Re: Infinity PS-12 Powered Subwoofer Fired Amplifier



you can check that sub with any of the channels from the receiver?? I assume your hooking this sub amp up to something? Sub output of receiver? Use any of the 7 speaker outputs on that to test woofer....

Re: Infinity PS-12 Powered Subwoofer Fired Amplifier

I've read the entire thread now. I thought my amp had obvious signs of what was wrong but all I found was a little browning by the resistors..... and no one mentioned anything like what is happening with mine ..... got this wierd zap sound happening.

Should I just start replacing caps anyway?
I get nothing out of it at all, have never seen the woofer move...

Re: Infinity sub amp and Onkyo 2 ch reciever

Ok sweet, i just found the ps12 amp thread which is the same amp as i have. I dont have the obvious cap burning areas though, but part of the board is brown.

Hey all, looking for some advice

First i have an Infinity sub amp from a ps10 that turns on, makes buzzing noise louder and louder till it shuts itself off. Noticed someone on ebay fixes them so it must be quite common.

Anyone have any idea on what goes out on these?

2nd i got a 2 ch onkyo tx8050 reciever that has never had any speakers hooked up, it was used as a controller for an old bose 5.1 amp they sold way back in the day, so only thing used was the 2ch preouts fed from the optical from tv. It turns on with half dim display and then protects...

Few tvs were in a house hit by lightning.

This one was fine for a month, now i get this rainbow effect on the top row, can unplug that ribbon and rest of tv is fine.

Would this be caused by buffer or ymain? or how do i know if the panel is bad??
