A lot of "aged" problems relate to the power supply with this type of unit. If you are a handy chap and know what capacitors are you will find that finding and replacing the "dry" caps in the power supply will fix most problems including streaky pix and crackly audio.

My amp stopped workin, when i turn the stereo on, the green light is on, then when the music starts to play it turns red and stops working,


The red light on amplifier relates to power supply while the green light is indication of sound functionality. An amplifier that allows sound to generate should display both red and green lights. Howeever, some amplifiers would display only green as long as the sound is functioning.

Solving the problem

First, a red light still on means the power connections to the amplifier is fucntional least requirng repairs.

Second, the green ligh should turn on once the stereo were tuned up to produce sound. If the stereo is still on only least produce sound on the amplifier, check on the connection wires between stereo to amplifier that may have disconnected due to woofing or dubbing sound generals with unfirm wiring.

Red light above display flashes but no functions working


hi Dave
I'm not the most technical person in the world but I think I've fixed mine which had the same problem this afternoon, which is how I came to find your message!
Right.. here's what I did. It would appear that you have some kinda mechanism jam (even if there's no disc in it), so... please excuse my non-techie terminology throughout.
By the way, I probably don't need to tell you this but unplug the unit from the mains first or you might light up if you touch something!
Working with the unit facing you (control side), remove the two small screws at the back (on the metal flange) and two medium screws from the right hand and left hand sides of the main casing, then slide it off from front to back so that you can see inside the recorder. If you look in and down at the CD tray transport mechanism you should see a white plastic 'cog' wheel on the left hand side of the unit near the bottom 'floor' of the machine. Carefully rotate this wheel with a finger CLOCKWISE (pushing the wheel from front to back), slowly and gently - don't force it - and you should see the CD tray mechanism and gubbins start to move; keep rotating until the tray comes right out, or as far as you think it goes. Then, plug the unit back in, and switch on - the tray SHOULD then be taken back into the machine, the red light will flash, and the display should come on. As I say, mine has, so try it and I hope it works for you!
All the best (we'll beat these damn machines yet!)

Clean the white areas on the tray with a light solvent cleaner like windolene/windex liquid. Also try giving the tray a helping hand as it is started to be fed into the printer

Tray won't open, no buttons work


Return it. do not open it up or you will void any warranty. There is either a disconnected cable or a logic/power problem. In any case, a new piece should work out of the box.
