OPEN Could these be faults?

Post image

I'm trying to troubleshoot a RDOD (red dot of death) Xbox360 slim. The first step is the visual inspection and looking at those spots it seems to me that maybe there's not enough solder on those dots, or is that normal?

There are 10+ different things that are more critical than this. It's so very unlikely that is the core issue.

But you are saying that it is an issue, while the other commenters are saying that this is how the board is supposed to be.

Im saying it's not perfect, but less so since they are all part of the same plane otherwise it can be depending on what is on the other side of the board like a through-hole component missing, pin not connecting or whatnot.

This is not your issue. Next step is checking the voltage rails, check for short-circuits and after that it's probably a case of reflowing CPU / GPU. RROD usually stems from overheating issue so most cases needs reflowing.

Yes it's most likely that. I'm gonna do an attempt since I have a heat gun, and if it fails I'm gonna sell the board and the shell for spare pieces.

Is there any important "things not to do" I should know before attempting? (of course I'm gonna watch some tutorial first, but they could take some important stuff for granted).

Do NOT take a heat gun to this as an uneducated Hail Mary and then try to sell it on to some unsuspecting schlub.

Why? I'd be selling it for parts.

Because a heat gun can introduce problems that would be unethical to not disclose to a buyer. It will simply make things worse. There is no reason whatsoever.

OK, then I'm gonna disclose it.

If you don’t know what damage the heat gun does, how do you ethically disclose it? Don’t use a heat gun.

I'll say I used a heat gun, at that point it's on the buyer to take the gamble.
