Hi Guys, I know this is a shot in the dark but I have a friend with a bowling alley that has a bunch of Zenith RGB monitors (he can`t find the model #) and one of them has a flat line running across the screen, I need to know the designation number of the vertical IC so he can try swapping one out from another board, tia, Larry E Larry Eastman American TV & Electronics Crystal River, Fl. 34428 ----------------------------------------------------------------------------- Lost Password: http://www.tech-assist.org and select "Login Problems?".
