ive read all your comments about no power on DVD player... and you said that replace the capacitor of power supply... but im confuse... which one? i have a tester but how can i test the fried capacitor?
You dont ,,just replace c10,and c11,,,youll need a solder iron,if you havent done soldering before find someone that has done it before,,youll see c10,c11 stamped on circuit board.
See how much voltage your getting on outputs 12 on one side 5 on other

is there any power indicator? if none,look for the power supply board replaced blown fuse. if the fuse is blown with darkened color that was mean their is a shorted component parts in the PSU or in the main board.usually rectifier diode and regulator ic.hope this can help just let me know if you need further solution.
Never put any fuse in it and switch ON. It has some short with internal circuit, and should be repaired before installing a new fuse. The fuse use is as a protection device to protect the other circuit parts from further damage. If you will put an other fuse, and switch it ON again, you are making things more worse than present. Find out the reason for buring out fuse. If you can do it by yourself. Otherwise get it repaired by any experienced service personal. Never make it irreparable. OK.
it is possible that the power supply unit in the DVD has failed. You will need to open and ccheck, the fuse might be open and if a new fuse blows out then the SMPS unit is faulty.
Possible that the Sm driver IC /driver has failed. Possible also for allied components to have failed.
Or else you can change with a new unit.
It may be a replaceble glass cartridge fuse, or a fuse soldered to the power board.
Unplug, remove top cover, check and replace fuse. Radio Shack has reasonable coverage of fuses.
But - fuses usually blow for a reason. It could have been a power surge; it could be an internal failure. If the new fuse blows, it needs professional replair. Many of these are so cheap to make that it doesn't pay to repair them - replace it if the repair estimate is over 1/2 the replacement cost.

The fuse is usually blown when this happens. If you know how to find the fuse and replace it this should give you power on again. If this doesn't help then you may have had power surge and just blew the mother board. If this is the case then you may just need to get a new one for they are really priced low now.
The CyberHome CH 300 is a good, inexpensive DVD player with a power supply board prone to fail, because of a few weak components, especially if left turned on and not used.
Usually, if the power supply fails, the red light will not illuminate when plugged in, and of course not turn green when turned on.
If you have this specific problem, I can repair the power supply for $20.00. Contact me at FrancisH49@hotmail.com to arrange shipping and return of the repaired board.
