The board works fine but after five minutes the fan speeds very fast and U5850 get very hot HELP...

 

[2informaticos]

Change U5850...

 

[Soji]

Ok thanks.

 

[Soji]

U5850 not getting hot works fine..
Q3200 now gets very hot have changed it no changed and replaced U3200 no changes

 

[2informaticos]

Q3200 gets hot when you connect charger on different port?

 

[Soji]

no just tested it now...only gets very hot when connected to the first port on the left

 

[2informaticos]

Compare diode mode readings around Q/U3200 with the other ports.

Check the other side too...

Is the "first port on the left" corresponding to Q3200???
Please, STOP using "cardinal" references; don't you have boardview?

Board still working when charger is connected on that port?

 

[Soji]

I want to post a picture of how i placed the board but it says file too large

 

[Soji]

Board still working when charger is connected on the port where Q3200 is located

 

[2informaticos]

Does it get very hot?
There shouldn't be a problem, if it works.

 

[Soji]

It gets very hot and fan speeds very fast

 

[2informaticos]

Interchange it with CD3215 from another port.
Then check which chip overheats again.
