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.

Hello
During vacume back, some plug in connections may be got loose contacted, due to the suction power of the cleaner. You just open your tv, after unlug it from mains supply, and pull out and replug each plug ins, for two or three times. Again you feels the probelm is not resoved, inform me through Fixya. OK.

Tv out of foucs


These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

Hello Skinno, Frist of all make sure that you are set to Antenna input and then connect your antenna to the TV this will pull in the VHF ansd UHF channels. Then perform the auto channel select. If this does not work perform a manual channel selection this should clear up your situation.
