My Nava 13 inch tv/dvd the screen is constantly flickering. It worked great until i moved recently. Why is my screen constantly flickering - what can I do to make it stop?

It could be interference from something, so make sure there are no wires near the aerial lead.

Give it a sharp tap on the side or top.

Buy a new 46 inch Samsung!

This is an unknown make!

Noticable flickering when viewing dark images.

Hello, I too experience this exact same problem. In my opinion, any television under 2 grand is probably going to have some slight imperfection as this; I have tried a few different ones myself. To some, it would appear to only be a minor annoyance, but to those who truly can distinguish a good quality picture between a bad one, or to those people, such as myself, who would find something like this to be unacceptable, this is a disheartening situation.
My friend, I have tried many different settings to see which ones might resolve this issue with the blacks in the picture, or at least reduce it to a barely noticeable level and I have found that when I select the CUSTOM picture mode, reduce the contrast to about 60, turn up the brightness to 62, turn OFF blur reduction,x/v/ color on, CATS on, MPEG NR ON, turn Dark level to LIGHT(this is important) add a little bit of extra color for ex. 52, and sharpness to 75, that this produces a pleasing to the eye performance when watching blu ray movies and dvd's. The flickering is reduced to almost nothing, and the picture quality actually appears sharper and more ethereal in certain ways.
The downside to this is that you are lacking some true depth in the picture's darks, but after your eyes adjust and you are watching a good quality movie, you will notice that there still sort of is enough darks there to compensate. Further fine tuning may produce even better results, jsut have to keep playing around with it. But I am now convinced after hearing somebody come forward with the same exact problem i'm having on the same tv, that it is not a defect but just an imperfection that you sometimes have to deal with when you don't spend like 5 grand on a tv. Good luck and happy viewing!

Flickering - Toshiba 62HMX84

it could be as simple as the tv feeding back on itself in a dark room.
it is adjusting the light level because of what it sees ambient in the room.
turn on a light near the tv and see if it stays constant now.

Repair of digital camera

If you see all black in the viewfinder something bad has happened to the lens. It could be stuck, tilted, etc.

It will need to be taken apart and serviced by a trained technician.
