Question about Cyberhome CH-DVD 300 DVD Player
I noted the comments earlier by a Guru and checked the voltages at the connections going to the DVD player. I got 2V & 120V instead of 5V and 12V!!! Should I just toss the player and get a new one at this point? I can change capacitors, but I am far from being even an apprentice at dealing with electronics.
If the 120V was at the connector with black and white wires, that's normal - it's the line voltage.
2V at the connector with black, red, and yellow wires suggests that one of the electrolytic capacitors is partially shorted. If you see one of the electrolytics that looks burned or bulging slightly at the top, you could replace it.
If you're not sure what an electrolytic capacitor is, I suggest giving the player away free or selling it for $1 on craigslist. It's an inexpensive player, anyway.

Yep, toss it. 120V going to the DVD electronics will have fried the electronics. Thats amazing since the power supply should have been designed so that, no matter what, 120V line voltage should never end up being present at the low voltage output sides of the power supply. Scary, isn't it?
