What is the likely problem, and is it likely to be expensive?
Suddenly, while watching, the picture turned to static on every channel, Intermittently, there is a picture that looks like a line drawing in all red, white and black, and then it goes back to colored static. The sound is fine. When I turn the TV on, the internal Olevia brand page that comes up is in perfect color and sharp. The problem with the static exists with all input sources except the internal Olevia welcome screen.. Is this likely to be an expensive repair?

Sounds like T'Con board fault. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

Can you hear any audio? Look behind the TV, you should see some light emitted from a grill back there. If you hear audio and it appears you can change channels and what not, you lost at the very least your back light, which can be replaced , or worse the power supply to the back light which will cost you a bit more than the already expensive backlight.
had this problem for a while only just found the cause, its either your tuner flipped out which means you just neded to retune the tv and it should be fixed if not that there was this setting i found still not sure what it is or means but you could select these letters i think there was S, BG and some other ones but i changed it to the top one which was BG and it fixed the static sound with the clear picture problem just stuff around with the channel settings and see if you have that setting hope that helped
you could be experiencing two problems. the first part of your description states the static with two horizontal bars, this problem is usually erratic and it is caused by a defective varactor tuner(this happens while watching a channel thru your channel selector) the second part that it also happens while using the front hookups could be taht the front input connectors have developed some loose solder connections and thus the video problems (very common problem)
What you are describing is either a fluctuation in the signal strength for a particular channel/channels or a momentary lapse of the actual broadcast signal. The reason why the picture freezes instead of just getting some static in it is because the signal is digital rather than analog.
Toshiba flat-screen digital SDTV, 27", won't turn on. Was difficult to turn on for awhile, but some channels had no sound, others that were in English usually, would suddenly turn into Spanish language. A loud static noise would occasionally come on, and then go. TV just won't even turn on now. Is there any possible repair that would be less expensive then replacing the set? I can't lift the set,as it is much too heavy. I'm a senior, and I'm strong, but not that strong.
Check the aerial cable, ensure it is well plugged in and getting signal.
If you are using a receiver box, check cables to TV and receiver (freeview, sat, cable etc.), try setting channels on receiver again, if it does not work but you get static, then either the cables or receiver are defective.
Test the TV on standalone , connecting it to an external antenna. Tune again the channels, and save the preset. If still no signal then the antenna socket on the TV may be defective.
Try using the TV with a DVD.
If you can watch DVDs, and TV is not keeping channels preset, and you tried all the above, at this point htere may be a fault in the tuner card inside tv.
Call the phone number listed on tv user manual to get support, and eventually repair it.
When not watching a tape, be sure power is off ( VCR ).....
How is the picture...? When you watch tapes, do you put the
TV on channel 3 or select video..? Also, what is signal source ?
Cable ? Box ?.....................T.
Your problem is somewhere between the tuner and video detector circuit.
The signal entering your TV carries: video,red color,and blue color as well as sychronizing pulses for color and horizontal and vertical deflection ( actually vertical sync. is derived from horizontal sync.) along with burst pulses to synchronize the color. After all these, the sound is an fm signal entwined with a pilot signal for stereo audio. WHAT a mess!
After the audio passes through all this, it is detected and sent to the audio processor.
If any frequency has drifted away from it's value then you loose the sound.
SO... your problem could be in any of the tuned circuits or in the audio processor IC (chip). Any component changing value could creat this problem. Most likely the audio processor IC. You'd need to have the set checked out by a tech to find your problem.
