From monitor to do TV

From monitor to do TV When someone else 8 years ago I bought my first computer and a conventional monitor with a cathode ray tube, the years have passed and I have not one but three devices and old monitor played in the background. I beat him to a regular TV for a summer kitchen, a wife most of his time and likes to watch soap operas while the pancake bakes, so I had to realize that such a small design and remodel your monitor to the TV, and that will tell further. The theory of this decision, I learned in talatah his friend, he electronics is engaged on a professional level, often reworks old monitors and resells them slightly more expensive as TVs for cottage or garage.
a Normal monitor is 98% ready TV and you only need to install some blocks and all, you are not just a monitor and a workable TV. Need a color block, the unit radio channel and a control unit. I have all these units bought on a radio market ready. They almost elementary placed in the display Cabinet. All in all it took me Saturday and Sunday monitor already existed, and was a new Samsung TV. Let us start with the fact that the cost of a video feed himself and the native control unit throwing, them to sense will not be, and new blocks fastened as anyone. I used the boards here are for your monitor - TV
1.DBK-3-32 (unit radio channel from the TV C-415)
2.MC-31 (bought be what caught, it is not essential)
3.The sit-405 block with the BAP-45, as well as the remote control at the infrared rays
4.Put the tape recorder Spring speaker 202, the hole was not so I had little more creative and install.
and How to connect here you can see the pattern is a block diagram of components and parts, the fact that I added, circled with a dotted line. Those connections that need to add, I pointed out, everything else is unchanged by the print monitor.
In principle, as the blocks are this is not prentsipialno, so this scheme I is not attached.
All according to the scheme I connected the wire harness from the power supply and directly between all modules.
do not forget to alter the charge MGSR in module strochnika. There need itoat transistor KT 315 with some piping. To he will stand in the gap between the connector HR/13 . See where to solder everything is drawn. This revision is necessary for synchronization of the generator in the chip, we reverse the signal and everything works more stably. In the scanner put on the scheme a couple of resistors (in this scheme R1 and R2), they need to limit the voltage.
When all have gathered, we will need all sequentially according to a certain method to configure if you know how to do it, then I think the question does not arise, but do not know look at me here on the portal theme setting on the TV and everything is clearly described. If you have free time, read up at your leisure with the book, adjustments and repairs of colour TV sets", wrote S. A. elyashkevich.
Well here I will briefly tell you that as a Yes
1.Measurement of the output voltage of the power supply. Everything should be normal.
2.The modulator goes I 30V, need to twist the resistor R1
3.Further adjustment in the block sit find any TV channel, how to do it in any instructions of the TV.
4.So the sound is possible in the limit to regulate the change in the block of the sit-405 R34 on the value 1 kOhm
5.In block DBK-3-32 justorum resistor R7 minimum volume. The maximum sound achieve adjustment R28 on the unit radio channel.
6.When the picture already appears ghonaim in the color mode setting in the block MC-31, how and what to read in the book that I recommend, So you need to write a lot, think for yourself read. The main thing that the output stage was supplied with the reduced voltage of about 170-180 C.
7.Well, in the end the whole marathon in transforming the monitor into a TV we remove distortion adjustable block scan, so to speak Zentrum picture. That is all in principle, not difficult and real.
