Hi, just got a refurbished Zenith HD520 Hdtv tuner. When I plug it in the picture looks very bad, has purple ghost like things on the screen and a bunch of vertical lines. Do I need a new tuner or can this one be fix easily? Thanks for the help

Hi and welcome to FixYa,

If the TV?Monitor works with other external video sources such as your DVD or game console, then it confirms that the Zenith HD520 tuner is faulty. Of course you could always check the cables from the tuner to the TV, the cables going into the tuner from your provider or antenna.

Good luck and Thank you for using FixYa.

If you just got it you will want to replace it for another one. You don't want to mess with it as refurbs are usually still covered under factory warranty. If you still need any assistance let me know. Please take a moment to accept and rate my solution accordingly.
Thank you,
lee

The main circuit board must have a problem, this is what is called a convergence issue, cheaper to just replace the TV than keeping on throwing money down the hole on this one.

Is the L20V36 zenith ready for the new tv changes


Having looked at the specs for this TV, it would indicate that to receive digital pictures, you would indeed need an external set-top-box, as the tuner in the TV is a standard NTSC tuner, not a DTV tuner.
