Onkyo TX-RN515 schematic

[Pragmatiko]

Hi all,
i have that AV amplifier completely dead.
Any suggest?

Tks in advance.

Someone have service manual?

Re: Onkyo TX-RN515 schematic

When I have worked on a 616, I have used the 609 schematics as a reference.
See, maybe it works for you too.
The 609 is on elektrotanya.

attached schematic..

the RL901 is not enabled... i have replaced Q9001 but still not run

Do you have 12VST (12V STANDBY) after replacing Q9001 SMPS IC?

Re: Onkyo TX-RN515 schematic

Yes i have 12 volt

Re: Onkyo TX-RN515 schematic

So is Q7016 (PAGE 17) is turned on to bring PIN 1 of connector JL901A LOW to turn on the relay? See the diagram attached on post 4 that I have marked.

Re: Onkyo TX-RN515 schematic

Tomorrow i will check relay. Pin 1 is low... but relay dont close the switch.

Re: Onkyo TX-RN515 schematic

dont mean to be obvious, but did you check the relay coil?

Re: Onkyo TX-RN515 schematic

If pin 1 is low then you should have about 9V (it looks like 9VDC relay coil, NRL-1P10A-DC9)) on the relay coil, as you can see in the SCH, one end of the relay coil is connected to the 12VSTBY through resistor R9015, the other end of the coil is pulled to ground through Q7016.
The relay may be bad.

Re: Onkyo TX-RN515 schematic

Yes i'll check coil...

Strange that also standby led is off.I believed that with the presence of the 12-volt standby LED was illuminated

Re: Onkyo TX-RN515 schematic

If the processor is not running then the LED will not be on or the LED drive circuit is not functioning.
Any one else worked on this unit before you?

Re: Onkyo TX-RN515 schematic

Yes, another technician have modified it from 110v to 220v

Yes, another technician have modified it from 110v to 220v

And it was working fine until now?

Re: Onkyo TX-RN515 schematic

I hope, is not one of those rusted relays again.
It's a seal one, or you can remove the cover?

Re: Onkyo TX-RN515 schematic

This same power relay is used in a lot of Ohkyo models.

Re: Onkyo TX-RN515 schematic

was relay

Re: Onkyo TX-RN515 schematic

always check the obvious first!

[budm]

Re: Onkyo TX-RN515 schematic

So what did you find bad on the relay? bad contact? open coil?

open coil

Re: Onkyo TX-RN515 schematic

Why would that happen?
It's a nice receiver, I'm using it in my living room, but not for long, because I will be replacing it, with the repaired 626 and it will be for sale.
