Yes, that's fine.
Thanks, John. Yes I agree - and I had this in mind to do today. But before I can I must get this wretched USB Camera working so I can see to probe the pins. Sorry about the IC30 pin number - I had corrected it to pin7 but neglected to obliterate the original. Need more powerful explosives, obviously. What I did was to put the NEG probe on pin8 and the POS probe on pin6 - that ensured I was getting the correct reading. When I can view all the relevant pins for:IC30 (OK) IC21, IC22, U8, IC29, IC28A & IC28B, and IC801 - which IC801 I might just be able to do without the USB Camera, then we'll see "what's what". Wretched camera - works on 'VLC media player' but is fuzzy and the pins are indistinct - doesn't work on 'OBS Studio' which has much better resolution. I wonder if there's another programme I could download . . . Michael Studio1 UK 10:55BST 20-06-2018
Thanks, John. That's a good notion! I shall have to work a way round the Endoscope not working - or get it working. It seems I need to get the Endoscope 'into' the programme 'OBS Studio' - then all will function correctly - and I'll see again! Who knows - that may happen today!

Interesting point, John. I was at one time very suspicious of these coils. However it is both VAUXL & VAUXR which are suddenly playing coy. There must be a common factor. Based on our findings so far the strange reason behind the intermittent loss of power seems to be an 'open' between those two GND points on Page114 - CN115 pins1-2 and CP14 pins 18-19. How this happened I cannot fathom, but inserting a Jumper on the FOIL_SIDE of the HDMI_B'D cleared that up. Did it, however, create a new problem? I must now check the power to IC801 again through which both VAUXL&R go on their way to IC801. This is the only dynamic component between CX4 pin6-8 on the HDMI_B'D and IC30. The Power is lost to IC801 pin30 and to IC30 is fluctuating around 4.7V. Michael Studio1 UK 21:07BST 21-06-2018
I interpret this to mean Audio VAUXL is arriving at CX4 pin 8 but you can not pick it up anywhere else, including the other end at CN2 pin 5.
When its "Reset", I believe your presets are lost and need to be reprogrammed. So you probably need to walk through the set-up procedure.
Thanks for looking into this, John, this is a quandary! Since it's so late here I'll have to look into this over the week-end. Re-programmed, you say. I tried Page 19, Mode 10 - but that is a confusing Mode - for it is exactly the same as Mode 11 and the message on the screen said: Remote? Though I do have the remote, there was nothing I could do with it. Maybe the Remote needs setting up as well. My purpose for trying Mode 10 was this is the Diagnostic Mode which confirms Audio Paths (troubleshooting) and I thought it might tell me something useful. I don't know what goes on in IC801 between pin 83 (VAUXR) and pin 55 (A/D_R) and the same with pin 84 and 54 - but assume the signal is processed in some way, for it is lower in volume when it leaves IC801 en route to IC30 - or would be if it worked.

Thank you, Dries. If I press any button on the remote an "M" shows in its screen - so the batteries are OK (I assume?) As for using my mobile - I wonder how that works? I am intrigued! Michael
Than you, John, I haven't actually had a need to even try the remote up to now. I'll reassemble the 'stack' in the AVR and 'give it a go'. I removed the HDMI_B'D in order to physically measure the IC801 to get a nozzle for the 858D soldering station ready to replace it. I'm hoping, of course, this will not be necessary!
