Do you work in the States? I'm a truck driver, too. I'm usually driving on the route between Germany and Poland, and I use it quite often. Sometimes, it just wouldn't turn on. Chat support said the problem was with the batteries. I wouldn't have even thought about such a small detail. I asked my daughter to look into it, and she found the
user manual for Craig CHT913. It turns out you need to use the right size and type of batteries and check the polarity. Now I always take out the batteries before a trip if I'm not using the TV and clean the contacts. The manual even has a warning about button batteries. Since then, my TV has been working without any problems.
