I bought an LG 15" LCD TV back in March for our RV. Tested it at home
first, worked great. First time we used it in the RV, the cable
channels were kind of snowy. Wasn't sure if that was the fault of the
cable at the RV Park. On subsequent uses it didn't work at all - so I
realized the tuner was shot (haven't even tested the digital/HD
component yet). It was too late to exchange for a replacement at the
retailer, so I had to bring it in to be serviced. Luckily, LG has a 2
year warranty on their LCD TVs, so that wasn't a problem. They told
me it was the "Main Board" that needed to be replaced. The part is
going to take 1-2 weeks to order...good thing it's only a TV for the
RV!

I have a couple of questions about this type of problem:

1. Are problems with the tuner common in a newer TV? Are HD tuners
more prone to failure? I've had a tuner go a couple of times on an
old tube TV before, but never on an LCD - and never on a NEW TV that
had a working tuner to begin with.

2. We mount the TV in our RV by the base of the TV, so the LCD screen
probably wriggles a bit during travel (since it can only be secured as
strongly as the display is secured is to the base). Most LCDs are
mounted via the screen itself using a wall-mount. I would expect wall-
mounts reduce the jiggle on the LCD display. I am curious if this
'jiggling" on our TV may have contributed to the LCD tuner failing?

Thanks!

Assuming it wasn't infant mortality, I would be concerned with vibration
first and voltage surges next. Can you wall mount it? The best way is a
bracket that takes advantage of at least four wide spaced mounting
points on the back of the panel. Secondly, make sure the cables don't
bounce around and flex the PC boards inside. Next, consider the
possibility that a voltage surge from the cable TV system might have
taken out the tuner. When you park at a random RV lot, you have to be
aware that the grounding for the power system and the cable TV might
have radically different potentials. Install a surge protector in your
RV and make sure it references to the AC protective ground system of
your RV and the supply provided by the park.

If you are running off a generator and your RV is floating, you have
another problem if there is a lightning strike as the surge will passs
through the TV and out the cable TV connection. Maybe having your own
satellite dish is safer?

Presuming the product is a known viable brand and parts are available the
have it repaired under the manufacturer's warrenty. Many of the off brand
products neither have support or parts available. When in motion select a
location and padding that will mitigate excessive vibration for the item.
