Power supply problems. There are many reports on this site for problems related to the cyberhome dvd player, one of them mine. Here is what I found. The dvd drive was ok it was the power supply that failed after a power surge. The power supply is a flyback power supply using the viper22 switcher by STM Microelectronics. you can download the specs with a schematic diagram simular to the one in the cyberhome unit. I wound up replacing the shunt regulator (TL431) Optical coupler (PS2561-a-1) , the 2200uf cap and the 1000 uf cap. this brought the 5 volt output to 5 volts which was the problem. The parts can be ordered from Mouser Electronics.
1000uf @ 10 volts PN UHE1A102MPD
2200uf @ 25 volts PN UFW1E222MHD
TL431 PN 512-431CLP
PS2561 PN 551-PS2561-1-A

Warning: The high voltage side of this power supply has 120 VAC and 161 volts dc when energized. thak precautions when measuring the voltages on the output. Good luck

Not reading the disc.

There are two common poblems that occur with the 300 DVD player. Either the machine will not power up at all and the power indicator won't work or after a disk has been inserted the on screen display will say "loading disk" but then say "bad disk".
First remove the top cover secured wih screws, you will now be able to identify the power supply board. At the output connector measure the 5 volt output with a voltmeter. If less than 4V, than the unit will not work properly. The filter capacitors are bad. Replace C10, 2200uf@ 10V and C11, 1000uf@10V. Because of the limited space provided, use capacitors of the same physical size. Do not try to pigtail a larger cap in its place. The circuit will not operate properly. I can supply these if you can't find them locally.

Unit will not turn on. Does a bad fuse cause this?

There are two common problems that occur with the 300 DVD player. Either the machine will not power up at all and the power indicator won't work or after a disk has
been inserted the on-screen display will say "loading..." but then say "bad disk".
First remove the top cover secured wih screws, you will now be able to identify the power supply board. At the output connector measure the 5 volt output with
a voltmeter. If less than 4V, than the unit will not work properly. The filter capacitors are probably bad. Replace C10, 2200uf@ 10V and C11, 1000uf@ 10V. Because of the limited space
provided, use capacitors of the same physical size. Do not try to pigtail a larger cap in its place. The circuit will not operate properly. I can supply these if you can't find them locally.

Cyberhome CH-DVD 300 DVD - YELLOW light indicator of what problem?

Marlin P Jones & Assoc. Inc.. has a 5V 2.2A /12V 1.5A cord power supply that will fit into the space where the original power supply was! Lists for $6.95 but online price was $2.95. Works great! Connect 12V supply to the yellow lead and the 5V to the red lead of the output connector, black is ground, common to both supplies. Use QC terminals to the power cord input terminals, remove the cable clamp and the power supply will nestle beautifully in the space without need for support. (Remove the old circuit board plastic (3) and rear brass standoffs and use the front brass standoff for the output cable shield ground connection. (Part No. is 15955-PS) I bought two because I have a 2nd Cyberhome CD-DVD 300 which hasn't crapped out yet.

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.

Wont load any DVD'S

It is possible that the power supply is not providing a solid 5 volts.
Many of these units had problems where the 5v is too low (4.9).
In most cases capacitors can be replaced to correct a low voltage situation. Be sure to use 16v capacitors in place of any 10v.
