So, from time to time there were short periods when new sources came out and the TV makers had to scramble to cope with what the game hardware designers did.

I'll try an RF modulator, but it will have to wait until I get my PS2 back. I loaned it out (with the durn component jacks) and all I have is the RF switch (given the design of the PS1's RF switch, it appears to be a modulator.) strangely, this tv worked with my Atari and my NES toploader which put out much weaker signals, btw.
Sony used to mod the PSX consoles back in the day for customers to play on their zenith sets. I can't find one of the daughter boards they used to use anywhere to fix this, though.
