Onkyo TX-NR616, constantly clicking, no display, no light/led

Re: Onkyo TX-NR616, constantly clicking, no display, no light/led

You solder a long wire, and install the board, that way you can measure the wire outside.

ok great thanks
i will get on to it

I'm keep saying to you, that you need to solder wires to those joint, where you want to measure.
Look up each IC's schematic, that you want to measure and find the Vcc pin and solder a wire to that.

Hi
I can solder a wire but does the hdmi board need to be connected to test for voltages on the component on the board below

Have you used J-link on these receivers to flash the firmware please

I have never seen this unit AND you have never posted any pictures so I leave that for you to figure out. Based on my limited experience (fixed onkyo 919), you can sometimes get at various areas from the bottom or areas that have test points revealed and then follow those back to points of interest in the schematic.

Does the hdmi board need to be connected

sometimes you can solder "test wires" back to the area of interest that will then allow you to connect your meter while the cards are installed.... careful to ensure nothing shorts (ie. insulated wiring).

Re: Onkyo TX-NR616, constantly clicking, no display, no light/led

an example from the schematics is part 8 (video), there is a q201 (some form of regulator), 5.2v in and shoots out 5 for some of the chip. that's what you need to look for in the hdmi board and the processor board since those are likely not happy and hence are not responding to things (updating, and general runniing). You have checked some of the voltages (as you posted) but those are only at the "entrance" to the card. You need to trace those thru to some of the important component areas to see if they are reaching there.

how would i check voltage as this is on the the board below the hdmi board

ok thanks i will check once i get the board back in the receiver

Those "sounds" are not digital sounds, or need digital processing. So DSP could still be faulty, or have voltage issues. Check the DSP, or HDMI chip for 3.3V.

check where please
where do i check for voltage you are saying
but the firmware updates fine when it gets to the dsp
Many Thanks

Re: Onkyo TX-NR616, constantly clicking, no display, no light/led

look for the 5v things in the hdmi and video processor cards... follow those circuits to sources.

Thank for the reply
I've been checking coils and resistors randomly as the seen to be checking fine in terms of voltage
If you can be more specific and what to test them I can do that. I will appreciate it very much if you can let me know
It seems like the dsp is working as I am getting sound from tunner and vtunner. Sound works from usb and headphones
Plus sound works from rca
The receiver was working fine until one day when nothing would show up on osd but the hdmi passthrough worked but I thought a reset would work so I did that but nothing. I was told I can configure the passthrough from using the buttons on the front of receiver and I have tried that but nothing. Tried selecting hdmi out to main only but nothing

Re: Onkyo TX-NR616, constantly clicking, no display, no light/led

those only indicate a voltage is present. you need to check them further into the board. Further, 5v is used in multiple places and is especially associated with hdmi. It can be "destroyed" readily from hdmi issues such as poor / shorted cabling, power surges, etc. Depending on where it is generated and what other circuitry uses it, it can be a problem. I think it is likely that you have lost the 5v somewhere and thus the resulting chips are not "happy".

Hi
Thanks for the reply
This was working fine and one day the hdmi stopped working
The hdmi passthrough was working
but then i reset it and i could not get the osd to work
if you can tell me where to measure then i will
i will really appreciate all the help please

Re: Onkyo TX-NR616, constantly clicking, no display, no light/led

i have bee checking everything seems to be checking out fine
L8002 - 1.0V
L8004 - 1.4V
L8006 - 1.0V


L8932 - 1.3V
L8942 - 1.8V
L8952 - 3.3V
L8962 - 5.2V

I don't think any of us can help you with these.
I don't have his Email, I have contacted him only via forum.
I have never dealt with flashing anything on Onkyos.

I am sure someone can
I am sure someone has fixred there onkyo

Re: Onkyo TX-NR616, constantly clicking, no display, no light/led

On the board there are several service connectors that seems like are for different things
If I need to enter uart mode to look at the vmpu do i use p8702
please can someone confirm
Thanks

Re: Onkyo TX-NR616, constantly clicking, no display, no light/led

Thanks for the reply
do you have his email that you can pm me please

Do you know if I flash a new firmware to the VSP chip using a programmer will this bring back the firmware for the vmpu

or is it possible to use jtag or uart to flash the firmware for the vmpu
please reply thanks so much

Can anyone help me flashing firmware and using jtag / uart for this receiver
thanks

Re: Onkyo TX-NR616, constantly clicking, no display, no light/led

In my opinion, your best bet is to talk to Tjmotter(on the other forum), but he is not showing up much lately. I believe, that he quit repairing these receivers.
