I have tried different frequencies adding and subtracting. Looking for the strong stations, copying their frequency and inserting it to the code but the problem is not that, the VCOs in the tuner don't work. I also connected BP BM together +5V, there's a jumper in a schematic but those things make no difference. I once replaced to trim-poti with 100k instead of 10k I'll reverse that may be after all the modifications some wonder might happen, From my experience in tweaking if there's a signal of a station there's a chance of grasping it through adjusting fiddling here and there. But I have the feeling the Chip inside is not responding.
There's some simplification in the diagram. The TA2003 is a whole modified Chinese radio. I'll post images though they might not give clues as they're "dead bug" constructions.
