Sounds possibly like image retention. If you watch the same channels often any recurring text, logos, or graphics, especially white colored, can ghost on the screen.(playing the same videogame for a long period can also have the same effect) Watching other programs or channels will cause the ghosting to disappear.
To prevent image retention you need to activate the TVs anti image retention mode(Called ISM Method). On Zenith and LG (the manufacturer of Zenith T s) plasma TVs open the TVs menu, select the Option section (picture of a briefcase with a wrench). Select ISM Method and change it to Orbiter, this is reccomended if you watch programs or channels (or play videogames) that have still images for long periods of time. It moves the image a little every couple minutes.
If watching others channels or programs doesn't make the image disappear, change the ISM Method to either Color Wash or White Wash (don't use White Wash frequently, it over excites the plasma gas and can shorten the life of your TV if overused) for a few minutes and then return to Orbiter.

Problem with the Zenith Z50PX2D 50 in. HDTV Plasma Television
While watching, TV made a sharp bang sound. Sound still good, channels can be changed, but no screen, now tv wont come on at all?
The way I have it set up - cable box out to AKAI cable in, video and audio out of AKAI into TV via RCA. AKAI on channel 3, tv on RCA input. Change channels on Cable box, works fine. To watch a video, just put it in an hit play. Might have to change sources on AKAI if this is not working for u.
the problem is with the control panel of your tv...make sure your remote doesnt have any part in this...just remove and the batteries and check if the channels still are changing.....see if the onboard switch for channel changing is stuck ?..if stuck u can use homemade tools to pull it back......if your tv is within your gurantee period...just giv a call to customer care....if not u can take it to a local repair shop...there is nothin that u can urself do to make it right ...sorry....for further info contact at
There are a few things that can cause this. #1 most often cause is
either something spilled on the channel button or something wrong with
the bezel where the buttons are located causing the button to be
pressed all the time. Check the buttons on the tv and make sure none of
them are stuck. #2 is a bad button (switch). Replace the switch or the
control board. #3 is a short on the wiring harness going from the
switch to the mian board. Maybe it's squished against the frame
somewhere. #4 would be a bad main board. You will likely have to take
this unit to a service centre to have it looked at.
It sounds like a stuck button or switch. What happens when you hit the channel DOWN, does it still keep scrolling down?
Is this with or without the remote?
Have you tried it with the remote and or the TV?
Let me know whether you are changing the channels with the remote or the buttons on the tv and I can try to give you a couple more suggestions. Mac =)
