    Onkyo TX-SR606

    Hi,

    I am repairing an old Onkyo TX-SR606 with a bad HDMI board. I replaced most of all the caps and the board is back alive. However i don't have an OSD or any output signal on component video. It is caused by an empty video EEPROM Q8085 probably damaged or wiped because of the bad powersupply on the HDMI board.

    I search everywhere but i can't find the firmware file. Does anyone have the Q8085 firmware bin file for this receiver and willing to share?


    Kind regards
    Arnold

      I believe I have this ic around here programmed. It was given me by a member here if memory serves. I do not have the bin but if you are patient I can dump it but it may take some time for me to get to it.

                  The initial problem was a bad right channel causing the amp to go into protect. I repaired the channel and checked out the preamp board for bad caps. After that the sound was fine. Then i found out the HDMI didn't work at all. I checked the DC converters on the HDMI board and there was a lot of noise on the output voltages. I replaced all the 100uF/4V capacitors and later i replaced all the other 220/470 capacitors. After that the HDMI started working again.

                  Then i noticed the OSD didn't work and after some checking also the component / svideo was dead. Now the videocontroller gets its instructions from an eeprom Q8085. I removed it to check if it was bad. I could read the eeprom without a problem but it was empty. My guess is that the bad DC converters were oscilating so badly that it eventualy wiped the eeprom.

                  I found an image of a TX-SR605 and i flashed the eeprom with it. The OSD started working so i know this is the solution. However the OSD menu of the 605 is different as of the 606 so the menus don't match. I just need one working TX-SR606

                  The 606 generates a lot of heat. I measured the driver circuit at 70 degrees celsius at 6Ohm. The HDMI board is on top of that. Most capacitors are 85 deg. versions. Thats just asking for trouble.

                              Bad news. Unfortunately this ic appears to be blank. It gets recognized properly but reads all FF's. I tried a different flash ic and it reads fine. Sorry for the let-down.

                                      I got another 606 to repair with a bad HDMI board. But it still had a working videoprocessor so i could make a copy of the firmware in Q8085

                                      So if you need it see the attachment

                                          Thanks for the firmware debruina. I got the rca video inputs and OSD working again on my SR606. HDMI itself was working ok.The VD displayed ????????? and the Q8085 was indeed blank. I replaced all the 100uF 4V caps too. The sr606 q8085 firmware did not work first time but the sr607 firmware did, although OSD only had three options. I then reflashed your SR606 Q8085 firmware and works perfect. I used a ch341a and had to take chip off with hot air as could not get sop8 clip working.

                                              Would you happen to have the latest firmware for the following Onkyo TX-SR606:
                                              Main / DSP / SR / VID

                                              Thanks for your help.

                                                  Hi,

                                                  I have an Anker SoundCore 2 (A3105) that I saved from the trash (well, I guess there's a reason why it was supposed to go into the trash...). The problem is that it always turns off after a few seconds (sometimes it stays on a bit longer, between 30 and 60 seconds, but it still turns off). The power light turns on and the bluetooth light starts blinking, but both abruptly turn off again. The "turn off sound" is still played after the lights turn off. Sometimes, it also loops the on-off cycle several times without me pressing any buttons. If I connect an AUX cable, music...

                                                  All ports work , USB , Ethernet, Type C ... but HDMI + Display Port don't work

                                                  I searched on reddit and google for problem similar to that, and a LOT of people had fixed this problem by updating the firmware. So i tried , i searched and found 1.1.13 utility and 1.1.20 utility that can help...

                                                  Hi guys.

                                                  I've got a Ubiquiti US-8-150W POE switch which has issues with updating the firmware.
                                                  Turned out to be a bad EEPROM chip. It would read the firmware and work as normal, but failed to write new firmware to it.

                                                  So I took off the chip and read on EEPROM and saved it. Wrote to old chip and failed to write
                                                  Got New chip and writes good.

                                                  THE PROBLEM...
                                                  It fails to fully load the firmware, POE lights fail to work during g firmware test during load. I'm suspecting bad EEPROM Read.

                                                  Does anyone have a Good Firmware I can have?...

                                                  I'm currently repairing an MSI Vector GP66 12UHSO laptop with a motherboard reference MS-15441 ver 1.0. The EC chip (ENE KB9548QF2) on the board appears to be damaged and needs to be reprogrammed.

                                                  Can someone please send me the firmware (EC/Embedded Controller) or indicate where I can download the correct EC firmware version corresponding to this motherboard model?

In particular, I am after the firmware for the monitor. At the end, I have included monitor model information and links to pics and vids of the issue.
