Semp Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SEMP TOSHIBA | LC3255(A)WDA | It doesn't work, nor does standby light up. only the VD503 LED (red) on the main board lights up. | L803 open and c812 or 814 (smd 10ufx16v) shorted. | Replace capacitor with another equal one. replace l803 with another equal one or place a 0Ω resistor. | EvandoViana |
| SEMP | TV2922JFS LEM10 | I'm sound | Replace diodo zener d421 5,1v | DJ PITUKA | |
| SEMP ULTRA SLIM | 2134 SK 11 | Reduced screen on the side capacitor and diodes replaced and defect continues | After changing capacitor 4.7uf 250v | savio | |
| SEMP | TV2922JFS | Does not turn on, 45v power supply | Replace diodo zener d863 ,5v6 | DJ PITUKA | |
| SEMP TOSHIBA STI | DL3954 | Disappear image after a few minutes. without image, with sound and backlight. | Defect in the display's tcom, specifically in the c.i cm501, after a while of use it cuts the voltage lx2 on pins 13-14. | Replace o c.i cm501. | Darci Denzer |
| SEMP | 2134 | Completely inoperative, when plugged in it only charged the primary capacitor. | C608 10nf ceramic capacitor | Replace without testing | EDFERSOM |
| SEMP | DL4045 | The TV turns on, the image appears 1 minute later, it turns off | Defective ci smd n805 | Flavio Aragão | |
| SEMP | TV2134(C)SL SK!! | Tv sem as no rf e no av | Q402 (1815) responsible for mute. | Just remove the transistor and run for the hug. | David jr. |
| SEMP TOSHIBA | DL3975 (A) | Turning off after 15 minutes | Replace u9 al1117-3,3v cp10 100mf 16v | Replace without measuring run hug | Luiz Macário |
| SEMP | 2122 U19 | Black screen with features no sound no drizzle | 9 turns left of the sinoscope pin replace q405 for the same just take the coin and run for the hug electronic equipment fl | Lucas | |
| SEMP | LEM9/FS7 | When plugged in, it simply turned on the stand-by and went out quickly, leaving the power supply capacitor charged. | The 220k r851 of the +b feedback line open. | Replace the component and move on to the next one (edfesom) | EDFESOM |
| SEMP TOSHIBA | LC3241W | Doesn't start. | Internally damaged relay and exhausted electrolytic capacitors | Replace the relay (12v x 250v) and the blue electrolytic capacitors (22μF x 35v and 50v) | Darci Denzer |
| SEMP | 2134 SK11 | When turned on, the LED flashes and the relay hits quickly, and turns off charging the power supply capacitor | Open 220k r633 | Replace the component. (edfersom) | Edfersom |
| SEMP | LC4245W | TV turns on but back light comes on and goes off immediately, giving just a blink | Lack of 12v on the main board, fuse f801 open due to the ceramic c154 in a short circuit. to varicap. | Alberi F S | |
| SEMP | LC4245W | Only turns on the backlight, without image. | Found broken fuse on main board position f801 is a blue fuse. We found a shorted capacitor on the t-con board that was causing the defect, just remove it and change the fuse. | EC | |
| SEMP | LC4245W | Defect missing characters or colored characters in the menu, volume or TV information. | Defect in memory n302, it looks like nand memory, it has 66 pins. He is the one who provides character information for the TV. Just change, I didn't find his data for sale so I could re-record it. Remembering that it will not solve black screen defects, the memory for black screen defects is n304. | EC | |
| SEMP | LC4245W | Audio noise, normal image | Defect in d601 (main board), the diode was open. To facilitate its position, it is slightly below the sound output, close to 2 connectors. | EC | |
| SEMP | LC4245W | No audio, normal image | Defect in the n801 (main board) that generates 5v, the 5v was low and did not generate audio. | EC | |
| SEMP | LC3246WDA KK | TV does not go to standby green LED on | Cause of the defect lack of 5v in the 1.5v voltage regulator IC.. | Make a jump from l801 to l807. Thanks to my colleague Diego Lima for the tip posted. | TV CENTER GUAIBA |
| SEMP TOSHIBA | DL4053 (A)W | Does not turn on, nor does the stand by LED | Measure n805 middle pin with the negative housing, if it is shorted it was already a processor. If it's not shorted, tsound's a solution! | Replace nw910 and nw955 both are shorted primary and secondary power supply sector. I hope I helped!! | Maike Sorriso-MT |
