Hi,

I've just soldered my replacment chip to the board but when taking off the broken chip the solder point for "C" came off the motherboard.

Is there an alternate place for the "C" point on the motherboard ?

Is there a way of fixing the solder point back to the motherboard/

An help provided greatly appreciated.

Many thanks,

Does this make the problem any clearer ?

Can anyone advise?

Thanks,

First of all you were probably using a 30 watt iron or held the iron too long which caused the problem. Second, the only way your gonna get it working with the chip is to follow the trace from the point you burned off to the controller chip below and solder a wire to that leg.

Thanks for the reply.

I used a 25w iron and guess I did hold it on for too long when trying to remove the solder.

What watt iron should I have used?

As 3 legs are not present on chip (7, 8 and 9 from bottom) if I follow the trace from the point I burned off can I solder onto the silver part that is flat to the board?

thanks,

From the picture it also it looks to me like it has the 3 legs cut. You will need to rebuild these legs for it to work.
EDIT: Just noticed that you have posted and are aware of this fact.

try using the correct 30awg wire as well. Your wire is way too big .

Ok, apparantly you didn't read enough before attempting this mod. First of all, you can't do anything without reattaching the legs of the chip. You will need to gradually grind the top of the chip until those pins are exposed then either remove the wires you soldered to the board and attach them to the exposed pins or use some wire to reattach the pins to the legs on the board. Now, since you already distroyed one point, you will HAVE to solder that wire to the corresponding exposed pin.

You shouldn't be using anything higher than a 15watt iron, 25 is WAY too hot for this. Also, you should be using 30awg wire as stated above.
