How much does it cost to repair an HD LCD TV?
In HD LCD TV, there are screen flicker, screen flicker, black screen, freeze, etc. Users will consider a question, is there a standard for maintenance costs and practices? My answer to readers is that there is no standard.
In recent years, with the development of network HD LCD TV, HD LCD TV, building 3G network HD LCD TV and vehicle 3G network HD LCD TV have been widely used in various industries, and efficient digital office and digital monitoring have become the biggest features. If the power amplifier of the HD LCD TV driver board is abnormal, replace the driver board; if the speaker is abnormal, please replace it. In addition, the video believes that if the connection cable of the general high-definition LCD TV speaker is not firmly connected, the Z is easy to fall off. If it comes off, solder it with a soldering iron. If the speakers make a lot of noise, the HD LCD TV driver board will be damaged. Replace the driver board immediately.
1. If the machine has been working normally, and this happens suddenly, it means that the LCD screen in the high-definition LCD TV has a working failure. The solution is to find an LCD high-definition LCD TV supplier to repair or pay for a new LCD screen during the warranty period. The after-sales cost system of each enterprise is different, so there is no standard.
2. If this happens to the machine due to some special circumstances, it is necessary to deal with the problem of returning to the factory at any time according to the situation and the size of the equipment.
3. The occurrence of the black screen problem, the signal operation of the plug-in main board, and the normal power supply of the power board can be evaluated and checked by looking at the indicator lights or whether the main board is working.
4. Check whether the power of the smart HD LCD TV is connected, and whether the wires are off or loose. If the power supply is flowing, first check whether there is power on the decoder board, then check whether the driver board of the HD LCD TV has power, check whether the high-voltage rod is powered on, and check whether the LCD screen is powered on. Any discrepancy indicates that the fault is with the part and informs the manufacturer to replace the part. Generally speaking, the possibility of power loss is the greatest.
