Question about Coby DVD-224 DVD Player
What do i do my dvd player will not play my dvds?
Blandenah, As long as you have the cover off of Coby224 please check the elecrolytic capacitors on the power supply board screwed down right next to the Disc Transport mechanism.
Make sure they don't have any swelling of the aluminium can housing. please get back to me on this item if you spot any expanded tops on the filter capacitors. Possibly you could get a
friend with DC voltmeter to check for the three dc voltages unit requires.. +5v for logic +12v -12v for Mechanical things like motors and analog electronics and sensors. If someone checks the voltages, they better be very careful!!!! It is a line operated
switch-mode supply and voltages on the line side could be as high as 200volts DC not to mention the input line being 120vac. It could possibly kill you!! But that's worst-case scenario. Good luck. Please notify me of results of your investigation firstname.lastname@example.org

First check you any other disc in the dvd player.then also try the same dvd disc in any other player.then confirm exactly the problem.if its the dvd player that is having the problem then it must be because of faulty lens just follow this instructions.
Step1Make sure the laser pickup lens is actually the problem. There are a wide variety of reasons that a DVD player might not read a disc efficiently. The disc could be scratched or dirty, for example. Test the DVD player with a disc that you know works before trying to clean the lens.
Step2Purchase or borrow a lens cleaner disc and try it first. You can find these things really cheap at any large department store. They usually get the job done well. However, you may need to clean the lens manually if the store-bought cleaner fails.
Step3Remove the outer casing of the DVD player. Remove the screws that mount the top casing onto the bottom of the DVD player and slide the top casing off. This will expose the DVD deck, which houses the laser pickup lens.
Step4Find the lens. The lens will be glass and under the DVD clamp. The lens will probably have a blue tint to it. If you are having trouble finding the lens, you could shine a light on the components and watch for the reflection.
Step5Use a cotton swab and some isopropyl alcohol to gently wipe the lens. Just a quick scrub will do. Dry the laser pickup lens with the other end of the swab.
Step6Give the lens a few seconds to dry and replace the covering of the DVD player. Test the efficiency of the player. If necessary, repeat the process.
