This happened to me,no matter which way i pressed the d-pad or any other key, it goes off. I just replaced the keypad....it's working normal now.Try to do that,this just happened to me,no rainy days no nothing.I really don't think it's because of the water damage,because my phone was soaked from rain while driving my Virago several times,nothing happened.So like I said,i just replaced my keypad,not expensive and doesn't hurt to try.

I guess mpe means MyPhone Explorer. now you understand i guess. If not, read the sticky thread here in software, firmware and drivers section.

that's right ceaser2008....
by using mpe (MyPhoneExplorer) you can partly determined either it's a hardware or software issues, meaning if your phone can be assessed by mpe (without physically touching the phone keypad) that means your software/firmware is ok, so probably your phone hardware need to be checked ie d-pad/keypad buttons, motherboard, contacts ribbon etc....the common way to get the phone back to working condition if it get wet (not so much wet ) just dry it using a hair-dryer.

btw pal, i'm not a hardware/software technician, it is just a suggestion and please get other opinions too

Thanks mallaccra, and you all,
I think i got it.. yesterday i had a visit to the service center. I showed my phone and they said without a doubt
that its a display problem, meaning i need to replace the display. I did'nt give it, and thought of opening myself.
Came home and opened it (thanks to the disassembly video), found so many dust inside, cleaned it, did a little bit
investigation and closed it. When power on IT GOT BROD. So i flashed it. Again turned on this time DISPLAY was
COMPLETELY GONE...!!!! I thought its my mistake. Pressed a few keys still no way. Pressed the middle soft key,
it started the demo video (as hadn't installed custom pack, it was on the "configuration error message").
I could stop and start the video... and i can hear the sound... but NOTHING ON THE SCREEN..
And hence i concluded that the DISPLAY had completely GONE..!!!!
Now i had ordered a Display from my friends shop to change it..
BTW do you have any suggestion to make on this... if so pls feel free to do so...
Thankyou all..

@bluechip

How can you write your phone is dead, where only display is not working otherwise according to you, your phone starts.

What you need to do is- first on first, flash the phone again with customization.
DO THIS ONLY IF YOU HAVE CONFIDENCE calm down and open very carefully the phone. Look if by mistake you have left something unplugged. But IMPORTANTLY, you need to be cool. Dont get hasty.

I have experience about this matter last time, this happened because the back light suddenly off when there is short circuit between the flex cable and the metal part just below the flex cable. You can try this and is ok after that.


good luck
