No Signal Problem

The bracket on the dish will have a scale for elevation angle. Note the readings.

Once you have found any satellite note the azimuth and elevation angles accurately so you can always get back to that satellite. Then note that all the other satellites are in a line across the sky, either way from the found satellite. If you are little north of the equator the line across the sky goes from east to west, up and down, via very high up at due south, like the path of the sun on 20th March 2011.

Step along the orbit looking at each satellite, recording the elevation angle on your scale until you come to the wanted satellite.

Use this https://www.satsig.net/maps/satellite-tv-dish-pointing-south-east-asia.htm to determine where to look.

When you are aimed at the highest satellite, due south of you, on same longitude as yourself, your LNB polarisation should be centered.

Assuming you are north of the equator, when you are aimed at a south easterly, lower, satellite, your LNB polarisation should be turned anticlockwise, as viewed facing forwards towards the satellite in the sky. When you are aimed at a south westerly, lower, satellite, your LNB polarisation should be turned clockwise, as viewed facing forwards towards the satellite in the sky.

You need to make large polarisation adjustments approaching -89 and +89 deg for extreme east and west satellites that are down near the horizon.
