Default TELEFUNKEN 3309 (914 chassis) TV

Am trying to fix this set from circa 1978. It's a SECAM VHF/UHF, with 625-819 capability. info

After replacing posistor, fuse and B250 rectifier it powers up and the sound works but just get this bright green raster. Need to troubleshoot the video circuitry, I'm hoping this is not some H-K short or something 'orrible. Anyone have a circuit diagram? I doubt there was a UK version though...Anybody recognize it? Final picture is a 3600 found online which might be easier to see/recognize.

The plastic struts that keep the sub PCBs in place are all broken with age so I am hoping that the cause may yet turn out to be something simple like a cracked joint.
