I had my MD30112 PSU blow up recently. I shipped it to Ohm Supplies and they fixed it and shipped it back to me for just over £50. I think they sell a repair kit too.

Fault code 3F? Westinghouse smart drive LT819S


i found this answer in another place


The F3 is as follows,

F3= Motor Sensing Fault.

Either the motor is faulty, or the sensor attached to the middle of the motor is faulty.

You can check the windings on the motor for correct resistances at the wiring connections on the harness plug.

Pins 1/2 should be 32 OHMS,
Pins 2/3 should be 32 OHMS,
Pins 1/3 should be 42/44 OHMS,

Any other readings apart from that means the motor is stuffed.

To remove it, undo the motor wiring connecter, undo the 2 bolts (1 on either side) of the motor and lift the motor away from the base of the machine. Also, you may have to undo the motor sensor wiring connecter also*

If the readings check out, then you need to replace the motor sensor which is attached to the very middle of the motor, visible from underneath looking up at the motor.

Green and black pins are short but smps is not working


Have a look at this
http://en.wikipedia.org/wiki/ATX_PSU#Power_supply
article which tells you what your PSU connections should look like.
You are right in supposing that connecting the green wire (pin 16 in the article) to any of the black wires will turn your PSU on - a straightened paper clip is often suggested for this purpose. Some manufacturers, notably Dell in their earlier computers adopted a non-standard pin-out for their PSUs (I don't know what colour the wires are for that case. To read about Dell pin-outs see the link at the bottom of this
http://wiki.xtronics.com/index.php/ATX_Pinout
webpage).

If you are unsure you might try a PSU tester (eg see this
http://www.amazon.com/s/ref=nb_sb_ss_c_0_10?url=search-alias%3Dcomputers&field-keywords=psu%20tester&sprefix=psu+tester%2Caps%2C667 Amazon webpage for plenty of examples). This may give you a better idea.

Of course it is more than likely that your PSU is defective. Try a spare PSU of the correct spec. in your computer.

I would like to know how to troubleshoot a brand new Ultra LS600 power supply. I would like to go beyond hearing "it's dead" since I am getting power to the motherboard (via indicator light)m but the PSU...


You can start the PSU manually with a paper clip.
Remove the 20 pin connector from the motherboard, leave the four pin power connectors attached to your various drives (this will provide a load on the power supply when it start up (provided it is not faulty).
Look at the 20 pin connector with the connector facing you.and the locking clip to your left.
The fourth pin from the bottom LH corner should be a green colour wire and the next two wires (5th & 6th pin) should be black and next to the locking clip.
Straighten a paper clip and insert it into the 4th pin and into the 5th or 6th pin (ie connect these wires together). These wires connect to the front panel switch to turn on your computer. You are testing the power supply only and since it is not connected to the motherboard the computer won't start.
Now connect the power unit to the mains and switch on the mains, if the power supply is OK the PSU fan should spin up and your hard disk should also spin up. If nothing happens the the PSU is faulty.
You can test the +5volts and +12volts supply on a 4 pin power connector with a multimeter. The red wire is +5volts and the yellow wire is +12volts and the black wires are negative (ground). The voltage readings should be within 5% of these voltages.
There are other voltages to be checked +3volts, -5volts, & -12volts. but these are not as critical.

LOGIK LCXW32HD1 TV TV had total failure took for repair told that the power supply was us and that parts are no longer available


I have had 3 of these sets, all with blown '+5V Standby' circuits. The culprit was the 8-pin DIL FSD200 controller chip. When it blows it takes out the little optocoupler, the small SM bridge rectifier (PCB underside) and the 20mm fuse. The FSD200 is hard to source, but Digi-Key have plenty at £0.88 each. They also sell replacement bridges, fuses and optocouplers. If you attempt the repair I recommend that you fit sockets for the controller and optocoupler. If you fit the opto round the wrong way the +5V Standby rail will try to rise to over 10V and the set's control logic may be damaged. Good luck.

Replacing CRT neck socket after arcing problem.


Hi.

Don't know what happened to the last post I sent you its disappeared.

What I think you should do is definately replace the CRT white socket (tube base plug).
You can either take the CRT number from the label on the tube & put it in to google then search for Crt base plug.
Or see if there is A repair shop local to you who can order the tube base for you.
Are you definately sure the arcing is external to tube & not happening in the tube neck ?
Is the CRT made by LG / PHILIPS. These are notorius for for arcing over internally I must write at least 1 A week off for this problem.

If you can still run the set try tapping the neck of tube with screwdriver handle if pic flashes or goes predominately1 colour you are looking at the tube with internal short.

If this is the case there are ways of trying to get rid of the internal short let me know what you find ?

Arcing between pins on CRT


Hi.

Your problem is due to moisture in the the Crt base socket you will need to replace the white plastic crt plug I have tried to clean & dry them out but it never fully corrects problem.

As far as the pins & glass crt neck goes clean them with Isopropyl alcohol this will thoroughly clean all the carbon off.
