" E " waste find

[radio nut]

I found a small portable plastic cabinet sears color tv at a recycle center. It is tubed and in nice shape. I did not have my phone so no pics or glasses so I have no idea what model it is. Ok I did notice that the brightness is all the way clockwise so I am assuming all the way up. Yes someone may have messed with it but if it was turned all the way up when running is that automatically scream bad crt or could a tube cause that? All the tubes I could see had sears written on them. For $25.00 is it worth a shot ?
