Before doing anything else swap the speaker connections over to make sure that the problem is in the amp and not the speaker / speaker cable.
If that doesn't solve it then it is most likely an internal fuse blown on the amplifier circuit board - they are little tiny glass ones, obtainable from most tv repair shops, but it is important to get the right power rating. Also some of these fuses are 'quick blow' (go instantly there is a fault) others are 'slow' or 'time' blow - take a second or two before they actually blow - make sure you get the right one (timed usually have the letter T next to the power rating)

One speaker wont work


if u have experience with the soldering of the terminals then you can open the speaker casing of the sub woofer and then solder the right speaker input wire.

dont do this if you have no previous experience and DISCONNECT THE POWER SUPPLY before doing any work inside.

Right speaker doesnt have sound


1ST.-The right jack could be damaged!!
Usually, there is a [+} posaitve & [-] negative input\output to speaker connections. Not all [-]neg. is ground.Sometimes the [+] pos. is grounded. [The exception to the rule is that u SEE the black wire going to ground] the reason I am letting u know this is that u can test the INSIDES of the sound system.
If u can get inside of the unit. Cut the left speaker output [+] posative from both outputs. criss\cross wires.Place left speaker output to right speaker jack[ that does not work!!] & visa versa.If the [LEFT Output] stops working after u plug in the speakers,the internal RIGHT output is damaged. NEEDS TO BE TESTED
If nothing nothing changes.The left still works & the right still does not work, then it is the jack (shorted ?, opened internally ?)

Speaker Problems


Can you swap speakers and see if the left working speaker works when plugged into the right output?

If it does, then your right speaker is bad or the right speaker cable/plug may be bad.

If the working left speaker doesn't work on the right output, then I would suspect a problem in the right channel audio amplifier.

Please let me know if I can be of further assistance to you.

Good luck!
