i can see it on the pic of board but no use to me ..tell me what it connects to .?
i am wanting to know whats its job is . i cant find it on the schematics .
sorry, it took me so long because I haven't got it completely out of the case, i had to look against a light to be able to trace at the back of the board from a side
It's way past my bedtime, I'm not seeing right and starting to mess things up. I'm going to bed, tomorrow evening, with time, I'll make a few pics, try to upload them, and explain you what I have here.
Because as I was taking the board appart to solder that link i had a closer look at the board from behind and I saw that it didn't go to gnd, but to a resistor that isn't there, and a few other odd things.
Okay lads, I woke up early to do the homework before i get to work, here are the links to the pictures.
back side overlook
Link part(wire added thinking it had tipped off, and re-disconnected when I saw the next parts)
resistors missing beside cn6
wires to ground from r547
back side closeup, resistors wired to ground(extended to the screw beside JK9)
I also realized the two resistors on the last pic, were split in between them, where they join the green wire. I'll replace those and see, before I re join LK58.
With this done, I will be back at noon
I'm back, and it appears now the peak lights aren't staying on :S I've tried a couple outputs and it aint fine though.
Ok agent, I'll do that after dinner, my turn to cook today, I'll make a little diagram of what links where and also I'll write down all the wee resistors and caps missing, and we'll see from there.
LK58
Resistors: 37,62,223,224,334,335,364,378,397,455,475 and 666
Capacitors: 228,258,261,273 and 317.
And on the other I have this extra:
A link from R547/C313/TR15 to pins 5/6 of CN8.
An other from C315 to gnd, (the screw beside CN8)
Then CN9 pin 2, is sent along a wire through the back of the board to the next board, to a point where it should join R79/R80 to gnd, but the line that goes to gnd is cut off.
On the same CN9 pins 5,6 also go through the back of the board, to c11/c18, the line going to gnd is cut off aswell.
These 3 pins are gnd so they are all shorted together.
4 links at what appears to be return gains,
R258 to R177,
R257 to R183,
R264 to 189,
R265 to R195.
And the last is a wire that goes from the second screw at the top of the top board, trhough a 75ohm resistor to ring in L monitor out and another 75ohm resitor to ring in R monitor output.
That's all I could work out for now. I don't know Who did this and why, I'll try and find out. But it seemed to work fine untill it got wet at a party. Or so I've been told.
i dont have the brain power right now to start working out why someone did all that to it . best guess is grounding problems .
i think its best to narrow it down into sections starting from power supply then input boards .
you need a signal tracer or scope really ..
