Overheating causes screen problems?

[EyeVein]

Hi all.

Lately I'm facing a strange problem with my device.
when I navigate with it in a sunny day,
or talking on the phone while charging,
the devices gets hot and the screen goes down.
I can hear that the device is working and the buttons is working, but the
touchscreen is 'dead'. its all black.

Even a softreset won't fix it, the device goes up without the screen.
To fix it I need to pull out the battery for like 2 minutes untill the device gets cold.

is it hardware problem? Anyone else experienced any of these problems?


Thanks!

try to charge it via USB and not a car charger. Is there any difference now?
IMHO you should replace the device

Hi
I have the same problem than you
I can use my Polaris in my computer with MyMobiler application but the sceen it's always black.

Sometimes when I do a Hard reset and press button left side it's OK but after some days it's comming again.
I think is not a hardware probleme but software problem.

Do you have resolve your probleme ?

the screen getting black is due to the nature of how a display works. i dont know of it actually damages the device, but i strongly believe so.
the working conditions of the device are written down in the manual, if you exceed those they might not replace your unit. this of course sucks, but it *is* written down to not expose the unit to direct sunlight.

I didn't know about the exposing to the sun ...
well, I hope it isn't got damaged badly.
thanks.

As I said, I'm not sure about the damage part, I could be completely wrong. I just think it *could* be...
If it doesnt change and the device gets unusuable all the time, I'd suggest you send it in for a replacement. Maybe you really got a bad unit, who knows.

Edit: I just thought of stuff which is usually written down in manuals and the glovebox problem popped in my mind: devices stored in the glovebox of your car are breaking down because of the sheer heat which builds up when the car is standing in the sun for a long time. All sorts of displays usually break or get completely black until the unit could cool down again... And in the glovebox they werent even exposed to direct sunlight, its just the heat...

hello. I have same problem. But i can't catch situation when it appears. I think, the sun is not an main culprit, because my phone goes down, when i
playing games in the room! may be it's overheating, but cooling doesn't help me.
To fix it, i do several soft resets (sometimes more then 300 :( ). Sometimes one reset helps, sometimes no. I think, it is hardware problem. Also i have problems with my camera (colormess). May be they are connected.

I will try to send it to service.

Hey, i put my device into refrigerator, and screen is working :). I have tried to reanimate it since yesterday. Battery unplugging didn't help.

F*******K!!!

After ten minutes in the room with temperature near 20 C it's black again.

Can be problem with temperature sensor?

Don't put it in the refrigerator without putting it in a plastic bag or something. Moisture can kill it.

[lamerbot]

i put it into plastic pack.

But i think, that I'll kill it myself by throwing in the wall :(

[lamerbot]

Hm, question:
Where does temperature sensor dislocated? In battery or in PDA?

[EyeVein]

Well,
In the lab they told me my Board damaged up.
total-lost :(

[lamerbot]

What kind of damage?

[ayman morsy]

this problem i faced it two times ,one of them when i put it inside my car and the AC was runing (cold) and my screen became black
and the other time it happened in a hot condition (also in my car)

realy this is very strange

and the solution for both to remove the battery for a while
