Tips to avoid problems with Panasonic screens
- Do not put the plug of the Panasonic screen into the electricity, except when using the device, because the electricity inside the device does not fluctuate.
- The screen should be kept in a fixed place away from movement and children, and it is better to place the screen in a high place.
- The internal panel (Panel) is considered the most expensive price on the screen, so when it is damaged, the Panasonic maintenance center cannot repair it, because it is equal to 80% of the price of the original device, so it is preferable after any source that exposes it to exposure to shocks or breakage.
- Never clean the Panasonic screen with any liquids, as this will damage the electrical circuits in the screen that is located at the bottom. It is best to wipe the screen with dry tissues of fine dust only.
- If you want to operate the screen in HD mode, it is preferable to turn it on only if the channel supports the mode, because in this mode all the T-CON card’s RAM is used, and if the channel does not support it, the vision will never improve and there will be no difference.
- While operating the Panasonic screen, it is absolutely not recommended to put cotton or plastic furniture on the screen, and you should avoid placing any decorative antiques because this prevents the device from being ventilated and works to muffle the heat inside it, which leads to many problems and damages electrical circuits as the least possibility.
- It is preferable to use the best connections for audio and video playback because poor connections do not produce clear sound and sometimes lead to blurring of vision.
- It is better when you want to update the device, to use the maintenance engineers team from Panasonic agency, rather than causing damage to the screen because wrong updates cause the driver bot to be disabled.
- Any small malfunction should occur immediately with the customer service team, because the Panasonic screen repair center provides a customer consultation service, to obtain immediate support instead of using the device and the exacerbation of the malfunction and the cost to a greater proportion.
- The device must be placed in a safe place away from the source of heat from the sun, because it causes burning of the internal Panasonic screen, and it is also preferable not to place any liquids close to the TV screen.
