COOLRUNNER Trinity RGH stopped working after months of use

[irondoom]

TX Product(s) used:COOLRUNNER REVC
Console Type: TRINITY

Description of problem:

RGH was done ~4months ago, console was working fine since then. Freestyle dash, etc, etc. all working great. Today what happens? I try to turn on console and it just gives me the normal beep, a green light, and then green light goes out few seconds later. And nothing. Sometimes fan and HDD spins up for a hot second while green light is still on, sometimes not. Basically sounds and looks like its gonna boot, but then it just craps out.

I did not move the console, it still sits where it has been sitting under the TV since RGH was completed.

Was the console working before you started: Yes I did not do anything ( it was working with RGH installed for several months).

I took it apart to get these pics of the install for help troubleshooting:

The obvious thing to do here is write the stock NAND back and see what it does.

I'm looking at R3B15 and I don't see a resistor there.

Your console won't power on if that resistor (33 Ohm) isn't present.

Sure enough the goldang resistor is gone!

If I left the flux on could it have made the resistor come lose? I'm trying to figure out how the thing worked for 4 months if there was no resistor there :/

Is there somewhere I can scavenge a 33 ohm resistor to put back on there?

 

[Martin C]

You obviously attempted to solder to it originally. Since you didn't clean up your install, the flux has caused damage to components it's been in contact with (corrosion).

awww shucks that's the problem...I guess that will teach me to clean up my mess after i am done.


so am I screwed now? I just cleaned everything up pretty nicey with some alcohol and that resistor seesm to be the only visible damage. So If I drop another resistor on there I might be good?

I take it doesn't have to be a surface mount resistor? If i can find any 33 ohm resistor it should do the trick?

Lovely sir, I will follow this guide for repairers and update on the progress. Here is a pic of it after I cleaned it up:

Like I said, I did have it working for awhile using alternate point, but the flux + damage from original solder attempt must have been enough to loosen the resistor. Probably it came off all the way when I took it apart again to take the pics.

I hope replacing this resistor will do the trick. It does look to be salvageable if that is the only issue.

Hey dudes I did the repair but still not working

Beeps when I push the button to power up but no boot. This green wire in the pic, it just has a 33ohm resistor between it.

 

[unkn0wn.92]

are you sure its 33ohm resistor ? also did you tried to flip the resistor ?

 

[irondoom]

I am sure it is 33ohm, it was orange orange black gold on the resistor, and I checked it with a multimeter after installed. I did not try to flip the resistor. I can try that but I did not think it mattered.

 

[daretogo]

Time to remove that and fix it where the damage was done then I'd say



Edit: (obviously adding in the resistor)

 

[irondoom]

OK I'll give that a try next! Dang I just see you are in Denver I moved away from around there last year or I could come get pro fixer

 

[hersheys247]

Where u located now?

 

[irondoom]

seattle

 

[irondoom]

Yeah dunno, its reading correct 33 ohm across that bridge, but sometimes it boots and glitches and sometimes it just beeps and doesn't start up. Depends how I shake it, I guess. I am throwing in the towel for the day.

 

[Martin C]

If it sometimes boots, I'd get someone to fix it properly.

I'm not nearly as good as several people that offer their services here. I could fix this (and I would if you were still local) but if you are going to send it off there are better options than me

Intermittent functionality means you are close, but probably have a poor connection somewhere. If you are potentially willing to sacrifice the box as a learning experience then keep going - you could get it. If you are unwilling to sacrifice the box, then get someone to step in. Doesn't even have to be someone with Xbox experience - just SMD soldering/repair experience in general.

Yeah I do admit like doing this kind of stuff and learning about it, and would like to salvage if possible. I prefer to not ruin a console, though. Here's a pic of the bridge w/ my repair in place and the multimeter:
