When it was very windy in victoria the other day the picture was pixaly, indicating a poor signal.
Same next day.
Today, new location ran the auto tune NO signal, others in the park are getting 3 or 4 channels
Sooo, i have just noticed when i plug the arial in there is a small spark.
Also dvd now not working.
1. is the spark when plugging in the arial normal, i have never seen this before.
2. Could i have a short some where or is just the tv buggered.
3. Has some thing buggered the tv
4. Any suggestions would be appreciated.
I dont have a ladder at this point.

Had a similar issue and it turned out to be the first aerial lead that went from the connection on the roof to the first junction on the aerial. The fittings had corroded
A new lead fixed the problem

Those aerials have a built-in amplifier to which 12V is supplied via the coax. I suspect the spark you see is due to there being a short in either the cable or the antenna. You can easily test the cable with an ohm meter and if you also use the ohm meter to measure the resistance of the antenna/amplifier you should see a reading of anything between 100k to 3M - you should not see a short.

Hi Mike, Thats my concern, if the fault is related to the amplifier. A tv is easy to replace. Not so the arial. I guess somehow the short could also come from the tv internally? We noticed last week that the inbuilt Dvd would not work unless the arial was plugged into the tv? Any idea?
If i buy a cheapo mulitmeter how should i test the arial?

There's a good chance you zapped something with a fair static charge if your antenna, mount and lead were on high winds.
Does the TV display anything (menu etc) ? Is the DVD connected to anything else but TV and power ?

Oops, didn't read your last post properly. Glad you're going again.

We were told to always fit the antenna plug and power plug to the tv before turning on the power. I ignored that advice a couple of tmes and each time blew the power supply fuse.
Hi, this could be tricky and will try to explain.
Cheap 22" digital tv with dvd player.
Wingard butterfly arial with amplifyer.
