Memperbaiki Equalizer Technics SH-8045 Rusak Tidak Bunyi

My Technics SH-8045 equalizer is broken, but it turns on but doesn't make any sound or isn't working. It does make sound when the bypass is turned on. This type of damage can have various causes, including the bypass switch or the bypass circuit, the power supply, or a damaged IC.
