    This is all I found on Mits site. Don't think this pertains to your problem because you have the three r-b-g horizontal lines, right? Still think it's a vertical deflection problem (IC or Cap). Search the Mitsubishi Technical Database Model Number: VS-683R Symptom: NO PIX, SOUND OK Cause #1 1. CHECK FOR 1200V AT DG CONNECTOR (PCB MAIN) OR AT SF CONNECTOR (GREEN CRT PCB).IF MISSING CHECK C546 AND D515 FOR SHORTS, R569 FOR OPEN. LOCATED ON PCB MAIN OFF PIN 1 OF FBT. C546 - #189P072020 (.1UF 1600V) R569 - #109P052010 (FUSIBLE 100 OHM 1/4 WATT) D515 - #264P146010 (RC-2) 2. IF CRT FILAMENTS ARE NOT LIT CHECK FOR OPEN FILAMENT SERIES RESISTOR R545 (2.7OHM 2W) ON PCB MAIN. 3. CHECK FOR 5V AT IC711 PIN 3. IF MISSING, REPLACE IC713. LOCATED ON PCB-MAIN. (272P16201)
