Service (engineering) menu on LG TVs

Archivarius “04 Sep 2014, 23:03

Each LG brand has a service (or, in another way, engineering) menu, with which you can change various TB parameters. Service menu (cm) is about the same as BIOS in a personal computer. The parameters, the values ​​of which can be changed, are responsible for both the operation of the TV software and the functioning of individual hardware components-backlight, display, audio/video modules, power supply systems, etc.D.

Using the service menu, you can make serious changes in the work of TB, so you can’t get into it just like that (read about the ways to enter cm below).

Using the engineering menu in the majority of TB LG, you can change the following:

  • Image spectrum. Most often, such settings are used to restore a normal image, which can be lost for various reasons. For example, the image can become excessive reddish or greenish.
  • Screen parameters. In a separate window, you can increase or reduce the scale of the image. If you accidentally modified the settings and the image is cut off from above, from below or from the side, this function can also help solve the problem and return everything to your own circles.
  • Sound. If you are not satisfied with the reaction of the sound panel to the buttons (too much/weak decrease or increased sound when pressing on “-“/””), you can adjust this to the menu. Various effects are immediately configured. echo, increased acoustics, etc.D.You can configure TB even in such a way that when the maximum volume is turned on, the sound will be practically not heard. This will have to come in handy, for example, when there is a small child in the house.
  • functions TV. For example, you can configure the parameters of Smart TV and smart television.
  • Full discharge. TV service menu may be required to return to factory settings. This is most often required with unstable operation of the device, freezing, or failures.

Currently, you can get to the service menu on LG TVs in one of the following ways:

  • use a special service remote control (you can buy on AliExpress);
  • use the universal remote control type “One for All” (USB Changer, URC7120, URC-7556, Oneforall Kameleon, Philips SRU7140, Tiantianyong TV-139F);
  • Use a phone or smartphone with an IR port:

LG LED TV Entrance to the service menu

If done from the battery (meaning?), it is better to use a lithium battery.The scheme is still not suitable, large consumption without a signal. Jester: 1.R1-10KOM?The low input resistance of the cascade on Q1 has not been taken into account.At such a frequency of the front, it will not be filled with, and there will be no distortion-symmetry. 2.C2/R3-read the constant of this chain and the meaning of these nominal nominal in this cascade?(precisely the nominal nominal, not this chain) 3.R2-ethical resistor is set half of the power on R4, on different transistors this value will be very different.The temperature of the medium will also contribute to this. 4.The output cascade of course turned out, really working.(according to the type of amplifier on the OS with a short output). But there is no sense in such bells and whistles, again, the input resistance is quite low in such an inclusion (the amplification is good), and this is again to the issue of the need for the first cascade on Q1. This is that such an exit does not need a “harmful” cascade on Q1, you can simply give a signal to R5.It will be even better. Although what could be better than a service remote control.Or “on pic12f629” well done!
