From what I have seen of the videos posted to u-tube about this, there is no such thing as a “perfect” IF or chroma bandpass alignment, just varying degrees of ALMOST there!

The markers 42.17mc and 45.75mc are supposed to be at 50% +/- 5% down the curve and they are currently at 49%. 42.75mc and 45mc are supposed to be 85% +/- 15% and they are currently at 78%. The 47.25mc trap is just slightly off from being perfect too. I can only imagine what negative gain was doing to the chroma signal. It is impressive that the TV was able to draw a picture with how badly it was misaligned. Alignment would absolutely be impossible to achieve without the proper tools, and even with the proper tools, it takes lots of trial and error. Last edited by LukeSimon; 10-23-2023 at 03:21 PM. |
