Screen display scrambled fades to white - ideas to fix?

Hi, i have been experiencing a screen display problem.
When i power on the Hermes the screen does not power on.
If i then place the Hermes on a hard surface and press down hard on the long sides at the edge of the screen i can make the backlight and display appears.
However, if i release this pressure the backlight remains on but the display will become scrambled. The scrambled display is variously showing white noise, scan lines, mispositioned graphics, and ultimately fading to white.
Also, if the phone rings the audio is distorted and crackling.
I have dismantled the Hermes as far as removing the housing for the LCD from the rest of the phone. I then opened up this housing and disconnected / reconnected the LCD flex cable that is by the very edge of the housing. Then reassembled phone. No improvement was made, in fact the display issue was made more tempermental!
However the phone stil works as i am using it at the moment as a 3g modem for my laptop.
But it is extremely frustrating / near impossible to use it for any other purpose in this condition!
I am wondering as to what the problem could be and how i might solve it?
I am thinking that the problem must be due to a poor connection / oxidation / dry solder somewhere.
I would appreciate advice as to what i could do to solve this issue myself.
Next steps???
>>> Would there be any use in spraying a little WD40 into cable contacts?
>>> Someone has suggested passing a heat gun over the PCB to bond any solder that may have cracked.... Although i am sure that this is a trick that can work with old PCBs that he plays around with i am not so sure that this would be such a good idea on the flimsy multi layer boards in the Hermes.
Let me know what you think of these ideas...

white screen
Hi..not sure which version of the hermes you have, but this has been a common problem for years. My Cingular 8525 did the same thing. I finally figured out while placing the phone into a desktop charger that it was putting pressure on one lower corner of my phone and it would go white. It got to the point any pressure on it would cause the screen to fade to white. I contacted AT&T tech support about it and even though fone was out of the warranty period(over a year) they sent me a refurb ATT branded 8525 at no charge. I've had that one now close to two years with no problems.

Hi Oleschuldad, thanks for your reply. I have the Hermes100 branded as the "ORaNGE SPV M3100". Yes i have read that the white screen issue is a major blight for the hermes phone. From what i have read It seems that there are numerous causes and the problem can be difficult to trace to a specific component. The problem that my phone has is the opposite to the what you had with your phone. In that i must EXERT PRESSURE on the phone to be able to read the display. The indication is such that i am certain that it must be the result of either loose connection / bad solder / corrosion somewhere.
Think that i will get a can of electrical contact cleaner spray and clean the contacts on the flex cables.
Looks like corrosion is definitely an issue in my phone as there is some green oxide on the round watch type battery that sits on the main board next to the contacts for the main battery.
I will have to strip the phone down again at the weekend.

screen problem after service

i got my HD2 from service and the screen got replaced, now it's a very tiny and almost unnoticeable black dot in the top center, and when i press it i can see some pressure on the screen at the same spot. is there any possibility that there would be a wier or something behind the screen?
And do anyone know of a way to take out the screen and how i could check it out myself?

My advice would be to send it back to whoever replaced the screen and let them see to it..
It sounds like a dead / stuck pixel so they might not do anything about it as they are often a manufacturing defect - some companies allow upto a certain amount of them before replacing the screen.
Also there's not going to be a Wier behind the screen!

Volume Down Key Broken Any Sggestion?

Hello guys, from around 1-2 Mounths my Volume Down Key is broken.. so its not totally broken.
I think from a long use of my Blackstone and alot of flashing that is the reason why Down is broken also its strange that is not totaly broken, you know that when you remove the back cover the volume buttons are really small and they look black like some kind of plastic so exactly the plastic of the down volume key is broken and now im able to see under that black plastic the metal.. so with fingers i can press it so i can flash new ROMs without a problem but didn`t work when the cover is there and the volume down button just can`t do anything.. i think that other users here can have the same problem because in all Blackstone this is the same material used and etc so if anyone have expirience like this or any suggestion how can i fix this will be very cool
thanks in advance

Funny, my blackstone has the exact same physical problem, making the vol down key more difficult to press, the lower half of the internal one that black plastic you mention on mine is broken.
I read in the hints of the blackstone wiki that if your phones under warranty you could try to get the carrier to fix it, but thats not an option for me since I pulled mine completely apart.
I think its best if you can substitute the broken plastic with something maybe, I really haven't bothered for mine since the button still actually works with the case on it just needs a firmer press.
I have repaired plastic damage on pc cases before (broken front door hinges and such), I just used superglue, some of those plastic 5.1/4" or the 3.1/2" ATA clips you get on some cases, and a stanly.
Im sure I could carve out a small piece plastic that would work.
If you really want to go one further, then what I can suggest is taking the two plastic back covers off your phone, and actually repairing the black plastic part on the back cover, my guess is you could use a couple of layers of heat shrink and glue and with enough time and effort achieve a good result, see, the actual volume button PCB hopefully isnt damaged for yours, as it isn't for mine, and if thats the case then its actually just that internal black cover that is a tiny bit broken.

