First off I need to know exactly what you mean by basic programs? Is it the same box just different channels? Once I have more information I can assist you further. Please don't request more help until I am able to do so. Also what cables are you using to hook up these "basic programs"
Thanks,
Lee
The colorization is probably magnetization of the shadow mask of the
screen. The horizontl lines are from loss of the vertical blanking
function (that stops the visibility of horizontal lines during the
vertical scan of the raster).
So, first: Try deguassing the screen. If the deguassing coil on the
set is working properly it should gradually remove the magnetism by
switching the set on, leaving it on for one minute, then off, then
repeat. If you have a loudspeaker (most often a subwoofer) nearby the
tv, move it further away.
For the lines, the only way is to have a qualified service tech repair
it. The blanking circuit is complicated in new sets (old sets it was
merely a capacitor that needed to be replaced, but today it is buried
in an chip function). You might try a hard reset to see if that help.
Merely unplug the power cord for 4 hours.
This may help..... The age of the set precludes spending alot of money
but check out the above suggestions to see where it leads. If the
degaussing coil in the set is not functioning the repair is probably
more that one might want to spend on a set of this age.
I like Toshibe products. Even at this age I wouldn't hesitate to fix it
if it could be done for a very reasonable price, however.
this is degaussing problem
keep tv off for half an hour and if you have changed the direction keep it as it was.
if any magnetic thing is there near to tv remove it like speaker or headphone etc.
hope this will help.
Standard-definition TV signals (about 480 visible lines) are blown up to fill your HDTV screen (anywhere from 720 to 1080 lines). The original standard-def TV specifications were optimized for smaller screens than are common today.
THE FIX: Ask your cable or satellite installer to check if DTV signals are strong enough for your set-top box. If they're too wimpy, a commercial-quality inline amplifier (about $80) will provide the missing oomph. If you receive digital TV signals off-air, install a preamplifier (about $60) at the antenna to boost signal strength
THE FIX: If you haven't bought an HD set yet, here's a reason to wait: Future sets will be better at upconverting images to HD. Meanwhile, outboard video scalers can convert a 480i signal to 1080p. Models from Lumagen and DVDO range from $1000 to $2500.
Are you using a satelite dish or cable? Try to play just a normal DVD and check if the same problem occurs. If it does, one of the bulb is needs to be checked. What you can try initially is unplug the power of your TV for about 2 hours then plug it back in. Check if that fixes it.

I have a Toshiba 30" tube TV. I have a cable box with HD. The HD picture is fine watching TV and when I play DVD's the picture is fine. When I switch back to standard TV the picture is purple and green.
I have a 30" Toshiba HDTV tube TV and cable with HD. The HD programs are fine but the standard are purple and green.
