The most common failure of home-based televisions + the immediate means of checking/maintenance, by phenomenon, is simple and practical so that most problems can be solved first。
I. Turning off is not responding (totally no light, no start)
1. Electricity first
- is there electricity in the plug? Try a different plug/plug。
- is the power line tight? Is it broken。
2. State of indicator lamps
- lights are not on: power panels, power lines, plugs。
- lights are on but not on: may be the main panel, keyboard leaks, remote controls fail。
3. Simple processing - power outages 5 minutes before transmission (forced restart)。
- no remote control, press body physics button。
Ii. Sound without image 1. Backlights are not on (most commonly)
- the light is tilted to the screen and can see a dim image of the back light。
2. Handling
- re-launch, change the signal source (top box/ucd)。
- still silent, mostly hardware failure, requiring maintenance to replace lights or drives。
Iii. Imaging without sound
1. Basic screening - did you press the silence
- zero
- did the audio output cut to the outside speaker/bluetooth
Signal problems - try changing the roof box/u disk to determine whether it is television or a signal source。
3. Software/hardware
- restore the plant set-up. - still silent on the horn or the main panel audio circuit failure。
Iv. Screen screens, flash screens, stripes, vertical lines 1. Flowers/blinks - first change of signal source (exclusion roof box)。
- rehabilitation of plants and upgrading of systems。
2. Fixed vertical/wire/colour
- basically the screen itself, the screen, the logboard failure。
- this usually involves professional maintenance, screens are expensive, and the old machine proposes to switch to television。
V. Automatic shutdown, automatic rebooting, black screen at random 1. Dispersion
- back vent blocked, overheated, cleaning up dust, not too close to the wall。
Power problem - power plate capacitor drum packs, output instability 3. Software issues - system card death, app conflict rehabilitation。
Vi. Remote control failure
1. Replacement of new batteries (a lot of people ignore)。
The head infrared light of the remote control was blocked/dirty. 3. Cell phone camera presses the remote control to see if there is a purple flash:
- there's flashing television reception head problems。
- no flashing remote control bad。
Network/wifi not connected, carton
1. Restart router + restart television。
2. Forget wifi reconnected。
3. System carden:
- unmount without app, clear the memory. - restore the plant set-up。
Security alerts (important)
- unprofessionally, do not remove the backcap, which contains high-voltage electric caps, which can still be electrocuted after the power has been cut。
- screens, backlights, main panel failure, old tv is new atten compared to adjustment。