I fix it today and i will explain how if anyone have the same problem to know what to do its very easy for around 1 minute work and now work perfect:
Because of the broken half plastic of the volume down button the problem was that when im with back cover and i press the volume down key didn`t work because the back cover dont button when is pressed cannot press the volume down button that is on the device.. because all is so tinny and this black plastic that is on the button is around 1/10 of the milimeter very very tinny but on the same time this is enought the button to cannot be pressed. So i remove the back cover and from paper tape i cut one litle squere with the size of the button .. but because the paper tape is really really tinny i put 3-4 paper tapes in one they to become more chik then i apply the paper tape exactly on the down button and then put the back cover so now when i press the volume down button work again because this paper tape help the button to be pressed
Very easy fix for 1 minute.. of course better will be if you don`t have problems like this.. but when heppan you know what to do

nice work!
Looking back at the images I took when replacing my touchscreen and lcd, I noticed that the part of plastic that does suffer the damage isn't actually a part of the outer shell casing, but is actually applied in some way over the top of the soldered buttons on the tiny volume PCB (& ribbon), therefore, you could always take off the shell, remove the pcb with tweesers, apply a small it of electrical tape, and put it back together to achieve a more permanent result
I should've done this when i fixed my screen, I might look into fixing it in the above way in the near future as the volume down button doesnt work that well currently.

I did have exactly the same problem with my volume down key....
Because I still was in the period of the guarantee I sent my phone back to HTC repair center I get it back after 2 weeks with a new volume down key (they changed that broken very very thin plastic) and now it works again perfectly!

The question is if you have a Hardware problem like this broken plastic do u need to re flash to stock ROM when you are going to ask for repair? or when you dont have any problem with the device.. because the volume down key have nothing to do with the software etc do u can go to ask for repair with costum rom?

No way you always have to flash the stock rom (and stock spl!!! they check if "olinex" is there in bootloader!) when you send your phone to the repair center... so did I.
Although this broken vol key has nothing to do with the software the repair center has done a complete test of the phone. And this includes flashing the newest stock rom again. Yes, although I have flashed the latest official HTC rom when I send it to repair center they do that again (after they repaired my device)!! So you always get a completely blank phone back from this repair center.
(spoken from the repair center here in germany but I think this is always the same in every country)

I ask because here in Bulgaria i think we do not have official HTC repair center.. so when i buy the device from somewhere they give me 2 years waranty but from them i mean.. if i have troubles i need to go to the places from where i buy the device and they will repair it.. they will not send it to HTC official or anything else..
thats is the reason why i ask you

same here in germany... i get the name/adress for this repair center from my shop where i bought my touch hd. And then I had the choice if I send my touch hd to my shop (and then they send it to this adress) or I send it myself to the repair center.
I think it'll be the same in other countries. HTC has "partners" in every country for such repair/warrenty things. For germany the repair center is called "arvato services solutions GmbH" (so not an official HTC firm I think)

[Q] Incorrect Error Diagnosis at HTC Repair Centre

Hi,
I had the following problem with my HTC Diamond 2 (it might have got wet & it might possibly have had too much pressure on the screen)
Problem:
The mobile boots ok and the normal buttons at the bottom work fine, as do the volume up/down buttons. The display, however, has what looks like the newton rings and when I press the display it detects a 'press' about 1cm to the left of where i pressed. This means I can't use the right hand side of the display and also can't enter my pin.
Error Diagnosis: (from Arvato Services in Germany)
Mainboard is defect. Cost to repair = € 303.17
Is this possible ? If there was a problem with the mainboard then I would expect to see other problems - and at present, I can only see that the touchscreen has a problem.
Please let me know what you think, thanks in advance !
(ps there should be a question mark at the end of the 'title', don't seem to be able to edit though)

Based on your description and from what I've read, it's definitely the digitizer.
It is possible that you have a damaged board, but regardless, your digitizer is bad.
I would attempt to replace this yourrself then see if everything is fine before sending it to repair.

I had the same problem!
The screen was getting worse in alignment over a time frame of a couple of days. If replaced the digitizer and screen and all is back to normal ..... however it seems to work better then ever before.
The only problem left is dust between the digitizer and my screen, but this is my own fault since I didn't glued the screens. I'll re-open in the next few days and use some silicone to close the gaps. Mainly the volume key has an opening to the outside.
Good luck with the replacement!

Strange Marks on screen

so strangely for no reason at all i have these two strange marks on my screen, if i look closely i can see their not on the OLED panel but not on the surface of the outer glass either, its almost as if their between the both. its very odd as i have always looked after my screen. they are a strange silver color when screen is off and they look like dust when screen is on. although they are small i can notice them at all times and hence are very frustrating. does anyone have any ideas what they could be?

If your device still under warranty then just send it to service center to ask them replace a new screen panel.

well normally i would but i have voided the knox warranty so.. yeah
