Question about Cyberhome CH-DVD 300 DVD Player
Dont know what is up with this but the power will not come on
One of the previous posts is correct. There was a problem with Electolytic capacitors about 4-5 years ago, which is suppose to be fix now. Many companies tried to get in the business, but did not have the proper formula for them. This left the caps unstable. The caps could last for a week or for years before failing. This affected a lot of electronics from the high priced models to the cheaper. My computer at work (a Dell) and at home had the same problem. There is not a way to tell if a cap is from a bad lot, although there probably a list somewhere. When I'm fixing one I replace all the caps that are from the same manufacturer and same value as the blown one.
One day at work I saw a CyberHome 300 in the recycle bin (someone probably brought it in to fix it and failed). I pulled it out and of course it would not power up. Knowing about the cap problem, I opened it up and sure enough 2 caps were "pillowed" on the top. When a electrolytic blows it may vent out the top creating a noticeable bulge on the top. Replacing the two caps, the unit works great. If you'd like to know more email me at [email protected]

I fixed mine, open the unit look for bad caps, they look like soft drink cans. Usually the tops of the bad ones are pushed up. Just heat up the solder connection with a solder iron pulling up on the cap to remove it.
I found a 1000 uf 10v cap was bad. It's best to replace
them with one of a little higher voltage rating, I installed
one rated at 16v (16 volts).
You should be able to find these at radio shack.
