We have a Majestic brand 12V LCD TV installed in the yacht we've recently bought and it suffers from intermittent flickering. It will show
images perfectly for a few minutes and then start flickering and after 4 or 5 minutes it will return briefly to a perfect image before flickering again. Doesn't matter if you're playing a
DVD or tuning in to local TV signals.
It seems like its caused by some sort of
interference, however, we've tried switching things (like the
electric fridge,
battery charger,
VHF,
SSB, nav
electronics, etc) off and it doesn't seem to make a difference.
Does anyone have any ideas as to what we should be looking at to identify and isolate any
interference issues beyond the obvious stuff that we've already done (check that all plugs and connections are tight and clean, etc)?
Just a thought, we've only tried the TV while connected to
shore power sitting in the marina berth. Could we be getting
electrical interference from another
boat, the
shore power system, etc? (should probably try the TV while we're out on the
water, but have generally got plenty of entertainment at that time anyway
)
