iPhone 4 Baseband chip gets hot - GSM-Forum

Hello Everyone,

Water damage iphone 4, had corrosion on the bottom of components near battery terminal.

The unit turns on but the baseband chips get very hot; do you think some small components got burn out and causing a short?

Thanks for your input

perhaps you only cleaned board, and not re-soldered? picture?

Here is a picture, I can see some components are burnt.

Can you please tell me which one I should replace to make the baseband chip not get hot?

I can't tell you which ones to replace, you will have to check for shorts with multimeter, first re-solder those caps, to give it a chance, If the board has been heated could be that you would need to lift the bb ic and reball, Heating ic's that are glued makes more problems.
