And similar to the video on ILA8362A.
Another reason for the lack of serviceable Vertical video processor and
personnel mikruhoy:
31 In the absence of voltage, which is to configure the tuner. This voltage is
applied to stabilize the circuit size screen (43 foot ILA8362) through resistor
100k.

There was no food. Replacement:
VT800 - STR4NK60Z, R811 - 4.7 - 7W, R812 - 100 - SMD, DA800 - UC3842.
The reason for failure is unknown, but in this model, there was no capacitor
