 version is tmous 1024mb , on ebay i only have seen T8585 flex cable.
It will be good for my model? because i havent seen different flex for my model anywhere and i think it will be good. Just need to be sure. Sorry for my bad english
i think they use same cables but i'm not sure.just google it
Found nothing on google. Anyone can help with this. i think i will order it , because i cannot found flex for tmous.
Wait! They don't use the same flex cables, the Euro and Tmous versions have different motherboards, cases and flex cables! I work on them ALL THE TIME.

They USE THE SAME flexes!!! I have both Tmo and EU versions, all cables are compatible (bottom buttons, main flex cable, LCM), I've tested all of them. Yes, MoBo of TMo is a little bigger and wont fit in an EU housing, but all connectors are absolutely the same in both phones.
Anyone else please comment, because I need new flex for t-mobile version.
so flex is the same between 2 versions?
Second, anyone have any good tips on how to separate lcd and digitizer without breaking lcd?
because everytime I try to separate lcd from digitizer from touch pro2 they break!!
is the hd2 the same? glue together?

OMG! He doesn't believe me!
These cables have the same contacts and more of that, the same P/N: 50H10116-01M.
I changed one broken in T-mobile model with one from EU HD2 version and it works as needed, camera, BT, WIFI, all as with the original cable.
Other alternative is to solder broken connections if you have eagle eyes

Did you heated LCM to 60*C before separating them? And YES, in EU version digitizer and LCD also are sticked together with double-sided scotch-like adhesive which looses most of it's stickiness at 60-63*C and digitizer may be separated with thin plastic sheet, I use a half of credit card (they can be very easily separated in two thin sheets).

The connectors are the same but there are two different part numbers. I always replace with the correct one so I suppose maybe they are the same size. However many times there can be small changes involved the people are not aware of. A manufacturer I deal with on these has 2 different numbers and has strict writing of which one to use with which phone. So for me, it wasn't worth using a Euro flex on a Tmous HD2 when they are similar in price.
Can you give me a link where to buy usa hd2 flex cable?

You did not understand, I did not checked only connectors, I've installed in a TMo HD2 main flex from European version, works perfect, just as the original one. If You want, you can replace only "correct one" but I wrote in my post for those who can buy main flex only for EU version because of shipping limitations or for about 20$ less in price (I didn't found main flex for TMo less than 64$ and for EU version price is 42-43$).
Just for knowledge, It can be repaired if you are able to handle an soldering iron with micro-tip and have a 20x magnifying glass. It will loose it's shining look, of course, but who will see it without opening the phone
How fragile is the Flex cable for the bottom buttons? I've got a HD2 with a broken digitizer that I replaced but the bottom buttons don't work anymore and neither do the lights on it, it was working before I took it apart and I have been careful with it. Same thing happened on another HD2 I tried to fix.
Also the ribbon cable for the LCD screen is very hard to connect again because of the tight angle it bends and goes in and the tab on the connector that locks the cable doesnt seem to lock it properly and the colur looks slightly faded unless I put pressure on it which makes it work normally.
Any ideas?
the connector is pretty fragile and there is a high wire density on that small flex cable tip. I were in your situation yesterday, managed to get the buttons working after some 8 tries at reconnecting that flex cable to the motherboard. Try to insert it as deep as you can get it and try to secure it tightly.
The display connector is fairly easy to connect, i make my connections while keeping the display tilted at about 90 degrees from the mainboard.
Don't worry about that, it isn't the baddest situation you can get (try doing the same thing on a htc herald or some older querty keyboard eten's .. that's a real hell)
ontopic.. ah yes, the flex cables are 100% compatible, one of my tmous hd2's has an eu flex cable. It's working just fine. Electronically speaking.. they contain 100% same components.

