Yamaha M 70 with meter light issues

[fenacious]

Hi All, I am sure this has been covered, but I can't find a post on this. I have an M70 whose meter lights are out...not the leds that indicate how much power, but the "power graph" is out (all of the lights). Anyone out there have any thoughts or tips? Thanks.

I was gonna post a similar question. The meters in my M-65 work but all of the other lights are out (Power, Class A Operation, etc). I'm hoping that it's just a cold solder joint or something. I haven't even taken the cover off the amp yet. I'm having too much fun listening to it to want to get in there to investigate the problem.

On mine, all the leds light up all the time, can't figure out why...

All the bulbs are prolly burnt out on yours.
