Power supply Sony PS-LX10

I am connecting tis to a non Sony product. There are 2 plugs in the back one is a 3 pin but looking inside only one red and one white are connected. Is this a 12 V supply? I tried but did not get it working. The other is a 5 pin plug marked "System control" I assumed this was only for using it with a Sony product but do I need to connect this too? There are also 2 ordinary phono plugs wich will be connected to the amp/phono. So how do I connect?

Connect the RCA phono plug wires usually red and white wires with plugs to a receiver or amplifier in the back of it to phono in. New receivers will not work unless you have a phono preamp. Best to buy a vintage stereo receiver or amplifier with the correct connections. Make sure you connect the ground wire which is usually a small black wire coming from the turntable to an receiver or amplifier. Turn the stereo receiver on phono. Connect it to any screw attached to metal on back or look for a ground screw. If you do not attach it it will hum.

Hello, I have a similar turntable Sony PS-LX10, I found the service manual of Sony LBT-V10 what include PS-LX10 turntable and I solve the problem with power supply. It need 2x12VAC to be connected at pins 1,2 and 3 from System Control conector. I bought a transformer with 2x12VAC output and minimum 5W, a power switch ON/OFF and a power supply cable. I install the transformer in designed place in the left side of turntable and the power switch instead the big connector (system control). So the turntable received power and some LEDs (thouse from speed) lit, but the turntable do not work due to missing the signal control from main Sony system LBT-V10.

Pin out for a dell PS-5201-8D2 power supply


Use caution, some older Dell machines used a non standard, proprietary pin-out on the 20 pin connector ALso the 6 pin is suspect. If you connect a regular ATX PSU, you will fry the MoBo. Look here

I have a sony ps-lx10 turntable, and want to connect it to a non-Sony system. The power ribbon needs to be modified. How do I do that?


First of all you would need to know 2 things. One the voltage supply needed to run the turntable. Two the voltage outputed by the non Sony system. If these don't match you could have a problem. For example if the Sony Turntable runs of say a 6 volt supply and the system puts out say 12 volts. You will damage the turntable. Chances are unless the non Sony system was actual made by Sony under a different name then the two supplys will not match. If you can connect up the two the Turntable will either run slow or fast. If the output supply is only 6 volts and the turntable motor works on 9 volts or higher you will never get it to run at the correct speed.
If you work out the two work off a similar voltage, you need only connect the plus wires together and the negative wires together and the motor should turn. Most turntables have speed presets, for each speed. You will need to find them and adjust them to get the speed right on each speed.

I have tried running 2 different M4A79 deluxe motherboards with a corsair 650W power supply, phenom I X4 processor, and an nVidia 9800GT video card but neither of them will so much as turn on with...


It sounds like the ATX power supply is not getting turned on by the motherboard.
In order for this to happen, pin 14 (PS_ON*) of the 20-pin ATX power plug from the power supply must be pulled to ground. You can test this by plugging the power supply in to AC power without it plugged in to the motherboard.

Using a paper clip, short pin 14 (PS_ON*) to pin 15 (ground) and the power supply should turn ON.

Looking at the front of the 20-pin plug, with the latch on the top, pin 14 is the 4th from the left

If you can turn on the power supply by shorting pin 14 to ground, but it doesn't happen when plugged into the motherboard, there is most likely a jumper setting on the motherboard which has not been configured correctly.

I hope this helps!

Hi, I have an LG42" LCD tv and the red light will


IT sounds like the power supply, yes with a digit meter and some basic knowledge of electronics, you can check and see if you have 110-120v ac coming in to tv and check on board to see if you have low voltage DC going from power supply to main board. You will need a schematic of this set to check proper voltage, but to make sure the PS is putting out then just check from pin to pin if all voltages are low and non 12 or 24 then PS suspect.

When I opened my playstation 3 it doesn't turn on.no signs of power


Im presuming it didnt turn back on after you had put it ack together? If so open the PS3 back up again and check 3 things :-

1. There is a two wire connector at the back of the power supply, make sure this is plugged in
2. There is also a five wire connector at the front of the power supply that plugs into the motherboard. Also make sure this is connected.
3. The power supply sits on two upright brass pins, make sure it is fully sat down on these pins by applying light pressure to the top left hand side of the power supply.

