I need instructions on how to transfer cassette from a boombox without headphone jack to PC.

The problem is that there is no sound output you can use if it has no headphone jack. If the aux jack was an out, then you could use that. It is possible to make a jack socket, by breaking into the speaker connections. But you would need a soldering iron and a headphone jack socket to do that. You would also have to build the jack into the unit. As I don't know if you can do that, I would suggest finding a cassette player secondhand that does have headphone jack on it. There must be plenty around since cassettes are not that popular now. If it's a commercial music tape, it would probably be cheaper to buy the digital version of it. But if it is a personal recording, then the cheap cassette player is your best option.

Receiver says headphone mode no sound

Check to see if the end of a headphone has been left in the headphone jack. If so, remove it. (Sometimes the break off and are left there).

If the jack is empty (the easiest way to tell is to insert headphones and see if they go in all the way), then open the receiver and see if you can disconnect the headphone jack. There is a sensor in the jack itself that senses when something is inserted. If it's stuck in the "closed" position it may think that headphones are inserted.

Other than that you may need to update the firmware or reset the thing back to factory defaults. There is usually a button on the back for this. Hold it in for a minute after you have unplugged it. Then plug it back in and test.

I have a 2002 Chrysler Town & country and I can't get the sound to work for the Vcr/player Without headphones. How do I get the sound without the headphones?

I had one of these and it turned out to be the headphone jack, when you put the headphone plug into the jack it disables the speaker and when you unplug the headphones it enables the speaker. There's a contact in the jack and it is probably stuck to headphones. The jack may need to be replaced. Try and wiggle the plug a few times but not hard as it may break from the curcuit board.

I have sound from my headphones but nothing from the speakers, pls help

So it IS acting like headphones are inserted even without them. Stop messing with other connections. The jack for the headphones has spring-loaded normally opened and normally closed contacts that are designed to disconnect the speakers when the plug is inserted. Perhaps the NC connection isn't making good contact on headphone removal. With the Volume turned to soemthing NOT LOUD, repeatedly insert/remove the jack to see if it makes any difference; or with power OFF squirt a little tuner cleaner in there first and repeat with the headphone jack.

How can I get headphones to work with my Symphonic WF203 TV?

This set doesn't have a headphone jack, nor does it have RCA audio output jacks. Without one or the other, you're out of luck connecting headphones to this TV.

I remember a product some years ago that allowed adding headphones using a small microphone placed in front of the speaker. This was hooked to a little amplifier that ran the headphones so the volume could be independently controlled. It was marketed as a way to let "hearing-impaired" family members listen to TV shows without needing to make it uncomfortably loud for others. I haven't looked, but something similar might still be available. It's cumbersome, though, and needs power, plus maybe being costly if you find one.

It's possible to add a headphone jack, but you need to know how to do electronic soldering. Find a spot on the case where you can make a hole and mount a headphone jack, then wire it to the speakers. If you want the headphones to cut off the speakers when plugged in, you need a switching jack, and the speaker wires need to be cut and connected to the correct terminals. The switch built into the jack then disconnects the speakers when the headphone plug is in. If you don't need to turn off the speakers it's a little easier. You just need to wire from the jack to the speaker terminals. I've added jacks on quite a few sets. If you don't feel up to it and don't know anyone who is, you can see if a TV shop (if there are any left in your area!) would do it. (The shop I used to work for charged about $20, including the jack, but that was over 10 years ago now.)

Good luck, and thanks for using Fixya!

I have a mac air and I am having volume problem. When I attempt to adjust the volume I get a circle with a line over it. Also I can no longer watch video since this problem occur. The video would load play...

The problem is that the headphone jack for you Macbook Air is a copy Analog (standard headphones) and Optical (toslink) jack. The jack has a small microswitch that detects when the cable inserted into the jack is a metal analog connector or a fiber optic toslink cable. The reason your seeing the "NOT ALLOWED" sign (circle with a slash through it) is because you cannot not adjust the volume on the sound when the output is in DIGITAL MODE. To verify this, drop down the jack cover on the side of your macbook air and place your index directly in-front of the headphone jack about 1/2" away from it. Is you finger glowing red? That's because the fiber optic LED is turned on and Mac OS X thinks that there is a toslink cable inserted into the jack.
This is a known hardware problem with that type of combo-jack and affects a lot of other Macbooks, as well.
If your Macbook Air is still covered by Apple Care, take it into an Apple store and have them replace the jack. I know this is a pain, but it is the correct answer.
If your Macbook Air is NO LONGER UNDER WARRANTY, you can attempt to fix this yourself, but be warned, you could break stuff!
Here is a thread at the Apple support forums discussing this issue:
The above link is good background reading and will help you understand the issue further. The short answer is that many people have inserted a toothpick (other similarly sized NON METAL object) into the headphone jack, wiggled around until the microswitch is clicked off, then normal audio resumes. My 2009 Macbook Pro 17" has the same issue, but I have found that I can take a regular pair of headphones, insert the jack, wiggle it, remove it, reinsert, remove it....and repeat this process until the switch gets toggled. It's annoying, but I have to do this until I get home and can send it back to Apple for warranty work.

Need how-to on replacing the rear motor mount

"The" motor mount implies one of the three (actually the rear on is a transmission mount).
Loosen the bolts on the mounts that you are keeping.
Next, place a 2x6 about 1 ft long under the oil pan and place a jack under the oil pan and 2x6 board.
Apply pressure (just a little) to the jack.

Now, remove the bolts that hold the bad motor mount. Apply enough lift on the jack to get the engine weight off the motor mount (and no more).

Next, knock out the bad mount and insert the new mount. Insert the bolts (hand tighten).

Next, lower the jack until the block rests on the new mount. Tighten the other motor mount bolts and the new mount bolts (torque to about 35 Ft. lbs.)

You are done!

No speaker sound

Unfortunately, these small jacks are not very durable.
They can be constructed to turn off internal speakers when a plug is inserted into the jack or not. There are normally small bumps on contacts in the jack that are pressed upon when inserting the plug and if their spring qualities are less than good, they stay somewhat bent after the plug is removed leaving one or more channels dead.
The cost of a replacement jack is miniscule (any electronic supply that caters to hobbiests will have them) but the replacement may require extreme care. The jack could be a board-mount type with angled leads that are inserted through the board or could be attached by thin wires. With care, the board mount type is the neatest to replace but one should have some soldering skills and a good iron to avoid damaging the circuit board. The wired type makes a messy repair and demands even more skill to keep stray wires from shorting each other and one always risks breaking the thin conductors while handling them.
