Hi. I have a very strange problem with my dm800 , i enter in my dm without anyproblem , i surf trough the menu and switch channels without any kind of problem but when i put on any channel i get audio , i see that is decoding the channel but no image ( i tried with DVI-HDMI and with scart ) but nothing. Funny is if i enter in the web interface i get the image with vlc Anybody can help with a solution? Thanks
Just as the picture shows about the u20 center pin, check the connection from the U20 center pin to the resistors, and check the resistors etc. So also check the voltages to/from it etc. In any case, when there is a issue in that sector then it gives a same problem as you describes. An other picture which shows the same about the u20, and more is this.
hi , i checked this mainboard with another tuner and i confirm the same issue , tuner ok and maybe how you said here its something faulty on the mainboard , i will try to solve the problem when i have a bit of time. thanks
