It is very possible the internal fuse burnt out. If not the fuse, then possibly the power supply burnt out. You can test the power supply with a voltmeter.
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-APower supply problems.

Hello,
the reason your player wont come up is because there is a problem in the power jack, it got exposed to a very high current.
try to open the player and test the transistors with a meter.
you will detect that which has the fault.
then you can replace it or change the power board completely.
