htc raphael switch on and stuck with tricolour
 

Hi,I got a HTC Touch Pro T7272(Raphael 100)and last week while i was pressing down the volume down, the device shut down automatically and since then...when i on it the screen will boot up with tricolour.I tried to re-flash the ROM but it still boot up in the same way.The device do work(start up windows mobile) when I press down the on button+center button+soft reset.But after that the screen will keep blinking up the volume column and when i tried to increase the volume, it automatically decrease it again(still blinking).And I am wondering that any expert here can teach me how to save my T7272??Is there anyway to make it back to normal start up??

PS:Please......help if any expert read this and know how to fix it...
Thanks in advance...:)
