Hello Adder
Thanks a lot for your feedback, acutualy i leave the brightness control on Varth a little more tweaked to force to see the strange kind chess patterns you can see clearly, some ghosts bars on vertical and horizontal, it happens on certain background with solid colors specialy grays.
Iīm looking to enable C-sync on Crt_Emudriver to try to improve that, and stay only with 1 wire on H, to try to solve that.
About the Jailbars effect i will look for 47uf 160v on chassi as mentioned on pdf, and test the cap. but i have a feeling it is sync related, maybe 1k on H and 1k on V, them twisted both resulting in a single Csync tv doesnt like it very much, so thatīs why want to test Csync directly eliminating the V wire, and see what happens.
Any other suggestion will be very appreciated.
Thanks
Marcos
