Treo 750 display driver problem?

I have a treo 750. Its used and I don't know what the guy before me tried to do with it, but it looks like all he did was install the official WM5 to WM6 update. My problem now (and part of the reason he sold it) is that there seems to be some serious screen corruption. I'm inclined to think there may be a driver issue? I cant even see the bootscreen. All I can see are a couple of vertical and horizontal bars (mostly around the top) with a multicolor spectrum. The rest of the screen is blank. Hard-reset, soft-reset, neither works to fix it. Oddly, if I access the device through MyMobiler and regedit/change to font to something that it hasn't used before (ex. calibri, arial) it seems to bring it back to life... still no boot screen, but the os will work fine. If I put it in standby mode and then try and bring it back on, I'm back to the corrupt screen. At the moment I've turned off the power-idle feature and just let it go to backlight off while leaving the device on all the time, but I cant leave it like that forever. Any thoughts? Am I able to update the display driver or something?
PS. Display works on my PC through MyMobiler with no problem.
Thanks in advance.

having exact same problem
I am having the exact same problem. The only way to avoid the display corruption seems, like you said, to avoid putting the phone in standby mode... but then leaving it like that all day will drain the battery very fast, obviously.
I'm curious as to what the cause is. My phone is out of warranty already. Purchased summer 2007.
rjackets, have you done anything since your post?

Hey i Still have the same problem, did anyone find an answer yet?

Is this what you're seeing? http://commons.wikimedia.org/wiki/File:Bootloader.jpg

no, it's like all the 1st vertical pixels get extended to the right end and the lines keep flashing, i kind find my battery atm but it looks something like this texture, just with pixels:

[Q] Graphic problems with p5100 10.1"

Hi,
I got this weird problem and im not sure is this a hardware problem or not. For example. when using menus with white background, the background goes partly blue. Sometimes the graphic error is only blue lines in some part of the white background.
but when checking one option in same menu the background turns normal or atleast there is some change in the background. So these errors reacts only when changing options. And theyre always in the same position when going the same menu.
Also when using camera. the view is messed up a bit. there is a clear line somewhere in the picture when going dark to bright. With my english its hard to explain especially when i dont have any idea what is causing this problem.
Below are two attachments that explains the problem much clearer than i can write:

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
And before you ask. Yes, it has dropped and i have replaced the glass. But i got it with broken glass so i dont know was it like this before it dropped and the previus owner couldnt tell either.
Any possible solutions?
Thank you in advance!

Sounds like a hardware issue, just for the heck of it I would open it up and check the ribbon cable to the digitizer/screen, it could be loose.
Pp.

Checked it. Same problem. Tried to change brightness level, hard reset, rooting etc with no luck.
Its just so weird that in some situations the screen looks totally normal. only these few situations cause errors in the screen.

Hmmm, there are dialer codes that are used on phones that run a series of tests to check screen performance and output, don't know if this can be done on a tablet, but I would research it.
The only other time I heard of this was on a phone that recovered from falling in a toilet, the phone was dismantled and cleaned and assembled and it worked fine for over a year, the only glitch was an occasional color spasm on the screen similar to what you discribe.
Pp.

Thanks for the tip! Need to look for those codes when i get back home. I removed the logic board and cleaned it with denat. alcohol. No visible damage at least! trying to assembly it back later today. I decided to order a new LCD flex cable. Its the cheapest part to change.

No luck with the codes i found. after cleaning still same graphical problems. Now i can only wait the new flex cable and hope it will fix those errors.
Anyways thanks for replys and suggestions. :good:

Has anyone experience flickering/glitching after updated to 23.4.A.1.232?

At first I thought glitches I saw caused by the app (inbox) itself. Then I keep seeing it happens on other apps as well.
It is like some elements (ie, action bar) of apps flashing or the whole screen flickers. It usually happens only a second or two at most; too quick to make a screenshot of it.
Though, this problem is not happen regularly, it is frequent enough to get noticed.
Here are some apps that I remembered glitches happened, it happens in other apps too but usually very quick and random.
In FX File Explorer, sometimes glitches occur during transition animation between folders.
When adding a new Google account in Settings, the big top blue part of the screen flickers.
In Inbox app, sometimes tips bar just keep flashing for almost 2 seconds when I closed it.
And, in A Better Camera app, this can happen sometime:

}
I'm considering reverting back to 23.4.A.0.546.
Even though the old firmware has stagefright bugs, it's very unlikely that someone would use it on me, and I don't use MMS anyway.

for me both cameras are better in .232
and yeah I have these screen problem
and did you notice that the speakers are noticeably lower in music ?? now they are like Z3+ !!!!

I had some screen tearing when I first installed .232, but none since then.
Speakers seem just as loud as before.

I do have the same problem.
Made myself a prerooted fw using PRF, downgraded, rooted and upgraded using the prerooted firmware i made.
Also made a factory reset. Now i'm getting screen tearing while scrolling, video glitches and stutterings.

I saw that at first but not anymore (maybe I haven't noticed them).
Strange thing is that 232 version should be Stagefright free, however, I've runned a test and I'm still vulnerable to one of the flaws.

U11+ Backlight bleed.

As title says, the backlight started shining through on my U11+.

It happend today, i was on my phone. i put i down to go get something to eat and when i came back the bleed came. it's around the entire screen.
i haven't contacted HTC yet because i wanted to ask you guys and get your opinions first.
i haven't dropped it, i haven't thrown it after somebody. i've been looking after it.
Sorry for the unacceptable quality on the picture, it's taken with my work phone.

That's not good. RMA it if you can.

Did you get yours repaired? My u11 plus just did the same thing today. I am wondering if too much squeezing the edge sense warpped the screen.

It happened to me too: I was watching a film, checked phone and it presented the same symptom, but in always on display. Rebooted and same problem. After a little time (just 10 minutes or down there).
I am using edge function and it is no longer happened .

I think the last time it happened to me was in January.
It's a bit bizzar that it comes and goes like that, I still haven't figured it out what's causing it.
But it doesn't seem to be a problem any more so I'm not worried.

Graphics Corruption Fault

My two month old POCO X3 NFC 128GB appears to be randomly exhibiting a graphics fault. Occasionally upon screen wake up, this sort of graphics corruption occurs (see first image below)
The first two times this happened, the corruption was blue, the one in the image is red, it looks like a low resolution, low colour mode, and the only way to get the screen to go back to normal is to reboot. I have not managed to intentionally cause the error to appear.
Screenshotting while the error is occurring shows a normal screen without the issue.
Has anyone seen anything like this or have any idea what is causing it? This is my first Xiaomi phone after reluctantly switching to them from three previous Huawei mobiles. Very disappointing and annoying to have an intermittent error two months into owning this phone.

I have indian variant, have exactly this issue.
After updating to 12.0.9 once a while display acts like this.
You don't need to reboot simply go in settings/ display/colorscheme and click standard Display will be back to normal, it's a software glitch which came with new update

Thank you for your message, this very interesting to hear as I have not seen anyone else talking about this and I was beginning to wonder if it was a hardware issue as the fault looks very much like graphics chip corruption. The next time this happens I will try your fix without rebooting to see if it helps, thanks again.
