  • Picture problem in s-video

    Hello,


    My cable is built according to this diagram.
    Pin 1 of the din is well connected for luminance but there isn't 300 ohm resistor on pin 6.

    Because I read on your wiki that there was a resistor at 3300ohm installed in the chrominance on s-video.
    Now is this 3300ohm resistance also installed on the din 8 - pin 6 ?

    Or is there a specific wiring in din 8 for the C64R?


    Thanks

    Regards.

    Hello Tobia,


    I made several adjustments on my monitor with the contrasts with my old commodre and I don't have the interfaces as on the MK2 C64R.

    Suppose my cable is faulty so explain to me why I have a good image with my old commodore. I tested with a multimeter my s-video cable and all connection is good and my monitor is working fine.


    Regards.

    Hello Tobias


    Thanks for your answer.


    For picture i did't see a option to upload it at my post, sorry.


    My saturation monitor is correctly adjust, It doesn't solve anything.

    It's normal to compare the image of the two machines Breadbin and C64R when using the same video chip. For me, it's a C64 and I expect to have the same quality image and there is no artefacts on the breadbin.

    What I ask is a solution to no longer have this defect ? Either the board is defective or it is a design flaw.


    I did other tests with the game "Big Mac: The Mad Maintenance Man". The character is normally in yellow. On the C64R the character flashes from yellow to green when moving forward ...


    For The TOD See our WIKI ->

    proper 50/60Hz signal for the CIA TOD clocks is generated on board depending on selected video mode. The time base for this is another crystal oscillator, which is running independent of the main C64 clock circuit.


    I said to myself that this could possibly influence the picture.


    Regards.

    Hello,

    I recently bought (1 week ago) a C64R but i am having problems with the S-VIDEO picture.

    The colors are not contained, when looking at the green, there are red parts and runny overflows.

    I put a display comparison photo of the C64R and a Commodore 64 breadbin with the same graphics chip (see url below).

    The image of the C64 breadbin is cleaner, the colors are more contained (the green doesn't overflow).

    The test is done on the same Philips monitor and the same S-VIDEO cable (din to scart).

    The recognition of the TOD is automatic, I tested it at 50Hz but that does not solve the problem

    Is there a solution to this problem?

    Thanks in advance.
