Is this likely a problem with switch or receiver?

[waltinvt]

Have 942 one room, 508 in other.

Dish 500 with 2 DP LNBs for 110&119 and another small dish for 61.5.

The 3 sat lines run into a DP-34 which outputs 2 lines tp 942 and 3rd line to the 508.

942 sees all 3 sats fine.

Recently 508 started loosing signals and / or giving switch error messges. Usually a switch-check and / or reboot fixed it.

Now the 508 will only see the 119 sat. Neither switch checks nor hard & soft reboots will help. The 942 is still working fine.

Before I try climbing a snowy roof to check switch I just wanted to know if this is more likely the 508 going bad or a problem with the DP-34?

Side question: If the 508 is bad and I replace it with the 942 and then get a 622, can I just get away with running the 4th line out of the DP34 to the 942?

Thanks

Easy way to tell if it is the receiver, swap the receivers out. If the 942 works with the 508's line then you know the 508 is bad.

You also might want to check any crimped connections. I was having the same problem on one of my 301's. I would start getting the aquiring sat signal error message and then later I would get the switch error message. It turned out to be a bad connector at the grounding block.
