I think you've answered your own question, circuit power is not going from one side of the DSP chip to the other and that suggests that the DSP's core is at-least partly DOA. You are indeed correct that functional power should be at 3.3V and yes 0.3V does make a difference to the components that rely on a 3.3V feed, however if the DSP is fried you are not going to see normal functionality or be able to diagnose further.

There is a music button on the front panel that allows you to select Jazz Club, Live and concert hall. It cycles between these 3 options and every time it switches, the audio cuts out


Momentary cutout is normal when you switch between DSP modes (Digital Sound Processing). The unit has to crunch the numbers anew each time you change the parameters.

JVC AX-66 Integrated Amplifier seems to be muted?


You need to have a jumper between the 4 standalone jacks on the right side of the column of stereo connectors. A stereo RCA cable would work for this.

Amplification does not work


It sounds like a source slecton issue. Try the following and if that does not help I would start with a simple stereo setup and source and work up from there.

The RV-8 is powered on, but there is no audio.
1. Make sure volume level is audible. Volume level can be
increased with the front-panel volume knob or the remote
control VOL �� and �� buttons.
2. Make sure audio has not been muted. The message “MUTE
ON” or “FULL MUTE ON” will appear in the on-screen and
front-panel displays when audio has been muted. To deactivate
mute, press the Mute button or adjust the volume level.
3. Check the INPUT SETUP menu DIGITAL IN and ANALOG IN
parameters to ensure the appropriate audio connector is assigned
to the selected input.
4. Make sure the RV-8 is receiving an audio signal. To do this,
follow the instructions that begin on page 2-29 to open the
STATUS menu for the current input source. Hint: (Use the "STAT2" Button on the remote.)

HTR-5240 Will not play audio when switching to DSP


Most likely your DSP board is bad, usually a pretty costly repair and sometimes the board is hard to find in stock.

My receiver is experiencing the same issue now. I was thinking it was an amplifier output stage going out. I only took the hood off and measured some typical voltage areas, nothing too in depth while on the living room floor. What was your conclusion? I'd much rather fix mine than buy a new one.

If "Digital" sign blink on front panel, it means DSP do no start properly. If DSP do not start, main UC mute audio. Change IC, AT49LV002-70TC (IC 817 ) at DSP board (Denon P/N: 262 3010 006).

Thumping Subwoofer


Ive seen this problem in alot of audio setups in vehicles but most peeps dont know this is not a good thing and will cause damage to your woofers or amp. 99% of the time it turns out to be as you said that bad boy muting circuit. alot of these curcuits do use separate transitors or diodes as mute switches but most of them are directly from the Microproccessor. Only way to trouble shoot this is with a schematic and a good car stereo tech. Good luck
