จอคอมประกอบไปด้วย Power Supply + ชุดขับหลอด LED + Tcon Board + หน่วยประมวลผล ครับ เวลาซ่อมต้องลำดับอาการเสีย เหมือนกับที่ผมพยายามนำเสนอวิธีการครับ ส่วนตัวเสียนั้น มันมีมากมายหลายเหตุการณ์ครับ ก็จะพยายามทำลงไว้ให้เรื่อย ๆ ครับ ล่าสุดใน Live สด ก็พาไล่วงจร Boost ไฟเลี้ยงหลอดภาพอยู่ครับ ต้องรับชมหลาย ๆ ส่วนประกอบกันครับ (อย่าลืมกดแจ้งเตือน)
