I was sitting on my porch just recording music from my ipod when all of the sudden I started hearing this painfully loud static buzzing sound come and go, but now when I touch the back of the unit, or pick the unit up, it buzzes and the channels are now very uneven and the buzzing sound is becoming more and more persistent .. 

Does sound like a bit of switch cleaning is in order. There's a service manual for the 920 about somewhere on the web for free, makes it a lot easier to work out how to get inside the machine

I downloaded the service manual.

What's a 'record bar' Bill?

It usually oxidises over time due to lack of use and because the audio goes across this bar it affects the output.

 My facebook friend, James mentioned that it could also be a grounding issue and to take note of where the antenna leads go if it's not the record bar?!?! I'll figure it out. I just got some deoxit d100i liquid with applicator because the store still does not have the d5 spray. I have been studying the service manual like a hawk and I'm definitely optimistic and putting myself up to fixing the issue. I'm going to start working on it today since I have nothing else scheduled, so wish me luck. 

Removing the PCB's a real pain in the a$$!!!

Good luck with him too

Now I just have to figure out where everything plugs back in at then test it out.

Tested and nothing changed. Still the same problem.

is it interference from your ipod..tv computer etc...curse me i used the word ipod

wish i was there much easier to diagnose.....as for the record bar sometimes it takes buckets of detoxit....also do you have an aux selector on the back for aux tape etc....spray that to.......also it would be nice if you can test it on battries to eliminate any power supply issues....this must be pretty sadning for you as the 920 is such a beautiful box....does it hum etc on the radio

Nope

so the radio works fine correct....did you spray the right end of the record bar 1 end holds the switches etc...the end you need to spray will actually be on the board....there should be a whole in the bar if your lucky.......lots of it and work the bar about 100 times back and forth vigorously....i had the same prob with my crown 970...it took half the can to fix....also check for loose head connections etc

is there an alc knob, record level adjust if so take it off and spray buckets in there working the control....basically spray all moving knobs sliders weather they need it or not

I have liquid, not spray.

the spray i use dries in 15 mins anyway....apart from what we have suggested im not sure...it could be caps but i dont think so as it's working on the radio

madam i have never used anything other than spray so im not sure if your stuff is any good for the job.....just buy some off ebay lass

Sorry, with respect to Reno this is very bad advice indeed.  Only target areas that you know need cleaner spray, use sparingly, use the straw & mop up overspill afterwards.  Loose spray/liquid can be very damaging.

Reno's in the car restoration business, you really don't want to take advice from him

Here's one of his

You could check the wires from the tape head to the board. Sounds like one of them came loose or broke. At least this gives the same symptoms as described.

That's the extremely rare 4 door rally preped Metro 6R4 don't you know 

no, this is serious. I cleaned all connections, nothing changed. All connections to tape head are perfectly in tact. I don't know what else to do. I'll just have to leave it alone and just accept it the way it is... poo.

Trust you agent haha.....well i have started a repair service....it' called...bodge it and legit..hehe....seriously though....never had any probs with spray providing i let it dry as it evaporates in 15 20 mins....Rome wasn't built in a day.....i hope your keeping well chris and it ain't to boring here....things have been very quiet here of late ol chap

Video coming shortly
