Hi i recently got Onkyo rx sr607, the problem was it have no sound even in any mode, then i checked the DSP chip, i found that it getting very hot, so i suspect there some internal short inside, I ordered new chip same part number and i replaced yesterday, But sill have no sound , i checked the voltage rail it is in limit as per schematic 1.2 volt and 3.3 volt. but when i am checking the DSP version on Display its showing D: ??/ ????????? like that .. i will appreciate anyone help on this

Re: Onkyo tx sr 607 -New DSP chip installed
I wonder if the DSP chip might have some internal EEPRROM / flash memory, where it has (or should have) some ID and/or configuration data programmed...Khron's Cave - Electronics - Audio - Teardowns - Mods - Repairs - Projects - Music - Rants - Shenanigans -
Re: Onkyo tx sr 607 -New DSP chip installed
DSP Chip itself have internal ROM? .. i saw a NAND flash ic near by itComment

Re: Onkyo tx sr 607 -New DSP chip installed
I can't be sure, but i wouldn't be surprised. Either way, i'm pretty sure (detailed) datasheets can't be found for those custom(?) chips.
That being said, if it has a flash chip nearby, that could be part of the problem too.Khron's Cave - Electronics - Audio - Teardowns - Mods - Repairs - Projects - Music - Rants - ShenanigansComment

Re: Onkyo tx sr 607 -New DSP chip installed
Thanks for the update. I may have the same soldering issue than, with my TX-NR609. Most likely, I haven't done a good soldering job. It was my first DSP IC soldering job.Comment

Re: Onkyo tx sr 607 -New DSP chip installed
i think your DSP is BGA right?.. in TX SR607 not BGA, ok do soldering and and let me know the result,Comment

Re: Onkyo tx sr 607 -New DSP chip installed
SRT1, are there any other BGA chips on your board?
To me, seeing that it works after a few hours of idle time makes me think that there is a thermal issue, like a bad solder connection which expands and makes connection after the PC board warms up.

Hi
I have a very strange issue with the BIOS SPI chip of an ASRock B650M PRO RS motherboard.
The SPI chip is an Winbond 25Q256JWEQ model (1V8).
The motherbaord doas not POST - it lits only CPU and DRAM EZ Debug Leds, and stays that way forever.
The Flashback function of the motherbaord is also not working, despite all instructions followed correctly - I'm 100% sure of this.
I have then desoldered the chip, backupped the contents, and tried to earease the chip in order to program stock image, but the chip is locked by status registers SREG2 (TB) and SREG6... -

Common SPI bios chip programming Questions and Answers
----------------------------------------------------------
Q: I have a bios request,i can`t post my backup as i can`t read from the chip.
A: If you can`t read from it how do you expect to write to it ?.
Q: Why is my bios chip unreadable ?.
A: The programmer is faulty or has a worn or broken zif socket.
The USB cable is frayed,connector pins worn or some other physical damage.
Not enough amperage or voltage to power the programmer properly.

Long story short:
- dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
- gave the computer to his son a couple years later
- son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
- too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
(seems like the story was not that short)
He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8... -
