What you described in your mail is a rolling picture with normal colors (I assume via SCART). Also you mentioned you measured the sync signals on the V9958 to be correct.
Did you do more modifications than just replacing the V9938 with the V9958?

Hi erikmaas Smile

Actually, we did not change anything else. However, there was some surface damage near the vdp, but we're not actually sure if it was there from the beginning. The traces have been fixed, but testing them properly was impossible without the schematics Jipe kindly scanned for me Smile We'll start investigating the poor Philips as soon as my skilled friend has time.

I'll post a link to the scans after checking it's ok from Jipe.
