TV Input source Keeps Changing

[Gkerlin]

I've got a small nuisance type problem that has just appeared.

Keep in mind we are boon docking and I'm living off my solar panels and inverter.

Every time I do a "cold start" on the TV - that is turn the inverter on and power up the AC in the camper this problem appears.

After waiting a few minutes to acquire satellites, etc I'll turn on the Sat Tuner and the TV (sat is and has always been on source HDMI 4)

The TV is fine for about 15 seconds or so and then changes to HDMI 1. and the screen goes blank - says something like "weak or no signal".

I go to TV Source Menu - change it back to HDMI 4 - I get the "disconnecting anynet device" message the Satellite feed comes back on the TV and all is good.

I can turn the TV on and off. Turn the Sat receiver on and off and no problems.

As soon as I turn off the inverter (in other words remove AC power from the coach) and restart the system I go thru the same deal.

Not a big problem - just an annoyance but I don't know why its doing it.

I plan on throwing out that POS Samsung DVD system the rig came with and put in a real entertainment receiver but till then..... any ideas?

For what its worth... this just started happening a week or two ago.

Prior to that everytime I started the TV it would work for 15 seconds and then the sound would go out - the picture would remain. I'd turn the TV off and back on and the sound would return and remain.

That prior sound problem started about a month ago (after we were in Quartzsite for sure).

Prior to that the whole system worked just fine with no quirks.

Any thoughts out there?
