Question about Televison & Video

Coby DVD-937 home theatre system - I'm afraid I've placed the unit over my dish network system and the DVD has overheated. Consequently, after turning on the DVD I lose sound after about 4 or 5 minutes. What is my problem and how can I fix it?

Hi,

The first thing i would say is that the only solution to fix this problem is to get it repaired or replaced.
If it is running hot it certainly could be dangerous.
Actually, I would not bother to do any fixing on it as the cost of dvd players has gone down so low that you can replace them for less money than the cost of service.

For example, you can buy a very nice dvd player on sale for $28 and up.
If you wanted to get the Coby set serviced I am sure it will cost over $50 to solve the heating problem - and maybe more.

Goodluck,
Please don't forget to rate the solution.

    Overheating probably has something to do with your main circuit board which has to be replaced.

    I believe that the fan does not seems to be spinning when a DVD or CD is playing, and hence the top of the case gets very hot.

    So at this point I would consider opening it up and trying to add a new fan.But definetly a replacement will be much cheaper rather then repairing it by urself.

    You must also have some experience in electronics background before attempting to do these stuff.

Coby DVD -937 home theater system. Pushed power off but will not turn on again when pushed. Outlets are good.


Could be that the power button is worn out...it is a common problem with computers as well. They are not wear tested for durability. Some of the reviews i had read concerning the model 937 are not the best, i have just bought a used one myself, and it was only used once..so i was told, however, not all channels working for speakers. The choice is, do you send it in for repair? or just buy a different brand altogether and ship that one back? you need to get estimate from electronic repair as to cost. that is the primary problem,. or could be board is shorted out in unit. in that case, get refund, or if extended warrenty have replaced.

Best of luck....

I'd be taking the unit back ASAP for a check and swap over. When plugged in and powered up all you need is to press eject to get it open. take it back to the shop and they will confirm the problem. Don't hesitate!!
Happy Shopping!

I can't get my coby DVD 937 to play sound while watching tv. It works fine while playing a DVD or CD????


there should be an input line of just audio cable hookups (one red and one white) that you have to run and an output cable from your tv audio output of just red and white. make sure the tv says output or line out and the surround sound system says input or line in

Question: how do you connect to a cable box?


That Coby DVD-937 only has Digital Audio outputs rather than inputs, which is very strange and complicates our problem immensely. You will get 5-channels with DVD or radio play, but getting 5 channels for TV is not possible without additional equipment.

The manual for the Coby mentions a "Digital Decoder Amplifier," which would work. You would connect a digital audio cable from the area marked "Coaxial" on the back of the Coby to a digital audio IN on the back of an external amplifier. You would connect the speakers to this amplifier, instead of directly to the back of the Coby. Then you would need a cable or satellite box with digital audio outs (fairly common nowadays) to another digital audio IN on the back of the amplifier. The cable or sat box you may have already, but you may need to purchase such a "Digital Decoder Amplifier" or other digital amplifier with appropriate speaker wires and 2 digital audio input slots (not to mention two digital audio cables). Fairly complex. Possibly expensive.
