Hi,
I have recently got hold of a PM5503 and find it uses the TEA1002 encoder IC.
After looking at the data sheet it seems it is possible to get a different set of colour bars by changing the state of the inv pin 1 on the IC.
I'm thinking this might be an easy mod and would mean I would have different colour bars to be looking at when I'm trying a colour set out.
regards Peter B
