This error "disc error", "no disc present" or " can\'t read cd". This all error are related to lens problem. If the lens is dirty or if the lens is got cracked or if the lens is getting blocked then it can happen. The lens is very thin glass material. You can say the lens is the "eye" of the unit. If the eye is dirty then it will not see the object. The unit needs to be opened carefully and this lens has to be checked. If any dust is collected clean it. Using the cd lens cleaner helps, but if the dust is got stuck hard or if its any other internal part then the lens cleaner will not help. If the lens is got cracked then the lens assembly has to be replaced.
You can use dry tissue to clean the lens. once the unit is opened. ------------ ------------- In most of the cases, this problem is not related to cd.But still get the cd checked in any other player too, this will confirm the fault. Also try other various cds in the boombox cd player and confirm. But if the cds not playing in other player too then its faulty cd.But this is very rare. Most probably the fault is related to boom box cd player. In the boom box cd player unit there are two main parts. One is cd spinning motor and other is cd reading lens(its also called "EYE" of the cd player).But many times the cd spins internally and does not play. If you can hear the noise of cd spin inside then its lens problem and not the motor. But if there is no spin noise in the unit then both lens and motor are to be checked. The motor is not spinning because its short/blocked or its connections are got loose. It has to be checked. The lens is not reading the cd, because its got dirty or its got cracked and faulty. The boom box cd player lens is made up of thin glass and its very delicate. Many a times dust gets collected on the lens, so the lens stops reading the cd and it do not play. Some times there is no dirt on lens but it gets cracked, if by mistake any pressure is applied on the unit or up-side down cd is placed in the tray or internal short circuit has occurred. These are few possibilities of lens not working. But in most cases its dirty lens causing this problem. SO open the tray by pressing the eject button, then unplug the unit from main power outlet, by keeping the cd tray open. Then take air blower and blow air in the unit. Please remove, if there is any cd in the tray while blowing air. Just blow air for few minutes. Then take a dry tissue and clan the cd placing tray externally and then reconnect the power and see, if that is helping or not. If the problem is same as before, then disassemble the unit and clean the lens manually by hand using dry tissue paper and then see if its helping. But take care while cleaning the lens with dry tissue you doesn't apply too much pressure on lens or any other parts. Also before removing any screw to disassemble the unit. Take a marker with you ready. Just mark the position of parts and screws before removing. If you have a cell phone with web cam in it then take a photo of the internal parts before moving any parts. Disassembly is not very hard but reassembling is not easy. So this pictures and marks with help you for reassembly. ----------But if lens is cracked internally then the lens assembly has to be replaced. If motor wires are loose then you can easily get it re-soldered by soldering machine. You can get it replaced from local cd /dvd player repair center. They have these parts with them. --------------- This should help. Thanks. Helpmech.

SOURCE: I have a zs-s41p boom box that takes an ipod and CD. I'm not getting any sound at all. Radio, ipod or CD player. Help!

Check the back of the unit for possible shorts in the speaker wires, no change! take the boombox to a service centre for a repair estimate.
