I have and love 2 Toronado trofeos...a 90m and a 91. The 90 has t the color touch screen and it works for a while then the tv screen pulls the verticle white line...everything works just fine, radio, A/C and heat etc its just the tv screen has the verticle line. I bought another used one and replaced it...it lasted about 3 days and did the same thing. Any help? Fixes? replacements to buy? Thanks everyone!
