Denon DN-S3500 will not read cd red light @ front keep flashing
Hi, firstly check that the discs are not too scratched and be aware that CD's read and play from the inner diameter to the outer diameter. CD players are really finicky devices that can be affected by the slightest bump and also temperature and humidity changes. Sometimes decks have a humidity sensor embedded in the circuitry. So, all that being said, firstly just turn the set on and let it sit for a while to heat up and dry out especially if it hasn't been used for a while. Then, take the lid off and check for broken drive belts that actually spin the disc. (You may be able to hear the disc spin without the top off). After that the laser itself will have to be cleaned, adjusted and the current checked. Lasers do wear out and sometimes increasing the current to the laser will make it read for a little while longer. You will need the schematic diagram and some decent equipment and knowledge to achieve this though. Since they both don't work, and you got them for free, they might be good experimental pieces but, in my experience they are never 'time' worthwhile repairs. Good luck. Cheers
Aiwa Z-L700 cassette player will not work but CD player is fine. Is there a simple solution please?
The complexity of the solution depends on the problem. The drive belt or pinch roller may be worn or have a hardened surface. If the tape doesn't turn at all or only very slowly in any function, verify that the tape drive motor is running and that the belt is turning the pulley(s). If the tape tends to tangle up, check the pinch roller. Sometimes cleaning the roller with a cotton swab dampened with rubbing alcohol will work, but if it's too hardened, you'll need to use rubber conditioner or replace it.
If nothing at all happens when you select the tape function, there may be an electrical problem such as a dirty contact on the function switch or a broken wire in the tape mechanism.
This is far from a comprehensive repair guide; it only covers the most common issues other than broken plastic parts. "Will not work" is too general to provide more than that. Cleaning the pinch roller and its drive pin can be done through an open cassette door; everything else most likely requires taking stuff apart, observing operation and perhaps making voltage measurements.
My Pure Sonus 1Xt will not work
I thought my Pure Sonus 1XT was knackered as it would only show a blank blue screen and not respond to the buttons.
But by trial and error I found that if I disconnected it from the mains power supply for TWO WEEKS (one week was not enough) it would restart correctly, and would stay ok so long as I did not disconnect from the supply, and so I used only the standby button to switch off. If I did disconnect, it meant another two week wait.
No idea why this works. Mine did have a faulty power supply at one time (genuine Pure) which left 15v on the supply, rather than the 9v that it should be.
Worth a try before you take it for recycling.

That is caused by the lens or the laser head: dust has settled on it and it's blocking the reflection of the laser to the sensor = no signal is detected so the player thinks that no disk is there.
Because this has happened so long time ago and nothing has been done to clean it i doubt the dust can still be cleaned - by now it has been probably baked in the plastic of the lens.
All you can still try to do now is to try a manual cleaning: dismantle the unit completely (take out the sides, take out the rear, lift the top and remove the transversal bar) and access the reading head - clean the lens with a can of compressed air from all parts and then wipe its face with a q-tip.
