Question about Televison & Video

1 Answer

I have a JVC I'Art 48 Inch Projection TV Model AV-48 which is about 6 years old. The Covergence setting has suddenly gone out of alignment, causing red and blue shodows on the projected picture.. Using menu/convergence using the remote control, I can align the blue curser with the center green cross in all nine positions, but cannot align the red curser left or right to align it (it does align verically but not horizontally). How can the alignment of convergence be done manually at the lenses?

It cannot be done at the lenses. It should be either the settings or the ICs themselves. Time for replacing the convergence ICs? I think yes.

    Is that a plug

    Is that a plug-in component that I can replace myself?

    No its not a plug. Its an IC. It has to be de-soldered from the board and the new one has to be soldered in. Good soldering skills are mandatory. You should also know how to use a multimeter to test the nearby resistors(to see if they are damaged) which may be the reason the ICs have failed in the first place.
