| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SAMSUNG | 29K40MQ | Frizzy image, horizontal frequency | Low or zero 4n7/400v polyesterc 404 capacitor | Capacitor replaced | Carlos Roberto da Silva |
| SAMSUNG | SINCMASTER | Delicate in white image | Xray protection acting | R507 replace from 10k to 4.7k | JURANDIR |
| SAMSUNG | CL21N11MQ | LED flashes, does not start. | Verificar c108 ->1000mf/10v | Farias | |
| SAMSUNG | CX3312Z | This TV had a trapezoidal image, with a reduced frame, narrower at the top, with 4 vertical folds at the top of the image. | Horizontal deflector coil with corrosion/verdigris. | Valecovo | |
| SAMSUNG | CL21M21MQ K16A | 125v power supply changed to 150v | Resistor r831 123k alterada | Scorpion | |
| SAMSUNG- MONITOR | SYNCMASTER 793DF / 793V / 591V -CHASSIS LE 17*/ LE 15* N 15V* LE 17*/ LE 15* | Reduced vertical | Procedures: close a short between collector and emitter in q 414-> image opened? no -> check/replace c 405 and c 406 circuit correction s, eeprom and dy; yes->in the user menu, act on the width of the monitor, with a multi-test check on the base of q 414 if the voltage changes between 2.09v ~ 1.63v; acted? yes-> check/replace r 419 q 411, q 412 and q 413; no->check/replace r 23, ic 201 (micom),width circuit, ew mode_size and size_adjust. | ||
| SAMSUNG - MONITOR | LCD - CHASSIS : HA 15*, MH15* GS15M*, MJ 15*, MH17* | The monitor loses the video signal intermittently, but when the “power” button is pressed, the monitor starts working again. | Some monitors present this symptom due to a defect in the H385 voltage regulator IC batch | Monitors that have a regulator IC with this specification: h36* or h38* and have an intermittent “no video” defect must replace the IC with another according to the specification: g960t45r; 1203-002853, position of the regulator IC on the chassis according to its version: ha15a/b-> ic 601; mh15a/j/n->ic 103; mh17a/j/n-> ic 103; mh17f->ic 300;mj15a/b/c->ic 602 gs15m->ic 602. | |
| SAMSUNG - MONITOR | SYNC MASTER 793 DFX /LE17K*; | White balance image flicker; -raster. | Procedure: 1st) test the device to check the symptom. 2nd) if the device presents one of the symptoms mentioned, open the device and clean the pins of the CN101 connector on the monitor's video card. cleaning the pins must be done with a contact cleaner (for example: wd, contact matic. ) 3rd) close and test the device again: - if the symptom has disappeared, record this defect in the service orders with code c99 ( other mechanical adjustments) and not with code b01 (welding). - if the symptom has not disappeared, check the other electronic components. | Note: also applies to sync master 753v / an17v* chassis models; sync master 753s / an17l* ; sync master 591v / le15*. | |
| SAMSUNG - MONITOR | SYNCMASTER 793DF / 793V / 591V -CHASSIS LE 17*/ LE 15* N 15V* | Does not turn on (LED flashing) | Interrupt the horizontal deflection in the circuit by lifting the coil terminal l 501 if the power supply is oscillating between 54 ~58v problem in the horizontal deflection circuit. check: c 502, q 590, q 490, d 406, ic 401, t 501 and peripheral components the horizontal line and high voltage control. | ||
