Hi everyone,I have the infinity ps210 sub and for the last week it just shuts down with a thump and goes into standby mode while I am watching tv then it goes back on in a few minutes and continues to do it every 45 min to an hour. the sub is only a year and a half old and now i started doing research on this problem and I think it might be a bad capacitor, or does anyone have any advice as to why this is happening? is it worth having it fixed or am I going to continue to have this problem? also what would be a good match if I was to purchase a new sub I have the onkyo 607 receiver with infinity primus 162's L&R and surrounds and the primus 350 center.do I have to stay with an infinity sub or can i go with a different make? Thanks all for the help and advice.
