  1. DIAGRAM BLOK OLEH : OFANI DARIYAN XI EB 30

  2. VIDEO BOARD • Video Input = Blok iniberfungsimenerima input (masukan) berupasinyal data dari CPU • Video Pre-Amp = Di dalamblokiniterdapatsebuah IC yang berfungsimengubah data menjadisinyal VIDEO dansinyalsinkronisasi V (vertikal) dan H (horizontal). Padacontohtersebut type IC 101=KB 2551 • Video Output = Terdirirangkaian IC 102, berfungsimenguatkansinyal video dari Video Pre-Amp yaitusinyal R (Merah), G (Hijau), dan B (Biru)

  3. MAIN BOARD • Brightness Control Ialah Pengatur Kecerahan Gambar. * Dilakukan dengan mengatur tegangan awal/tegangan mula-mula (Teg. DC) katoda CRT. • Contrast Control Ialah Pengatur Ketajaman Gambar. (dalam hal perbandingan hitam/putih) * Dilakukan dengan mengatur LEVEL.

  4. MCU (IC 201) Berfungsi menghasilkan sinyal-sinyal sinkronisasi (Horizontal+Vertikal) dari sinyal DATA Input. • Horizontal / Vertikal Processor Berfungsi memisahkan sinyal-sinyal sinkronisasi, sehingga dihasilkan sinyal sinkronisasi Vertikal, dalam hal ini dilakukan oleh IC 401.
