old mtx mta 250 high current problem

[caseking]

First off , I got the amp with a modified speaker out/remote turn on plug.I know I got the remote turn on figured out becuase it turns on and plays through left channel fine.So after trying all combinations of the possible speaker outputs I think that the right side must not be working(even though the clip indicator led's will both light up).Does anybody here have a close up photo of the speaker outs directly from the pcb?If so, can someone give me the polarities and the bridged sum output locations?Also, if indeed the preamp section is getting the signal and the speaker outs are correct, can someone help me solve why there is no output on the right channel?

This taken from the OEM label on the bottom of my MTA 2x50. If looking at the top of the amp from left to right ther are 5 leads.

2-channel
1= left pos, green
2= left neg, grn/blk
3= right neg, grey/blk
4= right pos, grey
5= remote turn-on, blue

Bridged
right neg, grey/blk= speaker neg.
left pos, green= speaker positive.

There may be a bad connection between the contacts on the board connector and the wire connector. Try pushing up/down on the connector with speakers connected to see if the audio will play through on the dead channel.
