Static electricity and TV issue

Weird situation. If I'm close to my TV, not necessarily touching it and a static electricity spark goes off the TV screen goes blank and then comes back on. This is a new LG TV hanging on the wall and plugged into a grounded outlet. Last night I was putting a screw in the wall got close to black pipe running on the ceiling, spark, TV screen went blank and then came back on. This has happened several times in the past month. We do have a humidifier running is the room too. Any ideas on how to prevent this? Can't be good for the TV and don't want to have to replace it.

Re: Static electricity and TV issue

Touch something else to relieve the static buildup first. That happens to me every year up in my room. I always touch the metal smoke stack tube first before I touch any electronics. Back in the early 80's we would take out PCM's like that when we all would wear new shoes, ZAP them. The manager hated us.

I didn't touch the TV. I touched a black pipe on the ceiling that is about 4' from the TV. If memory serves me right one time I touched a metal fireplace screen I was removing to put wood on the fire and it blanked out. That was 8' or so away. Just plain weird. I understand if I directly touch the TV but.....

Re: Static electricity and TV issue

Sounds like a grounding issue in the electric circuit.
Could be the outlet the tv's plugged into.
Might try grounding the pipe to see if that helps as a temp measure.

Don't know how comfortable you are with checking in the breaker box.

What do I look for in the box? If I recall both my neutral and ground occupy the same buss bar. House was built and professionally wired in 1989.

Re: Static electricity and TV issue

Can you duplicate the conditions to make it happen ? If so put a piece of electrical tape over the remote control receive "eye" on the tv and see what happens.

Also make certain that the coax cable is grounded properly. You might have to even have your cable supplier check that. I know our outside box has a ground connection to the ground rod for our electric service.

I've seen where people have taken shortcuts and grounded phone and cable systems to the plumbing!

But, that wouldn't explain why any static discharge was causing the TV to blank - especially something like the fire place screen which isn't part of any electrical ground.

Raise the humidity. I noticed i can make the led light bulbs flash in the ceiling fan if i turn it on by using the pull chain. I think the humidity is around 25% when it happens. My house is hardly ever that dry, since it now rains every other day and its normally around 40%.

Re: Static electricity and TV issue

A code requirement here in Fl. when you upgrade an electrical panel is to add a special separate ground bar next to the electric service meter or panel if it's located outside for TV & cable grounding, I don't remember the name of this part since we don't do electrical work anymore since my friend that was the elec. lic. holder passed but I'm sure you could go to a local home depot or similar and ask, it Might cure the problem because to me it does sound like a grounding problem, and like already said make sure the receptacle it's plugged into is grounded, I also use Monster boxes on my sets

That's why I suggested blanking off the remote receiver. A spark could possibly be generating some infrared radiation and that is what most remotes use. It was just a thought.

And it's not as crazy as it sounds either. My stepfather had a special type of CFL bulb he put in a post lamp that was supposed to make reading a lot easier on the eyes. Turned out that when it was on, infrared remotes wouldn't work at all.

Re: Static electricity and TV issue

This reminds me of a funny incident from long ago.

Back when I was young and still at home, we had quite a few cats. A few of them had this habit of jumping on the TV table and walking in front of the screen. This would be the '80s, so no LCD flat screens back then. Trying to "shoo" the cats away was totally useless. So, my dad just resorted to momentarily turning the TV off , then back on, which caused the screen to release a lot of static. The cat sure felt that and would jump down to get away. After a few times, some of them learned to stop doing that.
