Picked up at a garage sale for 5 bucks. Seller said he could not get it to tune. Needed an antenna. Seems like some of the lights are out. But it seems to work fine. https://youtu.be/KTJk3FH4MRA

Thanks. So what I found is the tune needle lights up but does not move on or off station. Not sure how to fix this or if its something I should let go. The muting works but will kill any station no matter how strong. There is a seller on Ebay that has the light LED replacement kit for the lights. 4) GREEN 8v LED FUSE LAMPS + (1)8V-3MM & (7)8V-4MM LED WIRES = 12 LED LAMPS! for 20 bucks shipped. Not sure if there if that is high or if there is another dealer that I can get them from. Thanks for any help.

FYI, this Japanese gentleman has an extensive set of innards photos of the 7065 on his repair site:

I took the cabinet off and sprayed contact cleaner in all the switches and tuner dial. Let dry and works fine. But still two things do not seem to work. One is the tuner needle does not move when tuning, the other is the muting. I am not sure about the muting, it kills everything when its turned on and the tuner is running. Good radio signal and it kills it like turning it off, but in Turntable it does nothing the turntable plays fine and it does nothing. Can anyone explain this muthing lever? Is it worth fixing if its not working correctly? Is it possible to repair the tuner needle or is it something not worth messing with?

AFA the needle not moving, it sounds like the dial string -which connects the tuner to the pointer- is missing or broken. Restringing a dial when you don't have a diagram can be akin to the Chinese Water Torture...

If the mute function is really not something you'd be using, I'd just leave it off. O/W you'll probably need a print so you can troubleshoot it.

You may be in luck. Go here; https://elektrotanya.com/showresult and enter Sony STR-7065.

I must have not posted it correctly. Not the station indacator needle, that works fine. The Tuner needle that moves a bit to show when you are getting a strong signal. Its in the upper left corner of the unit.

So kinda like an eye tube. Go to the link I showed, and it may have a schematic so you can troubleshoot.

I replaced the lights with LED kit I bought from ebay, but I am having trouble with the stereo light. I put it on it seemed to work, not polarized specific. I tuned in the radio and it came on went off station and it went off. Once I soldered it in it does not work. I tested the wires and one reads 10 volts and the other zero. But when I touch one side of the wire to the pos and the other to the side that reads 0 I get nothing no light. I touch one side of the light to the led and the other to the chaise and it lights up but does not tune in or out with the radio it just stays on.

I am wondering if the stereo light and the tuner needle not moving are of the same issue? What should the reading be on the voltage of the stereo light going in and out of station? And the Tuner needle? Any help to trace it down. Thanks
