 Posted: Tue May 13, 2008 11:14 pm Post subject: GRY=Strum Discussion: Cause and Fix Found! Update! |
 |
|
2023: The images here are long gone, but here is a new one from the same guitar to provide some context since even I was confused when initially coming back to this.
To simplify my teenage ramblings, the idea is to clear out all original solder with whichever desoldering solution you prefer, then carefully resolder to prevent any bridging.
Original post:
New Method using a de-soldering iron:
I did this a while back but never bothered to update this thread, so here goes.
Back in March there was a GH tourney at my school, I volunteered to supply my Xbox and my 2 Les Pauls. Since I knew my main LP was all fine and good, I turned my attention to my second LP (the one that had the problem when I got it and decided to go further than cutting in between the points and to just resolder it.
So these pictures basically show what I did.
Here is the board before:
Solder removed:
Resoldered:
Now I am confident that this LP will NEVER have this issue EVER because of this.
If the simple method doesn't do it for you, I'd recommend you try the resolder method if you have access to/know someone who has/are willing to buy a de-soldering iron.
| Quote: | Update: After a few claiming this didn't work, I tested for the problem by holding GRY and crossing each connection pair.
(This is going by the tiny white print next to each wire)
What makes the guitar strum after holding GRY, it ONLY strums when those frets are held:
R4-R4
C2-C4
So check in between those two pairs for any crossing. (This is on the smaller line of points labeled "NECK")
A picture of where you want to check:

| Quote: | I seem to have fixed this.
In my guitar(at least) the places between these points on the main board (with the D-Pad and Xbox Button) were darker and had solder/junk in between them (for me, the 5 points specifically marked in this picture)
(Thanks to BriGuy for the picture of the board)

So what I did was I took an exacto knife and carefully scratched in between the points to get rid of anything in between. And surprisingly, it worked!
Might as well check every point and scratch iffy areas while you are at it too.
If you do this fix please post your results. |

I'm also gonna take a look at the circuit board of mine when I get home. I can confirm that this is a problem with the main circuit board and not the fret buttons or connections. When constructing "The One" guitar hybrid I bought 2 used broken Les Pauls. One of them had this problem and the other didn't. I tried many combinations of fret buttons, different grounds and leads and was not able to solve this problem, but confirmed that it was the PCB.
If this fix really did work for you and will work for others as well, we all owe you for finding a solution to this alarming and perplexing problem.
Oh and a clearer, in-focus picture would be REALLY helpful too. Maybe try a different camera that has the close-up setting.

A picture in your "the one" thread has a picture of the board
http://i32.tinypic.com/xav02u.jpg
Could I just edit that since that is the only camera I have?
The main point of the picture was to show where you should clean it up, so I don't think it matters what les paul the picture is of.

This topic is regarding a common problem with the Les Paul guitar, nothing with the explorer.
However, as long as this topic is alive, Is there any other concrete evidence that this works? I have the GRY strum problem and I don't want to go into my guitar with out more solid evidence that this works.
Also, a more details/description of what exactly I do would be wonderful, this problem is really starting to get annoying. |

To answer first quote, just open it up. When you find the msb you can fiddle with it until it works. Don't worry about voiding your warrenty, its not like take the guitar back and replace it after use.
And its really hard to "break" your guitar once you open it. Unless you grab the board and go ape shit on it and pretend the board is back stop and call over the harlem globe trotters.
Just take it easy on the board andonly touch the side with the tips of your fingers.
also answers second quoter.
AND DO NOT USE A EXACTO KNIFE! you could scrape off precious metals and kill the connector. use something softer.
Say you have some finernails. use those. Or use steel wool. very very carefully use steel wool. THey also have these little plastic scrapers that they use on paint. buy them at your local arts and crafts store for like a buck. unless your canadian then its a looney |

If this works, I WILL LOVE YOU FOR ALL ETERNITY. I've been stuck with my Xplorer due to this problem since December, and due to lack of funds, I've been without a great controller. (My Xplorer has wire issues, I'm buying another one after I buy the proper LP screwdriver)
I WILL post my results in a day or so. |

| This doesn't work. I'm going to attempt hard-wiring with some spare cable, and if that doesn't resolve it, I'm burning this LP and buying two Xplorers. |

The only evidence I have is my word which is that it worked for on my extra LP from eBay.
I recreated the problem on my main LP when attempting to hardwire with the connectors still attached, I must have crossed something and it made it happen.
The best advice I can give is to check around that main board for any crossing/etc.
I don't know anyone personally who has the problem so I can't see if it works.
I'll open that same LP soon and see if I can get it to screw up again by crossing the frets.
EDIT: Updated OP with results.

sorry to post for the third time in a row. but i get antsy. i clean the board with contact cleaner and me and my dad thought it work but we realized that we didnt have a problem when i up strumed only down strummed. so can someone who had and fixed the problem look at the circuit board by the strum bar, becasue that is where we think the problem is
