SOURCE: LG 42PX3DCV 42 in.

Pixel misfiring (diffusion errors) are caused when the tv is not firing and erasing the pixels correctly. It can be caused by a number of things, usually a voltage or waveform is off somewhere. If you just bought the tv, return it and get another. If you are out of warrany, you can remove the back panel and run the tv to check the voltages. Don't touch the heatsinks! they're electrically hot and will zap you.. the voltages are labeled on the back of the plasma panel with a sticker. first check Vs and Va. sometimes you can check -Vy, Vset, Vscan and others if labeled on the board. If you have to adjust waveforms you need a very $$ o-scope and should get qualified technician to adjust. If a board is bad, its likely your power supply or Y-sustain pcb, and less likely your Z-sustain or contol (logic) board.

SOURCE: Color changed suddenly, no red, just green/yellow/blue

Sounds like the color wheel has gone bad and needs to be replaced. This is located behind the back panel.

SOURCE: My wii connection is black and white

You are connecting it into the wrong input. The Wii comes with a RCA cables that should go into the Video (composite) input that has yellow, red, and white. The component input will not work with the RCA cable input. Plug your Wii into Video1 and you should get the right colors. There should be another HDMI on the side of your TV, there are inputs located both on the back and side of the TV for your convience.

Wrong connection. Hook up the component output from DVD player or Wii to TV component input using component cable(red, green and blue plug)

I got a Samsung 1080i television, but when i connect my dvd player to the back, it does not pick it up. i also tried connecting a tv freeway antenna and that did not work either.


Check the input selector. If it is not set to use the source signal type, the set won't pickuup any signal. If the source signal is antenna, you shoud select antenna as input selector. If the source signal is AV, you shoud select AV in the input selection. Press the input button at the remote controller, and do the needy.

depends on the output from Foxtel

Suggest you google these connection interface types and work out what is the output types
if rca then use av input on tv
is hdmi then use hdmi input on tv
then use select input source on tv to switch to whatever you used.

How do I watch normal tv on my audiosonic television ?


That depends upon which source your "normal" TV is connected. If you have a cable box using a coax cable, then you will either select the DTV source if the cable box uses digital output or a digital over-the-air antenna, and ATV source if the box is using analog signals or if you are using an analog over-the-airwaves antenna. If you are using a cable box but have an HDMI cable connecting it to the set, then you need to choose HDMI1 or 2 as appropriate. If you have a box that uses the red-black-yellow RCA cables, then select the AV input. Remember that for ATV and DTV inputs from a cable box, you usually have to tune the set to either channel 3 or 4 and use the box to change the channels.

How do I convert from DVD to cable?


Do you wish to get signals from DVD player to TV? If so, the antenna connection won't work. You should use AV connection, using AV cable, and have to select the input to TV as AV. Contact any service technician. Gopakumar Gopalan Google

How do i change the input


The 27" TV uses the same instructions as the 20", and I found the manual for you at the link below. Answering your question directly, here is the section of the instructions about changing input:
-----
Changing the TV's Input Normally, your TV displays the signal coming through the antenna terminal. However, if you've connected another component to your TV(such as a VCR & DVD) using the Video/Audio input,you will want to be able to view the signal from the component.To do this, you will need to switch from the ' TV ' input to the 'AV1-AV3, CVI' Input, as follows. 1 With the TV on, press the MENU button twice, then " Set-Up " menu will appear. 2 Use the WCHV buttons to select " Input ". 3 Press the CVOLB buttons to change the input source from ' TV ' to 'AV1, AV2, AV3, CVI'. 4 Wait 20 seconds, or press DISPLAY button or MENU button to return to normal TV viewing. * CVI means the Component Video Input (Y/ PB/ PR) from the DVD player etc.* Users can also select these input modes with the TV/AV button or the INPUT button on theremote controller. * On the AV1 mode , if you connect the S-VHS jack to your TV, "AV1" is changed to "S-VIDEO".

How do i connect the cables from antenna to set top box to dvd player to tv what cable goes where?


The antenna goes in the box in it's connector. Then the box and the player will have to be separately connected to the tv using 2 AV cables like

To view them you just power them up and select them from the AV/source/input menu of the tv.

I clicked a button by accident last night and now my Vizio tv reads no signal and a small display in the top right corner reads AV. How can I get my tv to read cable signals again??


What input is the cable connected to? (Coax antenna In, component video, composite video)

Look on the remote or the TV itself for a button marked Source or Input. Press this. For some TVs, use the up/down arrows to select the input to which your cable is connected. (TV = coax) On other models, you may need to press the Source button several times to advance between inputs. (I'm assuming you have a remote that works for this feature on the TV; otherwise, use the TV button.)

I hope this helps.

Cindy Wells
(common modern TV setup: VCR on AV1, DVD player on Component 1, PC to the HDMI/DVI and coax to the antenna in. The source button is needed.)
