No picture just av1


If the cat sat on the remote, it is likely it changed the tv to AV1. Just find the AV button on the remote and press it again and again. It should cycle through the different AV channels your TV has - my TV has 6 AVs, 2 HDMI and a PC channel so if yours is anything like mine, you may need to press several time to get back to your Sky/freesat/virgin box. Alternatively, some HDMI connected kit just needs turning off and on. That then sends a signal to the TV which changes the TV automatically. For example, my Blu-ray player does that.
Experience - I have a cat that sits on my remote and does the same thing!!

Cannot get channel 2 clearly


Normally grainy pictures are a result of poor ground connections, although usually for more than one channel. Check the cable connections first. Otherwise all I can suggest is to have the tuner replaced.

Not able to select HD on my Wii setup screen


Well see if it happens again, it may have been a one time thing. but try reconnecting the AV cables to the tv or change the picture settings on the wii setup options.
But this is important, is the picture grainy, or is there vertical black lines? if its black lines, i have the same problem and the only way to fix it is to send it to nintendo and theyll give u a new console. its due to overheating and the graphics card gets fried

Grainy picture


Greetings israelmaker,

In order to receive true high definition television, you will need a high definition cable box. Basic channels are going to look more grainy and not as clear overall even with an HD box, however you won't be able to view or decode the actual HD channels without a box.

In addtion, what type of cables are you using to hook up your existing box? This can have a substantial impact on the picture you see.

I hope some of this helps.

Mono setting?


What channel is it and when they tune in that channel, is the picture nice and clear or is it grainy and snowy before the screen goes blue? On some sets, if the signal is weak, the picture will go blue. This is called Blue Screen and is there so you do not see very poor, grainy and snowy pictures. Some sets will have an option in the menu to turn the blue screen off.
