I'm not an expert, but I have determined that the vertical bars that are often red, sometimes blue ... and sometimes both ... are related to a bad control board. I've also read that a common fix is to buy a repair kit with includes the ysus, zsus and control boards ... all replaced together. My experience was that after a month or two with the 1.5" wide stripes, that you eventually loose the entire picture and have sound only. MIne comes back, but won't stay working for very long and the stripes are always there (buy used to fade and flicker sometimes). I'm planning on replacing the control board.

Here's a link to order the original the JVC upper Y-buffer board and lower Y-buffer board for this model from a major parts distributor if needed:
JVC "PD-42DX6" Replacement Part Upper Y - Buffer Board (LJ41-02760A)
JVC "PD-42DX6" Replacement Part Lower Y - Buffer Board (LJ41-02761A)
Based on the symptoms: It is possible that the Y-buffers are faulty, which may require the replacement of the Y-sus board as well. You may want to get a local technician to diagnose the unit and provide a second opinion.

You did not say if the first one went back for the same fault. If it went back for a different fault then this set is faulty! If not then unless it it more susceptible to RF interference possibly mains borne than the flawless set (that is possible) and you have some other equipment in the house which is radiating like a power supply or dimmer or whatever, it must be faulty. Turn everything in the house off just to be sure nothing is causing interference. Even then it could be picking up interference from elsewhere. What affects it or does it seem random (position time of day etc.)? The only way to be truly sure is to try it in another location
If it's new why not return it?

THIS set uses 2 boards inside--one drives the left and the other the right side of the screen.
You have to id which is which (GOOGLE?) AND replace it-every brand has different names for these but it sounds like your problem
Some research (you or me) should give a board breakdown for this model---not looking for main or power board but another like sustain etc. and there will be 2 listed (for right and the left sides)
