Aircraft; Procedure
After takeoff had multiple failures on pilots PFD and Navigation Display (ND). FD inoperative; speed bug incorrect; radio altitude inaccurate; Predictive Wind Shear (PWS) fail; both FD's showed 'MA' on Mode Control Panel. Final straw was continuous warning horn (sounded like the gear horn) that was unsilencable. This horn created a distraction and made it difficult to communicate in the cockpit. We were only 15 miles north of the departure airport and decided to return. Made a normal approach and landing.The frustrating thing about this event was that there was significant repetitive log history with similar failures over the last several days that were signed off.
A B737 had multiple system anomaly indications after takeoff including the landing gear warning; PFD; ND and Predictive Windshear (PWS).
