The problem with Hifonics Centurion X

All the good days. There is a two-channel amplifier Hifonics Centurion X, it is connected to the subwoofer to bridge two channels. The problem is that the amplifier is switched off periodically, moreover, he does not go to protecting, and as if the control voltage is lost, it does not glow either one LED, but the voltage at the terminals of the amplifier is present. Then he turns on when he wants. When I check the house amplifier works fine, but if the fee is slightly curved, the power is lost.It seems that the bad soldering, but visual inspection did not find places with poor soldering. Can anyone have a schematic diagram of this amplifier? If you want I can take pictures of the board.
 
If this amp has a solder connection on the top and bottom of the board on the lead of any through-hole component, that connection needs to be desoldered completely, the lead scraped and then re-soldered. Even then, it's going to fail again sooner or later. This is a bad design. These points are almost certainly the cause of your intermittent problem.


Yes. That IC but deal with those solder connections first. Repair all of them in the amp if you want it to be reliable.

Perry thank you very much, with the mind and can not be said that there is a bad contact.
As soldering I am sure to tell.

That voltage during operation of the amplifier:
1. - 2,48
2. - 4,57
3. - 1,7
4. - 0,03
5. - 1,48
6. - 3,7
7. - 0
8. - 11,6
9. - 3,35
10. - 3,35
11. - 11,6
12. - 11,6
13. - 4,98
14. - 4,98
15. - 2,44
16. - 2,44





Voltage when the amplifier is not working:
1. - 2,48
2. - 4,56
3. - 0,07
4. - 8,25
5. - 1,48
6. - 3,7
7. - 0
8. - 12,04
9. - 0
10. - 0
11. - 12,04
12. - 12,04
13. - 4,98
14. - 4,98
15. - 2,37
16. - 1,55
