    My JVC PD-42V475 does the same thing, it went from working perfectly to this after turning it off one night and back on the next day. (there was no lead up, it happened all at once). Additionally, it starts with black pixels several inches around the perimeter that gradually go away after it warms up for a few minutes.

There is a setting on the menu called colour reverse.

Check to see if that is left on. If it is, turn it off and it should be fine.

There are two things that can cause what you see.

The main drive board to the Plasma tube is not supplying proper drive voltage, or proper biasing to the Plasma tube. Or, the Plasma tube itself have gone weak.

I hope you did not pay too much for that screen. This type of repair is very expensive! I am sure that is the reason why the seller put the set up on auction.

I always tell our customers, to never buy used unless you know the seller is reliable, and that you can test the set and have it professionaly checked before buying it.

If you can find a couple of Plasma sets of the same model with a good display tube and maybe some bad boards, you can then do some board swaps to make one out of the two. That is if the used sets you get don't all have the same fault. We've also been through this.

I have a JVC I'Art Pro 42" HDTV ready projection TV. Recently, it started intermittently flickering (Picture would go from correct to negative looking). Now this video circuit problem is negative picture...


It is not video circuits on main controller or convergence.

This TV uses a CRS system with three CRT tube lamps, red, green and blue.

The problem is likely one or more of the CRT individual high voltage PSUs failing intermittently, if problem is associated to vibration, then it is a cold solder joint , otherwise it is a faulty component.

Hi, I just bought a new lcd tv and the picture is great when you look straight at it, but if you look at it from an angle it turns like a photo negative. Please help

Hi nothing you can do about that - sounds reminiscent of the old school LCD computer monitors/ laptop screens. the LCD technology has advanced significanty to170 degree viewing angles to all but eliminate this artefact.

Hello gladwin6,

You may have at least a blown fuse. However you may also have other damage to your power supply. This often happens due to the voltage spike caused by the power coming back on suddenly. You can check to see if the fuse is blown, however once you change the fuse and if this does not take care of the problem, I would suggest that if you do not have a background in electronics, that you have a qualified technician take a look at your TV set.

I hope this helps,
Thank you,
