EN 12 L03.1U AA5.
• Set turns on, but without picture and sound. The screen
shows snow, but OSD and other menus are okay. Blinking
LED procedure indicates error 11, so problem is expected
in the tuner (pos. 1000). Check presence of supply
voltages. As “Vlotaux+5V” at pin 5 and 7 are okay,
“VT_supply” at pin 9 is missing. Conclusion: resistors 3449
& 3450 are defective.
