Tcl TV FAQs

Explaining the odor in the use of new purchases: After the new machine generates heat during use, the insulating paint used in the engineering plastics, internal transformers, and electrical components of the housing will gradually volatilize some of its own volatile odors, similar to the newly-made furniture. In the same way, a certain odor will be emitted, which is normal. The odor will gradually decrease and disappear with time. It is recommended to keep the room ventilated.

After the machine has viewed or turned off the power supply, the machine itself emits a crisp “click” sound. Explanation: The machine is a cold-to-hot process during the viewing. After the power is turned off, the machine is a change from hot to cold. Process, at this time the phenomenon of thermal expansion and contraction of the machine, causing the chassis friction sound, is a normal phenomenon.

Obvious "click" sounds on the screen when turning on or off (appears when some of the machine's images are bright or dark)
Explanation: This sound is a high-voltage electrostatic sound and is normal. It is a kind of sound produced by high voltage electrostatic adsorption of surrounding particles (as if the weather is dry, combing the hair with a plastic comb will produce electrostatically similar hair sound). Since the high voltage of the CRT TV is changed from low to high or from high to low (high voltage has about 25KV) when the TV is turned on and off, the static sound generated at this time is most obvious.

Lights do not turn on Press the remote control standby button to turn on, it is recommended to use the panel button to boot, if you press the "channel +/-" button on the panel to boot, it may be the problem of the remote control.

Three (no light, no sound, no light on the screen)
A. First, check whether the power cable is connected properly. B. Check whether the power supply is connected to the power socket. C. Is the power switch on? If not, turn on the power switch.

Low-frequency "squeak" in the machine during operation
Explanation: This sound is the normal current vibration sound of the machine (also known as: hum). The sound comes from the power transformers inside the machine, the high voltage package, the deflection coils of the picture tube, and other high-power devices, all of which are normal sounds. Equivalent to the sound produced by fluorescent lamp ballasts, motors, etc.

There was a black screen in the program changing stage, the picture was still, and the explanation was directly skipped: The above three kinds of channel changing methods are all normal phenomena and are a setting method of the machine itself. If there is “Turntable standstill: ON/OFF” in the operation “Menu” option, you can change this item. In another case, the machine is set to be still at the change screen, but some channels are black when switching channels. This is also a normal phenomenon. This is mainly due to the non-standard signals, causing the synchronous recognition of the circuit signals to track errors, and recovering in a short time. This is a normal phenomenon (some machines appear to be unable to synchronize when part of the channel is being exchanged, and it is a normal phenomenon to recover in a short time).

It takes a few seconds for the color TV to boot up before the image is explained: In order to extend the service life of the picture tube, a soft start boot technique is particularly used. Its characteristic is: When you turn on the power of the color TV, do not reveal the picture within 3-5 seconds, the screen presents black, when the picture tube filament reaches the thermal steady state, the screen will gradually show the image. Can effectively shorten the aging time of the picture tube. The normal machine can boot within 15 seconds is within the normal range.

With a 16:9 screen color TV, people appear short and fat. (PDP, LCD easy to appear)
Explanation: This phenomenon is normal and is due to the 4:3 format of TV programs in China. When a 4:3 format signal is received on a 16:9 screen TV, the 16:9 screen TV will widen the 4:3 signal. , so the image will appear short, fat, if not used to adjust the screen ratio to other modes. Note: The 16:9 screen is the development trend of digital TV in the future. It is not recommended to watch in the 4:3 mode for a long time on the left and right screens, which may cause uneven brightness in the middle and on both sides of the screen.

Slightly tilted TV image Explanation: The reason for the slight tilting of the image is mainly due to the influence of environmental geomagnetic effects during the operation of the picture tube. This is a normal phenomenon. Basically, CRT high-definition televisions have “geomagnetic correction” functions, which can be adjusted and improved appropriately (specifically, the content of the product manual is subject to the standard). Ordinary TVs do not have a geomagnetic correction function. They can only adjust the TV viewing direction to try to improve.

TV can not stand for a long time, will not affect the life of the machine standby is a feature of the TV, is generally used in a short period of time to use the suspension, long-term standby not only there is a certain amount of power loss (although the function is small), The partial circuit of the power supply is in working condition for a long time and may also affect the service life. Standby operation is recommended to suspend use of the TV within 2 hours.

The TV image has a snowflake point to explain: A, signal problem (when the user uses an outdoor antenna, most channels of the program may appear "snowflake"; the use of closed-circuit signals may also appear in individual / several channels "snowflake"); B, frequency drift (Try "fine tune" or "manual search").

TV AV no image

There is noise on the TV
A. The signal is abnormal. B. The sound system is incorrect (usually set to DK). Note: If there is noise in individual stations, exclude the above possibility, can guide the fine-tuning adjustment or manually search for a test machine, if not a non-standard signal causes.

TV speakers without sound
A. The volume balance setting is incorrect (balance is adjusted to the middle value); B. External device wiring error (common audio cable access is not normal: only an audio cable, etc.); C. External device failure (suggestion: if conditions permit, change a TV to test external devices or change an external device to detect TV).

TV without color
A. The chromaticity is minimized (adjust the "image status" to standard and return to normal); B, the color system setting is incorrect (usually set to PAL or automatic); C, the external device wiring error (such as: the video line does not correspond Misuse of the brightness Y signal when the video connection, etc.); D, external equipment failure (Recommended: If conditions permit, you can change a TV to detect external devices or change an external device to detect TV). Note: If some channels have no color or color, they are caused by non-standard signals.

The CRT color electromagnetism picture tube TV displays the unusual local color of the screen under the action of the external magnetic field. It is relatively easy to recognize when a single color is displayed on a blue screen or a screen, which is a phenomenon unique to the display devices (color TVs, monitors, etc.) of kinescopes. The correct guide steps for the “automatic degaussing” of the CRT TV are as follows: 1. Turn off the power switch on the TV (or remove the power plug); 2. Remove the magnetic device around the TV (such as magnetic leakage speaker, magnetized drinking cup Etc.); 3, 15-30 minutes later, turn on (or turn on) the main power of the TV. If the magnetization has been eliminated, the TV will return to normal. "Automatic degaussing" explains: 1. Automatic degaussing uses demagnetization in the moment of starting. 2. Automatic degaussing is the unique operation of the display device after being “magnetized”. 3. CRT TVs are prone to “magnetization” in their use: For a long period of time, the TV is in a “standby” state, with a magnetic substance approaching the TV, and the TV being switched on in the on state.
