Yes, I think if it is possible you should try as you said to "connect the cap + to the L8010 inductor (if this is even possible) instead of pin 3 on Q8005 that I have now using the wire" and remove the black jumper.
The one thing I don't see is whether you checked continuity from + C8084 to the trace solder connections (see green arrows). There seem to be two. One is the diagonal strip of solder coming down from where the board is marked C8084 and the other is next to where the board is marked C8017. Or am I missing something and you already checked that?
I can't see whether the + C8084 lead is isolated from the circuitry beneath your jumper wire connection. Are you sure it isn't touching C8108 or R10?
I hope the attached schematic section helps.
You about ready to buy a new HDMI card?
Using the Q8002 Q8003 Schematic I have worked out what has broken on C8084 (see red dot on attached Q8002 Q8003 Continuity Testing doc), so basically it looks like the chips Q8002 and Q8003 were not connected to the rest of the circuit.
I have done a repair to recreate the + 8084 Pad, to do this I have tinned three small wires and laid them down individually on each of the three copper tracks coming into the old pad, then joined them all and attached the + leg of the cap (see attached photorealistic diagram I have done in MS paint).
Its not pretty but seems very solid and continuity tests well from the leg of the cap and all of the components that should be attached.
This has given me limited success because all of the analogue parts of the amp seem to be working normaly (none of this worked before the repair) so it seems that C8084 and the associated chips Q8002 and Q8003 are part of the analogue bit of the PCB.
Do you know if the two holes next to the printed C of C8084 are connected to anything because to me they look to be isolated and I was worried that they may cause some kind of short.
My current symptoms are
\tThe amp menu now works normaly on every input.
\tWhen you change the volume or input it displays the volume or input name on the screen.
\tIf I connect an analogue device (camcorder) to the Aux composite at the front, I get full picture and sound with no issues.
\tWhen you switch between the HDMI devices you get a blue screen with the device name in the corner.
\tThere is no picture or sound from any of the HDMI inputs and the amp screen does not show an HDMI input is detected with the exception on HDMI 1 (DVD).
\tHDMI 1 (DVD) is acting differently to the other HDMI inputs because when you connect a device to this port you get a black screen, the HDMI will flash on the amp screen for about 12 secs then stay on solid and show the sound input correctly (i.e. PCM or DD) but you cannot hear it.
My conclusion from this its that the repair on C8084 is now working ok and this has basically fixed the analogue section of the HDMI PCB, but something else is holding it back the HDMI functionality, the only section that I have not looked at the schematic for, is repair I did on C8609 but it seems to be fine, any ideas?
I will also need check the three white connectors on the right that interface as mentioned in your last post because I have now taken the PCB in and out about 5 or 6 times and these may have worked loose.
With regards replacing the PCB for a new one, I would love to do that but availability of the part is an issue because I am based in the UK and there is none available that I can find in the UK and the only ones I have seen for sale are in the US and the cost of importing one from the US is an issue.
