Tawfiq Okasha was detained Sunday after he went to a police station to see if any charges had been filed against him, the Egypt Independent reported.
Okasha was released after his attorney appealed two in-absentia convictions for issuing bad checks and a third conviction for stealing electricity.
The status of those convictions following the appeal was unknown.
The broadcaster, a supporter of former president Hosni Mubarak and owner of the Al-Faraeen satellite channel, was referred to trial in September on charges related to comments about new President Mohamed Morsi. That trial is expected to resume Wednesday.
Okasha has denied the charges, saying the trial was politically motivated because he had run stories alleging the Muslim Brotherhood was behind attacks on government institutions during last year's Egyptian revolution.
Okasha had said on his TV show that Morsi's life would be in danger if the president attended the funerals of 16 border guards in an August attack in Sinai.
