Strange front television issue
Hello all. After months of prep, we're finally off on our first multi-day trip and the motorhome (08 Berk 360QS) is performing well. We have developed one strange issue with the front - Westinghouse television. We are connected to park cable and the picture 99% of the time is wonderful. Every once in a while, the tv picture will freak out, hard to describe. Not like static, but more like interference. Audio stays fine, picture is all blue snow. I can change inputs and it's the same - but after a few minutes, it comes back and may be fine for an hour or just 10 minutes. I've been trying to determine anything common. For sure it's not time specific, channel specific, nothing is happening in the coach, no change in power, no washing machine, no toaster, no AC, nothing specific. It also happens on over the air tv - not cable we found out today also...
I thought I'd try plugging the tv into a different outlet but I cant get to the power cord without disassembling the tv surround. Anyt ideas out there? The back tv does not display the same issue.
