K so when im taking pictures with my 7d on TV (shutter mode) the f stop number is blinking. i cant get the shutter speed over 50 without underexposing the picture. i.e. if my shutter speed is 1/60, 5.6 will be blinking and the picture will be underexposed. never had this problem before... sorry if its a repost, searched and couldnt find anything.
thanks in advance
