Question about Logitech Z-2200 Computer Speakers
Hi, and thank you in advance for reading :)
I've had my logitech z-2200 for about 4 years now. Suddenly the other night the left speaker stopped working. I found out that, theres nothing wrong with the satellite speakers, but the output for left channel that is coming out of my sub, isn't working.
Any idea, what went wrong or how much I'd be looking at, if I was to take it to a repairing shop?
The exact same thing has happened to me,, the left channel just stopped working. I am in process of changing the audio amplifier chip for the left channel a TDA 7296. Its a fairly inexpensive gamble at less then 5 bucks for the chip. It is fairly complicated amplifier chip with a built in mute, standby and thermal shutdown protection features in the chip so it is possible any of that has gone haywire the chip would not output properly if so. Also found on the same channel a small choke a three turn coil that was dislodged when they added silicon to the board and it pulled the choke lead right off the board. I would presume this alone would not be the problem but could have lead to the amplifier going bad if it truly is.
Evertyhing else on the main board seems to test well and nothing is standing out as a problem. Rollin the dice. Waiting for a chip in the mail,,, time will tell.
