2. I was watching tv when my sister talked on the phone.
3. I watched tv when my sister talked on the phone.
4. When I watched tv my sister talked on the phone.
5. When I was watching tv my sister was talking on the phone.

thank you

You should use "while" instead of "when" in all five.
Then all five will be correct. The abbreviation for television is capitalized: TV

Emotion: smile

thank you CJ.

I would like to ask two additional questions to clear my doubts.

1)This a sentence form my grammar book ,
I was washing my hair when the telephone rang.
If the above is corect why
2. I was watching tv when my sister talked on the phone.
is incorrect.

2)What is the difference between the sentences below?
a) I was watching TV while my sister was talking on the phone.
b)I watched TV while my sister talked on the phone.

thank you
