Well I found this site only a couple of weeks ago and am very happy that I did.
Well My VR-507 problem only started about last year and I have had the receiver for probably about 10 years.
Just wanted to say thanks to the person who solved this mystery and say thanks to all the people on the site as well for having the information here on how to fix the problem. I had a feeling that is was the IR Sensor in the receiver that was the problem, but I didn't/don't use it enough to warrant my opening it up to fix it at the time, but since finding this site and thread, I gave it a go and fixed it.
Now it is working like a charm!!!!
For my fix I added a bit of solder as I know that over time from heatup and cooling down that it does affect solder joints.
My theory for my situation is that over time of the heating up and cooling down caused the solder joints to expand and contract hence the cracks in the joints.
