Yes I'll check. I just want to get the picture close and then I'll trust my eye to adjust it with normal viewing of something.

I think you missed the point. A generator is supposed to put out a perfect reference pattern. A generator can be used to do a final checkout of the TV, you can see problems that you might not notice with a normal TV show.
If you never try the generator on other TVs or hopefully a very well operating TV you can never know whether the fault is in the generator or TV.

Got it. Thank you. Another question specific to this TV. The tuner does not appear to have any channel detents when I rotate the VHF tuning knob. There is very slight resistance at around half of the channel numbers but essentially, the tuner is behaving like a smooth FM dial tuner. I was able to rough and fine tune in channel 3 and get it stable without physical drift in the tuner but before I go opening the tuner up to see what's going on, I thought it would be best to put this out there to check if the condition is a broken tuner or that it's supposed to be this way.

TIA
