Sylvania SRCD 820 4 in 1 unit powers up, cd diplay blinks (as if searching), but no power to the cd drive unit, hence, sled will not move and disc will not spin. Is there a fuse for the cd mechanism?

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here.

Samsung printer 110v plug to 220v

You would have damaged the power supply section but in many cases the front end contains a surge protector with a variator which will short and blow the fuse. So check fuse replace and check for short in the input circuit of the power supply, if the Switch mode is damaged then you need to replace the unit with a 220 volt type or if only the 110 type is available then use a step down transformer to down the mains to 110V with about 0.5Amps

My Bose radio stopped working, no sound no lights AWRCC1

Hello
Check its power cord first. If it is OK, check its power supply section inside. There will be a fuse at the power supply rectifer board. Check it. If it is found opened [damaged] never put an other fuse, without proper check to the power supply and main audio amplifier section. There must be some reason for the blow up of this fuse. Without rectifying the fault, replacing an other fuse, may make more components to get damaged, and the repair work may cost more. OK.

Emerson mod. ewc 1301 keep blowing fuse

Hello
There must be a direct short in its power regulator section. Normally a shorted switching output transistor at power regulator section will cause this fault. You have to check all the components in the power supply switching retulator section, including rectifier diodes, zener diodes, electrolytic capacitors, small signal switching transistors etc. In fact, you have to check the components in the entire power regulator system. Never put any more fuse into it as an experiment; this will make more components to get damaged. Check the sets' circuit well. OK.

My power plug had electric shock while i was watch tv now my tv doest work

Hi,
Your unit has fuse protection for AC supply malfunction like the short circuit. You must take it apart and check this fuse, for sure it is already blown. Pull-out it in the board and replaced it with same current (ampere) and voltage ratings.
Replace also your power cord to ensure that same cenario will not happen again.
Visit your local electronics supply for the replacement, this parts are widely available at the market.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

I am using philips g 370 trimmer , i got this from USA, when i have kept for charging ,light is not getting displyed on the adaptor. is there any other way that i should go

Make sure that the voltage of the unit is according to the device as if you have plugged in a 120volt unit into a 220 volt supply the adapter or the power supply would be damaged.
So please check this out , if not check the power supply section of the adaptor for failure of fuse or powerr components.

Fuse problem

Why it always blew, then you have a short circuit. It is not your fuse is the real problem because it is a guard to your unit. Once there was a short circuit it will blew to avoid further damaged to some parts.
It is commonly due to a shorted parts on the power supply section. You must isolate the shorted parts to back your unit to normal.
If you are not a technician then you must look for a qualified one to trace the shorted parts. This will fix your problem.
Thanks for using fixya.

Keeps blowing the fuse inside the unit.

When a fuse blows suspect an overload in either the power supply or main amp stage. The most likely cause is some part acting like a piece of wire instead of doing it's job. In the power supply it could be the transformer, voltage regulator, or the rectifier or any diode. In the amp section any semi-conductor on the heat sink.
Check first for burnt or damaged parts. If you have a multimeter any transistor or diode will quickly show up. For when you have the meter on the ohms setting and touch the terminals with the probes, it will show as if you had touched the probes together.

Behringer super x pro.the fuse keeps blowing on the ac inlet(t200 MA).a replacement unit works fine in the system.

When a fuse keeps blowing suspect an overload in either the power supply section or main amp part.
Look for burnt or damaged parts first.
The suspects in the power section are: transformer, diodes, rectifier, voltage stablizer, regulator.
In the Amp Section anything on the heat sink.

110 Volts plugged in 220

More than likely just the power supply would be damaged, it should blow before the rest of the unit gets damaged. Maybe even just the fuse inside where the power lead connects is blown.
