    I have pushed the standby switch many times and it did not work. How does one clean the standby switch if there is dust un it.?

  • youdim Oct 05, 2010

    I will try this or tell the Yamaha pepole in Tel Aviv to do it. Although they told that may a microchip has been damaged. The receiver is brand new and in use for 3 months.

Hello,

your amplifier is having a power problem. The power supply board is defective that's why the amplifier won't come out of stand by mode. Its receiving power but it cannot transfer the current to the necessary part of the amplifier because a capacitor, diode, etc may have been faulty. Until these bad components are replaced, the amplifier might not come out of stand by mode.

If you know about electronic repairers, I would suggest that you open the amplifier and read the power board/panel with a meter, detect the bad component and replace it.

If you don't know about Electronics repairers, take the amplifier to the nearest repairman to fix the fault for you.

I wish you good luck.

Does the standby button work to turn the receiver into standby mode? And just isn't turning it back on?

    It sounds like that the standby switch is not working. Sometimes you can push the switch several times and it will start working again. Sometimes dust can get in the contacts of the switch and cause them to malfunction.

    You can take a can of canned air as long as it has the little straw and spray around the button. A lot of times this will blow any dust out of the contacts on the switch.

    It is possible. But I would for sure try to blow it out with canned air. When you press the button, does it feel like it always did? Or does it feel like it has no give.

I have a 1997 mercury 25 el. it has quit firing. does this motor have a fuse, I cant find one


There should be a main engine fuse under the hood. But i think it is another electrical problem. Like ignition switch or coils.

The main fuse is under the hood, also an ignition key switch fuse or two, labeled AM1 and AM2. Check all of your fuses in this group.

The subwoofer for that system also powers the rest of the speakers as well as the
subwoofer as you probably know. Is there any power light coming on? Like on the subwoofer itself where ever the power light is. If not check for a fuse. If no fuse is visable you'll have to take the subwoofer apart, the plate amplifire. There will be screws all around the metal part on the back, you must remove all the screws holding it together. Most of these types of systems have the fuse inside on the board. Also sometimes the fuse does'nt look like a fuse, it could look like a resistor or a ceramic style disk capacitor. Yours will probably have a glass type fuse. If you don't see one look on the board next to the components on the power supply board or if all together look near the transformer area for a F meaning a fuse. /there will be letters and numbers next to each component eg., resistor, capacitor, diode, etc. If you find a glass type fuse replace it with the exact same rating which will be on the end of the fuse on the silver ends of the fuse. If it's not blown you'll need to test to see if your getting voltge out of the transformer. You'll have to have the DVD unit hooked up to it, you don't have to have any speakers connected. The cable from the DVD unit to the subwoofer is what tells the amplifire on the subwoofer to turn on. You could have a blown amplifire IC. I don't know what type of ouput amplifires this uses but I'm thinking IC and not seperate transistors for the output amplifires. You might have one of those blown and if you do then the whole system wont work. Hopefully if that is the problem you'll see a burnt mark on the IIC itsel or some type of burnt spot on the board somewhere to lead you in the right direction to the problem. It could be as simple as a power supply capacitor, who knows til you get into it and start looking around and testing some things. If you don't have the knowledge to do this I am the cheapest electronics business in the USA. It's not a bad system, CrutchField sales it. Also I can waalk you through the steps to narrow the problem down. I help people everyday. You can contact me at ampman37@gmail.com. I can then give you some more info and my business phone number if you feel up to doing this. It's really no big deal and I find that most of my customers who have never done something like this love and learn some electronics and now fix some other stuff they had laying around. I'm here to help. Thank you for contacting me, have a good day.

Having taken the xmas decorations down i moved the telly stand so that we could clean around the back unfortunately my wife accidently knocked the telly and everything went off it even blew the main fuse...


Blowing your fuse means you have a short circuit my friend. Even you replaced the fuse again and again it will do the same thing unless you isolated the problem. Blewing your fuse happened because it is a guard to avoid further damaged to you and your property. If you haven't a fuse fire will occured in the blink of an eye (thanks for the fuse) This is quit technical so I've advice you to look for a qualified electrician to isolate the cause of short circuit.

Cant get my 50cc scooter to fire up-no spark. any


  • Do you see spark? If not, check the side stand kill switch. It kills the engine so that you don’t start out with the side stand down. If broken or out of adjustment, it would kill the spark. Check for a broken wire at the side stand switch and coupler. Try moving the side stand kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it.
  • Is the handlebar kill switch on? Is it shorted out?
  • Check the fuses.
  • Check the operation of the ignition switch and all kill switches with a volt ohmmeter. Check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires?
  • Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral switch wire on center or side casing.
  • If still no spark, get CDI system and coils checked at the dealers shop.

My aprilia rs125 2007 jus cut out on me and wont fire up again


  • Start with a new spark plug. Now do you see spark? If not, check the side stand kill switch. It kills the engine so that you don’t start out with the side stand down. If broken or out of adjustment, it would kill the spark. Check for a broken wire at the side stand switch and coupler. Try moving the kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it.
  • Check the fuses. How good is the battery? Try a jump start from your car battery. Is the handlebar kill switch on?
  • Check the operation of the ignition switch and all kill switches with a volt ohmmeter. Check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires? Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral switch wire on center casing. If still no spark, get CDI system and coils checked at the dealers shop.
  • Are the fuses good?
Can I get a “very helpful” rating on this answer? Thanks!
