Tv or arial fault?

[englisharcher]

Our tv keeps playing up, we are unsure wether is is a faulty tv or arial.

We have the arial connected to the tv via a co-ax cable that goes fron the tv to an arial socket in the wall.

This setup has been working for 1 year, and started playing up about 2 weeks ago.

Sorry about the poor video, but this is what happens.

The aerial just delivers a signal, it doesn't do anything to it.

No - it's the quality of the picture after a wash in a well known brand of soap powder. ( said before spelling police come in ).


Seriously ,not a TV man, but I suspect Morningside is ( financially painfully for you) right.

The tube might have gone

As morningside has said, if the picture is that bright, (not just a dodgy pic you've posted) the TV is buggered.

It looks like you're suffering pixelation caused by a poor ariel signal when you click the picture and watch the video. (have you guys done that ;-) ?

You have a signal fault. Can be caused by aerial, cable fault, shorts on any of the connections. Another possibility is have you retuned the set recently as the tuner may of locked onto another transmitter that may have increased its power since last retune. You should have 115 SD channels or 119 channels if you have a Freeview full HD tv. If you have more channels then you have duplicated transmitter frequencies stored so try looking at channels 800 onwards to see if they work. If so you need to retune and eliminate the weak frequencies.

Joking aside, have you a set top x or a PVR/DVD/ VCR. If yes to one of these - try playing a recorded program and look for problems. If it don't misbehave then TV IS ok.

Yes the pixilation is the problem, the brightness is just how the video from my phone made it look.

The only other thing i can try would be connect the wifes laptop to the tv via HDMI, would that work to test it?

Opps, did not realise it was a video

Poor signal. Its alignment of/aerial or poor down coax.

Do you have amplifiers?

What does the signal strength and quality show?

The tv screen wouldn't cause that fault. It could be the tuner so playing an external source wouldn't really help. If you have a separate digi box then connecting that would give you a 2nd tuner to test if tv or not. Still a faulty picture would eliminate tv set. Really only true way of diagnosis is to put a meter on it and trace a reading from the aerial. If alls ok at top then we can work down through system to trace the fault.
Where abouts are you? If you're near Somerset/Dorset I can sort fault out as I own my own tv and aerial installation company
