We have 2019 Int'l Signature 28 RBQ, if we have the TV on (using Ant) and turn on our bathroom light we loose the TV signal... things that make you go hmmmm.

On all channels or just one?

Mattirs · 08-05-2019, 07:37 AM

There a thread here about this happening when the overhead LED lights are turned on, but I could not find it.
The reason I was looking, I just discovered last night if I run the LEDs on full it happens on the higher channels but all is fine when the lights are on the lowest setting.

I wonder if it shares power with the TV antenna booster? Either putting RF noise into the line, or somehow shorting the line.

I loose all channels.

Hi

In all likelihood it is simply an RFI issue. The LED lights have a switching regulator in them. It produces interference. Depending on just how the wires are run and the minute construction details of this or that light ... you do or don't have a problem.

Same thing happens to us when we turn on bathroom or shower fans

Both our 2017 23D (recently sold) and our 2019 FC 25 have the same issue. Great TV reception and many channels. Turn on the overhead LED's, and poof, no reception. We just consider it the nature of the beast. We have a nice small table lamp with a regular 40 watt bulb on the table that we use when watching regular TV. The LED lights do not effect anything when watching Netflix through a Fire Stick.

There may be some kind of cure for this condition, but we are not interested in rewiring the Airstream to get reception with the LED lights.

A filter designed to keep engine noise out of the car stereo might work to kill the interference at the light. The bad news is one would have to be installed at each interfering light.
Something like this might work (but it might not):

Depending on its design, it might work better on an interfering light if installed backwards. In the stereo application the noise is on the power line and the stereo line is clean. In the light application the noise is on the load side and you want the battery side clean.

Quick solution: Don't watch TV in the bathroom - except in the dark.

Have the same TV signal problem when we charge a phone or pad with the USB charger upfront near the radio. Seems like the signal is very sensitive to any electromagnetic interference. But then, if it was like home, it wouldn't be glamping!

You have a "loose" tv signal as in it's not tight? Or, did you "lose" the signal?

2017 25a, Air TV works with lights on in bathroom, but scrambles when bathroom vent fan is turned on.

Generally, the little DC motors in the vents are "dirty" in the sense that they put out all kinds of radio frequency interference (aforementioned RFI). Not much you can do about it.

HHPJ · 08-05-2019, 06:11 PM

We make sure now to go to the bathroom before watching a good program...! Lol

I tapped into the power behind the antenna booster and I can tell you it's all kinda weird. I had to pull every fuse but still the little booster light was lit. Might be a hidden capacitor somewhere, or maybe wired direct to the battery (another phantom power draw?) but it was strange for sure.

I have heard that some folks who have retrofitted older trailers to LED lights have had similar issues. What follows is that these problems were often caused by the purchase of cheap LED lights that gave off lots of "noise" when in use.

But, this is a new trailer directly from Airstream and I am assuming that the owner has not changed out any bulbs. To think that this very expensive trailer will not allow you to watch television and have a ceiling light is preposterous. I would be at the dealer ASAP. If they say that it is just "the nature of the beast" I would then return with a television camera crew and a lawyer. This is totally unacceptable. Am I off base here?

2019 FC 25FB when we turn on TV and suction fan in shower all channels get fuzzy.

oldenavy · 08-06-2019, 08:34 AM

Does your bathroom light have a dimmer on it? LED dimmers use Pulse-Width Modulation (PWM) which essentially turns the power to the light off & on very rapidly (too fast for the eye to see). If not filtered properly that could cause interference, just like the cheap brush-type motors in the vent fans.

As a test: Try plugging the TV into a different outlet in the trailer, or better yet not through the trailer electrical system at all via an extension cord. If the problem goes away, it's a conducted emission problem that you may be able to get a filter to fix. If you still have the problem, it's likely a radiated noise issue which is much harder to fix.

I contacted Airstream Customer Service and the responded fairly quickly. However their response was concerning. The person responding indicated that they are aware that they are aware of the problem but have no fix for the situation. The person then asked if there was anything else they could help with. There was no indication that they were going to do anything to correct the issue going forward.

This is very concerning from a perspective that they are aware of a defective product but continue to sell it knowing this. You would think that this would violate the Consumers Protection Act.

If I sell my house, by law I have to disclose any defect that I am aware of, if not I could be sued and responsible of the cost of the repair.
