TC 2240

[NSAID]

I have on old TC2240 with an following issue: peak leds on the lower channel never lights over of the second led. Also -20 led is always light up. Channel works otherwise properly and the leds themselves are working as all the led lights up when powering on. Any advises where to start troubleshooting would be greatly appreciated.

Also if you have service manual for 2240 or 1140 it would help alot!