Right.
LCD screens are different bu you can change them only if you change as an assembly of digitizer-lcd.
housing, chasis and mother boards are different, the rest can be exchanged.
So i've read through the stickies and havnt come across anything really substantial, tho I have seen a few other user posts about their G2 suddenly losing video.
That's the issue I'm having.
Here's a little history for you:
Customer brought this phone in to me, said it had water damage. Bought it off them to tinker with myself. I opened it up, and sure enough there were some water stains on the flex cable and the back of the LCD. I replaced both with brand new parts, and now the phone boots, but has only a black screen. It receives calls, touchscreen works, makes clicking noises, all that jazz.... just no video
I've pulled all the rf shields off the logic board to take a peek under them, and there is no water damage at all on any part of the logic board that I can see. LCD and flex cable (and midframe) are all brand new, and I'd really like to get it working!
Somehow I dont think HTC will be willing to warranty this for me (tho I have replaced everything that had water damage, so it should be undetectable as there weren't any water stickers in the phone for some reason)
Thanks in advance!
well, after taking a long google walk, I decided to contact the manufacturer of the LCD I bought and try having them replace it for me. hopefully that is the issue and not one of the chips on the main board or some other cable i missed.
If it IS a chip on the board, I'd love for someone to point it out for me so I can try a reflow. Dont wanna reflow the whole board cus it's still got the internal stickers and I dont wanna damage them in case I can finagle a warranty replacement out of HTC
so does anyone have any other ideas what may be behind this issue other than the LCD? I dont want to have to wait to send this LCD back and get a new one, especially if the LCD isnt the problem
I'm not 100% sure about HTC phones as I have not opened one up yet, so i'll speak with my experience with BB phones instead.
When I was in the process of replacing the LCD screen of a BB Storm, there were 2 different types of LCD screen for one device. Perhaps this could be the case? In the BB case, there was a part number followed by either a 001 or 002, neither of which were compatible with each other. My assumption is a driver issue with the main board.
It's a small and simple thing to overlook, especially if you have prior experience in doing things like this, but I thought it would be worth noting. I would compare the old damaged part with the replacement part and make sure the part numbers match up. If the replacement LCD is from China or Hong Kong, I would be weary about their quality.
Regards.
well I got it on ebay, but it was a California seller. as far as I've been able to determine from looking at listings, the LCD's for HTC Desire Z and G2 are identical. All the clips match up right, and all the ribbon cables looked identical to the one I pulled. I'll look into checking on this a little more in-depth tho so thanks for the info!
Hey Bro,
did you managed to fix your phone? I just changed LCD twice, but still the same it boots and all but no video on it... You can even call it, answer everything else works but the screen... Im thinking to change the FLEX RIBBON CABLE, but after reading your thread not sure if thats going to fix my problem. With my original screen I had no backlight on the LCD with the replacement I got backlight on the LCD again...
Any suggestions, ideas welcome!
So my screen stopped working a few days ago. It went black slowly, from the edges towards the center.
I took it to a repair shop and after they've tried a few screens I have came to a conclusion that some other hardware is faulty, as the current screen is 1000% fine. (Digitizer is functional, and the backlight works because the panel is OT dark when viewed in a dark room.)
I think my flex cable is faulty. What do you think? In this state the phone's not worth more than 100 euros so i don't feel like throwing it away, a flex cable cant be more than 50 euros?
So let me know what do you think

If they tried a few other screens. Then I doubt it is the cable as the new screens would be using a different cable. IT very well could be the connector on the board. I would send it to LG to be sure.

The new screens have a flex cable that is a part of them. Check out the attached picture. The part circled in red is the connector on the "board" (or is there another board inside the phone?) i think is faulty.
EDIT: I've made a mistake, its not the one i circled, the lcd connector port is not next to the charging port. it must be on the left upper side if i recall from youtube videos

Yes that connects the a main board in the phone. I know the new screens have a flex cable but you never said if the screens worked or not.

I'm 1000% sure all screens are functional including the one on the phone right now, because:
When I bought the phone, the original screen was half dead (two vertical lines from top to bottom), so the seller put a new screen. However, it wasn't glued well and it was lifting a bit on the sides.
I went and got a brand new screen, used the phone for 2 days when it went completely black. The brand new screen went black. So i went to the store because i had warranty, and they've put the OLD (the not glued well) screen and it was black as well. And the other ones were black too. I think you see the logic here. It's definitely the connector on that board. Why else would ALL screens be black?

Agreed it seems to be the main board that is having the issue and at tha point you maybe better off buying a new phone as it will be cheaper to replace the g2 then getting a new board.

I dont think it is the board on the screen. Something is wrong with the board on the device that is messing up screens attached to it.

Im gonna go to a repair shop and ask them to put on the board i posted. If it doesn't fix then it's the main board you are refering to. In that case im selling the phone since the main board is like 100 dollars or more
