xperia X10 can't on,blink,blue light,,99% solution-picture with solution

its not easy to replace ur mentioned cpu. Because it's not available.
But I have 90% confirm idea to recover X10 pda.
cautions:
1. may happened charging problem
2. may happend camera problem (if u are not expert to remove camera)
come to the point for main work:
1. remove backup battery
2. carefully solder CPU and surrounding area.
3. Then make good flash by setool.

I think it will make u happy . tested by me many times. ok ?
