I'm only getting half the transponders on most sats, the first time I've seen one do that. I can hit Russia today on 97, but nothing on the v-side. Can get the Research channel on 123, but no equity stations. Get Montana PBS but no V tps, etc.
Turbosat,
Your receiver is different than mine, but I would like to describe a problem I had with one of my Coolsat 5000 receivers so that you may have some additional ideas of things to check regarding the V and H TP reception.
I had one Coolsat receiver at my cabin and one night, a few days after an electrical storm, I came to the cabin to find the receiver totally dead. I did some troubleshooting and found IC51 blown apart, or should I say blown away! This IC is a programmable voltage reference/regulator. I found a replacement for this IC from Future Electronics in Overland Park, KS.
However, there was more damage than just this one IC and I couldn't locate all the parts I needed.
I went to E-Bay and found a used Coolsat 5000 for a dirt cheap price. I bought it so that I could hopefully either salvage the P.S. to repair my own unit or replace it entirely.
I hooked this new used receiver up to verify if it was a junk item or if at least the P.S. was in tact and operational.
It fired up just fine and after setting my own parameters to match my switches and motor setup, I was able to scan for channels. Not deeming it necessary to repair the blown receiver, I just continued to use this used one.
A few days later, I noticed that I wasn't receiving any signal from the vertical transponders.
I had fabricated a little tap jig so that I could insert my voltmeter or ammeter in-line to check the receiver output voltage or current to set the backlash adjustment on my motor. I connected my voltmeter to this tap and found that, even when I was selecting a vertical polarity signal, the output of the receiver was at 22 to 23 volts! When I checked my good receiver, it was reading 12.8 to 13.6 volts for a vertical TP and 17.6 to 18.4 volts for a horizontal TP.
If I turned the receiver OFF and allowed it to cool to room temperature, it would be fine.
I ended up swapping the P.S. from this unit into my original unit and fortunately, the mother board in my original receiver was still ok, and has been working fine ever since. That was about three or four years ago I guess. So the P.S. in my original unit and the mother board in the one I got off E-Bay were bad, but I was able to make one functional unit by robbing parts from one or the other.
This was a unique situation as normally you would have some cable problem which resulted in a low voltage condition at the LNBF. This low voltage would create the scenario where you wouldn't be able to switch the LNBF to the horizontal transponders, which require ~18 volts. My receiver's output voltage went to 23 volts and would not change to 13 volts.
I wouldn't expect this to be your problem, I think it was a rare case. However, I thought you would appreciate the story for future reference and maybe, as a long shot, you could check this.
