Isolation transformer modified and installed to isolate all grounds from earth ground. Scope is helping with audio troubleshooting already.

That's right, but the front panel display and the fact that the internet updates all work tells me that at least some of the digital circuits ARE working. And it's all for fun anyway. I don';t really expect to ever get this thing working 100% again, but I have patience and a lot of time on...

i'M Not giving up just yet. most of the power audio stages are still working (7 of 9) and I ordered an RS232 cable to do some service checks with the free"Termite.exe" program. Hopefully, with my oscope and some luck, it will show up the defective area. The unit is about 50% computer and 50%...

Not quite. 7 of the 9 audio amp channels after the preamp stages are still working, and 7 of the 9 pre-out stages are working. Question- will the setup screen on your SR 7011 or equivalent be displayed on the TV IF the internet connection is NOT CONNECTED????

Factory Reset accomplished. No video or audio from normal inputs, But an injected audio signal at the inputs to the 5 chan power amp does work on 7 of the 9 channel speaker outputs and is controllable with the volume knob. Also the corresponding 'preouts' all work fine if the signal is injected...

No audio from the headphones in any mode.

The optical out is only for outputting audio from the TV to the AVR, so it is not needed to get the setup assistant to show up on the TV screen. But thanks for the input.

John, one last thing- had to order an isolation transformer for the troubleshooting steps. This thing has some areas with a "hot chassis" and the service manual is full of warnings, but i can also use it to protect my system down the road as well. The power around here has been squirrley lately.

It finished and returned to normal mode. Will run update again tommorrow and give you the results. But do you think there is any chance that the factory reset will make any difference for the no-video/no audio problerm?

John - Got it running now. "Execute Firmware Factory Restore" Is what they call it. Uses The buttons Dynamic Eq and M-Max to get it started.

John, Got the SR7011 back together today - had to be extra careful, but looks pretty good to me. All the screws are back in ! Whooh! Lots of connectors but most of them are different pin counts so it's hard to really get screwed up or cross connected. Had to remove the front panel assy and...

Update- SR7011 from the dump! So after I got my downloaded Service manual and sorted out the problems with it and the idea that it is a .pdf document and the fact that i did not have a working copy of Adobe reader still on my computer, then the pointers and all the features of AR came back to...

Dear Dave, The Service manual for the SR7011 explains that ARC stands for Audio return channel Dave, the owner's manual says that ARC stands for Audio Return Channel. That is if you are using a TV that is ARC compliant with the HDMI cable setup. I think there are other parameters such as...

So today I found a Service manual for my SR7011 and downloaded it. Looks like the two cables coming up on the right side of the digital /hdmi board are just signal lines from the output stages that have to do with thermal conditions inside the chassis, and they are not carrying "power" to the...

Testing voltages inside now. There are four wiring harnesses visible on top of the HDMI board( which provide all the HDMI video services). Each wiring harness is made up of several discreet insulated wires. There is only one red wire in each harness, and the harness on the left end of the...

Brian, Those sound like great things to try, but i'm fuzzy on where i can find the ip address? Are you referring to the ip address for the TV itself? or the receiver? I think I did see the TV's ip address displayed in the setup screens of the TV menus under "about this TV" or something like...

It might help me a lot and simplify things a lot if I knew what sort of data is being passed by that optical cable between the TV and the SR7011?? I know there is probably digital audio coming down, but is there also Video going back UP? or is it bi-directional for both? Also, what is the...

Dear Dave, Thanks very much for the good ideas. This is a special situation for me. I got this unit for FREE at a place called the "Dufort Mall which is part of the city dump. People bring all kinds of good stuff here that they don't want to just throw in the dumpster. So when i saw this...

All inputs set to default mode, optical cable plugged into SR, TV output set to optical, no headphone sounds present.

Tuner does show stereo is present and stops scanning on a channel.

No Joy- Headphones have no sound out in radio mode

Just spent the better part of two days trying to troubleshoot my "new" (to me) Marantz SR7011 receiver, The main problem is that I don't have any video out of the HDMI output ports,*(monitor 1,2,or3 (at least none are showing up on my LG smart TV) which does display my DVD movies without a...
