Xerox Phaser 3500 - installed new toner still says it needs replaced. Is there a way to reset the message? We have powered off/on and it still says that it needs replaced.

the only way to reset the message is to replace the cartridge CHIP with new one or reset the chip with proper CHIP reseter(but i don't think that you have reseter).
This printer can write on cartridge chip and sometimes when you replace cartridges the printer writes directly the information from empty chip to new chip and that makes new chip EMPTY. This is some kind of bug. SORRY!!! CHIP is cheep so don't happy

A faint thin, line across my toshiba 32 inch. It was built in 1989, but I don't have idea what model it is. I replaced a few caps around the verticle IC, and the IC itself. I still get the same thing,...

the conversion chip is powered by seperate power from the transfomer + -- volts
here is I believe what your conversion chip # is stk392-110t and here is the NTE specs.
you can use the specs. to check voltage pins, ect.. ,if that is the numbers.
to see if the chip is faulty then check resistors, caps , and voltage to the chip , a pr or fuse may have blown for the - and + voltage to the chip. if it is bad it would be wise to replace the vertical deflection chip as well ( hopefully yours is still ok) , because of the vertical control in the conversion chip.
you can also check for the power on the wires from the CRT board that comes from the flyback transformer ( NOT the HIGH VOLTAGE wire ).
also after you have unplugged the tv and dicharged the flyback to the chassi ground you should check the components on the crt ( cathode ray tube ) board for any bad measurements of the components.

If you are in the service mode, pressing the muting button saves the convergence values to memory.
