Question about Aiwa CSD-TD69 Cassette/CD Boombox
This came on in a blink of an eye. Unplugged it when I moved, (was working just fine) brought it to the new house (no damage/dropping or anything like that) and it simply does not turn on now. I tried a different same size cord--same thing--will not work. The house outlet works fine. What can I do? Is there a fuse that might have blown? Anything you relay will be gratefully accepted. Thanks!
My friend gave me his GPX K1007 CD/CD+G Karaoke Player to fix. Here is what I found. Firstly, its a typical piece of consumer electronic crap! There is an el-cheapo little bridge rectifier coming off the lower voltage outputs of the main transformer: 4 diodes and an electrolytic capacitor. This tiny little circuit board I see (after I managed to get the thing opened) appeared to have suffered some kind of electrical upset (black smuges) and yet I finally concluded that that is NOT the problem. The transformer (E190246 HF-41217L2TN) for some damn reason is not accepting any current in its primary winding. It is just an open circuit, which I cannot for the life of me understand. I think perhaps if I can just get replacement for this (apparently pretty shoddy) transformer it might start working again. I just have one problem. I know that we ultimately want 12 VDC onto the main board of this thing. What kind of volts AC do I want to come off of this transformer so the bridge rectifier circuit will convert it into 12VDC. Do I want 12.6 VAC on the secondary, since this is typical of the transformers I see advertised? Also, what kind of amperage will I need? I would have to know that so I know which type transformer to buy to replace the one in the unit.

I have a RCA RCD152 boombox. Sometimes it helps to take out all the batteries, especially the 3 AA batteries. Also unplug the power cord. Try waiting a minute before putting the batteries back in. It might help. It worked for me last night. From previous experience, I think it will happen again, so I will take out all the batteries again, put them back in again, and hopefully it will work again.

I would Suggest Using it at Home ONLY!

We have had same problem. Seems to be something to do with timer setting. Will be working fine and then stop all of a sudden, often mid-song. The LCD stops lighting up and nothing works. Unplug it for a day or two, plug it back in, and then it starts working again! Has happened to us twice. Can't find our manual for this product, so don't know how to fix it.

I have the same problem. Works with batteries but not AC power. Seems like power supply or micro switch which detects AC power cord to enable/disable batteries. The last 3 SONY products I purchased had problems. Sony is living on their past reputation. No quality any more. Never again for me.

Mine did the same thing. I maybe used 5 times. I took apart and it appears that the primary side of the transformer is open. I will confirm this with batteries. If the batteries work I will probably find a power supply and solder the wires to the contacts where the batteries connect.

Did you try with batteries? If that works, the internal power supply fails. A handy person with basic knowledge of electricity measurement, some good screw-drivers, a multi-meter and a soldering iron may solve most probably the problem.( You find persons with such disease at most unexpected places) Getting spare parts in case of need maybe a little more difficult.
