I'll second that. Pictures of the soldering are necessary in order to find out the exact reason why you're this problem.
cant post pics just yet as my cam is sh*t and i aint got hold of my m8s yet, been doing long shifts at work, i do however now have a multimeter!!

ive never used a mulit b4, but ive fiddled with it abit.

now ive tested the jtag qsb
first of all the bridge - i get no current when switch is in middle, but i do when the switch is at the end (0.11)

testing the red and yellow wire - i get a current from the pads to the pins in white connector (0.11 on both) - but when i connect wires and test from pads to end of wire i get a quick reading then nothing

connected up av, getting e79, so my soldering isnt as good as i thawt it was lol, will get hold of multimeter tomoz and report back. ps once ive got freeboot up and running, will i be able to use hdmi then???
cheers
I recall Azeem saying E79 will show even using HDMI cable but this is the 2nd case I come across where someone experienced E79 and had to use A/V cable to see the message!!! Hmmmm

Test from the alternative points, flip the board over and place the probes on the alternative points for the connections. If you get reading/beeping from red point below QSB and the red wire end then that's fine. Same need to be done for the yellow wire and the end @ the ROL. (note that if you are only getting reading, there might be resistance and very high which to some extend means the connection isn't good, resistance has to be ZERO).

You will get no continutiy when switch in the middle because that's the off position :eek:.

oh my, i thawt the bottom position was off lol, im not even getting a proper reading at the end of the wires atm it flashes up for a split second (160.0) then goes off, iz this normal at the end of the wires?

Sorry, you were right I was wrong. The bottom one is off. It's got OFF written next to it, just checked one of the QSB I got. Anyways, if no reading then there's no contact/connection.

QSB ... Here's an example, see where the red wire comes out of the QSB and to that point where you soldered it to? Ideally test the point beneath the board where relates to that red wire where it is coming out from the QSB and the other point where you soldered the red wire to, also from beneath the board. You are basically testing if the red wire has made the connection it meant to do.
