HP pavilion f1703 problem solved
Got a used one from a thrift store w/ no power supply,date of mfg. was sept 2003.To test operation used a 12 volt battery pack w/cigarette lighter cord,made sure center was + VDC.Within 10 seconds of turning it on,a electronic burning smell came out, display worked for several more seconds ,then went out.Thro google search,found this forum,took apart ,located the problem board(power plug/sound),found a burnt spot on lower high voltage lead to small female recept,reheated all coil solder connections and the blue titanium cap ends(in high voltage line between transformers and on board recepts).I just snipped off the burnt side high voltage wire(blue)from the male plug-in and soldered it directly to the lead side of the cap going to recept on board.From all the other posts, my guess is there was a bad/cold solder joint problem on this model monitor.The board on mine looked different than the board pics show here but the problem was the same!
AND NOW I HAVE A TOTALLY WORKING FLAT SCREEN!
THANK YOU ALL VERY MUCH!