Hope this helps

Faulty power supply or MOtherboard?


Test the Power Supply first.

If you have a multimeter, use the Positive (Red) probe lead to connect to the power wire to be checked.
The Negative (Black) lead connects to ANY ground wire. (ALL Black wires are Ground wires)

Three main voltages are produced by a personal computer Power Supply.
1) Orange insulated wires are 3.3 Volt
2) Red wires are 5 Volt
3) Yellow wires are 12 Volt.
(Again, ANY Black wire is a Ground wire)

Or use an economical power supply tester.
One example,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=5250576&CatId=5471

You are making a connection from the green Soft Power On wire, to any Ground (Black) wire with that jumper wire.

Using an HP Pavilion A1330E desktop computer for an example,
we can see that the main power cable is a 24-pin ATX main power cable.

This is readily shown by looking at the motherboard,

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00496280&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&lang=en&product=1829044

Scroll down to the motherboard illustration, and the motherboard photo underneath the illustration.

This is the pin-out for a 24-pin ATX main power cable, and connector,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

The Green wire (Pin 16) is the Soft Power On wire. The other end of the jumper can touch ANY Black ground wire.

1) ALL the lights use less than 1 Watt of power.
2) EACH fan uses 2 to 3 Watts.
3) A typical Processor can use anywhere from 51 to 125 Watts. Depends on what Processor it is.

The three Processor options for the Pavilion A1330E are, (Socket 939 style),

A) AMD Athlon 64 X2 4800+
B) AMD Athlon 64 4000+
C) AMD Sempron 3200+

The Sempron 3200+ can use up to 62 Watts
Athlon 64 X2 4800+, 110 watts, and Athlon 64 4000+ can use up to 89 Watts.

Point?
You have nothing but the motherboard plugged in, and the Power Supply takes a 'nose dive'.
Power LED turns off.

Bad Electrolytic Capacitors in the Power Supply.
Replace power supply.

What causes this?
1) Most computer failure can be attributed to the inside of the computer is dirty, as well as the Power Supply.

When the cooling components of the Power Supply, (Fan, and internal Heatsinks), are clogged, the cooling capacity drops tremendously.

Heat = Wasted Energy

The Power Supply tries to keep up with the call for power, and eventually components inside the Power Supply fail.

A can of compressed air for computers, used on a regular basis as needed could prevent this. (Observe Anti-Static precautions Before placing hands inside computer)

2) Cheap quality power supply.
Saves the computer manufacturer money.

Sony grand wega KDF55WF655 6 red blinks


you can try these steps if this doesn't work I suggest replacing IC8002 on the power supply
Low HV Shutdown:
On the D Board.
Check IC8004/pin 7 should be 7.4v.
Check IC8006/pin 2 should be 2.5v if lower will trigger shutdown by causing pin 1 to turn on.
Check IC8006/pin 3 reference voltage 2.2v.
IC8006/pin 1 normally at 0v. If high turns D5007 ON which turns the latch circuit Q6532,
Q6530, and Q6527 ON and turns the AC relay RY6501 OFF.

NOTE: 6 blinks also can be Low B+ protection.

Unregulated 7.5 v from the power supply to 5v reg IC504 on the A Board. 5v to M Board Q2314
to CPU IC2300/pin 43. If 5v missing set will shutdown with 6 blinks

PS/2 power supply connection


You seem to have an oddball monitor if what you describe is correct. The power supply to a monitor[Display Screen is that what you mean?] is either direct to main power- in which case the power cord is either built in with a power plug for wall socket, or has a socket on the back for a separate main power cord. Or is powered from a low voltage converter that delivers low volts usually via a coaxial plug like this illustration PS2 connection does dot come into the equation as far as I know unless you have got hold of something unusual. Tell you what take a shot of the back of the monitor and lets have a look see mean while here's is a shot of a typical low voltage power supply available anywhere.
