Learn Turkish: Erken uyu, televizyon izleme. - Sleep early, do not watch television.

To make a negative command for one person, we take the verb stem and add the negative suffix -me or -ma. For izlemek (to watch), the stem is izle. Because the last vowel is "e", it follows vowel harmony and takes -me, becoming izleme (do not watch!).

Why is uyu just the root word without any suffixes?

In Turkish, the positive command for a single person (the informal "you") is just the bare stem of the verb. You simply drop the -mak or -mek from the dictionary form. So, uyumak (to sleep) becomes uyu (sleep!).

Who is being told to sleep and not watch TV in this sentence?

This sentence is addressed to one person informally, which is the sen (you) form. In Turkish, we don't need to actually say the word sen because the command form of the verbs (uyu, izleme) already makes it clear exactly who is being spoken to.

Why does televizyon come before izleme?

Turkish word order is typically Subject-Object-Verb. Even in short commands like this, the object (televizyon) goes right before the verb (izleme). In English, we say "don't watch television", but in Turkish, it literally flows as "television don't watch".
