Question about Samsung SGH-t629 Cellular Phone

Samsung T629 stuck at splash screen

Have a T-mobile Samsung T629. Normally it goes through two or three splash screens before it loads the normal menus. The first is a white background that says Samsung, and has the website. The other is the Tmobile splash screen.

Anyway, when I turn on the phone, it goes to the first splash screen where it says Samsung, but doesn't load anything beyond that. The screen is effectively frozen. Holding down the power button does nothing, and I have to pull the battery to turn the thing off.

No physical damage, no water damage.

I first noticed this after I turned off my phone, because it started displaying some weird things. The background had gotten messed up, with different colored blocks in the corners of the screen. When I turned it back on, I got this problem, which has been persisting ever since.
---------------
Another note that may or may not have relevance: When the phone is off, and I plug in the charger, the keys light up, but the screen remains off. Normally it would turn on, and the screen would show an image of a battery charging.

    Hmmm, thanks for your ideas. I might see if I can get the phone reflashed, since as far as I can tell, the hardware is ok. Sadly, the phone is out of warranty.

    As for the other ideas, here's the thing: I can't even get to the point where I can punch in any numbers. This screen is all I see. The phone doesn't turn off when I hold the power button, it doesn't do anything but display this start-up screen.

    If you have any other ideas, that would be awesome, and I really do appreciate your help!

Take your sim car out and try using these codes to reset the phone.
*2767*2878# and *2767*3855#

Your phone software could also be corrupt.
If you go to samsung you may be able to update the firmware in the phone over the internet.

If all else fails have the phone re-flashed by a technician.

dear,
the strip that connects the keypad with the other circuitry is damaged. you need to repair it or replace it...it will be checked by an expert technician of mobile that either it is to be replaced or repaired...

flip and slide mobile have this kind of problem..moreover, it depends upon the usage of phone for flip/slide...
don't use it roughly, next time , it needs a lot of care..

good luck..
