Jaime Alonso checks the front LEDs that help us more or less to locate the fault or in which section it is ... greetings
The problem is already solved. The fault was on the main card of the U211 and the bad circuit was the LM339N on the right side Thank you.
Hello friends, Mr. Jaime Alonso, the ideal is that you close the question with the accepted solution so that you do not continue giving your opinion on this issue that has already been solved.
I don't know if you have the option that says Do you know the solution? share it If so, comment on how the problem was solved and press the button for the best accepted solution or if you consider that any of the opinions lead you to the solution, then it will be up to you to do the pertinent thing to clarify the solution of the issue and close.
Greetings from Valledupar Colombia.
Take the opinion you gave as an accepted solution to close this topic, do you see the button for the best solution?
If so, take it to close the question.
Have you focused on looking for damage at the source, have you checked the status of the amplifier's output?
quintero4hsor, it occurred to me to comment that before having the relay problem I checked the output amplifiers properly repaired, the characteristic problem of this amplifier is that due to the corrosion some veins had no continuity, I even changed the left amplifier to the right and still So the relay problem followed me, there is no short in the output everything was reviewed. One channel works perfectly, in the other there is 45V voltage due to the relay problem that is not activated. I will try to get the new relay and I will try. Thanks for your comments.
quintero4hson, probably the relay contacts do not close properly so I will have to definitely change the relay. We are in communication and I will tell you the result.
if in doubt with the relay, exchange it with that of the other channel and leave the doubt
Thank you for your suggestion, the plate where the relay goes is that if it is active it is a bit battered to have as I manage. Tomorrow I remove the relays and do the exchange. Thank you.
I already exchanged the relays and they are both good. I'm out of doubt and now I'm going to look for him on the main card. We are in communication and I will tell you the result.
Finally I found the problem and it was on the main card specifically in the U211, that is, the integrated circuit LM339N, which is the one that gives the signal or stimulates the relay diode. Thank you very much quintero4hson for your tips.
Hello friend, I am glad that you could find the fault and that you have shared the solution.
it will be that the diagram of the Crown 5000VZ amplifier can be the same or similar to the Crown 5002VZ amplifier
Your contribution to this fault would be very good to appear as a solution since the information always helps those who have similar or equal problems.
greetings friend Jaime Alonso
