Re: Onkyo TX-NR616 won't stay powered on
Unit has been returned to me. Has not been tested with speakers but the speaker icons light up where they didn't before.
Looking through the vent I can see the hdmi board has been replaced, not repaired.Comment

Good news.
Switch over the fan plug, to the empty one, to run constantly.Comment

Re: Onkyo TX-NR616 won't stay powered on
Yes.
You may have to force it slightly, but it will work. I have it this way on the 616 and 626.Comment

Re: Onkyo TX-NR616 won't stay powered on
I'm trying to repair a 609, with no sound issue as well.
I have replaced the DSP, with a D version one and I still have at DSP Netthe ???????
It seems like communication, (or most likely lack of it) between ICs could also be the problem.
I have got a new nand flash, found a bin file firmware and flashed it, but there is still no change.
I don't have audio, USB and network. USB and network are grayed out.

Re: Onkyo TX-NR616 won't stay powered on
What are the power rails i need to check for DSP, Also i found DSP debug mode in Service manual, it will help me to isolate the no sound problem?Comment
-
Re: Onkyo TX-NR616 won't stay powered on
I have never tested the rails.
I have just assumed, that it needs reheating the DSP with an airgun(bad solder job), or it is bad the DSP itself and needs the newer version. Which is, the D version. If you have version C or B, they can be the problem as well. They were recalled, by Texas Instruments.Comment

Re: Onkyo TX-NR616 won't stay powered on
The new one, should look like this: 830K013DZKB4
Do you see the D in it? Yours, is probably B or C version.Comment

Re: Onkyo TX-NR616 won't stay powered on
Here in US, Onkyo will repair this issue for free.
Maybe, you should check with Onkyo, in India.
Mine it was repaired once, so it is not entitled for another free repair.
I'm also suspecting, firmware issue. Maybe, the firmware upgrade was stopped suddenly, without finishing the process, or installed wrong firmware.Comment

Hello,
Purchased a broken Samsung UN39EH5003FXZA (Version CD01) to have fun fixing. When I first acquired it, I did not connect any video signals and only plugged it into the wall. The unit booted and showed the “no signal” window and I could navigate all menus and change sources. I unplugged it, connected my over-the-air antenna to the coax, powered it on, got the unit to scan the HDTV channels, and I think then the TV self-shutdown with the melody. When I powered back up (melody), it would show the channel selected on the OSD and after a couple of seconds, it self-shutdown... -
Hi folks,
I'm new to this forum. So my trusty 17-year-old LG 47" LCD recently died. As I was booting it up, I heard a hum followed by a loud bang, sounds of pieces flying around, and loss of power to the unit. Inspecting the PSU, I saw two obvious problems: a blown thermistor (bang + flung pieces) and a visibly bulging main cap. Inspecting as many components as I could with my Fluke MM, I diagnosed that the following components on the "hot side" of the board were also bad: one of the 2 main MOSFETs, main 8A fuse, small cap (25V 47uF) connected to main caps, and a blown... -
I gotten a Carver CM-1090 amplifier from a friend who has kept it in storage for decades. Opened it up, thick layer of dust cumulated everywhere. Vacuumed it semi-cleaned, and blown off as much as possible the remaining dust. This is a 220V version.
On initial powered up with nothing connected - it works with all the lights and button indicator lit up as pressed, etc. I then powered off, connected a CD player into the CD RCA input and powered it on. It seemed to work for a short while and when I turned the volume up and down to see the the VUs works, the power started to clicked off... -
HP Modelnumber: 14-dh0061nb
This laptop had a shorted cap on a Vcore section. After replacement is works again. But there is still a battery issue.
The battery is HT03XL and with the built-in component test from HP, in the Power section, I get an error: Logic State: Calibration required (20), Charge state: Blown Fuse (42)
I have another same battery, also with error: Logic State: Very Weak (70), Charge state: Blown Fuse (42)
And a third battery TF03XL (looks identical) with error: Logic State: OK (0), Charge state: Blown Fuse (42)
All these 3 batteries are charging... -
Hey everyone,
I'm a novice trying to repair my laptop. The LCD screen has an image, but no LED backlight for the image. It also produces an image when connected to an external monitor.
I have found what I believe to be a blown inductor labeled "L4502" and "120 Ohm" in the schematics (zoomed in image, blue arrow to blown component). I have included an image of the general area of the mobo and an excerpt from the schematics as well.
I am having trouble selecting a replacement component, which I believe to be a 120 Ohm ferrite bead, from the components...
