Unit clicks but won't turn on
I had a problem with my av-d67 and found the solution on the av-d57 web site. The led on the front came on but unit would not power up. The site suggested removing the cover and finding a little black box behind the power supply and under the fuse. By pulling the box from the front, it easily came off, and exposed two silver contacts. Slightly bending the left conteact until it made constant contact with the right contact made the unit come and it's been working fine since. Your site was great. I was ready to scrap the unit thinking expensive repairs were in order. Whole repair took less than ten minutes. Hope this helps others with the same problem. Thanks for your help and your web-site.
Its off & it doesnt want to turn on?
I just had the same thing happen with mine. First i blew out the 7 years of collected dust. No change. Checked the fuse. Good. Scrached head. Check.
Out of curiosity i pulled the fuse out, and put a small bolt in its place. Powers on right away now. I dont have to sit and play with it for 10-15 min anymore. So, a new fuse should fix it. I will find out tomorrow.
The displayu screen does not light up brightly
If the fault is only with the DISPLAY then there is no need to be concerned as this is due to low filament voltage or grid volage or a faulty display driver IC.So check with the filament voltage which is about less than 3 Volt AC. Also check for the display grid negative to the IC and display so as to confirm the case.If there is no other issue you might as well not tamper if you are not equipped as a false move can cause heavy damage.
Cant hook it up to the tv and make sound on
There are a couple of things going on here.
First concept: The physical TV is NOT a good source of audio or video. It's there to turn audio and video from other sources into something your senses can enjoy. Many TV's (monitors) don't even have speakers.
You probably want the TV-related audio to play on your Sony. Your best source is to get it where it comes from. That is NOT the TV, more likely cable or satellite. Draw the best multi-channel audio (digital, if available) from it into the compatible input on the Sony.
The cable box will also have video and analog stereo audio. Run the BEST VIDEO (HDMI or component) to the TV's video and the analog stereo RCA Audio Out to the TV's Audio In so you can watch and hear cable without the Sony if you like.
You could also run the TV's analog Audio Out RCA pair into an AUX input of the Sony, but that would limit whatever you hear to stereo and any audio limitations of the TV.
TURNING ON, BUT NO OUTPUT TO SPEAKERS.
Try making sure tape monitor is in off position. Also I assume front speaker button is engaged. Another option is that analog setting needs to be changed to digital if digital output
Cant find remote and subwoofer is off.
I had the same problem, lost the remote during a move. I ended up using a really cheap GE (general electric) universal remote. It's a blue and silver remote that cost $5 at bestbuy. Programming code for Aiwa is 839. Then, pressing the "enter" button on the universal remote brings up the subwoofer menu, and pressing it repeatedly will scroll through the individual volume controls for the other speakers.
As far as I know, there is no way of accessing this menu without a remote. Aiwa dropped the ball on that one.
Sounds like micro-processor is locked up or defective. Try unplugging unit for an hour, then power up. If this is not a fix, have pro-tech check it out.
Can i bypass the protect on my receiver?
Sure!... If you want to set the unit and your speakers on fire!
Recievers/amps have protection circuits to prevent pure DC voltage of the power supply from going unmodulated to your speaker(s) if the output transistors/ICs are shorted.
Volume high but no sound only a very low static sound
Make sure the unit is not swiched to tape monitor. Check to see if all inputs and outputs are wired properly. Unplug unit and let it sit unpowered for a half hour to reset micro-processor which may have locked up. When you power it up again, listen for click of speaker relays. Make sure to turn volume down BEFORE you power up. If none of these work, take unit to pro tech for check up. It just might be a simple fix, cheaper than replacement. Good luck.
Static comes from speakers
I think it's a grounding problem. Actually, it's a necessity for all audio-video equipments to get grounded properly. If you don't have a ground connection in your AC plug, your receiver will collect more and more static electricity. As a matter of fact, it decreases the sound quality that you can get from your equipment. I think that the effect of your reaction (slapping the receiver) isn't coincidental. When you touch any metal surface on your receiver (even while slapping) you condact the static electricity to the ground.
I've had a same sort of problem with my receiver. Especially when I connected my laptop computer to the receiver, I heard an annoying distorted sound from the speakers. I found out that it was ground loop, which occurs when the negative (common) signal of the source coincides with the one of the receiver's. As a solution, I grounded my amp, changed all wires with new and shielded ones, and purchased an AC filter. Then, I got rid of the noise. I have to say that the AC filter (Belkin Pure AV Surge Protector, it also includes an AC signal filter)benefited me the most.
Aiwa Z-L700 cassette player will not work but CD player is fine. Is there a simple solution please?
The complexity of the solution depends on the problem. The drive belt or pinch roller may be worn or have a hardened surface. If the tape doesn't turn at all or only very slowly in any function, verify that the tape drive motor is running and that the belt is turning the pulley(s). If the tape tends to tangle up, check the pinch roller. Sometimes cleaning the roller with a cotton swab dampened with rubbing alcohol will work, but if it's too hardened, you'll need to use rubber conditioner or replace it.
If nothing at all happens when you select the tape function, there may be an electrical problem such as a dirty contact on the function switch or a broken wire in the tape mechanism.
This is far from a comprehensive repair guide; it only covers the most common issues other than broken plastic parts. "Will not work" is too general to provide more than that. Cleaning the pinch roller and its drive pin can be done through an open cassette door; everything else most likely requires taking stuff apart, observing operation and perhaps making voltage measurements.
