JVC RX-5020VBK Receiver Questions & Answers
My jvc is not working
If you're needing to run it at max volume something else is afoot.
ANY amplifier has specs. Those specs are at a certain output into a certain load yielding a certain amount of distortion. That is not to say it can't push more power. But you can be sure the distortion figure will rise almost vertically as the power spec is exceeded. Eventually the signal will clip and now we're talking about danger to the amp and the speakers. Protection Circuits are designed to detect and intervene in these cases.
Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.
Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.
Check for loose speaker connections at the speaker as a possible root cause for intermittent shutdown.
Jvc rx-5020v dolby digital problem
Also...If your BluRay player only has a optical output for audio you will need to swap the inputs on the JVC rx-5020v. Press the "settings" button repeatedly until "digital in" appears on the display. Now use the "adjust" up and down buttons until DVD is selected as option 2. It will look like something like:
1CD2DVD
Note: this may bugger any other previous setup you have.
No sound out of subwoofer
Connection from receiver subwoofer output jack RCA plug male go into your powered subwoofer low level input with other end of cable, then you need to select Subwoofer YES/NO on the JVC receiver speaker setup menu option, select YES if this is a powered subwoofer you are using, should power up the subwoofer, may have to adjust a test tone balance for multi speaker output also, try trimming up on the subwoofer channel to initiate the signal on if the sub has an auto-on feature.

make sure your audio cables are going from the audio OUT of the dvd player and VCR to the audio IN of the receiver

2) SK B1560 44 P
3) SK D2390 43 Y
can you please send me some details about these devices (semiconductor, diode, integrated circuit, terminal voltage regulator, capacitor, etc.)
thanks in advance!
