Miscellaneous TVs, bus data is messed up, how to restore it?

The easiest way is to find a memory data of the same model, and replace it is solved!

The miscellaneous brand 25-inch Philips bus is messed up.

Find the data of this TV model and check it one by one, or replace the memory of the written data.

This miscellaneous LCD TV. If it's broken, hurry up and buy a new one! TVs nowadays are very cheap. A 55-inch 4K TV is about 1000 yuan. So. You don't need to change it, and you can't repair it.

How to solve the problem of misadjusting the bus of miscellaneous LCD TVs into gray screens,This you can only buy a new LCD TV。

According to your description, the direct cause of the gray screen failure of this machine should be that the LCD panel does not work, and the specific reasons include the logic board not working or working abnormally, etc., so see the following solution for details on this problem: This fault first measures whether the power supply voltage of the logic board circuit is normal (this voltage is provided by the motherboard circuit).

Well, if this miscellaneous LCD TV bus is mistaken into a gray screen, I think you can transfer this bus over, and see if it will be restored after being transferred.

This miscellaneous LCD TV is of very poor quality, so it is not recommended to use it.

Now the miscellaneous LCD screen can directly find after-sales satellites.

Replacing the motherboard should work.

Arrange Ye Qing's battery, LCD TV, communication, Jiaozuo, and Chen Huiping's words will be handed over.

Press the "Volume-" button on the TV first, reduce the volume to "00", then press the "Volume-" button on the TV and don't let go, and press the "Screen Display" button on the remote control at the same time, the character "S" is displayed on the screen, indicating that it has entered S mode. After adjustment, the remote control can exit S mode when the remote control is turned off, and the adjusted data is automatically stored. After entering S mode, press the "Screen Display" button on the remote control, the "S" character on the screen disappears, exit S mode, and then press the "Volume-" button on the TV set and do not let go, and press the "Screen Display" button on the remote control at the same time, you can enter D mode, and the character "D" is displayed in the upper right corner of the screen.

Press the "Standby" button on the remote control to turn off the D mode, and the adjusted data will be stored automatically.

First, adjust the TV program to news or advertising, then enter the bus, adjust the field hit or v-size item, if the field center is wrong, then adjust the v-cent or vp50, and you're done. Be careful not to adjust other items, and write down the original data before adjusting in case the adjustment is not used to revert.

But I have to explain,I have to use paper to record the original data before adjusting the bus,Once the adjustment is wrong,It's good to use it to restore the original,Now you've adjusted,And the original record has not been made,So it's a little hard to do,Unless there is another color TV of the same model,You can refer to it to adjust,The larger the number,The wider the line width,That's it。

Most of the miscellaneous TVs are 55L7 remote control boards, a few dollars a little, if there is no remote control, the bus cannot be adjusted. Poke the small hole under the remote control board with a toothpick to enter the bus. Or use the universal remote control, sometimes the bus will pop up when the universal remote control is set, but the universal sometimes depends on the character, sometimes the bus will pop up after a few clicks, and sometimes it can't get out.

Hehe, good luck.

In addition to looking at 863528C, we also need to see what the suffix is, and figure out what the electronic components can generally be matched to the sales department, and 55L7 is the most used.

Basically, all TVs must be coordinated by remote control to enter the bus.

Miscellaneous TVs entering the bus have little to do with the model brand. It has nothing to do with the picture tube, the LA76818A is not a CPU. The bus cannot be accessed without the remote control.

You have to find a remote control with the same model or matching, otherwise, no way.

Don't tell the truth when you report for repair, just say that it's like that as soon as you turn it on, the master doesn't dare to say that you are a man-made fault, lightning, poor power contact, and high-voltage ignition in the machine can also lead to such a failure.

According to your description, the direct cause of the gray screen failure of the machine should be that the LCD panel does not work, and the specific reasons include the logic board not working or working abnormally, etc., so see the following solution for details on this problem.

Answer: First of all, measure whether the power supply voltage of the logic inner board circuit is normal (this voltage is provided by the main board circuit).
