SOURCE: Volume and menu does not display

I had this problem on my Aquos (LC-46D62U). It was NOT a hardware problem. I recommend turning off the television. Next unplug the television for 5 to 10 seconds. This resets something for the television. Plug it back in and turn on the television. You should now be able to get your volume and other on-screen displays.

SOURCE: White screen only on Sanyo DP26648

Your reported symptoms are odd in that most failures are related to the primary power supply but that takes down both audio and video.
The backlight is obviously working (white screen) but it is no longer receiving any video information and this points to a failure of the logic (or the output of the power supply that services logic) used to control pixels on the screen.  Some screens have the majority of the control ICs actually mounted on the LCD assembly and because of very close pin distances used on dense ICs, they are often not replaceable by hand since they were installed by robotics.
I would first suspect (and hope for) the logic voltage output of the power supply to be the culprit. 
If any of you posters have had a repair done and received any kind of a detailed report (you should), would you be kind enough to post it back as a comment to this original message?

SOURCE: Turn tv on. green light solid display, no picture or sound

The flashing green light is likely indicative of a self-test failure, indicating the TV has detected some sort of internal fault. With no picture or sound, one strong suspect is the power supply. Flat-panel TV's have an internal DC power supply that converts the inbound AC current, and when these fail, or are unable to supply a minimum level of power to the set, it can behave as you describe, providing only enough power for the green light to illuminate.

Disconnect the television overnight. Remove the batteries from the remote as well. Tomorrow, put new batteries in the remote and plug the television in.

How do you get your xbox 360 to play, on a 65'' mitubishi projection tv,its connected but nothing comes on screen when i put a movie in just a blank screen and no sound,if i'm on a channel,the channel...


Hello

The Xbox 360 connects to a TV using either

- COMPONENT (red blue green for video, red and white for audio

- COMPOSITE (yellow for video, red and white for audio)

- HDMI

So, if your TV is on a "Channel", it is not on the correct input to view the Xbox 360.

Check the Xbox and verify which cables it is using to connect to the TV. When you find this, follow the cable to the back of the TV and find the input selection. It should be listed as the type and a number (i.e. HDMI 2, COMPONENT 1).

Have the Xbox on. Use the TV remote and use either the INPUT or the MENU options to change the input to the input that matches the port that the Xbox is connected to.

This should make the Xbox work.

When you are done with the Xbox, use the INPUT or MENU to change back to the tuner to watch TV.

Sharp tv has small black and white image in black and white and half screen pink


Sounds like your LCD Control board went bad. Very small chance it is your main board since you said you cant bring up a menu.

First thing to try would be to update the firmware. This link should take you to the LG support site where you can find the download and instructions you need to update your television. Look under drivers and software. Good luck.

My wii and Netflex is in black and white.


Access your TV's menu screen:
- be sure that your TV screen is expecting input from "AV" or "Video" - if you have the "S-Video" input setting selected, change it to "AV" or "Video"
This should bring the color back to your Wii experience.
