My problem is that I have an Icom 706 MK-II, that won't power up.
When I push the power button I can hear a relay click in the radio,
and a thump in the speaker but that is it. I've checked the fuses
internal and external all are ok. Does anyone have any suggestions
as to a fix this problem?

Thanks in advance and 73's

Check the bottom left rear screw. It's probably loose.

I have fixed the problem!!
The Q45 was burned out.
But when I was trying to put a new one,
I was putting it the wrong way!!!
So to All the owners of IC-706MKII:
If you short the pin1 to ground,
replace the big transistor Q45 located
at the PLL unit. and hop !!the TRX will power up
Thanks to everyone who did his best to help me
