I don't have the transformer for the power what

Use an extension cord to plug the transformer into a different "test" GFCI receptacle, if it holds on the test GFCI you know that the GFCI for the transformer needs replaced. If it doesn't hold, then the transformer is on the way out and should be replaced. Sometimes motors and transformers will "leak" current and still work, but not trip a regular circuit breaker. A GFCI that is doing it's job will catch it though. Don't force a GFCI like that...you can wear it out prematurely.

The subwoofer for that system also powers the rest of the speakers as well as the
subwoofer as you probably know. Is there any power light coming on? Like on the subwoofer itself where ever the power light is. If not check for a fuse. If no fuse is visable you'll have to take the subwoofer apart, the plate amplifire. There will be screws all around the metal part on the back, you must remove all the screws holding it together. Most of these types of systems have the fuse inside on the board. Also sometimes the fuse does'nt look like a fuse, it could look like a resistor or a ceramic style disk capacitor. Yours will probably have a glass type fuse. If you don't see one look on the board next to the components on the power supply board or if all together look near the transformer area for a F meaning a fuse. /there will be letters and numbers next to each component eg., resistor, capacitor, diode, etc. If you find a glass type fuse replace it with the exact same rating which will be on the end of the fuse on the silver ends of the fuse. If it's not blown you'll need to test to see if your getting voltge out of the transformer. You'll have to have the DVD unit hooked up to it, you don't have to have any speakers connected. The cable from the DVD unit to the subwoofer is what tells the amplifire on the subwoofer to turn on. You could have a blown amplifire IC. I don't know what type of ouput amplifires this uses but I'm thinking IC and not seperate transistors for the output amplifires. You might have one of those blown and if you do then the whole system wont work. Hopefully if that is the problem you'll see a burnt mark on the IIC itsel or some type of burnt spot on the board somewhere to lead you in the right direction to the problem. It could be as simple as a power supply capacitor, who knows til you get into it and start looking around and testing some things. If you don't have the knowledge to do this I am the cheapest electronics business in the USA. It's not a bad system, CrutchField sales it. Also I can waalk you through the steps to narrow the problem down. I help people everyday. You can contact me at [email protected]. I can then give you some more info and my business phone number if you feel up to doing this. It's really no big deal and I find that most of my customers who have never done something like this love and learn some electronics and now fix some other stuff they had laying around. I'm here to help. Thank you for contacting me, have a good day.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/mark_b53a7494531bf96d

Simple answer; no.I don't know where you are but step-down transformers are a pretty common item (some are even reversible) but make sure that the transformer's power rating is adequate for the blender; for example: if the blender is rated at 200 watts or 1.8 amps (roughly the same at 110V) use a transformer rated at least 50% higher to avoid having the output 'sag' under load.

1. To test a transformer you need to know what type of transformer it is first. There is a step up transformer which steps the voltage up and a step down transformer which steps the voltage down.
   
2. You will still test the transformers the same way for step up and step down transformers. If it is a step up transformer apply the incoming power to the transformer or plug it up. Now take your multimeter and place it on the AC volt scale and test the voltage if the voltage on the data plate says the transformer should step up to 220 volts and it doesn't then your transformer is bad.
   
3. Now repeat the same steps for a step down transformer. Plug up the incoming or primary power and test voltage on the outcoming or secondary side the voltage should step down to the proper value. If you don't read any voltage on the secondary or outgoing side then the transformer is bad.
   
4. To read the voltage place the two meter leads on the secondary side, or the side you will plug your equipment into. If the secondary side is an outlet then place the two meter leads into the top two slots in the plug and read voltage. You also want to make sure the incoming power is working as well. Otherwise you will be reading a bad reading every time.
   

First, check the 220v line and breakers are properly grounded and that you are getting a constant 220v at the plug. Then you will need to check the transformer on the unit.To test a transformer you need to know what type of transformer it is first.

If all that looks good, then you will need to replace the control board. Here is a link to the parts for your range.

The you most likely have one of two things for fuses places, (1) on the motherboard at the power connectors, or (2) there could be multiple fuses (ie. one in the battery, one in the power adapter, and maybe one on the motherboard.) the latter is rare but I've seen it. It doesn't really matter though because any fuses are most likely soldered in and you'll need special tools to change them without causing more harm then good.

However, if your computer is having a problem where it just plain won't turn on (ie. hit the power button and nothing happens at all), with laptops, you could need a new computer.

I don't know any site selling power pack gears.
Maybe ebay has gears or sells used power pack.

Easiest thing might be buy cheap plug-in timer, set power pack to override, and plug power pack into cheap timer.

Intermatic does not sell the timer module separately, or the gears.

The LEAST expensive thing to do is to buy an external stepdown transformer.
Here is a link:

http://www.world-import.com/transformers.htm

The 100 Watt would be adequate... If you think you might need more you could have a reserve for other equipment... At around $8 USD I don't think you can beat that. The labor cost to change the internal transformer would cost many times what the external transformer costs, not to mention the cost on a new internal transformer.

Your Gibson is sensitive to magnetic fields You need to keep the guitar about 10 feet away from the amp as the power transformer is radiating magnetic fields that is causing the hum. Solutions: there aree several... most are NOT practical... such as encasing the transformer of the amp in Mu-Metal shielding. Changing the transformer to a toroid type (they should deliver them that way) encase the amp in a thick steel cabinet... all this is ridiculous... putting distance between teh amp and the guitar is probably the only practical solution. The level given any particular orientation should fall off with the square of the distance. Note that OTHER stage equipment also will have transformers that radiate. Much of the new amps do NOT have power transformers that run at low frequency so they don't have this problem. Marshal is old school and they use the older power supply designs that radiate the magnetics.

Check the part number on the transformer: the link at the bottom may help it if it is listed there..The transformer that i had. PN: E190246 Mfr: HF-4822L2TN (single in/output) (ie... two wires in and two wires out)
(Hang Fung Eletronic Ltd.) has a 42.2 vpk >15watts
(power supply for an Emerson 4 in one Entertainment system
(record, CD, cassett, radio)
Emerson Model: NR305TT 19watt
