front buttons and white screen problems - 8525, TyTN, MDA Vario II, JasJam General

Hi guys and gals
I have a stock standard Hermes JasJam with standard OEM software.
Sometimes the screen goes white and all the time none of the front facia buttons function.
I can stop the white screen by very gently dropping the unit face down on my desk about an inch and then the screen is normal however the buttons still do not work
Theorys?
Kind regards
John

How is your Universal holding up?

I've been using my Exec for little over a month now, no scratch on the casing nor screen, but I just noticed the tampo print on the side camera and backlight buttons are rubbing off.. No biggie but I'm a bit anal about these stuffs. How is your Universal holding up so far?
As far as the front camera (the one for video calls) is concerned it is okay because my screen protector came with two small round pieces to cover this camera as well as the lense of the main camera.
Yes the print on the backlight button is almost gone after about 1 months of usage. I also find that some marks (about 10 at the moment) developing on the screen side of the cover. This I believe are being formed as the top of the keys rub against the screen side of the cover when it is closed. Rest of the finish I find is pretty good till now with no abnormal wear of the pait work or anything else.
Kind Regards
why the backlight button? what does it do? i have had 3 of these things now and none of them have ever done anything when i press the backlight button.
just curious

I think all it does is turn the monitor light back on if it's off.. same thing as if you just tab on the screen

You have 3 Universals! WOW!
If I am not mistaken, he probably remapped the backlight button to lauch an application. Here is how:

yeah, one jasjar with vodafone - rip off data charges and they just wouldn't let me sign up for decently priced data chunks, and it had a dodgy screen, and 2 mda pro's - the first kept crashing so got sent a proper new replacement which is good so far.
keyboard marks on jasjar
hi everybody. i want to use my jas jar with the screen side outwards.. what happens is that i notice the keys of the keyboard tubbing against the metal portion of the cover (the outside) when i turn the screen outwards. will they cause marks on the surface.?
Keys are made of rubber like material so it is very unlikely that it will cause scratch marks. I have a Piel Frama case which has a film like material covering the keys. Thats the best solution if scratching the device is your main fear
hi
using mine in laptop mode ever since i got it in mid oct, no scartches on screen and none of the buttons lost markings and except for two marks on side of screen because of the two elevated rubber protectors, no other scatch or mark any where else on the body.
I dont use any screen portector or any case but always make sure that i dont have anything else in my pocket except Exec like keys etc
hi .. sadly there are no o2 exec or imate jasjar cases availabe here in india. if anybody knows please let me know .. thanks
You can purchase them online from Piel Frama or Brando or PDAir or Proporta....
The pivot worked loose, but there a thread on how to fix it.
Going to try later this week.
bougt it in october, not really been using it but every thing is still ok. It needs resetting very 2 days coz it crashes. it cashes mainly in contacts list and other time during the change over from landscape to portrait.
never had a pda before.
does this happen much to others?

SOS - Hermes works fine just that there is NO screen!

Really need help here,
My hermes suddenly decided that visuals are no longer needed.
That means the screens stays off all the time (yes even in bootloader mode).
It works, receive calls and flashes roms but in no situation can I see anything on the screen (pitch black screen).
I've got no warranty so I took it apart and checked each cable and connector - no issues were seen. I tried changing SPL-s, RUU, Roms all worked but left my tytn with that black screen.
Did anyone see this happen or has any advice?
This sucks big time :-(
No one? Oh man, I guess it's dead then :-(
Last bump before giving up and throwing it away - please?
send it to me if your gonna throw it away : - 0
I've given up on mine as well. It has white screen though. Where do I dump this thing?
If it is out of warrenty, I would take it apart as is sounds like the hardware, check the connections to the LCD. Does the backlight still work, or if you put it in strong sunlight, can you see the LCD working?
My Hermes had a white screen also. I found that if I squeeze the bottom right hand corner whilst resetting it would sometimes work. It seems there is a chip on the switch board that needs the right ammount of pressure on it. I think it was a design flaw as the herm200 and 300 are different. If applying pressure works and you are confident enough take the hermes apart and put a couple of small pieces of plastic or paper between the front buttons and the small square chip on the switch board. This worked for me.
The service guide is available if you google. Let me know if you need more info.
As for the black screen that sounds more serious sorry not seen that one.
what are you guys willing to sell your pdas for? Mine fell in a puddle and i need one for parts. The white screen might be fixable the first couple of times but then it dies off for good, the black screen i've never heard of.
So if you want to sell for a reasonably cheap price let me know, i can buy a new keypad online for $50. So around there would be nice!

I just tested this on mine and actually got some results.
mines the opposite though, it will NOT work with any pressure. I left all the screws loose for that board under the buttons, and left the LCD assemble screws out on that end and it works, But if I press the keys it whites out again and won't come back until I repeat the dis-assemble/re-assemble
I had a similar problem but this was after someone dropped mine on the floor. The screen would just be white screen, while everything worked. If I pressed the bottom right of the phone it would sometimes come on and stay on for a little while but would eventually always go to white screen.
I did manage to use the phone but had use a program called Net Control which allowed me to control the phone over WIFI with the phone screen shown on the PC. Got the phone replaced in the end by the people who dropped it.
i got the flex cable and my phone still has the white screen problem....wtf///

White screen all the time. What should I buy?

