Troubleshooting and error codes
| Picture | Symptoms | Sound | Checks |
|---|---|---|---|
| Interference | Noisy Sound | Electrical Appliances Cars / Motorcycles Fluorescent light |
|
| Normal Picture | No Sound | Volume (Check whether the mute function has been activated on the remote control.) |
|
| ? | No Picture | No Sound | Not plugged into AC outlet Not switched on PICTURE and BRIGHTNESS/Volume setting (Check by pressing the power switch or stand-by button on the remote control.) |
| ? | No Picture | Normal Sound | If a signal with a non-applicable colour system format, or frequency is input, only the input terminal indication is displayed. Colour controls set at minimum level. (see page 22, 23) |
| No Colour | Normal Sound | COLOR SYSTEM (see page 35) | |
| No remote control operations can be performed. | Check whether the batteries have discharged completely and, if they have not, whether they were inserted properly. Check whether the remote control sensor is exposed to an outdoor light or a strong fluorescent light. Check whether the remote control designed specifically for use with the unit is being used. (The unit cannot be operated by any other remote control.) |

| A cracking sound is sometimes heard from the unit. | If there is nothing wrong with the picture or sound, this is the sound of the cabinet undergoing very slight contractions in response to changes in the room temperature. There are no adverse effects on the performance or other aspects. | ||
| The top or bottom of the picture on the screen is cut off when I use the zoom function. | Adjust the position of the picture on the screen. | ||
| Areas at the top and bottom of the screen where the image is missing appear when I use the zoom function. | When using a video software program (such as a cinema size program) with a screen wider than one in the 16:9 mode, blank areas separate from the images are formed at the top and bottom of the screen. | ||
| I can hear sounds coming from inside the unit. | When the power is turned on, a sound of the display panel being driven may be heard: This is normal and not indicative of malfunctioning. | ||
| The screen darkens slightly when bright pictures with minimal movements are shown. | The screen will darken slightly when photos, still images of a computer or other pictures with minimal movements are shown for an extended period. This is done to reduce after-image on the screen and the shortening of the screen's service life: It is normal and not indicative of malfunctioning. | ||
| It takes a while for the picture to appear. | The unit digitally processes the various signals in order to reproduce esthetically pleasing images. As such, it sometimes takes a few moments for the picture to appear when the power has been turned on, when the input has been switched or when the images for the main picture and sub picture on the two screens are swapped. | ||
| The edges of the images flicker. | Due to the characteristics of the system used to drive the panel, the edges may appear to flicker in the fast-moving parts of the images: This is normal and not indicative of malfunctioning. | ||
| The brightness on both sides of images in the 4:3 mode changes. | When viewing the side panels at the “BRIGHT” or “MID” setting, the brightness on both sides may change depending on the kind of program shown: This is normal and not indicative of malfunctioning. | ||
| Some parts of the screen do not light up. | The plasma display panel is manufactured using an extremely high level of precision technology, however, sometimes some parts of the screen may be missing picture elements or have luminous spots. This is not a malfunction. | ||
| After-images appear | Do not allow a still picture to be displayed for an extended period, as this can cause a permanent after-image to remain on the Plasma Display. Examples of still pictures include logos, video games, computer images, teletext and images displayed in 4:3 mode. Note: The permanent after-image on the Plasma Display resulting from fixed image use is not an operating defect and as such is not covered by the Warranty. This product is not designed to display fixed images for extended periods of time. |

| [for TH-42PHD7UY, TH-50PHD7UY] Whirring sounds can be heard from the display unit. |
The display unit is fitted with a cooling fan to dissipate heat generated during normal use. The whirring sound is caused by rotation of the fan and is not a malfunction. |
