Checking device. [U2000 : ADV7850]
Checking the reset waveform. (VIDEO DECODER)
Check item(25). Checking the reset waveform :
Check the waveform.
Is the TP waveform of the TP near the VIDEO DECODER (U2000)
correct (like the one shown in the diagram) when the power is
turned on?

U2000
RESET
Check the reset circuit between
CPU [U6201] and VIDEO DECODER
[U2000].

DECODER [U2000] is faulty.
Replace with a new device.
Recheck from check item (25).
If it does not work, replace the
PCB.
NO
