Hello! I found a CRT screen and HV transformer from an old broken CRT monitor from Poland, made in 1988. I wanted to ask you for a simple circuit, because I cannot find anything on the Internet. The circuit should contain HV power supply, analog video processor and deflection driver, so it would be able to display analog video on the screen. This screen was used in Czechoslovakian TVs, like Tesla Satelit, Merkur, Asta... HV transformer has 4 outputs on the primary and two secondaries. HV diode is Telsa KYX20. Thank everyone for answer!

That is a simple schematic, I was looking for something like that, but I cannot see the component values.

 

Search for 'crt monitor schematic', there are lots on www.
Here's another one (more legible).

Yes, I saw this, but I haven't got that HV transformer, I have TVL-60.

 

What was the monitor it was part of?
Do you have the rest of the monitor?

Rest of the monitor is desoldered. It is old brand from Poland TOPAZ (Unitra), it has no type number.

 

It would probably have been easier to repair the old one than to try to rebuild it from scratch.
You will be very lucky if you find a schemstic using the specific parts you have.

 

Is the CRT magnetic deflection and do you have the deflection coils?

 

Yes, it has got coils, it is New one, from 1970s.

Good, because them would be essentially impossible.

 

Do you know for sure that the transformer is meeting all of it's specifications, as far as correct voltages? And do you know that the CRT is still good? Those parts are at least 32 years old and moisture can cause fatal problems for transformers. And if that power transformer does not have a really high voltage section then you will need to create the 12,000 volt second anode voltage for the CRT. Televisions from that era were works of engineering excellence in making a minimum parts circuit function almost good enough. The horizontal deflection system alone will indeed be quite a challenge, even if you are a god engineer. So even after you obtain all of the parts that are needed, and then assemble the circuit, you will still need to adjust it to work.
AND, where will you get the analog video? AND, which format will it be in? There are 3 major ones, all different, They are PAL, NTSC, and SECAM.
I suggest that after you get a complete circuit, that you learn the total price of all of those needed parts.
AND beware that there are published circuits that look sort of OK, but they will not display composite analog video at all.They only provide a non-synchronised raster, at best. That circuit was presented on a similar thread here just a few weeks ago.

 

I Took apart the Monitor last year, because it wasnt working. I desoldered some interesting parts, and then I saw, it is very dangerous construction. It was a funny problem in it, one of the free hidden fuses was blown. Here in Slovakia, we have PAL 15625/50 Hz. CRT is certainly OK, because it was working before blowning of the fuse, in 2004, I think, it was in Operation whole Day, that Day, so it was overheated and the current was over 315mA, what was fuse rating.
