Surface mount board repair?

<< < (2/3) > >>

yeah no problem and I would have liked to take it on but unless I know I can do it with 100% success for sure I won't take something of a high value like that on.

if it were a $50.00 setup with a 50/50 shot or something I would take the risk but I dont want to risk ruining something of value like that unless I know I can fix it for sure.

northerngames:
are those on the main motherboard or a smaller sister board?

was thinking if it is a smaller board you may be able to get it for less then the 3 chips themselve's.

I have found some tv boards on ebay and amazon that I thought for sure no one would have but sure enough someone was parting the one's I needed at the time so dont toss it out or anything.

drventure:
No, they're on the main pc board. I've done a bit of looking for used parts, but didn't really turn up anything.

It's a dicey repair, but I'm starting to think....well, if I don't repair it, I can either
1) toss it
2) put it up on ebay as a parts box for 10$
3) rip it apart myself and see if there's any little bits in there worth salvaging for something else.

When you think about it that way, it's not like I have much to loose attempting a repair. If it doesn't work, I'm no worse off (other than maybe out 100$ or so).

I just don't know.

zooming in on the troubled spot is there damage to the trace on the third pin from the top of the right side where you have it in red?

the pic looks like that trace is beatup a little when zoomed in.

if it is you could attach a wire from that pin and jump it to another ground point like that via hole that the other end of the trace runs into next.

also to the right of the chip on the 2nd fuse down it looks like there is a white spot in the center of the brown center take a look at that close and see if it is melted at all or perhaps take a multimeter and check it or perhaps all 5 on that side.

if the pin is not connected good it could work but cause it to overheat becuase it is making contact but not actually connected like a cold solder joint or a cracked soldered joint.

as an example its kinda like the original's xbox power supply they would work even with the cracked points but some got hot and burned up or caught things on fire becuase the solder joint's got cracked where the plug went into the psu motherboard and people wiggling the cord.

happens on laptops and many other things even the psone console's had the same problem when it come's to the power cord ports.

drventure:
I didn't notice that, but now that you point it out, I do see it. I'll check that out.

I'll also give that jumper wire idea a try. I'm thinking it might very well be that I still have a joint that's not completely connected.

Thanks!

I'll post what I find out. Working on surface mount stuff like this is completely a first for me  :). Regular ol' breadboards? No problem, but this stuff? My eyes are getting too old for this  ;)