Hello,
for first I've already read some topic covering the white screen problem. I have the white screen every time on my Hermes since booted. Going into bootloader also shows white screen. I don't see any signs of misalignment.
I've already taken apart my Hermes and reconnected all connectors I've seen, including D-Pad connector, tightening and loosening the screws by it. I see there's nothing else I can fix without replacing any parts (or am I wrong?) What should I buy? Do you think that the actual screen may be faulty? Or maybe the flex is damaged and I should buy it? (well I think that some chip is connected to flex so I don't know if it can be replaced anyway). My main question is: if the screen is all white, is it possible that the actual screen be faulty?
It could be a number of things which could amount to $$$$ by throwing parts at the phone - may be cheaper to just buy another. Before the completely all white screen did you have occasional white screens with increasing frequency? First try some of the fixes for correcting whitescreens - pressure on the dpad - etc. If you still get nothing the chip could have come loose - but who knows?!!!! Need some more information - history etc.
Unfortunately don't know the history... bought cheap off ebay hoping it can be easily fixed already ordered the screen, if no luck, will send as spares/repair in my country - should earn something anyway.
i have a fault with mine some times (well a lot now) when i open it or close it all the way i get a funny fuzzing on the screen and some times it just ends up going black, move it back and forth a bit and the screen collour is inverted. i have to press the power button twice once for off then back on and it stays normal collours till u move the screen again. is this called white screen?
Not really - yours should be an easy fix. Seems like the flex cable is either loose or cracked slightly. It only occurs when you slide the keyboard out right? Any problems with the front keypad - with the unit closed?

[Q] Why do i get black screen when calling or being called??

Why do i get black screen when calling or being called??
because of the sensors on the top left of your phone. They detect when your phone is close to something (i.e your ear) and turn off your screen, which is a good thing otherwise you (your ear) would be pressing lots of keys without wanting it.
the problem is I get a black screen and i cant get out of it even if the call ends unless if someone calls me back and I am using android 2.2 on my HD2 .
with wm6.5 there is no problem can you please help with that ??
thanks
have you got a case on the phone thats blocking the top left sensors on the phone???
Have you got a screen protector fitted,
Especially if its the genuine HTC HD2 screen protector (SP P300) with the 2 little holes around the sensors @ the top of phone
After suffering from the same fate just recently & thought initially it was a problem with the new Android ROM i was using,
I was surprised in my case that the screen protector was the culprit, removed screen protector, Absolutely fine now.
I have a screen protector but when I use win 5.6 there no problem with that, the problem start with android 2.2 I used many roms but nothing , I really love to use android its very frustrating
Make a test call by lifting screen protector in the area of the sensors OR by removing screen protector
I think it work for me,I will try it for few hours and post the results.
thank you very
Glad to hear I may of helped you,
Removing my screen protector solved my problem which was identical to yours, My phone has now been fine for several days.
Out of curiosity was you using the genuine HTC HD2 screen protector (SP P300)
I am now without a screen protector for now, But I like to protect the screen from scratches etc
I have recently purchased a Vikuiti DQC160 screen protector which does not have the 2 holes around the sensors
Once I receive it & fit it I will let you know if my phone suffers from the "BSOD" (black screen of death)
Maybe the Vikuiti DQC160 will be a better alternative screen protector for us HTC HD2 Android users.
thank you again for your help...
I did cut a littel piece of my screen protector where is the sensor located.and I think it work fine,sometimes it goes black but not like before I mean its better now.I searched about the protector that you bought but its expensive here in America,I will just stick with mine... by the way where did u found ur build??? it works fine for you ??
thank you

Dasaita PX6 7" - touchscreen partially working

Hello,
i have Dasaita PX6 7" without hardware buttons and some time ago the touchscreen started to do strange things like i'm driving and i hear the media makes *bop* sound as if i've touched the power touch-button and the screen goes off or it launches a program as if i've touched the screen over where it's icon is.
Now it seems it stopped doing all this but a portion of the screen is just not working, not responding to touch.
The pic of the unit is from the web but mine is the same. I did the color rectangular areas tho to show and say - the green area is responding to touch, the red area is not responding
I write for over a week to Dasaita on Aliexpress where i bought the unit for solution or for new screen - they just read, no answer. I also write to their FB page - no answer.
Because the portion of screen which is not active i can't drag and drop icons from other screens to main screen - i have mouse, but i cant select and drag. Any suggestions?
And please tell me if i can fix this touchscreen (maybe it delaminated somewhere and its not making contact) or where i can get new (because of high chance to ruin this when trying to fix it).
Thank you
Have you ever recalibrated the touch screen?
I donĀ“t know how it works on yours, but for a couple of units it works like all 5 fingers touch at the same time and hold it until you get a marker on the upper left screen.
Touch it as exact as possible and do that for all corners as you get the touch point visible.
For the buttons on the left side you should have a setup in the settings menu.
Hi, i watched videos about the 5 fingers touch but it doesnt activate on mine.
I entered the factory menu /with the 126 password/ where are similar functions and tried them several times just to be sure - no change.
The buttons on the left side are part of the touchscreen even tho they are on the black stripe, its jsut painted, it dosn't matter.
BR
In this case you should get in contact with Dasaita and/or the seller.
May be there is an issue with the controller or firmware.
