Further to my posts in 2008 regarding faulty output "Trinity of Worries" I have at last found the possible cause and will show you how I fixed it in my case. The fault lies with the group of grey cables that carry the signal between the output board and the board with the volume control. The connectors are a poor fit and the movement of the cable is working the connectors loose. FIX: Lay the Trinity face down on a blanket towards the right side of a table so the pitch bender is not on the table. Take off the back. Remove the connectors from the pcb that holds the output sockets then remove the board itself. The pcb that lies underneath has two screws visible, loosen off the two nearest the four grey cables.
Find a small piece of rubber approx 4mm thick and the size of a stamp. Drop a small amount of Superglue on it and gently squeeze it inbetween the chassis and the connector.
When you tighten up the screws, this will prevent that end of the connector working loose. Refit the output board. Before you re-connect the connectors, look at the pins on the socket for the four grey cables. This is the culprit. CAREFULLY push the two pins nearest the back of the Trinity, slightly to the left. They are marked (R IN and SEALED). This will improve the connection. CAREFULLY push the connector into ints socket. Using a small piece of gaffer tape, restrain the cables and also the headphone cable to the inside of the chassis. Hope this helps, It worked for me. If you would like images of this fix, please email me at derek@ornate-frames.com ~ Good luck!

Re: YIKES!!!!!!!! SUPERGLUE?
Hi Spacecowboy, I'm the author of the Trinity output fix. Due to old age and inhaling fumes from glue, I cant remember my derekthedalek log in details so had to create this new account. Anyhoo, I appreciate your concern about using the dreaded Superglue and maybe I did'nt word it clearly enough. I suggested applying a drop of Superglue onto the rubber packer, not dropping it into the Trinity. I should have also suggested that wearing a thin rubber glove would be a good safety measure too.
I have uploaded a new video of the fix on YouTube:

Re: DEREK get off this forum please
No need to be so bloody insulting to the guy Spacecowboy.Spacecowboy wrote:a thin rubber glove while using superglule to a piece of rubber to fix a loose connection. YOU HAVE BEEN SNIFFING TOO MUCH GLUE!!!!!!! i just hope i you arent selling any of your work on ebay!!!!!!!!!! the more you say, the dumber i know you are. the best thing you could do is get off this forum.
IF GLUING RUBBER TO APPLY PRESSURE TO A CONNECTOR THAT IS SOLDERED INTO A BOARD MAKES IT WORK, THAT MEANS THERE WAS A SIMPLE SHORT WHICH CAN BE FIXED PROPERLY. THE CONNECTION WILL REMAIN FAULTY, BUT NOW YOU HAVE GLUE AND RUBBER AND DUCTAPE........ somebody tell me to stop, this guy is killing me.
I THINK he is only suggesting a fix to stop the problem re-occuring i.e. to add extra suppoprt and take pressure off the board and connectors. I know from experience that this problem can return even when fixed conventionally with solder!

Dear SpaceCowboy. I posted a reply to your comments on the YouTube video. You need to calm down and get this into perspective. If you know a better way for Trinity players to fix this widely known problem, then post something constructive or shut up. I am too old to be entering into any further school-playground banter, so deal with it.
