Electricity usage of an LCD/LED Display or TV Screen. The power consumption of computer or tv displays vary significantly based on the display technology used, manufacturer and build quality, the size of the screen, what the display is showing (static versus moving images), brightness of the screen and if power saving settings are activated.
There are many ways an LCD monitor can go wrong, but the diagnostics above cover the most common problems. Try the suggested fix that matches your problem first. If your problem is not described above, or if the monitor still won't work after the attempted fix, consider these issues as well:![Lcd Lcd](https://cdn.myshoptet.com/usr/www.eljo.cz/user/shop/big/11295_lg-gsj761pztz-skrabanec-natuknuti.jpg?5cd20383)
- If the picture responds to input but displays a messy image, such as jumbled multicolored squares, the AV (audio visual) board may be damaged. This is usually a rectangular circuit board located near the audio and visual cables. Replace obviously damaged parts using a soldering iron, or order a replacement board and carefully install it to the same screws and ribbon cables.
- The main control buttons may be faulty. Clean them with a metal cleaner, or jostle to attach a loose connection. If necessary, locate the circuit board they are attached to and re-solder any broken connections.
- Check input cables for damage, or try other cables of the same type. If necessary, inspect the circuit board they are attached to and re-solder damaged connections.
