>Could it possibly need the SCART ports resoldered?
That would be a good idea, but are you sure that your cable is good?
You might be able to unscrew the SCART plug and look inside, if you see thin unshielded wires then the cable is causing that.

>28" Trinitron from 2002
I tried to improve the convergence of my 24" Trinitron from 1991.
I got the middle perfect and the lower right corner is great but the upper left corner is kinda terrible and lower left, upper right corner is just a little off.

The DC input goes through a fuse and the switch then to the 7805 Voltage regulator and the audio amp, as long the voltage spikes that could appear aren't higher than 32V it will be fine.

>Used it with a little Japanese handheld TV. Wonder what sort of input lag I was getting?
Depends on the technology, but for LCD/TFT it could be between 1-5 fields.

>SCART is just one kind. It's actually a pain in the ass compared to the BNC connectors
>since you need to wire it for audio and hook in all sorts of 12 and 5 volt lines and ground crazy things,
12 volt (or about 9V to enable 16:9 on supporting sets) is for automatic switching, it could turn on a TV from standby (quite uncommon feature) and it automatically switches the TV to the SCART input (you can leave this out if you want).
For 5 volt you can use a 180 ohm resistor to form a voltage divider because SCART has 75 ohm termination on the RGB blanking line, the result of approx. 1,471V is enough to enable the RGB mode (1-3V are needed).
RGB voltage is only really needed when the TV can't enable RGB manually.
The RGB lines itself are 0.7Vp-p AC-coupled almost like VGA with 0.7Vp-p DC-coupled, but many SCART TVs will accept DC-signals (but not vice-versa with VGA monitors).
The great amount of ground pins are actually useful for soldering shielded wires (pic related) to the socket/plug, because they are placed right next to the signal pins.

SCART is actually a pain in the ass if you want to plug it in on a setup where you can't easily reach the back of the TV.
