Please pay attention to all members! Yesterday, I picked up a TCL L40F3800A advertising machine, which only played advertisements and watch TVs on TV interfaces. Other functions were completely hidden! The user asks for a password and turns on the signal source to watch the AV cable TV. At that time, the user was asked to take the remote control of the machine and prepare to find an answer on the network to solve the problem. Can be tossed all night, there is no member on the network to open the answer! I downloaded a similar firmware, but I can't upgrade it! (In fact, there is no need to install the program to upgrade)
Finally, there is no way, I have to pay 30 yuan, go to someone to buy a password! (The so-called password, just how to enter this type of TV into the bus to call this option to change the settings!) Now this process is open, I hope that members will encounter this situation in the future, do not spend money to buy Password! If you can use it, please be satisfied with it!
One: prepare the original remote control, turn on the TV, press the menu button with the remote control, adjust to the setting item, call up the display item, and then adjust to the advanced setting item; move to the contrast, then use the remote control to quickly input the so-called password. :9705
Two: At this time, the bus adjustment item will appear immediately on the TV screen. Use the remote control up and down program keys to move down slowly, and move to the penultimate item: Advert MODE (advertising mode) is changed from ON to OFF!
Three: Then remotely shut down, boot, press the home page, the original hidden input interface menu function appears! Select the TV item, enter the AV interface, and click the 0K button. After connecting the signal line, the TV finally appeared!
If you still can't read it, just browse the operation diagram and believe that you have learned it.
