I’m trying to fix my Yamaha CR620 Receiver. I need to know how to check why the lights are out.I heard that there might be a low voltage fuse to check but I don’t know where it is. Is it possible that they all burned out together???? I also broke the dial cord and need to replace it. I could use some help with this. I live north of Boston and hoping that there is someone that lives nearby that could help me fixing it?? I would appreciate any help that I can get.
Thank You
Tazman

Thank you for your help. I don’t have any test equipment to check it out with. I don’t want to spend the money on new ones just to find out it was something else. Would you take a chance and replace them?
 
Multi meters can be bought for less than $10.
Walmart, Menards, etc

Some fuses are easily found by taking the cover off the unit.
Some units have fuses under the main boards as well. Removing the bottom of the unit is sometimes needed in that case.
 
If any of the fuses are bad. The unit would not work period! In a CR-620 all fuses are topside.Closest to the power transformer.None of which are dedicated to the lamps.

Do I test them by testing each lamp and using both of the wires going to them ? Do I set the meter so it beeps if there’s power going through them?
 
No power. Unplug it from the wall.What make and model of meter did you get?
 
Never use the diode test/Ω's with power applied to the unit.Never!
 
The lights usually burn out after x number of years of dutiful service. No need to test, they're just dead old bulbs. There's replacements, both original and custom (if you'd fancy a different color), for about $10 on eBay that you can just swap in.
