Image output

Hello, All Help me connect Spectrum 48 (manual assembly, but as they explained to me according to the diagram Moscow) to a TV or TV tuner. 1) I connected Veras to the TV scart. I turned on RGB (I don’t remember exactly the pin numbers), sync on 20 pins, ground on 21. Got a black background with gray font. Further experiments with the color of the border and the work area did not really lead to anything, the shade changes almost imperceptibly. When loading from cassettes, stripes running along not visible to the curb, or rather visible in an area 1mm wide on the border of the working areas and borders. It’s impossible to play games, the colors are almost indistinguishable, ooey grey. I removed RGB, nothing changed. (SCART is not completely soldered?) 2) Connected to the b/w TV Chaika. The TV consists of 2 parts: the whole electronics in an iron box and a separate kinescope. Here I go to the kinescope got cut. I started the earth and synchro. Got a slightly double image. Background It was light gray, the font was just a little darker. The colors are again almost indistinguishable. 3) Connected to the computer's TV tuner. The effect is the same as in the second case, only that’s it much darker. Tell me how to get at least a b/w image of acceptable quality. Looking for I searched, but didn’t find anything similar to my situation. If I didn't look well, please poke your nose.

Hello John North Joh> are you sure you connected the synchro? maybe you got a color instead? I don't think I checked it just in case. If color is supplied instead of synchro, then In one case the screen is black, in 2 others the colors are similar to the correct ones, but the picture It flickers diagonally, there is no synchronization. We need to somehow mix the synchronization and what color? I continue to dig.... having opened the spec case I found 8 two-position switches that affect the image in one way or another. discovered that when turning on one of them and feeding any color + sync for 20 pin scart I get normal image. This means that the output of my spec is pure synchronization, without RGB impurities? Is it possible to simply twist RGB and sync and apply it to 20 pins or Do I need to put capacitors between them or something else? I'm weak in electronics.

Hello, Shnurkov Shn> (SCART is not completely soldered?) most likely yes. Lately there are a lot of such scarts... Shn> Got a black background with gray font. Are you sure you connected the sync? maybe you got a color instead?

Hello Vitron Vit> resistors, capacitors or jumpers are not connected... Basically, everything related to RGB is not wired.

Hello, Shnurkov ..It happens that in circuits there is a scart, and resistors, capacitors or jumpers...

Typically used as a control signal, which tells the TV whether to switch the mode to RGB or not. For to turn on RGB, you need to apply a logical one (+ 1-3 volts);
