No channels during most of the day

[d30jo]

I loose channels early in the morning 9:00am or so and don't get them back until 7:00 or so at night. Seems to be channels with negative transponder numbers. I replaced the cabels from the LNB to the Switch box. Anything else?

Temperature sensitive LNB, when sun warms up LNB it fails until sun sets.

So replacing the LNB should solve my problem. I live in Ky, it doesn't get very hot here.

low signal strength causes the lnbf to heat up, which maybe not ver y hot outside, that lnbf is nice and toasty.
either that or you have tall bushes that move with the sun,
never know could happen
