SOURCE: Replacement External Power Supply

So the old power supply doesn't have the output voltage, current and polarity noted on the label? What a ripoff! *grin* Did you look on the case near where it plugs into the monitor? Sometimes that will tell you the voltasge and polarity. Poliarity? Get that one wrong and the monitor could be cooked instantly! But it's usually positive. I found a completed eBay listing that had this info: "the power supply which the seller used to power up this Planar Flat Panel is inventoried as follows: ViewSonic 12V Power Adaptor Model # SYS1126-5012" I looked that one up, and it's listed as 12V at 4.17A. PC Hub has them for $28.62: http://www.pchub.com/uph/laptop/345-19804-2285/AC_Power_Adapter_5V-12V_Others_SYS1126-5012.html Good luck!

SOURCE: Horizontal output transistor keeps failing

The horizontal output transitor is always connected to the primary winding of the flyback transformer (via collector) and also to the horizontal deflection coil via an electrolytic capacitor. The most likely suspect for damaging the transistor is the fylback transformer. In some countries there are electronic stores that test flyback transformer by winding a few turns on the ferrite core and applying a test voltage. This test will only test the secondary. The primary winding is difficult to test for turn to turn short because the resistance is quite low and you do not know the 'good' resistance.

SOURCE: PIONEER DC-Z92 CASSETTE DECK AMPLIFIER

Is this one of the units that has a ribbon cable ( looks alot like an IDE hard drive cable) that connects all the components together? It also has a squre plastic fan that protrudes slightly from the rear (by about a 16th of an inch)? If so, it's the power module which consists of 2 boards (along the fan housing). You can probably find replacements for about $70, but I wouldn't bother. They quit making new replacements several years ago and any board you get now is just a pull from old stck units.... and they fail about 2 minutes after you put them in. Pioneer knows this but still sells the defective parts.

SOURCE: no output from power supply

Hi,

I am assuming that you are very familiar with electronic circuitry and components, use of a DVM and a soldering iron. In the absence of a schematic diagram, and since you have perform initial voltage checks, perhaps you can wing it. Your "brick" will have to follow the basic design of an SMPS (switch mode power supply). Simply stated,an SMPS is an AC to DC to high freq AC then to lo V DC converter. Per your post, you have checked that there is DC (B+) from the AC mains, then what is needed is to check if there is oscillation to produce the high freq AC. Often design calls for an optical coupler, a small rectangular looking component with four pins, two at each end. This is nothing more than a LED and a Light Dependent transistor. Its function is to switch/trigger on the oscillation (and therefore start the SMPS producing the lo B+s).

Again, since there is no readily available schematic diagram, might I suggest that you post back the part numbers of the ICs and transistors. What we can do is pull out their spec/data sheets and/or application diagrams. Such would give us a general idea of the working voltages at what pins and what each component is supposed to do. Example, let us say your power supply uses a 817A/0635 opti coupler and/or an SG5841DZ controller IC, then we can search for them as initially described.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Dear Guru my power supply of my computer with model enp-2120d doesnt work no power output so please gave me some idea or schematic diagram,thank you.


Do not try to fix this power supply. Better to replace with new or good used. I see many on ebay from 13.50 to 25.00. Also google that model for other options. Most likely fuse on the power supply has failed but if you bypass the fuse, with jumper wire or another fuse, will blow again. Probably capacitors. Good luck

The only thing to do at this point is to replace the Power Supply with a KNOWN to be good, compatible unit, and see if the rest of the computer hardware components are okay.

Going by your information stated that the Power Supply is an Enhance ENP-2224B SMPS, (Switched-Mode Power Supply), it is a special shape.

If it wasn't for the Slim Micro-ATX computer case you have, you could use an easy to obtain ATX form factor Power Supply.

From a quick search though it looks like a replacement unit is affordable,

There is simply no way to tell if the motherboard, and/or Processor, and/or Ram Memory, and/or Harddrive, etc., is okay without having power.
Unless you transfer the components on the motherboard to another working motherboard.

[NOTE*
If your Power Supply has a rocker switch on the back that lets you use 120 volts, or 220 volts, make SURE it is set to the right voltage.

USA?
120 Volts
Europe?
220 Volts
Australia?
220 Volts
Japan?
100 Volts ]

Where to purchase a new 250w ENP-3125 power supply unit in the uk


Go to any computer-store, carrying your old power-supply with you,
tagging which of the connectors that you use, and which of the connectors that you do NOT use. The sales-representative can then find a "generic" power-supply with the same height/width/depth, and with the necessary connectors,
and with the necessary power-output (volts & amperes).

kerrimcshane, Problem with mutiple DC voltage output of unit's "switch-mode-power-supply" inside your unit. You will need to do lots of reading of the extensive failure complaints already documented on this and similar models of this brand to understand problem with your unit. There is plenty of documented "history" already out there!! Have you already tried YOUTUBE? It could be a possibility that it has failed electrolytic filter capacitors on the power supply printed circuit board that will need to be replaced by a qualified electronics technician. Just do some research on fixya and the web first before you do anything else!!!! 12fixlouie

I need a replacemant power supply for my printer. Where can I get one?


HP doesn't have a replacement power supply available, and to my knowledge there is no replacement power supply available.
The power supply itself would have to be rebuilt.

More than likely if it's the power supply, and not the fuse in the power supply area, (Behind the plate with the two Number 10 Torx screws. BE SURE, the printer is unplugged from power!), it's an Electrolytic Capacitor, or two that have gone bad.

Electrolytic Capacitors are Filters used in a power supply.
In the Input stage of the power supply, they filter the incoming AC electricity, before it reaches the rectifier.
In the Output stage of the power supply, they filter the rectified DC electricity into true DC electricity.

Look to see if you have any bulging, or leaking 'Caps'. You have to use the same voltage, but you can go slightly higher with the Microfarad's. (mf)

Example: I replaced two 16 volt, 330mf 'caps' with two 16 volt, 430mf 'caps'.
('Caps' = Electrolytic Capacitors)

More info to help identify bad 'Caps'.

I unplugged it and now it wont turn on after I plugged it back in to the wall outlet


The exact same thing happened to mine several days ago. I opened mine up, noted that two of the capacitors on the power supply are a bit puffed up, and tested the power supply's 12V and 5V outputs. The 12 Volt output is fine, but the 5 Volt output is only putting out 2 Volts. In short, all of the capacitors on the power supply are made by the same company (Jenpo) and apparently these capacitors were made using the stolen but incomplete formula for manufacturing capacitors much more cheaply. That "capacitor scandal" has cost electronics manufacturers millions. In any event, this would explain why Walmart blew out these Cyberhome CH-DVD 300 players for such a cheap price. Obviously all of the capacitors on the power supply will eventually fail. I have already experienced similar capacitor related problems with a few computer motherboards and other electronics equipment which I bought in the early to mid 2000's. I am contacting Cyberhome to see if they will send me a replacement power supply to go in my CH-DVD 300.
