Viewsonic va2226w 114/7/2024 ![]() No horizontal, single white line up centre of screenĬheck fuse link J114 which feeds 220v to collector of Q881 Silicon Graphics Monitor Model: 340C (Panasonic PanaSync P70) Reduced width with failure to store settingsĭry joints on the display mode relay RL501 I found C102, C109, C112 and C101 on sub board o/c plus C19, C8 and C9 on main pcb also o/c, all 105deg caps. Remove power supply (very easy on this monitor). Monitor dead, green led comes on then fades out, EHT sometimes starts up I checked many parts in the Video driver area and found all was ok but IC MM1207 was found to have failed I found following parts had failed: Q425, C4924 and R497 (10ohm, 1w), the horizontal output transistor was also short circuit, replaced with type BU2527ĭell Monitor Model: D-1728D-LS (FCC ID A3LCMG737) Kds Monitor Model: VS21E (Evoked 2100K Chassis) Vertical problem, small picture, cannot adjust, sometimes rollingĬhecked vertical section and found resistor R527 (10ohms) located near ICU501 had gone high resistance, replacing resistor cleared the fault Likom Monitor Model: L503RDN (13MLB0004424 Chassis) ![]() Replaced IC802 and unit then powered up ok Infinity Monitor Model: 14ED (W745114477 Chassis)Ĭhecked and tested power supply section, all resistors and filter capacitor checked ok.
