Toshoba tv/dvd combo. won't play many dvd's. makes clicking sound as it tries to load movie?
It looks, like your DVD lens might get contaminated with dust and/or dirt, which is being picked up off DVDs. Let's try to load music CD, instead or DVD. If it loads well, I will suggest, that your DVD player is at fault and you must give up using it. External basic DVD players are quite inexpensive and easy to connect to your TV. But: if no CD, nor DVD load, the solution might be much simpler: use lens cleaner CD with brushes. good ones might even have a special fluid, which applied to brushes(alcohol based). Just load it into your TV's player and follow audible directions. After couple attempts, your lens should be clean enough to play DVDs. Please, don't try to use any "ear swabs", instead. The lengths is not long enough, plus it may damage load mechanism or get stuck inside. I've seen such a cases lately.
