hi guys, is there a posibility that OMAP-L137 from TI to be the perfect replacement for D830K013BZKB4 from onkyo or d810 from pioneer receivers? they are in the same package (ZKB) with 256 pin. the power pins are the same. in the schematics datasheet of tx-nr509, you can view the pin arangement of this chip on the pcb. this must be similar with other boards in other models. we do not have to confuse D830K013BZKB4 with da830 from TI, da830 is not bga and have just 64 pins... www.ti.com/product/OMAP-L137/toolssoftware#nohm.eu/schematics/Onkyo/TX-NR509%20%20Service%20Manual.pdf i think the only diferences are pins f3 and h4 which apear as not conected in TI datasheet, but conected to ground in tx-nr509 service manual. |

Tjmotter is the expert.
Marius, you are from Romania?

Doamne-ajută la mai bine, sa fii sanatos!  Google translate - God help you better, be healthy! I don't speak english very good. So, few days ago i received a broken tx-nr616 buyed from olx.ro with about 70$. The receiver is starting directly in fm and shuts down imediatly after starting. The power relay is working. The previous owner took the device to a service that concluded that mpd70f3477 would be defective, but i don't think so. I did not have time to check for voltages, because I only work in my free time at work for about 2 hours a day. So thanks in advance for any advice, which will be highly apreciated. |

When an Onkyo shuts down immediately after startup it typically indicates a blown channel. You should check the big transistors to find out which of them has a short. When you find that channel you should expect at least 5-6 blown transistors, 4-5 blown resistors and 1-2 blown capacitors. |

I am not sure this will work but must acknowledge that I haven't tried it. The biggest issue is going to be the software. There seems to be a very tight integration of software between the Main CPU and the DSP. For example, Onkyo has a firmware update for the NR3007 that converts the system from a 300Mhz DSP to a 400Mhz DSP but it also updates the Main CPU firmware. It would be interesting to try but I suspect that even if the architecture and pinout were the same, the system would require a lot of software development to get it to work. |

Hi, thanks for your replays, but i think the service was write, or they broked the main micom processor... First pin of the proc (+3,3v) is shorted to ground. Any solution to this? L.E. I also noted that c7026 100u/16v, is mising... they forgot to put it back...   |

MICOM's have firmware written within them. If you have to change a MICOM, you MUST reprogram it. The only programmer I am aware of that can do this is Renesas E1 programmer. I have one of these but they are no longer available. Your best option would be to purchase a replacement board.
Sorry,
Todd

They might work. Some of them are very expensive. The thing you would want to confirm is "which mode do they use?". There is a low cost Renesas programmer available on eBay (about $50) that works with some MICOM's but not others. The issue is that some of the Onkyo designs utilize the pins differently. The two modes are "SIO" mode and "UART" mode. The inexpensive controllers will only do "UART" communications. I bought the E1 programmer specifically because the "UART" mode didn't work on all of the MICOM's and I needed a programmer that would work in "SIO" mode.

Another quick update for those who are looking to repair an Onkyo receiver. The Onkyo x09 series (example: TX-NR609) and the x1x (example: TX-NR616) both use the TI DSP that goes bad. The part number for this device is: I purchased a newer style HDMI board off eBay that wasn't working. It had the D830K013BZKB4. The "official" replacement that does not suffer from failures is D830K013DZKB4. This part is used in the Onkyo x2x series (example: TX-NR626). As noted above, ALL of these TI BGA's can also suffer from cracked solder balls that cease making contact with the board. This can be fixed as noted in the original post by simply adding some Flux and reheating the chip. Knowing this, I found a bunch of HDMI boards on eBay with the "good" chip and bought them so that I could use the DSP chips. On a hunch, I also bought some of the newer boards for the TX-NR636 that use a higher frequency chip (D830K013DZKB5) and was happy to find that they work properly as a replacement as well. If anyone wants to go this route, you will need to invest about $30 for a "re-ball" kit that includes 0.60mm solder balls, a tool to hold the chip and a pre-cut mask to help align the solder balls with the chip. If anyone wants more info, send me a PM. hi D830K013BZKB4 is can replace with D830K013DZKB5?. D830K013DZKB5 can use on my onkyo tx nr616/? |

Yes, I have used the "5" chip in an NR616 and it appears to work properly.
