Dear dc_rock,
These the most common failures for this TV Model VS-5043- VZ3:
1. Check base bias Voltage of Q217, for 0 VDC (BIASED OFF) if .7 VDC (BIASED ON) check C268 (22 UFD 50 V) off C OF Q215 V-Protector on the SIGNAL PCB.
2. Vertical Beam Blanking Active, check PIN 4 of IC401 for 3 VDC. If missing check IC202 (5V REG) PART # 266P932010, on The SIGNAL PCB.
3. Check Pin 6 of IC200 for 9 VDC if low or missing check IC203 Part#
270P210010 on the SIGNAL PCB.
Thanks for using FIXYA, big IRISH.
