I would go after easy low fruit first and resolder everything that has a heatsink on it (like anything on a heatsink).
Try messing around with different input and output settings to see if there is some setting where the channel actually does work?

There is no DC on the output, because the amp should be in protect mode then.

all right I'll disassemble the unit and proceed to resolder everything that is connected to a heatsink ! thanks you good sir

Av receiver is fixed ! found that the front left channel joint was completely cracked , full disassembly of the back all the audio board side and visual inspection made it ! thanks for the help I'll keep the SM , and if there any real good tilps on saving the DTS IC , i was thinking about installing a fan to keep it cool , maybe combine it wit a heatsink , but if someone have tryed something and has no problem wit it for many yeara working that way , let me know please ( except glueing a heatsink to the IC )

I think that keeping the equalizer on the low side ( -3db ish ) and not cranking it past 75-80% for long run could be a good idea but im no expert in this , and either about those IC knowledge
