Picked up a S.E.T. (Somebody Elses Trash) yesterday. Sign on screen said "Works Great - FREE". Sure enough brought it home, plugged it up and worked great, as advertised. Played for about an hour then turned off. Today, wife went to turn it on and only thing we're getting is a recurring "tick" about every six seconds or so. Is this indicative of a faulty flyback transformer? Opened it up and no obvious problems seen - ticking appears to be coming from the flyback transformer. No fried components or questionable solder joints. Any advice would be greatly appreciated. Unit is for mother-in-law visits (cheap is good!)

you probably have a capacitor that has dried up and changed value.

I'd test the HOT first though.

SET is a good one, I usually refer to it as Large Item Pickup. They have a special day once a year where everyone sets out large items that wont fit in their trash can. The city hauls them off for free on that day. Or someone else does.

Thanks for the quick reply. I need a little guidance to troubleshoot per your advice - what does HOT refer to? Is this the sequence detailed in the guide you provided?

Please help. I visited a site (tech-tips page, I believe)that described my symptoms exactly. Site advised replace Q4103. Have removed Q4103 from chassis, but need to know what to shop for to replace. Markings are

925I
30613
E B C

I know what the E B C is but cannot cross-reference a replacement from the other identification. I have an assortment of Radio Shack NPN and PNP transistors but have no idea which to choose.

Q4103 tested OK so I reinstalled. I have two photos and a short video of symptoms in action, but do not know how to post them. If someone can help, I'll post them and hopefully, with an experienced eye, make some progress. :?

HOT is the horizontal output transistor. I dont know what number that is on your board. Ive actually never worked on a ctc159, those are quite old now.

Were you able to try the troubleshooting chart that I attached?
