Hardware / Problem RGB - SCART.
« on: 2020.December.07. 22:32:29 »
Hi.
 I'm new to the forum. I bought an E64 from egypt and started it. I changed the capacitors and measured the power, it is 5V and 12V.
I made a plug for RGB - scart for TV. Here's the problem: it can't catch sync. The image is in color but it floats diagonally to the side and up and down. The resistors are RGB and CSYNC. First I gave 100 ohms, then changed to 330 ohms. 12V is connected to pin 8 on SCART and from 8 to 16 a 470 ohm resistor. There is still a problem. I measured RGB multimeter and it's 0.2V CSYNC has 3V. I tried to lower the Volts on CSYNC with a potentiometer (resistor) but it does not change either. The same effect is present on two TVs. I also have a second E64 and there is the same trouble.
I don't know what to look for. Can someone help me - give me a hint?
