I have a panasonic RX-ES29. The 2 pin power connector is faulty as you have to hold it hard to one side to get a connection. I want to get inside the case to take a look. I have taken out all the screws I can see but it won't readily split apart? Thanks for any help on how to split the casing apart. Regards Terry

Hi sjcrofts,
The most common problem for most people is knowing what wire color is positive & which wire color is negative. The colors blue, red, green, light blue, light red & light green are normally positive. The color white & black are negative. Your board uses only 2-pin connectors. The 3-pin power connector can be turned into a 2-pin connector to work with the M848ALU pins.
(Page 13, PANEL1). How to? Take the three pin connector, on the back side of the connector you'll see a small tab that holds the wire into the connector. Use a needle & pull tab up while pulling the wire out at the same time. The wire should slide out. Insert the wire back into the connector next to the other wire. You do not need to hook up the SUS led which stands for suspend.

dff74fa.jpg

Pin 1 is positive & the manual shows this by adding the _P = positive.
Pin 3 which is to the right of pin 1, is negative for the hard drive led. Pins 9 & 10 are not used.

Good luck sjcrofts!
Mike

I'm having problems with my aprilia rx50 (2008), it ticks over but when I knock it into first and slowly release the clutch it pulls about a metre then the engine loses power and cuts out ! Any ideas


Hi Anonymous, the following applies to carbureted also fuel injected models and the usual suspects are:
1. Severely discharged or damaged battery, 9 volts or lower.
2. Faulty alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.
4. Faulty main circuit breaker or ignition switch, check for loose connections and continuity.
5. Faulty system and or ignition relay, check for continuity.
6. Faulty ignition coil, ignition/electronic module.
7. Faulty CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Water or dirt in the fuel system, carburetor or filter.
9. . Restricted, blocked or kinked fuel line.
10. Fuel tank empty.
11. Gas cap is not venting properly or fuel tank venting system blocked.
12. A faulty fuel pump, pressure regulator and or fuel injectors.

One bad lead can cause a computer to fail to detect a hard drive continue on a cycle or to shutdown

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA and

the leads from your motherboard to your hard drive make sure they have a secure connection and are not faulty or just replace them there probably old and faulty

I have several computers at home, and none og them can recognize this portable device. Hitachi 250 GB Mod: SDM/250RW


1) Power:

It may be the problem that occurs with a lot of USB powered devices jrherrer. Not enough power provided.

The USB cable plugged into the computer, provides signal wires for transferring information back, and forth, and also provides 5 Volts DC for power. (Two D cell flashlight batteries produce 3 Volts DC)

http://en.wikipedia.org/wiki/USB

[ Below shows the Signal pins, and the Voltage pins of the USB B Mini style connector, (Male), used to connect to the SimpleDrive Mini external harddrive,

Pin 1 is for the 5 Volts DC Positive (Wire color - Red)
Pin 2 is for the D- Signal (Wire color - White)
Pin 3 is for the D+ Signal (Wire color - Green)
Pin 4 is not connected. (Or sometimes joined to Pin 5 with a Resistor)
Pin 5 is for the Ground (Wire color - Black)

Just added info in case you wanted to know ]

From what I see the SDM/250RW has a USB port on the side, and a DC Power Jack, used for an AC adapter, also.
(Round port with a pin in the center)

http://www.hitachigst.com/tech/techlib.nsf/techdocs/0C876B7AB91B23988825773F006BEA02/$file/SD_Mini_DS_final.pdf


From what I see stated from Hitachi, and sellers on the 'net, the AC adapter may not be provided.
Many of those who provide a review state that both the USB cable, and the AC adapter is needed to provide enough power. Seems to be a power hungry external harddrive

It's a 2.5 Hitachi SATA laptop harddrive inside that external case. (The Harddrive is 2 and a half inches across in Width. Common size used for laptops)

When using an external device powered by a USB cable there are general guidelines to follow,
A) The USB cable should not be more than 2 feet in length
B) Connect the device directly to your computer, instead of through a hub, or other device, unless the USB hub has it's own power.


2) USB cable:

Could be a faulty USB cable, although I imagine you have tried different ones by now.


3) Interface Circuit Board:

The Hitachi SATA 2.5 harddrive inside the SImpleDrive Mini SDM/250RW, plugs into a small circuit board located inside that external case.

Components on the circuit board may be fried, or the Harddrive may have come loose from the interface.

Loose from the interface
To explain;
The back of the harddrive has connector pins sticking out.
The interface has socket holes which the pins insert into.

