How do I wire a Polaris PB4-60 in the USA (115V)?


I am not sure if this will help you out any, but here goes:
Line1 & Line 2 are your Hot Power Wires coming into the motor.
It does not really matter which wire goes to which post of the motor.
This will remain true if you are bringing in 110-115-120 (these are all the same, people just refer to them differently) which also is referred to at times as "Low" voltage, and the same goes for 220-230-240 (again, referred to differently) which is referred to at times as "High" voltage.
Whether bringing in Low voltage or High Voltage, the wires you bring in will number only three:
  • Ground
  • Hot
  • Hot (potentially Hot)
Low Voltage (115) will have:
  • 1 Absolute Hot Wire = Line 1. Normally Black
  • 1 Potentially Hot Wire = Common/Nuetral Line 2, normally White
  • Ground/Earth = Normally Green
High Voltage (220) will have:
  • 1 Absolute Hot Wire - Line 1, Normally will be same color as Line 2 or Black/Red
  • 1 Absolute Hot Wire - Line 2, Normally will be same color as Line 1 or Red/Black
  • Ground - Green
In either of the above voltages, it does not matter which wire goes where, as long as a Hot wire goes onto Line 1 and the other "Hot or Potentially Hot, if 110", goes onto Line 2. Do not put a Hot wire anywhere else and Do Not put a Ground wire on either Line 1 or 2!

Most Motors are coming out of the factory wired for High Voltage Set up (220), so you will have to move some wires or a terminal block, to set the motor to operate at "Low" voltage (115). These motors are "Dual" Voltage, they have the capability to run either 110 or 220. But they don't magically know which voltage is being supplied.

Good Luck

There are large transformers that supply the high voltage needed for the microwave to work. They are normally what goes when they stop working. You need a high voltage meter to check them. A tech. that is equipped for microwave oven repair may be your best bet.

2 blink-then 1 blink-------X-ray protection


You have two of these or one set with different problems, If you got this error the set will of course not come on and stay on.

This like some error codes is general in nature---set produces over 20,000 volts to fire the three picture tubes, hence high voltage.

If the High voltage goes above a certain point the latch or shutdown circuit detects this and shuts the set down to prevent X-Ray radiation which happens if the picture tubes receive excessive High voltage--straightforward and needed, locating the part is almost certainly a shop repair.

I would on this model suggest removing power from the set which clears the errors detected and stored and then power up and try to turn set on again---when it fails check for the error code with the self check again

Power comes on for two seconds then goes off. Trouble code is 21. Is this worth fixing?


The X-Ray Protect circuit monitors:
* Excessive High Voltage
* Excess CRT Beam Current
* Excess HV Circuit Current

The X-Ray line is normally High. If any of the monitored sources exceeds its' specific reference, the X-Ray line is pulled Low, shutting Off the TV. If X-Ray protect shuts the TV Off, pressing the Power button will turn the TV back On ( it will shut Off again if the problem still exist).

Possible Problems: Power Supply Fault, Sweep Circuit Problem, Doubler Board Fault or a leaking CRT. You may have bad capacitors in the power supply or the sweep power supply.

Check for CRT leaking, few drops of clear light oil. If this is leaking the fix is costly and not worth fixing.
Inspect for puffy capacitors on the power supply and sweep circuit boards, if you can solder replacing capacitors is cheap, middle pricing for replacing power supply or circuit boards.

My standby light comes on and blinks seven times repeatedly but no picture.


