I recommend transponder 12152 H 20000 as it is not duplicated on adjacent satellites and reduces the chance of a false positive.
LNB Type: The screen shot shows the tuner setting of 9750/10600. Is the LNBF a Universal type with LO 9750/10600? If not, change the LNB setting to match the LNBF type and LO. If the LNB type and LO setting does not match the installed LNBF, frequencies will not match and it will be nearly impossible to locate the satellite.
LNBF Placement: Is the replacement LNBF placed at the EXACT position, angle and distance from the reflector as the original feedhorn? The center of the LNBF throat cover must be placed in the sweet spot where the reflected satellite signals are focused. If the replacement it not in the exact position as the original, either the signals will not be focused inside the feedhorn opening or the dish aiming will need to be aimed at a different angle. This will result in poor performance or no reception.
LNBF Skew: I see that your location is in Louisiana. This means the satellite is West of your location and standing in front of the dish, the LNBF rotation will be counterclockwise. The amount of rotation is determined by your location. Use
www.dishpointer.com to calculate the LNBF skew rotation and the dish aiming. The signals coming g down from the satellite I'd linear polarity.
When a satellite is directly South of your location the vertical and horizontal polarity signals would come straight down at 12 o'clock and 3 o'clock and be received with no skew rotation. When satellites are located East or West of your install location, the vertical and horizontal signals arrive at a different angle and the feedhorn is rotated to align the vertical and horizontal antenna probes to match the skewed angle.
