RGH Falcon will not glitch

[DanTechMods]

I did an RGH for a customer on a falcon board. It was glitching perfectly. Would boot in under 10sec everytime. The customer came to pick it up and when he got home and plugged it in it would not boot or glitch. The green center light on the RF board was lit but no green circle of lights and the coolrunners green light no longer flashed.

He brought it back to me and I checked it over and the solder was fine, no pulled pads or anything. So I flashed the origional dash and then 45 sec it shows rrod (0022).

The customer had a previous xbox he tried to RGH himself and bridged some solder so I cleaned it up for him and got it to boot again. I then did the RGH and sent it home with him. He called me a few days later saying it was freezing up and the screen would go black. I flashed that one back to stock and it would still freeze and then it rrod (0022).

These are the only 2 out of close to 100 RGH's i've done that have ever failed.

I will post some pics after work of the current one and the soldering. But would like to get some other views on it. I think its something he either does or the power supply he is using (sameone used on both xboxes).

Bear in mind that Falcon consoles use a 175w PSU, if he used one that wasn't rated for his console then either something was damaged on the board or the PSU was damaged in some way.

Which model was the "previous" console he attempted to glitch?

The freezing for the second box is probably the cpu_rst wire, try using some double shielded wire on it and keep it clear of the coils behind the cpu. check this thread out http://team-xecuter.com/forums/showthread.php?t=75787

the first one not glitching is almost always a _pll_bypass or a standby_clk issue, failing that. if you have not tried, put a 68nf cap from pll_bypass to ground if you have a coolrunner rev A.

Power supply wouldn't have caused the problem.
203w or 175w power supplies will work fine on a falcon and not do any damage.

A 150w jasper power supply wont physically fit into the console and wont power it properly anyway.

0022 can either be a Proper red light fault needing a reflow or a reball.
Or it can also be caused be damage to the area around the CPU_PLL_BYPASS point on the bottom of the board.

EDIT- Thinking about it I'd nearly definatly say its a GPU problem but I cant say for certain untill I see the soldering

I will post some pics tonight. The solder I can say is fine. I have neen soldering electronics for 20 years and these small points are easy compared to some of the stuff I do at work.

Also I checked continuity on the points with Alt points just to be sure and they are all good.

It was still freezing after I removed the CR and flashed a new retail image back to it. The only constant is his power supply.

Its nothing to do with the soldering i'd say.
If you removed the coolrunners and there still throwing errors its a red light (GPU) type problem and it needs reflowing or reballing.

The power supply will not cause these problems.

Hmm i have Done 2 Falcons and 1 booted perfectly under 5 seconds, the other sometimes wouldn't boot and the PSU i was using (had to unplug and plug back in after 3 or so boots)

Yes its been noted that turning the coolrunner off completely between boots does help boot times and consistency at times.
An Alternate 3.3v point that turns on and off with the console has been found but it was deemed not to be stable enough.

This won't have anything to do with one console freezing and the other giving a 0022 error when the coolrunners were removed.

I think you should look into the history of those consoles and where they are kept ie if there played shoved in a cabinet etc.

The consoles my have been on the verge of going out and disturbing them by taking them out of the case just took them over the edge.
Or they may have been towel tricked into working.

Don't rule out a CPU reflow!

 

[DanTechMods]

I was going to try a reflow of the cpu and gpu on both of the boxes just to be sure. It's just stange how when I have them they work great and the as soon as this customer gets them they screw up somehow. Also why is it no other customers are coming back with the same errors. I'm close to a 100 RGH's, I will count the customers when I get home (Kept in an excel file).

Are you sure the guy wasn't screwing around inside it.
Happened to me one time,
I jtagged a console for a guy a while back and I got a call 4 days later saying hes just after turning it on for the first time since he got it back and its giving a rrod error.
And he was blaming me

I knew it wasnt my fault and I wasnt backing down,
eventually when he agreed to pay for a repair I got the console back with scrapes around the x clamp area that had cut threw traces :facepalm: and spring washers that had ripped into the board :facepalm:

he tried to do a preventative x clamp replacement

Of course he maintained he had done absolutely nothing to the board and any damage was done by me:rolleyes2:

Since them I even put warranty stickers on my mods,
and turn on every console in front of customers so they see its working
