SAMSUNG Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SAMSUNG | SYNCMASTER 3NE | Horizontal without adjustment and with a very large size. | After checking the horizontal size adjustment potentiometer and the adjacent circuit (q407, q406) I found the diode d406 uf5404 leaking. After replacement, the monitor returned to horizontal adjustment | ||
| SAMSUNG | CQA-4147 | It came cocked with a jumper on the zener d100, what for? power supply at maximum (155v) and high voltage with only 40v instead of 90v at the corresponding tp. | Replacement of ic 402 (hv2 hybrid) | ||
| SAMSUNG | SYBCMASTER 3NE | Horizontal position too wide, making it impossible to adjust using the button. | Check q406 and d407. | ||
| SAMSUNG | Monitors of any brand that have low brightness and use Samsung tubes (blue label). | If the filament tension is ok and g1 and g2 are also ok, it is almost certain that the tube is defective! | |||
| SAMSUNG | SYNCMASTER3 | Excess width | Q406=mje806 | ||
| SAMSUNG | SYNCMASTER 3 OU 3NE | Doesn't start | R613 r614, c621. Note: there is no point in measuring the c621, you have to change it | ||
| SAMSUNG | SYNCMASTER 3 NE | The monitor magnetizes normally but nothing appears. | I checked the d505 diode and realized that it was completely shorted. I replaced it with the traditional 1n4148 and it worked perfectly! It was what I had on hand at the moment. | ||
| SAMSUNG | SYNCMASTER 3NE -CQB4147 | Normal controls, but the width is smaller than normal | Replacing capacitor c422, or other capacitors associated with the collector of the horizontal output transistor | ||
| SAMSUNG | SYNCMASTER 3NE -CVM4967P | Power supply does not start, or works after several attempts. | Replace c621, c619 | ||
| SAMSUNG | 753V | Insufficient width | Q419 | ||
| MONITOR SAMSUNG | 551V -PN15VS | Retrace line and dot in the center of the screen when turning off | C101 (102k/500v) na placa do trc. | ||
| SAMSUNG | CN3383 | TV doesn't turn on and the LED is off. the +b of 130, 15 and 5vdc ok. It doesn't activate the stand-by and it doesn't have the 9v that powers the computer. defect | The bad crystal. | ||
| SAMSUNG | CB5035Z | Stuck in osd mode, no functions | Change the eprom, check that the earthing of the green cable running from tuner is ok | ||
| SAMSUNG | CB5020 P58SC | Tuning not stopping | Replace r116 120kΩ this was open circuit | ||
| SAMSUNG | CX5012 | Volume low, even at maximum setting | Replaced ic601 tc4066bp close to if can | ||
| SAMSUNG | CS3339Z | No picture no sound | Faulty ic tda6107q on crt board | ||
| SAMSUNG | CW28C33N | Dead. in safety mode | Looks like l.o.p.t but was traced to small decoupling cap on 200v line on tube base, dead short | ||
| SAMSUNG | CK-5320ZR SCT11D | Field collapse | Check r410 1Ω in feed to d403 for o/c | ||
| SAMSUNG | CB7230WT | Vertical output problems, vertical output ic fails repeatedly ! | Fit a new ic, clean old heatsink compound, add fresh compound thinly on the surface. now disregard all the other modifications previously suggested and add a large heat sink on the existing heatsink screw another one on top | ||
| SAMSUNG | TXG2547 K51A | No power, voltage not changing on pin 18 ic901 szm-368et2 | Check dz906 short, key-in 1 pin 9 of ic901 |
