Philips FTV SDI Schematic

Repair Scenario FTV with SDI PDP

First check complete set

Fault Symptom?

No

Repair Philips application

Scavio = FM242

SSB EMG = FTP1.1 (with LVDS tool??)

Power Supply

is working ?

Check if LVDS from SCAVIO

or SSB board is OK

Use LVDS Tool when possible

Output of SSB / SCAVIO

is OK?

SDI repair Scenario

Fault finding; Display fault

No
