My color television has given me nothing but a headache. I was able to buy it a little over a year ago because I had my relatives give me money for my birthday instead of a lot of clothes that wouldn′t fit. I let a salesclerk fool me into buying a discontinued model. I realized this day later, when I saw newspaper advertisements for the set at seventy-five dollars less than I had paid. The set worked so beautifully when I first got it home that I would keep it on until stations signed off for the night. Fortunately, I didn′t get any channels showing all-night movies or I would never have gotten to bed.

　　Then I started developing a problem with the set that involved static（静电）noise.For some reason,when certain shows switched into a commercial, a loud noise would sound for a few seconds.Gradually, this noise began to appear during a show, and to get rid of it, I had to change to another channel and then change it back. Sometimes this technique would not work,and I had to pick up the set and shake it to remove the sound. I actually began to build up my arm muscles(肌肉shaking my set.

　　When neither of these methods removed the static noise, I would sit helplessly and wait for the noise to go away. At last I ended up hitting the set with my fist, and it stopped working altogether.My trip to the repair shop cost me $ 62，and the set is working well now, but I keep expecting more trouble.
