Tip & How-To about Audio Players & Recorders

Testing The Speakers

After narrowing the list further, you should be ready to test your speakers. Therefore, it is better to buy the speakers from your favorite electronics store. Many of the speakers can be as specific as impressive, but few of them are right for you. Find one that's best for you, so you can buy and bring home the speakers of your brand new computer.

speaker buzzes but it plays no music


Blown speaker driver. Buy a new speaker of the same frame size and ohms (Omega character symbol) usually 4, 8 or 16 ohms. Contact the manufacturer if its an expensive name brand. Check the manufacturer's literature to determine the Ohms, it will be listed. You have turned up the speaker too loud and fried the magnet. Buy better speakers rated in watts RMS... the higher the number, the better.

I've had these speakers over 10 years. I had two stereo receivers burn up, and I'm now realizing it may be due to speaker issues. I bought a new receiver with a store warranty (which i never buy) and I had the same issue with it saying on the receiver display "Protect." When I read the manual it indicated it may be a short or something in the speaker or speaker wires. I changed wires, and now one speaker is working and another is not. Is it time to replace? I've already spent a small fortune to figure out what the problem MAY be. Anyt houghts.


You have to be absolutely sure that your speaker wires are intact and no stray wires are crossing paths with another conductor.

Beyond that, the best way to test a seaker is to compare them with a meter, reading their DC resistance and comparing that to their DC resistance specification, if known. If you have a meter, you could measure and call Boston Tech Support for the answer.

If there seems to be an issue, you could narrow it down to an individual driver or the crossover network. Then you'd have to source the parts and replace them...sounds like an ordeal.

So, if you're ready to do all that, and love the speakers, it should be a simple matter of narrowing it down to the offending component and repair it. If you're not interested in that course of action, there are several nice speaker models on the market that are equal to the Bostons for around $200. You've enjoyed them for a long time, so it may be time to move on.

LCD screen is cracked. Can it be replaced. I will pay fof it, and try to replace it myself. Thanx


It is often that the LCD Screen can be replaced but if you wanted to change or replace it, therefore you can buy it but it's rare to find some replacement. And then if you further buy a LCD replacement and then the price is the same with the price you buy a new one LCD Monitor, then much better buy a new one.
I tried that here buying LCD to my Computer but the same price to buy a new LCD Monitor.
Hope this tip might help you.
Good luck!
Please rate me.
Thank you.

Noisy left hand power output stage. Noisy transistor? No circuit diagram.


If the speaker is not blown, there must be an output capacitor. If no output capacitor, and you have a blown transistor the speaker will blow from DC current. You can further check the transistors with a multimeter. A transistor looks like 2 diodes and you should be abobe to test with a mulimenter like a diode test.
