Samsung monitor warning

[W5DC]

Last night, I purchased a new Samsung 27 inch analog/digital/hdmi monitor from Costco.  It worked well until I transmitted with my K3 and vertical dipoles that are close to the ham shack but turned off whenever I would transmit with 40 watts or more.  I tried adding ferrite chokes to the signal and power leads too no avail.  I returned it to Costco this morning and bought a similar but smaller monitor made by LG and it works at the full K3 power of 100 watts with no problem no ferrites neaded.

I have a Samsung 2494HM monitor and occasionally transmit with a Ten Tec Titan III amp at 1Kw (I never run it full-bore). I have not had any issues with my monitor. I bought it from a company called "tech-for-less" on-line for $179.00 on sale. I operate from 160M through 440MHz, and have not discovered any problems at my installation. -WY3X

I have a Samsung T260HD monitor that also turns off when I run more than several hundred watts.  The problem still occurs with the video cable disconnected from the monitor and with the monitor powered from a UPS to isolate it from the AC line.  I suspect that RF is directly getting into the capacitive touch switches on the monitor.

My neighbour just paid me a visit.  He said that every time I've been on my HF radio, it causes their Samsung television to turn on and off.  Yes, Samsung.  We have an LG and have never had this problem.

Not good.  To make the problem even more complicated, my neighbour also happens to me my landlord.  Super nice guy.  But obviously I can't keep playing on HF with this problem taking place.  All I have is 100 watts going into a vertical whip antenna.  His TV is at least 20 meters away from the antenna.  What can I do???

Dallin - AD1Z,

The touch controls on some brands of monitors and televisions can be a pain. Just to set things straight, your neighbor's television and the owner's manual that comes with it will have a Part 15 label that reads:

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

(1) This device may not cause harmful interference, and

(2) This device must accept any interference received, including interference that may cause undesired operation.

It's important for your neighbor to understand that he needs to discuss this with Samsung and that your role is to simply provide Samsung with information about your operating parameters when the television malfunctions. Assuming that your station is operating as it should (since your LG seems content then it's likely your station is functioning correctly) it's important for all concerned to understand that you aren't responsible for whatever appliances your neighbors wander out of Walmart with. Of course, since he's your landlord, it's a fine line you're walking there!

Just for the record, my station computer runs a Samsung Synchmaster SA300 with touch controls and it doesn't flinch when I run the full legal limit on any HF band. I have a Samsung LN83296D HDTV sitting 6 inches from my pair of 3-500's and it doesn't flinch either. You can see a picture of them in my QRZ profile. I have to assume that variables in certain installations are causing the RF sensitivity that some have experienced. At any rate, your neighbor's problem is with Samsung. Offer to help him with information when he calls their technical support number.

There have been multiple threads here, and the common themes are "Samsung" and "touch sensor". I had a big problem with my Samsung C7000 TV until the service tech came to my house and disconnected the touch sensors entirely. My shack and antennas are at least 50 feet away from my TV, and in a different building....

LG seems to be RF friendly, Samsungs apparently are not. I keep hearing this same theme over and over on this forum....

I think that on the Samsungs, the model has a lot to do with it. I have a higher end Samsung with touch controls, No Problem. LG no problems. DirecTV new model DVR receiver with touch controls, goes crazy when I transmit. Older DireCTV DVR receiver with real push button switches, No Problem.

Thanks to Mike W7VO's response, I disabled the sensor board on my T260HD and it no longer turns off everytime I transmit.  Been looking for a resolution to this for a long time and had recently decided to try to find a different TV/monitor that would work.  One last review of this forum and I found the answer.  Since I always use the TV remote and  never use the on/off sensor function, this is the perfect answer!

What can you do? The simple way around this is to reduce power until the problem goes away and operate a bit below that power.

A better way for you would be to order a good number of snap-on RF chokes and add them to your landlord's TV. I'd buy 100-200 dollars worth of chokes from DX Engineering and be generous with them. Try to fix the problem in one visit. The landlord's patience may wear thin quickly if you take hours or days to fix the problem.

A combination of ferrites and reducing power might be the solution that works for both of you.

If your neighbor's Samsung TV has the touch-sensor type on/off feature, all the ferrite in the world won't help - been there, done that.  RF is effecting the sensor board and the only way to stop it is to disable that feature as I mentioned in my earlier post.  I tried everything I could think of over the past year and finally gave up until I saw Mike's post regarding the Samsung tech's solution.
