comfis: Hello, maybe I missed the answer in the previous text . Is it possible to extract the contents of NAND flash for DSP from the firmware update? I have an Onkyo TX-NR535 with defective NAND content

bchoyal: hi mastertech i have also this problem pl May 1, 2021 5:04:41 GMT -5

eddy: *****Need a copy of the Identity/Configuration Rom (Q153) for TX-NR535*****

I have a TX-NR535 which the MCU firmware failed updating. I reprogrammed it via UART0 and the amp powers up now. However, none of the buttons are working even the volume control k Apr 27, 2021 17:56:31 GMT -5

karilla: Hello! I'm sorry to bother you! I'm interested in fixing Error 0-81. can you solve it? Apr 15, 2021 5:24:32 GMT -5

wildone: I don't think the B chip is at fault. The lead-free manufacturing process and solder balls used are more likely the culprit as the BGA still works after reballing Feb 26, 2021 8:06:43 GMT -5

trloki: Hi Todd, Same problem Onkyo TX-NR646, any help on how to fix it plz? Feb 25, 2021 1:35:18 GMT -5 *

btrial: poppabradj I have the same problem with Pioneer VSX-1131, after uprating firmware through NET. Now I cannot access neither NET nor Bluetooth, and also updating through USB doesn't work giving 0-81 error. If you have found any fix let me know. Feb 7, 2021 15:37:42 GMT -5

poppabradj: Hello Everyone, I have a Onkyo TX-NR656 Can model and it's giving me error 0-81 when I try to update from a USB... I think i have corrupt firmware, becasue I had no access to NET, Bluetooth feature. The On screen display never Error 0-81 now.. please Help Jan 7, 2021 21:33:29 GMT -5

gjaky: Hi Craig, Why do you need it? I mean with multi channel amplifiers all channels are the same, it is usualy possible to find at least one working channel so you can identify (or at least guess) component values for repair Nov 16, 2020 2:53:07 GMT -5

craigr: Actually, I have been unable to find schematics or a service manual for the Lexicon LX-7 or LX-5 amps. Of anyone has a copy I would highly apreciate it. Oct 31, 2020 15:28:59 GMT -5

analogrocks: Those are pretty pictures! Set one up running a ps1 or NES and sell them as retro gaming projectors. OR post them to me. Just put the stamps in the corner. Should make it just fine

iwwy1969: Hi all. Nice forum. I have Onkyo TX-NR616 no sound and no usb access. I have 5v at usb. I found that oscillator close to DSP is not working. It has no voltage feed from DSP. During the testing through display DSP shows version D?

lfcfan: Hi Todd, have been reading endlessly about the topic, and I really don't think that I'll be capable to 1. do the job myself as I don't have enough of the right equipment, and it looks like only the people who have access to TI exclusive distribution networ Apr 9, 2020 17:17:06 GMT -5
