How to change the configuration of yooke CRT monitor to be used in conjunction with aircraft engine TV. Why should the fox first? because the resistance value is very low yooke horizontal monitor, start-0 0.2 ohm, 6 ohm to value may be in charge to a horizontal deflection circuit of a TV set, 0.6 ohm-1, 8 ohms. As a result the load transistor Horizontal become very heavy so can cause damage directly. This time I will try to give a little information about how to change it.
What should you prepare is. Monitor
1.CRT complete with yooke. TV engine 2.Modul pinchussion or have facilities for model 21 "and more. 3.Trapo yooke (for SVGA monitor or monitors Flat) 4.Elektronik tool (solder, tin, etc.)
First you need to do is, pay attention to the composition of the horizontal cabling yooke, usually there are additional series in the yooke monitors (set of dynamic convergence and pincushion circuit.) Change the horizontal part of this arrangement which was originally set up in parallel to the composition seri.Dengan way off all connection points in each terminal yooke horizontal (vertical section need not be changed). Discard / disconnect all wiring from the additional circuit (pincushion) is, take the ends of the cable spool core of the horizontal rolls, and you'll get four tip line / cable of this horizontal section, two left and two right. Measure with AVO meter to indicate each coil (coil A and coil B). Connect the coil A coil end side kirike B Right side. And the rest of the two ends that are not in connection to the terminal point is that we will use next. The first process is finished. Next you quickly measure the resistance value of the horizontal yooke we have a fox before, whether it has been quite the range of 0.6 to 0.8 ohm with AVO meter precision (accurate digital meters recommended by the AVO). if it is quite ready for use.
to reset the position that has been set in this factory.
This setting is very critical to a CRT monitor because the pixel number for more than a CRT TV, And for that reason I recommend using machines that have facilities TV settings
pinchusion / degree of curvature side of the picture. (character there are two manual trimpot near vertical IC engine TV).
If the size of the horizontal yooke resistance is still too low (at yooke SVGA monitor or yooke monitor 17 "and above or yooke monitors Flat).
We need to use additional components, namely travo yooke wansonic (specially made by the factory wansonic for use by makers of the TV assembly), this trapo many encountered in the market along with the TV machine wansonic.
How to use the transformer yooke are as follows:
1.Hubungkan blue cable TV to the foot of the machine number 1 transformer also go directly to one terminal yooke horizontal.
2.Hubungkan red cable from the TV machine to the last point (pin6 and pin7) from the foot of the transformer.
3.Hubungkan red wire from yooke to one pin on trapo yooke (pin4, 5,6,7) to adjust the width of the image.