Hello
Seven blinks of standby light in Sony tv denotes that there is a high voltage problem. It is otherwise called as high voltage shutdown.
Normally 32" tvs has an anode voltage of 27,000Vdc approximately. If it rise beyond its limit, the microcontroler in your set will detect the high voltage, and will prevent it from working further, to protect you fro X-Ray emisson as well as to protect the TVs other components inside the ciircut board from further damages, and will inform you about this fault, by seven continous blinkings of standby light. Now you are seeing this.
The final anode voltage depends very much on the input DC voltage to LOT [Line Output Transformer]. Usually this supply rail will have a voltage level of 135 to 140VDC. If it rises above this level, extra high tension voltage generated by the above said LOT will also rise proportionaly to high, which will goes to the final anode of the picture tube. If this voltage goes very high, there is a chance to radiate X-Rays from the picture tube which will harm you. This high voltage protection also known as X-Ray protection.
The main reason for this fault is related to the regulated power supply section inside the circuit board of your tv. To repair this, you have to open the back cover of your TV. Take every precautions before doing anything to your TV as it is an electrical equipment, which generates high voltages inside it while it is working, and there are voltage points as high as 30KVDC [30,000VDC], wich is very dangerous.
Just open your tv, and locate the power supply section. It is very easy to locate, as the main supply wire goes into it. There will be a regulator Ic, normally Sony sets have STR numbered ICs are used in that section. This regulator will heat up to 75degreeC, and there is a chance to get loose the solderings on its leg points, as continous heating and cooling process. Just look for any loose solderings on the solder side of your TVs power supply section. In practice, I found this in too many Sony sets, during my 36 years in this service field. It is very difficult to detect the exact loose point, so I always do is, just resolder most of the suspected points on the pcb, by applying a little more solder, and will retify the problem. Moreover, just replace small electrolytic capacitors fitted on that board, because some of them may cause this voltage rise. The DC supply voltage rail, will be between 135VDC or so. Any fault in the components fitted around the above said STR will cause this problem. So check every components, and replace if needed. If this does not help replace the STR with same type and number.
Go further with confidence. You can and you will. Wish you sucess. Take care. OK.

When I turn my KV-34XBR800 on, the picture will not come on and the standby light keeps on blinking 7 times each time.


Hello
Seven blinks of standby led in Sony sets denotes a High Voltage Shutdon proble. It is a self diagonosis process of the microcomputer Ic inside it, which senses the high voltage and shuts down the whole system to prevent it from further damages. The high voltage means that not the high line voltage of your househod supply, but the voltage inside the circuit board of the TV exceeds more than normal. Your tv, being 34", have a high tension voltage of 32,000VDC at the final anode of the picture tube. This voltage depends on the main regulated voltage goes into the circuit board from the power regulator system. There is a power regulator built sytem inside your TV, to regulate the voltage send to main board, which bears the Line Output Transformer [LOT], which in turn generated the above said high voltage. The normal regulated voltage going to board may be around 135VDC, to a 34" tv. Even a rise in, say, 2 voltage more than normal may cause high voltage to rise up considerably high enough to get it shut off. Soney sets are normally have STR regulated power supply system. It is very accurate and durable. The main fault comes to it is soldering trouble. The above said STR regulator may rise to as high as 90 degree centegrede when working. Repeted heating and cooling, make the soldering on its legs to get loose contacted; causing improper regulation process. Your tvs case must be so.
You just open your TV, and find out the regulator section inside it, where the AC input voltage goes into. Just pull it out and resolder all suspected points by applying a little more solder; as exact bad solder point is very difficult to locate. We in service field also does this. 90% sure that this will retify your problem.
Take proper care before opening your TV. Keep in mind that you are going to work with an electrical equipment, which have as high as 32,000VDC poins are inside it while working. Take all precautions. Keep children away from you while you works. Never allow them even stand beside you Ok.

Wires to magnetron


It matters!

The wire from the high voltage transformer high voltage tap goes only to one side of the high voltage capacitor. No other wire is connected to that terminal of the high voltage capacitor.

The other side of the high voltage capacitor connects to the anode (A) of the high voltage diode and to the "FA" terminal of the magnetron.

The cathode (K) of the high voltage diode is connected to chassis ground.

The pair of wires connected to the secondary (thinner) winding of the high voltage transformer are the filament wires and are connected to the "F" and "FA" terminals of the magnetron.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

It has the overall wiring diagram and schematic.

Need to install power cord to terminals on 220 AC motor


Ok, read the data plate on the motor. Does it have a zero with a line straight through it. That means it's single phase. Also the plate may list two different voltages 110/220ac correct. On the inside of the panel of the box where the cord connects it will have a two diagrams. One marked low voltage, the other high voltage. You want 220ac so follow the high voltage diagram. Since it's single phase the green wire will go to a green screw in the box. The black wire from your cord is positive and the white negitive (actually neutral but shown on diagrams as negitive). The wire coming out of the motor will have numbers on it's casing. Follow the connection points on the diagram. Don't worry if you hook them backwards the motor just won't turn. It won't hurt anything.
