My toshibia model 27d46 tv will not turn on

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.
