Question

Black flickering Horizontal line on my tv

Good evening.

Could one of you tech savvy guys from Cnet or any of it's users give me some advice?

This is my dilemma! I have a permanent horizontal Black line on the bottom half of my tv 2 milimetres from the bezel, it alternatively flickers every 3 seconds to a 2nd line appearing around 5 centimetres above the permanent line, this 2nd line stays there for around 3 seconds then disappears for 3 seconds repeatedly, it seems that the intermittent line that appears , it's the same amount of time each time, so it's got the same frequency to the time the 2nd line appears. in between the 2 lines there's a very faint greyness when there's a white background, although when it's got my tv guide on I've noticed the writing in the guide becomes distorted for 3 seconds then ok for 3 seconds alternatively.

Could anyone provide me with a possible solution to this dilemma?

Kind regards

Col

Clarification Request
Is this only when it's on your cable TV box?

Please tell more. Such as is it only on the cable box or on antenna and other inputs. Tell the make, model and age too.

Hello Proffitt

Hello Proffitt.

Thank you for your reply

The lines are there no matter whether it's normal tv, android box or dvd, so it's definately the tv at fault.

The make and model are Goodmans 50" G50238Dvbt2-LED Ver3, I'm unsure of the age.

Any advice given would be greatly appreciated

Regards

Col

Just back from lunch and thought a bit more.

Before I go on, what follows is to be taken as if you are an electrician or technician and familiar with safe practices. I am omitting all safe practices here with this forward.

Let's say you are going to get a new set and repairs exceed the value of the set or replacement. Given that I would at least get it onto the work bench to do a very entry level bit of work. What is that? Remove power, open up the back and gently unplug and plug every connection back in.

There's a slight chance this is a board or cable connection issue. Slight but worth the work if the old set's next stop is the recycle center.

Very good advice

Hello Proffitt

I was thinking the same.

If the lines get any worse that's gonna be my next port of call.

I thought the same as when I have any parties, I tend to crank the music up, to the point where my speakers actually vibrate, so I have surmised over time, with the vibrations from the speakers, that it could of dislodged a few wires, Am I correct in thinking they're usually at the top part of the tv the plugs?

I do appreciate your advice, you're a top bloke

Answer
Try other hdmi ports, cables and modes

Besides that, there is not much else to try.

Thanks for your response Pepe7

I've tried the hdmi ports, also the ariel, i've flicked it on and off again at the power source (unplugged), nothing seems to rectify it

In that case...

...you will need a new HDTV
