## Discrepancy

DURING CRUISE FLIGHT WITH BOTH ND'S DISPLAYING WX RADAR, PWS FAIL AND WXR FAIL ILLUMINATED ON BOTH ND'S. AFTER THE WX RADAR WAS OFF FOR 30 MINUTES, WE TURNED THE WX RADAR BACK ON AND EVERYTHING OPERATED NORMALLY. GROUNDED - YES. NO A/C HISTORY. CYCLED WETHER RADAR C/B, OPS NORMAL PER B737-9 AMM 34-41-00-710-801. GROUND VERIFICATION GOOD.
