My amp is making a humming sound. Even when the volume on the stereo is completely turned all the way down. I was wandering what exactly was creating this problem.

Likelly the TDA7293 chip in the power amp has failed. It shorts to one power rail and drags the power down where it hums... this CAN damage the speaker if left on. Verify the problem and replace the chip. Slight chance there are bad electrolytic filter caps but those are easily spotted.

I have a couple active phobic loud speakers, one is completely out of commission and won't play anything. The other will play sound but only through the tweeter, while the speaker itself does nothing. I...


The tweeter is working but the woofer driver isn't which will change the impedance (ac resistance) of your amplifier output. The other speaker isn't working which will again, change the impedance even more. This could eventually damage the I.C. amps should you apply too much volume to the speakers.
You can turn the volume up to normal listening level and with your finger, slightly press the cone on the woofer in and out a couple of time. Does it engage in sound when you do this? If so, the woofer's coil is damaged and the woofer must be replaced. No sound? Open up the speaker (stereo off) and make sure both wires are fully secured to the woofer. Should they be attached securely, your woofer is probably defective. Should you have a crossover network, you can obtain a good, known working woof and temporarily wire it where the old woofer goes, turn on your stereo (minimal volume) which can verify the network pcb (crossover) is working.

Rewire your stereo cables as such:

Red- positive - battery
Black - ground - chassis
Remote (Yellow) - ignition switch

The "LINE OUT" should go to your SUB-WOOFER.

The while-lined wires paired with the solid colored wires are either your Front LR and/or Rear L/R.

Installing an aftermarket stereo, spliced the wires and have everything connected including the remote wire to the factory amp wire but still no sound.


There is no remote wire on these newer trucks....03 and up....u have to buy the harness....although i didnt....i have an 03 gmc sierra and just pulled the schematic and matched the wires. And there is no programming to do on an aftermarket stereo.....I work for GMC and we cant program aftermarket stereos......if u buy the right harness ...and its over $100 then everything should work just fine.....and this does not disarm ur alarm system either....mine still works fine....hope this helps

Poor sound quality


Hi, I sent an email regarding the issue to OnCorpus (the company who makes ProScan)

This is what I got back:

---------------------------
Thomas,
Follow these steps to correct humming issue:
1. Turn tv on
2. Input mode should be tv
3. Turn volume to zero
4. With remote enter 9 8 7 6
5. A menu will appear on left side
6. Arrow down to backlight and with right arrow key move number from 81 to 83, press menu button twice,
7. Turn up volume and listen if hum is gone.

---------------------------

I can't confirm if this works at this moment since I don't have access to my TV.

Humming


Maybe one of the audio leads does not have a complete earth shield and until the second lead is connected, the lack of a suitable earth shield produces the 50Hz 'hum'.

If you should connect either of the two the centre conductors to your body, YOU will introduce a similar hum due to your body acting as an 'earth' to that signal carrier.

These are frequently common effects and it may be a good idea to turn the volume level down on the amplifier or even turn it and the VCR OFF whilst you make or break these connections.

Good Luck!

There sould be an input level control on the main amp that drives these woofers. Adjust the input so that even iof the stereo is tuned up all the way the amp is limiting the amout af input. Before you do this and turn up the stereo, turn down the amp input control all the way then you can slowly bring it up when you turn up the stereo's volume. Good Luck
