Narrative:

I am a new hire. Third trip off IOE and still learning. First trip of 4 day that starts in the afternoon from ZZZ to ZZZ1. I arrive at aircraft 50 mins prior to departure. Begin to initialize B737-800 IRS's and program ACARS. After a few mins things don't look correct. It is the aircraft's first flight of day. Logbook is signed off and all paperwork in order. As captain arrives; we doublechk cockpit and notice several circuit breakers pulled. Also; right thrust reverser light illuminated. We contact maintenance and reset circuit breakers. IRS's begin to align. Right thrust reverser light still illuminated so maintenance comes out to aircraft. I do my walkaround as a maintenance person watches right engine from outside as another maintenance person activates right thrust reverser from cockpit. Once I am back inside cockpit; the maintenance person clears our aircraft and everything is ok. Captain is PF. After departure; he engaged autoplt. After a few mins; the stabilizer out limits light illuminates (I think that is the name of it). The autoplt disconnects. We get out checklist. As we run the QRH checklist; we both look back at circuit breaker panel and notice a large red flag on the captain's side circuit breaker panel. During the maintenance checks and my preflight; no one noticed the flag. We removed the obvious maintenance flag and reset circuit breaker. All aircraft components worked. Apparently the aircraft was under routine maintenance and the maintenance personnel did not reset the breakers after completing his signoff. I did not notice the breakers initially (my fault); but the large red flag was missed by everyone! It was such a large flag and no one saw it. Very upset with myself and captain even made comment about how maintenance left aircraft trim and other items out of range when we arrived at aircraft. Being new did not help with missing this little item.

Title: A B737-800 NEW FIRST OFFICER DESCRIBES THE COCKPIT STATUS OF NUMEROUS UNDOCUMENTED CIRCUIT BREAKERS PULLED DURING PREFLIGHT. STAB TRIM CIRCUIT BREAKER WAS ALSO PULLED AND FLAGGED; BUT NOT NOTICED UNTIL AFTER DEPARTURE.

Narrative: I AM A NEW HIRE. THIRD TRIP OFF IOE AND STILL LEARNING. FIRST TRIP OF 4 DAY THAT STARTS IN THE AFTERNOON FROM ZZZ TO ZZZ1. I ARRIVE AT ACFT 50 MINS PRIOR TO DEP. BEGIN TO INITIALIZE B737-800 IRS'S AND PROGRAM ACARS. AFTER A FEW MINS THINGS DON'T LOOK CORRECT. IT IS THE ACFT'S FIRST FLT OF DAY. LOGBOOK IS SIGNED OFF AND ALL PAPERWORK IN ORDER. AS CAPT ARRIVES; WE DOUBLECHK COCKPIT AND NOTICE SEVERAL CIRCUIT BREAKERS PULLED. ALSO; R THRUST REVERSER LIGHT ILLUMINATED. WE CONTACT MAINT AND RESET CIRCUIT BREAKERS. IRS'S BEGIN TO ALIGN. R THRUST REVERSER LIGHT STILL ILLUMINATED SO MAINT COMES OUT TO ACFT. I DO MY WALKAROUND AS A MAINT PERSON WATCHES R ENG FROM OUTSIDE AS ANOTHER MAINT PERSON ACTIVATES R THRUST REVERSER FROM COCKPIT. ONCE I AM BACK INSIDE COCKPIT; THE MAINT PERSON CLRS OUR ACFT AND EVERYTHING IS OK. CAPT IS PF. AFTER DEP; HE ENGAGED AUTOPLT. AFTER A FEW MINS; THE STABILIZER OUT LIMITS LIGHT ILLUMINATES (I THINK THAT IS THE NAME OF IT). THE AUTOPLT DISCONNECTS. WE GET OUT CHKLIST. AS WE RUN THE QRH CHKLIST; WE BOTH LOOK BACK AT CIRCUIT BREAKER PANEL AND NOTICE A LARGE RED FLAG ON THE CAPT'S SIDE CIRCUIT BREAKER PANEL. DURING THE MAINT CHKS AND MY PREFLT; NO ONE NOTICED THE FLAG. WE REMOVED THE OBVIOUS MAINT FLAG AND RESET CIRCUIT BREAKER. ALL ACFT COMPONENTS WORKED. APPARENTLY THE ACFT WAS UNDER ROUTINE MAINT AND THE MAINT PERSONNEL DID NOT RESET THE BREAKERS AFTER COMPLETING HIS SIGNOFF. I DID NOT NOTICE THE BREAKERS INITIALLY (MY FAULT); BUT THE LARGE RED FLAG WAS MISSED BY EVERYONE! IT WAS SUCH A LARGE FLAG AND NO ONE SAW IT. VERY UPSET WITH MYSELF AND CAPT EVEN MADE COMMENT ABOUT HOW MAINT LEFT ACFT TRIM AND OTHER ITEMS OUT OF RANGE WHEN WE ARRIVED AT ACFT. BEING NEW DID NOT HELP WITH MISSING THIS LITTLE ITEM.
