Cyberhome CH-DVD320 Doesn't Come On

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?

Cyberhome ch-dvd 300 player willnot come out of standby and willnot reset after holding reset for 30 sec


Possible failure of the processor. You can shut down, power off the unit completely. Allow time - few hours - for the voltage to drain off thereby resetting any error voltage on the processor. Now repeat the resetting when you power and if there is no response the chances of the processor or motherboard having errors/damaged components are high which will require a voltage/signal/logic trace in the processor

The cyberhome no picture when playing a dvd on the ch-ldv 712


Sometimes portable DVD players allow you to switch to a secondary TV for playback. When this happens it disables the primary screen on the portable DVD player.

Thats usually the culprit as to why that happens.

If you have that feature on your portable DVD player you should check it out.

Cyberhome CH-DVD 300 DVD doesn't work, Help! please.


It sounds like a common problem with these units, which is easily fixed...

Open the unit and look at the capacitors on the power supply circuit board, there are probably some bulging or leaking caps on it, just replace them and you should be good to go. You should replace them with a little higher voltage but keep the same micro-farad value. ie: use a 16volt in place of a 12volt.

Not sure, but I believe the 2.75 volts you have should be 5.0 volts.
May want to check capacitors on power supply.
The output connector on the supply may also be labeled with
the correct volatges for reference. COnstant orange light may be
indicating the +5v is low.
