Power suply pc error

P4 computer so the range will be damaged, particularly in

power supply because the burden is too heavy to

generate excessive heat causing

damage to power PD TSB. there are a few tricks to

improve the power supply is mainly brand sun. if

computer can not work a flame at all or can only

indicators only and do not want to go in bios or does not exist

display on the monitor could have suspected the power supply

damaged to be more convincing if not nothing wrong

you try your computer with the power supply has a friend

or relatives who are still normal for the computer. and if

Your computer can be ascertained flame power supplynya

dah damaged then please follow the following trick

1. off power supply from its place, then unscrew

power, see what there is visible damage

including capacitors swell, etc. Resistors burned.

2. try to check the fuse broke or not with OMH meter

by measuring scale 1Xomh

3. if the fuse well and there is no try burning tanda2

Avo plug insert (positioned Volt 10) - the cable

dasn + black color green color cable there around 4 v TEG

What ill. if not we check the initial supply

4. diode checks that brigde four diodes are leaky or not.

5. check gate for power swiching whose value is 2 R

1 MOhm diparalel

6.jika we give gate at TR TRS TSB Avo menujuk 4

volts then it can be ascertained have been damaged and with R

replace our work will be completed.

7. now try short of the green cable with Kabil

can rotate the black fan or not, if not

Now we turn to another gate you try to move

avo plugs - to cable and + yellow color to color

green. let a few moments and try again shortkan

cable with the color green color hitam.kalau fan could dah

normal rotates power supply is likely

not mean there is something wrong if ic tr or damaged then

you should check it carefully for

Computer Power Supply Modification

Given the current high price of travo, so to save costs, there is no harm we use this trick to fulfill our will kebutuhun power supply. In addition to the cheap trick can also produce large ampere power supply for us. This trick is very useful for colleagues who are hobby ngebrik (istilanya) both in the 2 meter or on FM. We all know that the plane was membutukan kosumsi transmitter power supply with a large current. Hopefully this trick bermaanfaat for us all.
First we butukan is Supplynya computer power that has been unused. We can buy flea ditukang (rosokan). the most cost about 10 thousand. Please note that the Power Supply current computer is a large discharge voltage of 5 Voltnya. While the 12-volt current is rather small exit. While we need is a voltage 12 Volt. For that we need to modify in the following manner:

Search rasistor on pin number 1 IC LM 494 leading to the 5 Volt output tegangang rasistor replace with the value 18 to 22 K, connect with the 12 volt output.
Replace the R pin number 4 of IC LM 494 is to ground with 47 Ohm R
Diodes with the symbol -> <- located belt replace with 12 volt output diodes associated with a 5 volt output. Since this determines the size of the ampere.
Replace the coils on the ring with wire rod Ferrite large email.
The latter, usually disposable twin transistors replaced by C 2625 D4242
For his on swit jamper green wire with black cable.

After that modification process is complete, we stayed test results. The way most young people is by shorting the poles - the poles + on 20 ampere fuse. if you can break means the modification work and ready for use. We just attach accessories that we are good at power supply so that seems cool.