Faulty circuit board
The external case of the SimpleDrive Mini SDM/250RW can be carefully opened up, and the Hitachi SATA 2.5 harddrive extracted out.

Another inexpensive external case for a 2.5 SATA harddrive can be procured, and the Hitachi harddrive put in it.

Example of a 2.5 SATA external enclosure,

A friend unplugged all wires frm inside the compaq i need instructions on how to reconect it so it wrks again


First check your hard drive fixed with screws in cabinet. Then if it(your hard drive) is a parallel it must have 4 pins for power and around 40 pin on its back. Just find a four pin connector that will coming out from pc power supply or smps. Just connect it to your drive for power and find 40 pin connector that is also connected to motherboard on its other side insert that plug in hard drive carefully. Don't use force to connect it because it can bend or break pins of hard drive.
Or
If you have sata hard drive its also have slim face power jack comes from power supply or smps. Its other cable is small faced some time red or some time black in colour connected on motherboard on one side and just take it other side and connect it on hard drive.
For future never try play with your pc like this because it can cause hardware problem in your pc.

How do take out the PSU? I have already removed the exterior of the computer but I cannot figure out how to remove the PSU connections to the other parts of the computer.


very easy. 4 screws hold supply on on each side of the PSU. Firmly grasp the connector (24 or 20 pin ) from the Motherboard. Now remove the 4 pin ( 2 yellow 2 black) connector from the board ( may be keyed as other NB connector. Remove the power connectors from CDROM, Floppy, Hard Disk and anything else with connectors. You should now remove the supply.

Firewire 4 pin connection is npt reliable with my firestore fs 100. Can I fix this myself?


Hello there!! I think that you mean that the firewire connections is faulty with alot of errors during rec.This is caused by many movements in the cable and so the connector after a while gets loosen. I mean the 4 pins inside it. Therefore you should replace the 4p connector .You need to have experience in replacing connectors like this,not so easy though. Another solution for this kind of problem is to put some kind of glue around it so when it gets solid no more movements will happen again, but this is not the real solution.

Jumper pin settings


Hold the samsung SP1203N hard drive in your left hand with the lable facing upwards (then power cable connectors will be on your right hand side and the IDE cable connector will be on your left ahnd side). There are two raws of jumper pins in between the above two connectors

Master - join the first two column of pins on the left with a vertical jumper
Slave - leave all pins free (without jumpers)
Cable Select - join the third column of pins from the left with a vertical jumper

job done !!

E machine wont start


Here's something you can try: If you can borrow a computer power supply rated at 350 Watts or more from someone, do the following: Unplug your power supply from the motherboard. If it's an older model (pre-Pentium 4), there will be one wide (20-pin) white plastic connector. Along one of the long sides of the connector, there's a retaining latch. Squeeze it, and gently rock the connector from side to side along its length, while pulling up. The connector should come free. If it's a newer PC, there will be a second connector with 4 pins, and yellow and black wires. If so, squeeze its latch and just pull up on it. Next, disconnect the white power connectors from the optical drives, hard drive, and floppy drive. If the internal fan you talk about is a case fan, unplug it, too. At this point, you should be able to take all of the power cables and hold them out of the case.

Now, plug the power cables from the power supply you borrowed into all of the sockets you just vacated. The motherboard connection(s) have a little nub on one side; this lines up with the latch on the plug(s). The hard drive and optical drive connectors only fit one way. The floppy connection is wider on one long edge; this sits on a little shelf when the connector is plugged in. Plug in the case fan. Make sure the borrowed unit is not resting inside the case. Finally, plug the AC power cord into the socket on the borrowed power supply. You should now be ready to push the PC's power button. Do so.

If the PC boots fine, you have a bad/failing power supply installed in it. Sometimes they just don't have enough power to boot the motherboard when other accessories are also drawing power. If more accessories than those which came with the PC were added, this makes the problem worse.

If this works, you need to replace the original power supply. With your PC turned off and unplugged, remove the 4 screws holding the power supply to the back of the case. Lift the unit out. If you can keep the borrowed one, it's simple. Place it into your casr where you removed the original one (note the unit will fit two ways, but the screw holes only line up with one of them), line up the screw holes, and install/tighten the screws. Plug in the AC cord, and boot the PC up. If everything is okay, turn it off.

Since you're already inside the case, take some canned are and dust off the internals. Be especially sure to remove any dust between the processor's heat sink fins. Hold the processor fan with a finger to keep it from spinning.

Of course, if you CAN'T keep the borrowed unit, disconnect it as above, obtain a replacement, and repeat the installation/connection steps above.

Let me know if this works.
