DGX strange issue with Corona V1

[luminol]

after more than 20 key grabbing with DGX , i've got the first that drive me crazy , im suspicious on the new jrunner version , that maybe make buggy DGX ECC for corona 16MB , all the solders are perfect i can show you , check them 5 times, with meter , continuty look good , but no green light at all , any idea why ?

another thing with DGX solderd and stock dump , everything run perfect if its matter ...

Nobody has responded to you because you haven't provided pictures of your install, your Jrunner log, or any really relevant details.

Jrunner isnt creating a buggy ecc... Its either A. The soldering, or B. The wire placement/routing.. Pics are needed.

Is dip switch #8 on?

 

[Steel City Mods]

Is dip switch #8 on?

I didnt ask that since he claims to have retrieved 20+ keys with dgx, so obviously he should know enough to set the right switch.. Then again, ive seen it happen enough, that i wouldnt be surprised.

this is the log , like i said with the nand dump and DGX the unit work properly , but with DGX ECC (and also the alternative ) no DEBUG LED at all , im adding pics with JRUNNER log .

hope you will see something i've missed but im feel no .

new update for my problem , i've just got a new CORONA V2 , solder everything green light blinking , so the DGX is just fine , he is not faulty one , what else its could be for the CORONA V1 [email protected]?#@#?#@

another thing , this CORONA V2 show me first time XELL on TV with HDMI , what so unique in this unit ?!? , or its from the new JRUNNER ?

i've never seen CORONA with XELL on tv ... great one with any MOnitor COM

dip 8 isnt on in the pic

 

[luminol]

dip 8 is on for sure , before i've pictured i've tried to play between the mods , nothing changed , trust me its on , tried now again begin the solders again after i did another corona v2 successively , but still the same with two ECC files no green at all , something weird in this one , with DGX boot normally with stock with ECC nothing happen .

what the F##K its could be ???

did u try both versions of the ecc for 16mb?

 

[luminol]

yes both are same results no green at all , what else can i do ?

 

[marsey]

Get a multi meter and test con's
cr3 issue has been eliminated so it comes down to connections and board

 

[Martin C]

I would have thought after 20+ consoles, learning to solder would have been a priority after the first one.

You *are* aware that multi-strand cables need to be fluxed and tinned before soldering, yes?

 

[ppkpatrick]

Could be the angle that the pic was taken at,but it looks like the red and black nand wires are shorted.

 

[jligg]

Did you give the cpu_rst alt point a try yet. Cut cpu_rst short as possible to reach the alt point

The NAND x wires also been removed its just look like shorted , for the quality of solder I can say its look better in the final installation its after so many tests , tried all the 3 points for CPU_RST , still the same , I've got some new piece of knowledge for this one , this client tried before me to do it by himself , he tried to read the NAND with TX sd reader but it's v1 so regular NAND x should be enough , I've read the NAND without any probs and any BB , like i said before the unit power on with dgx & NAND dump , so the NAND is fine , there is any way to measure with meter some points and give you results ?

The DGX is good because I've did today really fast corona v2 key (a unique one that had xell on tv) after that tried again for this pain ass corona v1 but still nothing , what else should I try , I don't have anymore ideas

Thank you

Looks to me the the resistors are missing at the E and F points on the board and you haven't shorted them.

Well spotted!!!

 

[luminol]

What resistors should be bridged for corona v1 , all the bridges should be shorted on v3 & v4 ?

Sound weird to me , any info for that ?

 

[madhaxer]

Make sure it is a V1, it may not be a V1 or could be a V1 that just happened not to have the resistors, but ether way the pads have to be bridged for the dgx to work.
