If there is no sound or picture, first check if the voltage pressure of J7 Pin2 is high (more than 3V). If it is, then check if there is voltage pressure in the pad of the L806 (12V) and L807 (5V). If these checks do not resolve the issue, you may need to change the U7 or Q810 components.

If you are experiencing issues with the color display on certain channels, showing only black and white, you should first change the channel to the right sound system (PAL-M/N NTSC-M) and check the picture and sound system of this channel. If the problem persists, you may need to update the software and reboot the device, or consider changing the mainboard.
