Check input signal format.

Is it supported?

Y

Check AC cable for damage

For damage or open conductor

Y

Check JK3800

Can you see the normal waveform?

Y

Check the input of MTK(IC105).

Measure waveform at C345, C346, C319, C320 because it’s more easy to check.

Can you see the normal waveform?

Y

This board has big problem because Main chip (MTK) have some troubles.

After checking thoroughly all path once again, You should decide to replace MTK or not.

Replace JK3800
