Skyworth TV failure,Skyworth TV failure

Isn't it "urgent". Urgent... If the sound is very high-pitched, it is usually caused by the loosening of the inductor in line scanning. Just find that dropping point 502 glue.

The line frequency is unstable, the reverse path capacitor or the problem of the high voltage pack.

This range is relatively large, you have to see if the main power supply is normal first!! You said the possibility.

There is a malfunction! Power, line, field, mid-amplification, and CPU parts are all possible!!

Friend,To be precise, your TV is [your power filter capacitor breakdown,It belongs to the high-voltage components,But,The high-voltage package must not be broken] If it is repaired, it is not considered manual cost, and the light parts are 10....15 yuan, how much is specific, depending on the quality of the maintenance master.

Divided into natural faults and man-made faults: natural faults are divided into original component aging and damage faults, lightning damage faults, etc.

Man-made faults are divided into man-made hardware damage, man-made software damage faults.

The mid-cycle frequency inside is wrong.

In the switching power supply part, the parameters of individual components are changed. The focus is on capacitance. Appropriately reduce the AC input voltage, yes.

to reduce or eliminate noise.

If the sound is turned down and the harsh sound disappears, it is caused by the horn being loose. Just fix it.

There is also a problem with the TV itself, and if the treble cannot be amplified linearly, it will produce distortion when the treble is raised. A harsh sound is also produced.

Kiss the above is the solution to the common faults of Skyworth pants TV,If the above methods cannot solve the problem,It is recommended to contact Skyworth Electric Sun and STONKAM after-sales service center for maintenance or branches。

Here are some common Skyworth TV failures and how to fix them:1Won't turn on:

If the Skyworth TV can't be turned on,First check whether the TV has been plugged in with a power cord,And whether the power socket is normal。 At the same time, you can also try pressing the switch button on the remote control or the switch button on the TV body to see if it can turn on. If none of the above operations can solve the problem, it is recommended to contact after-sales service.

2.The display screen has no signal or black screen:If there is no signal or black screen on Skyworth TV,You can try to solve it by the following methods:

Check whether the signal source is connected normally; Wild cover Check whether the connection such as HDMI cable or VGA cable is loose or damaged; Try adjusting the input source using the keys on the remote control or TV. 3.Overly obvious backlight leaks or vignetting:

This may be because there is a problem with the backlight film or homogeneous plate of Skyworth TV. At this time, it is necessary to contact the after-sales service for a more imitation replacement. 4.

5.Abnormal sound:If the sound of Skyworth TV is abnormal,You can try to check whether the volume is adjusted to the maximum,Whether Dana has turned off the mute mode,And whether there are other external factors that interfere with the sound of the TV, etc。

In short,If you encounter the problem of Skyworth TV,It is recommended to check one by one according to the above methods,If it still can't solve the problem,You can contact Skyworth TV after-sales service。

Hello Kiss I am happy to answer for you: 1. No power, no light, no 5V: faulty component ZD603 (30V).

ic601(srt6556) ;Component burn-out open circuit or breakdown; The failure rate is 60%. 2. Do not open the Li machine, the light is not on, and there is no 5V for eliminating the front: the faulty component D607 (CW7805); This component is a 5V regulated output block, damaged or poor performance, and the power board has no 5V output; The failure rate is 40%.

3. The output voltage of 5V and 16V is low: the fault Yuanxiaoqiao delay part IC603 (TL431); This component is damaged or has poor performance, and the power strip output voltage of 5V and 16V is too low; The failure rate is 80%.

4. Indicator light flashing or dim: faulty component Q609 (A1013).q610(c1815) ;This component is a standby switching circuit, which will cause the 5V output to be insufficient, the indicator light will not turn on, or the boot will be normal but cannot be turned on after standby. The failure rate is 60%.

5. Abnormal sound of power supply in the state of the infiltration machine: the spine barrier component R608R605C606; Connect R608 to one end of AC and solder to the positive pole of C00220UF 450V capacitor, change R605 to C606 to 1UF 50V; The failure rate is 80%. 6. The light does not light up if it is not turned on

Faulty components V601 (varistor), F601 (fuse); Lightning strikes or high mains voltage will cause the V601 varistor to break down and the F601 to melt, so that the power supply will not work without power supply: the failure rate is 70%. I hope it can help you and I wish you a happy life.
