Problem identifying P4G533-LA motherboard electronic component

I need help, please. I have a P4G533-LA motherboard that has a burned component that won't let me see the part number clearly. I took a picture and I could only see part of the number. The burned component is located just next to the main power supply socket and is identified as Q34 on the motherboard. The only numbers I'm able to see is: 23 346. I have look in many sites for info including Asus and the only info they supplied is that the component is manufactured by HP. If anyone has this motherboard that can tell me at least the part number of this component, I will be more than grateful... I am sure that replacing the component will solve my problem. Below is a link with a picture. Thanks.

    Hi again !

    I found out that it's a MOSFET from Advanced Power Electronics Corp.,
    but which one? There are 48 pages of MOFSET in the site and I don't
    find any that match the partialy component number that the picture
    shows. Here is the link of the burned MOSFET: http://i40.tinypic.com/2vvuw42.jpg

    and here is the link of the manufacturer:

    Q is a designator for Transistor. At first glance my guess is something else caused this part to burn up. I wouldn't be so sure replacing it will solve your problem. Keep in mind these are multilayer boards and component replacement is not so easy. It also appears there may be trace damage to the board.

Its a diode but where can u find it ? Before replacing this check your powersupply. The parts number will be the same as beside.
Try carefully. You have a small hope.

Hay una placa base Soltek (EQ3402A) (EQ-3402 a) There is a motherboard Soltek (EQ3402A) (eq-3402 a) that is out there. You would need to give more information about what your machine is, which would help identify your control board.

Good Luck

I need to find the motherboard manual for the P4G533-LA


This isn't the full manual but it should help you quite a bit. Apparently, this motherboard is actually an HP board. Click here for the P4G533-LA specs: http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=us&docname=bph07845

Good luck, please post back if you have any difficulties, and thanks for using FixYa.

A friend of mine has the evga 133-p4-nf51-ax motherboard. the computer runs fine and then all of a sudden shuts off. there are 3 capacitore blown on the motherboard. their numbers are c222, c237, c238. i...


The c222, c237, and c238, are motherboard manufacturer identifiers, for Capacitor 222, Capacitor 237, and Capacitor 238.
I don't know either, only the mobo manufacturer does.

BUT, I DO KNOW how you can identify the Microfarads, and voltage for each one of these Electrolytic Capacitors! There are many Electrolytic Capacitor manufacturers for electronic components, but each has their own identifying code. Some are easier than others to read their code.

How to identify Japanese Electrolytic Capacitors,
http://www.hardwaresecrets.com/article/595
[Hardwaresecrets.com]
Page 2 and 3 get more to the direct matter of reading the markings for Japanese Electrolytic Capacitors. Page 4 deals with Chinese and Taiwanese Electrolytic Capacitors.

Also want to include this,
How to Desolder Components;
http://www.hardwaresecrets.com/article/164

From me:
1.I advise using a 40 watt pencil tip soldering iron. use the damp sponge frequently also. Keep the tip clean, and tinned. [I use a soldering station now]

2.I grab the capacitor with my fingers, board turned over, and put slight pulling pressure mostly on one lead. Heat one lead, try to pull up just a little, then heat the other lead. Pull up just a little.
Keep going back, and forth pulling the leads out a little at a time. You don't want to keep the soldering tip there too long, or you'll risk burning the board, so don't try taking the 'Cap' out all at once.

Once the 'Cap' is removed, clean the motherboard area. You want a clean circuit trace area, for that rosin solder to adhere to. I use cotton balls, and Isopropyl Alcohol. Try to find the 91%, (Percent), alcohol. (Walmart)

3.You HAVE to match the voltage! You ->can 'fudge' the capacitance a little. (Microfarad)

Example: If you have a 16v, (16 volt), capacitor that is 330μF, you can use a 16v 430μF in it's place. (μF stands for Microfarad)
(Check Radio Shack, and online)
