I live in Finland (europe) our old game system have the "pal curse" the games are slowed down from ntsc 60hz to work with pal 50hz so they are like slow motion movie scene.

I think it displays much better on that mini TV than on my mini TVs. What CRT does it uses? Shadow masks are all of the same "pixel" size? Maybe ist a monitor CRT?

+1, I'm also pretty sure to have seen one of these color 5" with larger phosphour size (I can assum not all being equal).

I think it was labeled as 6" somewhere.



Here is update on where we are today: i see that the old photos are not available, shame. The tv is now having new shiny plastic for the screen and i also had made a new sticker for it. Tv also at one point started again making noise and black horizontal lines would come back again when cranking up the brightness or contrast knob. I wiggled all the connections and some times this seemed to effect. Then i took my soldering iron and re soldered the ground wire for tube, didnt help, then i re soldered every big connection at the neck board and after that i could again go high with brightness and contrast and no problems!

Hi to all,
Hi @pjaska,

Congratulations! on going viral with your "play anywhere" video games.

Small color CRT resolution:
in my opinion, the 140BYB22 (5") used in JVC's CX-500 color combo units has the best resolution. Why? because although being an in-line CRT, the phosphors are fine dots instead of the elongated vertical slit shape seen in many others such as the JVC CX-610 series.
Two screenshots below. Forum size limitations reduce the true sharpness of the images
