TROUBLESHOOTING
Check TU401 Pin15(Video output),
Pin16(Sound output)
Can you see the normal signal?
Check the output of TR(Q503).
Can you see the normal waveform?
Check the output of Main IC(IC100).
Especially you should check
The H,V sync and clock.
Can you see the normal waveform?
YES
YES
NO
Could you measure voltage of TU800 & IIC
lines?
Are they all normal?
YES
NO
You should check power line
& IIC lines.
YES
You should replace TUNER.
NO
You should decide to replace TR(Q503) or not.
NO
After checking the Power of Main IC(IC100) you
should decide to replace Main IC or not.
This board has big problem because Main
IC(IC100) have some troubles.
After checking thoroughly all path once again,
You should decide to replace Main Board or not.
