Repairing an old DVD player

Thread starter #1

Does this MIP2C4 component look healthy? Why is there a dark spot around it?

As an aside: I've tried finding the datasheet for it to see if I can easily test it, however I can only find Chinese PDFs.

It looks to me like some liquid soaked into the board and has entered the board via the holes for components. You can see it to a lesser extent around other holes in the board.

The board looks fine, although the chip does look to have been getting warm - but that could be normal.

One easy thing to check is the 270K resistor next to it, that 'may' be a start-up resistor, and 270K is in the range that's likely to fail (going high or O/C).

I would also suggest checking for any S/C diodes or high ESR electrolytics.

Only then try changing the chip, if you can source one.
