ANSWERED PSU light goes red while dumping nand

[cj_goalie31]

i took all the wires off and still get red light. I have a question regarding the J2D1 solder balls though. On my multimeter i am reading continuity between some of the solder balls but not all of them is that normal or do i have to attempt to un-bridge the conection?

 

[Martin C]

J2D1.6 and J2D1.7 are both GND. You shouldn't need to test them all, just the ones you've soldered to.

 

[cj_goalie31]

i have check all the spots ive soldered to theres no bridging is it possible that i fried something on the board where i was soldering or blown a capacitor?

 

[Martin C]

Did you get readings for all points?

 

[cj_goalie31]

no it just doesn't have any continuity between except for the points you were talking about on the J2D1 they get 0 ohms

 

[Martin C]

Do you understand what I'm asking for?

 

[cj_goalie31]

what type of reading im getting between solder joints???

 

[Martin C]

no - read my nand-x troubleshooting post.

If you don't understand how to use a multimeter, google it.

I believe this is what Martin C is talking about.

 

[cj_goalie31]

kk based on your guide im getting 0.21v on solders 1 2 3 4 and on 5 im getting .25v and 0n 6 im getting 11.20ohms

 

[Martin C]

If you've removed everything from both areas and they look clean, you'd definitely got a short somewhere on the board.

 

[cj_goalie31]

kk thanks would that cause the psu to not let it boot

 

[cj_goalie31]

based on the voltages i gave you do you have any idea where the short could be because i cant find one anywhere but the solder ball on my CPU_LL_BYPASS broke/fell off could that harm the console i know there is an alternate point but could that be the problem?

 

[Martin C]

I would advise you use this board for practice now. Not only do I think you won't find the fault but you won't have the ability to fix it.

If you get another console, I'd get someone to RGH it and practice on this in the meantime.

 

[cj_goalie31]

i have two more xenon boards but you cant RGH those right?

No but they might be JTAGable. That might be worth looking into.

 

[cj_goalie31]

nope they bothe have dashboards higher than NXE

 

[Martin C]

I would have practised on one of the xenon boards rather than damaging an HDMI one....

 

[cj_goalie31]

the xenon boards are still operational though and i use them for online

 

[Martin C]

Operational for now - Xenons have a bad track record!
