Question about Cyberhome DVD320 DVD Player
I am not sure exactly what you mean here; do you mean the whole unit is dead? no functions? no front LED? If it is dead, the 'blown circuit' after replacing the fuse would be the power supply. Chances are, there may be several short-circuit/leaky components within this area.
IC regulators, power/chopper transistors, diodes (may be leaky or shorted), resistors (fusible and standard colour-coded types) may be open-circuit, and of course a whole lot of electrolytic capacitors may have leaked/failed. In other words, it could be an expensive repair job if you were to take it to a workshop and had them fix it. The most likely culprits in this instance would be the electrolytics; these capacitors may be poorly engineered. so they leak or burst their vents (the impressions in the tops of the caps split open and electrolyte comes out). When these caps fail, the subsequent result is increased DC voltage being passed through the lower output rails (due to decreased DC filtering) and they often take several other parts with them. Electrolyte is highly corrosive, so if any gets on to the copper side of a PCB, it will eat the track; which could render the entire board U/S. Let's hope that is not the case here, and hope the surface mounted components on that side are not affected in any way. It might be something simple, which a competent technician with adequate facilities and equipment can ascertain.
BUT - you can submit it to a service centre/workshop, and obtain a quote on the likely repair/parts cost first, this way you can make a decision as to whether it is economical/worthwhile repairing or not.
Or if you have some technical knowledge of basic circuits, you could probably opt to replace ALL the electrolytic capacitors (uprate their working voltages and values where necessary, whilst observing their polarity) and perhaps change the IC regulator(s) as required (assuming you can obtain the correct type and voltage rating of these). Don't forget to check the resistors and diodes for leakage (out of circuit if possible).
I have yet to find a power supply in any appliance manufactured recently with high quality low failure rated components on it.
If when you get the workshop quote on possible repair(s) for this unit, and you find it a tad high, consider cutting your losses and perhaps buy a new DVD player (or a recorder if you want one) with extended warranty - if you do; but only as a last resort.
Of course, all this is entirely up to you. The power supply is the main problem in this unit.

most likely you will have to remove the louvers or trim above the cooking cavity to get to the fuse, look for screws holding the trim/louvers on, if no screws are apparent, the piece may slide to the left or right and pop off.
Unplug your microwave. Although it might seem like no electrical current could possibly be running through your appliance, it could still have stored electrical current somewhere in the system. Be safe rather than sorry and unplug it before you begin.
Find the wiring diagram for your model of GE microwave. You can contact GE directly to get this if you cannot locate your owner's manual. Note the fuse locations and get a screwdriver. Some GE fuses are located under the louvers, while others are located in the door.
Open up the microwave and locate the blown fuse. Sometimes you cannot determine a blown fuse by visual inspection so check it with a multimeter for continuity across the terminals.
Replace the blown fuse. Go to your local hardware store and pick up a matching fuse. Make sure you check the model numbers of the fuse as well to be sure you get the right component. Install the new fuse and put everything back together.
Check the continuity of the circuit if you continue to have power problems. If you have a problem with continuity in the circuit, then you may have a bigger problem than just a blown fuse. Sometimes a power surge will fry a GE microwave's circuit board, which you will need to replace.
