[ICOM] DEAD Icom 706 MK IIG

[John King]

I have a dead Icom MK II G and a very much alive one.
My dead Icom MK II G has been posted here before and I have received suggestions which I have checked out to no avail.
II checked out the dreaded internal short caused by corrosion in the B+ and repaired and insulated the spot that usually gives trouble. The repair did nothing to change the state of death of the 706 MK II G.

Next, I removed and replaced the power connector on the rear panel to two  threaded studs that made excellent contact with the NEW cable and new connector on the new cable applying 12VDC.  to the ICOM 706 MK IIG and the transceiver STILL does not come on !!!!!
The front control panel HAS NO PROBLEM because I have placed it on my great working Icom 706 MK II G and that establishes that the control panel works well.
The stacked boards inside the ICOM  are like a CAN OF WORMS and trouble shooting the loss of B+ in the circuitry of the insides of the Icom are really challenging for a really OLD GUY.
If anyone has ideas based on their experience, I will appreciate your help. I would like to find someone who repairs these radios also. I am stumped, so please help, if you can.
Thanks and 73, John, K5PGW
