Vfdp- ( -32.85 vdc) -5v - ( -4.75 vdc) +5v - ( +4.95 vdc)

If you look at the schematic of the power supply board, again, page 103 in my manual, you will see 2 attaching power supply boards, 1 and 2, at connectors CN14 and CN13. You need to test the outputs of the regulators of those 2 boards, pins 1 and 4 of supply 2 and pins 1 and 4 of supply 1.

(AWZ3052 & AWZ2853) or can I take them at the other side ( cn13 & cn14 )....

OK, not totally sure if where I measured was what you wanted...( I measured at connection end of ribbon @ J14 & J13.)
There were actually 5 pins ....
Power Supply 2
Pin 1 - ( -15.33 )
Pin 4 - ( +14.95 )

Power Supply 1
Pin 1 - ( +11.9 )
Pin 4 - ( +11.95)

You said the direct led is lit. Does the speaker A or B led light up when selected?

Ok, good. We need to find out what is going on with the display.
If you look on the power supply schematic again, in the upper left corner you see the "Trans Terminal Ass'y" board (AWZ2893). On that board you see (2) resistors, R122 and R123, both being 1.0 ohm, I believe. Unplug receiver and test ohm reading of those 2 resistors. They power the display lighting.

Test both sides of both resistors. Should be AC voltage.

I do not know what it should be but we will assume for now that is it. On the power supply board look for connector CN34 and test for DC voltage on all 4 lines. Let me know what you get.

albertto: Hi everyone. This is my first post here, so greetings to everyone. I hope to help and get helped in my diy prjects or other stuff. Thank you in advice!! Nov 2, 2024 12:45:30 GMT -5 *

zerolearner: Hi team members I'm new to the forum. I have denon X2000 firm issue I replaced the new ADSP IC but upload the firmware via USB port I got a error message connection failed 5A. FLAG0 present 0.84V is there any JTAG programmer for update the firmware. Sept 30, 2024 22:36:28 GMT -5

redpill: Would you able to provide more details in regards to your fix. Did you replace faulty unit or fixed yourself? I'm having similar problem and wonder how to approach it. Thanks. Lucas. Sept 8, 2024 1:10:29 GMT -5
