Question about Alpine MRV-T707 Car Audio Amplifier

1 Answer

LED Light green but no sound.

I had prior problems with my ampflier blowing fuses and after replacing the fuses, which again blew, I finally went into my sub-box and found what I think was one of my speaker wires loose and grounding out (?). Now after fixing the speaker wire problem I get no output sound but the LED light still comes on green. What can I do? Thanks in advance. Mary

LG 42PC!R Plasma TV turns on and then green led blinking with no ppicture and sound !


Your problem is most likely a fried circuit board. I always connect my good electronic to a back up battery. but your problem might have been storm or surge related, I would take it to a repair center and get an estimate.

Why did two fuses blow making check engine light came back on


Scan for codes there a reason the fuses blew, just replacing them isn't always the answer. If they blow again you've got a wiring issue.

1998 Chevy Silverado 1500 Brake light fuse blew, replaced, fuse blew again, replaced relay and fuses. both under hood and in side fuse panel. Fuses keep blowing on turn signal and brake lights. Checked...


you obviously have a short to ground on one of the wires to the back (if it was the front the brake shouldn't blow the fuse). the most common problem is usually in a trailer light harness. if you look under the drivers side rear of the truck, down under the tail light there will be a plugin junction. pull this plug-in apart and see if the fuse still blows. if it does then the problem is forward of that connector, if it doesn't then the problem is behind that plugin. be sure to check for "green death" (electrical corrosion) at all joints especially any trailer hook ups.

It is likely that the O/P transistors have blown, especially if the fuse keeps blowing and the O/L led comes on. It's a repair shop jobbie

Just blew a fuse (15amp) on the aux circuit (clock, saloon light and radio). Went to replace fuse and it blew again. I went through a fairly deep puddle of water at some speed and this has been the result.


If you can, pull the bulbs for the saloon lights and disconnect the radio. Put in another fuse. If it doesn't blow, the problem is in the lights or the radio. If it does blow, the problem is in the clock or some other item on the aux circuit. you may have to wait until the water dries out of the wire bundle or connector where it is shorting things out.

I was boiling an egg in my oven unluckily it blast and light went off.Since then i can not start my oven.No indoor light no power light.


Hi
It sounds like the internal fuse blew.
If possible, check the fuse:
  • First disconnect the power lead from the wall ( Safety first )
  • If blown, replace the fuse with one of the SAME rating.
If it blows again, you know there is a more serious problem, and it should be checked by a qualified person.

No LED light on PSB Alpha Subzero-i and keeps blowing fuses.


Others have had similar problems with the amp on this model. There is probably a circuit design error which causes some components to blow and as far as I've read, fixing it (or replacing the fuse) won't make the problem go away for long. Try contacting PSB or the retailer.
