What is the date of defendant's appeal and request for a certificate of probable cause?

Defendant filed a notice of appeal and request for certificate of probable cause on January 21, 2010. The court granted the request for a certificate of probable cause by order filed on January 25, 2010. We appointed counsel to represent defendant in this court. Appointed counsel has filed a brief that states the case and the facts but raises no issues. We notified defendant of his right to submit written argument in his own behalf within 30 days. That period has elapsed and we have received no response from defendant. Pursuant to People v. Wende, supra, 25 Cal.3d 436, and People v. Kelly (2006) 40 Cal.4th 106, we have reviewed the entire record and have concluded that there is no arguable issue on appeal other than the corrections of the clerical errors on the abstract of judgment.
