Hi I have onkyo tx nr609, got as no sound , after successfull replacement dsp chip of onkyo 616 I descided to start on 609 , t Tjmotter help me alot to make it success, now I have a qstion about 830K013DZKB5 ,I know it is higher freequency chip than orginal 830K013BZKB4, but don't know it is compatible with onkyo 609,I buy thes are from Ali , the same part numbe is I installed on 616 and it was success even firware corrupted (I moved firmware chip between 616 and 414)
The "5" version runs at a higher frequency but I have found it to work perfectly as a replacement for the "4" version. I investigated this previously and what I found was that the D830K013BZKB4 uses a 20Mhz crystal. This chip multiplies that by 20 to get to the 400Mhz frequency. Systems like the NR636 that use the D830K013DZKB5 install a 24MHz crystal which increases the net speed of the chip. My current theory is that installing the "5" chip in a system with a 20Mhz crystal simply sets it up to run at (or close to) 400Mhz. I have tested this in an NR616 and it worked perfectly.
After replacing it, nothing happened(no change). I assume, that my soldering job wasn't correct, but I may be wrong also. I don't know, how would I know, if I did a good job or not? This is not a priority for me right now. Receiver is to old, and is not worth almost nothing these days. I'm doing this, to learn on how to solder a BGA IC.
skydronelink: Thank you I advance

jbmeyer13: Wolfy's Marquee isn't working? Did you spill a pint on it and short the MB?

wolfman: Always the same sarkasm Kurt that's why I never checked in until now. I knew you wouldn't give me a cheerful answer so let you hang for a while. Removed the last part you probably are a decent guy Eye to Eye.
