I checked the connections: TVP7002/Pin23 -> EP4CE15E22/Pin91 & TVP7002/Pin24 -> EP4CE15E22/Pin90 are perfectly fine. I resoldered them nonetheless… but it didn’t change anything. I wasn’t able to get my hands on a scope… so i couldn’t check the signals. I would assume: either the TVP7002 is damaged spits out some corrupt sync signals or the FPGA does something wrong interpreting them?? But without scoping the signals between the digitizer IC and the FPGA no one can say for sure??? Am i right or am i wrong? Any suggestions for what else to test?
