Question about Sharp Aquos LC-46D62U 46 in. LCD HDTV
I have a 3 month old aquos 46d64u LCD TV which is having a weird problem with the standard av inputs. Occasionally when turning on a gaming system (Wii and XBox), the audio will come through fine, but the video will just be a series of random colored patterns that flash on the screen. Both systems produced the same garble pattern, but through different av ports.
This has happened twice, and the second time turning the TV off and back on resolved the issue (don't know what fixed it the first time, tried too many things without knowing which one worked).
Both times this happened, one of the consoles was left on accidentally for a few hours, while the set was on another input. Could this have been the cause?
You know, I've had two repair instances regarding this particular model line (D64U) where there were problems with only the analog inputs (such as the component/composite).... but with no problem with the HDMI inputs.
Replacing the Main Board fixed these TV's. Since both the Xbox and the Wii present the same problem on two separate inputs, this leads me to believe you most likely have a defective Main Board. If your TV is still under warranty, I suggest calling Sharp to locate your local authorized service center.
