There are several discrepancies in your letter that affect the clarity of the information.
1. You have not spoken to this friend in a long time. How did you know he changed homes?
2. Again, you have not spoken to him, how do you know that he might be interested in purchasing your TV set?
3. Are you selling your TV because of your need to study?
Additionally, you will lose points for incorrect word usage in relation to the TV descriptor.
Are you talking about the TV frame or the screen display?
If you are refering to the size of the screen, you should be saying "inches" not ink, which is a color reference.
