    I have several SNES's, along with an Everdrive. But my go to whenever I purchase a CRT in the wild is to bring an old digital camera that has composite out. I extract a few of the image files (grids, linearity, color bars....) and play them on the TV. It's just that simple. People overthink this all the time (console, cart to run the program, etcc..). True, you can't run the whole suite that way but you can use the image patterns for a quick reference.

    Monoscope replaced “Linearity”. You can check linearity by darkening the monoscope 6 clicks til the white is almost gone and the red box is very pronounced. Then you adjust til the red square is truly “square”, and that should do it.

    Great video! I'd love to see correction of really bad geometry. I have a Samsung slimfit that has an amazing picture, but geometry is terrible w/underscan. Service menu allows tons of adjustments, I got it better but not great.
    It also has a 'zoom' feature which expands the image to extreme overscan. Maybe I need to work backwards w/zoom enabled? Thx!

    I use to use a land line phone and take the ear piece and rotate it slowly in and out to fix Purity issues like that. Hope that helps!

    My Panasonic TV has issues with horizontal scaling and crooked corners causing a bit of a funhouse mirror effect, but my menu only has H-POS and the vertical adjustments. How would you recommend adjusting it?

      I wouldnt be sure, you'd have to check if you might be able to adjust any part of the circuit that interacts with the horizontal picture even if it means soldering in new resistor/capacitor values

      @P-0-Seventeen Thank you! I think for now I'll just live with it as it's only mild issues, but I'll look into that if it gets worse

    Hello dude, I have a very similar Panasonic TV, a 27 inch Panablack late model, with the exact same service menu and the same vertically flat screen. Could you PLEASE, PLEEEEASE share your adjustment values with me? Not all of them, only from the HDEF to the VDEF sections. My TV came out of the box with the yoke misaligned a couple milimeters to the low right and I thought i could correct it using the service menu. I screwed up the image a little and now I can't go back to defaults. I've looked everywhere for a CRT technician but it seems they've all freaking retired!! Please, PLEASE, in the name of humanity, share your values with me :( if you don't want to write all the names, just put the numbers and I'll assume you're going from the top line of HDEF to the bottom line of VDEF, from left to right.
    Thanks in advance, I hope you can give me a hand.

      It was just from earth's magnetic field, larger tv's can be difficult to fix those issues

      240p test suite is available for most retro consoles (ROM format, like you are downloading a game) you can get it for nes, snes, ps1. Search for it on Google.

      He said you have to buy a cart if it's a cartridge system or buy/burn a CD/DVD if it's PS2, Dreamcast, etc
