I managed to recap my "new" Egyptian EP and update to EXOS 2.4
The machine works but I still have a strange noise problem on the RGB signal. See
here.
Any suggestions how to find the source for that?
As far as I can see the components are fine but maybe something "broke" when I turned it on the fist time?
At first boot the machine was dead. Red LED on but no picture. With the help from
this thread i managed to get it going.
The 5V rail was fine but 12V was way too low which cause the TR2 to fry (maybe killed by a bad C9). I replaced TR2 and C9 and the machine came to life
But now I have a noise problem (see video).
To cure that I then recapped the board (took a while
). That is finished now but the noise is still there.
Any suggestions to where I should start looking for the error?
