Bold 9780 - Water Damage - Won't turn on

[Hollywood_99]

Please help,

I am sure this could be fixed. I have a bold 9780 and it was put through the washing machine. I cleaned the board and removed all the corrosion that I could see. I then put it in a hydro-sonic with a special circuit board rust remover and I also used distilled water. Should be no more corrosion on this thing.

When I put a battery in, I get nothing. When I plug it into the computer, it registers it for a few seconds. No lights, No LCD, No keyboard lights. The only sign of life I get is when I plug it in and I hear the sound of the computer connecting to it.

What should I look for? Has anybody run into something similar? Please help.

Regards,

Chady

remove all shields, remove all oxide with thinner, put flux on all IC's and rehot 350 degrees. wash again with thinner, dry all pcb with 90 degrees, leave it get cold, try again.

how can one remove the shield without remove components from board?

[Hollywood_99]

What thinner would you recommend? Also, in regards to removing the BB shields I haven't really had any luck. The best way I found to remove the shield was to put solder around the shield, heat it up and then pick it up, but it's very time consuming.

Is there a better way to remove the shield?

removing the shields can be a bit risky though not impossible. those with experience use the heat gun together with flux to heat the shields and when heated enough, they lift it up. i haven't tried this as i'm wary i might permanently damage other nearby components.

what i do is i have a mini rotary tool which i use tactfully to cut the shields from the top (it requires some carefulness though) to access the components embedded under the shields and then i use the cleaning liquids (in my case isopropanol-100% alcohol and an electronic cleaning solvent i purchased in a shop) to clean the components with a brush and sometimes i use an ultrasonic cleaning machine for the cleaning purposes.

hope this helps.

best wishes and seasons greetings.
