Question about Aiwa AV-DV75

1 Answer

Power won't stay on

Ok, here is the problem. Last night there was an electrical storm and our power blew (several times). This morning my stereo receiver is DOA. The led over the power light flickers on and off and, initially, I could get the thing to power on for a few seconds at a time. When it did power on there was a lot of clicking from the relay on the power board. Now it just sits there and flashes the led and occasionally the relays click and the lights flash on and off on the front panel. By placing a screwdriver on the surface of each enclosed relay and using it as an amplifier of sorts I can hear that the relay on the power board, below the fuse, seems to be the one making all the noise. Can anyone advise me as to whether or not they think this really could be fried and if so, can I replace just it or are there other components I need to check? I have several volt/home/component testing meters and access to several o-scopes as well as the original technical docs (schematics) on the unit. If some one could point me in the right direction I figure I ought to be able to fix the thing. TIA! ~daniel

Re: Power won't stay on

Your system has taken a hit of sorts from what you describe. The power supply needs to get a clean bill of health before you tackle the output devices. Let me know how things go up to that point...accordianman

Yamaha RX-V750 wont power up

Check the fuse. You might have had a power surge which blew a fuse. If not, check the fuse for the socket. Reset the fuses for that socket. If it still doesn't work, it sounds like the internal boards got fried, or the power supply got fried. The power supply is replaceable, but we don't know if it is the power supply. To check, connect a voltage meter to the power supply.

Something like this happened to me. I found a new kenwood stereo next to the dumpsters, stickers and all still on it, plugged it in, it worked, shut it off to plug in a speaker, didn't turn back on, months later after leaving it plugged in, turned on, I used it, then shut it off for the night, in the morning the standby light was still on, tried turning it on, but it wouldn't for some reason, unplugged it, then the light wouldn't come on, it was once again sitting on a shelf as a paperweight, one day it randomly came on again, and now it 100% works, and I use it as an amp for my RE audio subwoofer, and its worked great since! The reason this kinda applies to you is because its kinda simmilar what happened to you. Just leave it plugged in, and maybe sometime you will walk by it noticing it works.

This condition, may be produced by defective components (Q506, Q507). you can remove those transistor, replace the fuses, power-on and wait for relays click. if the fuses not blown again, them replace both transistor.

Loud buzzing at the first volume setting

Check all your wires and make sure that none of the wires that are powering any equipment (including extension cords, power bars, and power cables on the unit itself) are running parallel to any of the audio cables going to your speakers or from your inputs to your unit. This could be what's called AC hum, which is caused when the electrical current causes interference that gets picked up by the audio cables and amplified by your system. Just make sure you move the power cords as far away as possible from the audio cables.
