Semp Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SEMP | TV2134 SL SL | LED turns on and off and capacitor is charged, +b with 170v | Photo coupler | Adrian Chapadão do Céu | |
| SEMP TOSHIBA | 2934(B)SL SK-9 | The power supply would trigger but then cut off and make a noise in the oscillator, heating up the r632 | The defect was the d3006 short and the vertical output | MESSIAS ARAUJO | |
| SEMP TOSHIBA | 2134 | Non-vertical cold welding | Solve | Rafael | |
| SEMP TOSHIBA | 32 | Defective LEDs | Change LED bar | Works with any LG 42 TV LED | Fernando |
| SEMP STI | 32L2400 | Burning leds | When checking the LEDs you notice excessive heating | R764 and r765 connected to the base of the v761 limit the current to the LEDs, I added a 5r6 resistor and they no longer burned | Mário Martins |
| SEMP | U16 U16 | Power supply with all voltages turned off | C861 ceramic | Replace the same | SEVERINO ALVES |
| SEMP | TV2134(C) SK-11 | I'm sound | C636 1000uf 16v | The replace of the same | wemersonwcp |
| STI SEMP TOSHIBA | LE4050(A)FDA | Doesn't start | 5v power supply doesn't work | Changing the three photocouplers | sergio |
| SEMP | 2134 SK91 | Image with black triangles in the two corners under the screen and the keys don't work | Corrupted eeprom memory | Replace memory 24c08wp | Fofao |
| SEMP | 2982 LEM9 | It wouldn't turn on, the LED would light up and go off, it wasn't c819, it was r884, change without media | Replace r884 | Replace r884 | Eletrônica Alves |
| SEMP TOSHIBA | TV2998EMS | When it turns on tsound is no sound | Electrolytic capacitor c449 x 1000uf near the flyback with little capacitance creates a ripple on the 12v line | I replaced the capacitor and it was resolved!! | GEMASI |
| SEMP | 2134 SKY | The TV had a light streak in the center of the screen horizontally, typical of a damaged vertical. So many attempts to fix it but nothing resolved. | That's when replacing diode 306 close to d305 (close to the flyback) solved the problem. This diode was good, but it didn't work. With the replace everything was ok. | Marcos Antonio Lizzi-Microlizzi-Confresa-MT | |
| SEMP | 2134(C) SL SK11 | With red image | 2k2 resistor on tube plate, measuring good but defective | Replace the 2k2 r520 on the kinescope board | CST eletrônica Serrota Senador Sá Ce |
| SEMP | 2934 SK91 | Squeaking sound like I was out of sitonina | R104, r105 | Replace only costs 100r | <small>This email address is being protected from spambots. You need JavaScript enabled to view it.</small> |
| SEMP TOSHIBA | 2134 (B) SL SK11 | When turning on the power key, the LED flashes and goes off by hitting the relay, and with a high power supply with + 163 volts | I did some research in the power supply control circuit and found an open 2k2 resistor 604. | I replaced the voltages and it normalized and the TV looked great. | Leonardo |
| SEMP TOSHIBA | TV2959 FS6 | Turns on and off with the standby LED off | D440 shorted | Replace | juci |
| SEMP | TV2134SL | TV has white stripes and a black stripe from the middle down when turned on, then returns to normal | Capacitors c318 and c319 | Just replace them | jose isael |
| SEMP | TV SEMP MAXCOLOR FS TUNING | Blowing fuse [802] | Defective flyback, the lamp in series kept pulsing, it means connecting it to the mains and blowing the fuse. | Replace flyback . | kandeia |
| SEMP | LC4246FDA | TV doesn't turn on, just green LED flashes quickly, 12 volts fluctuate | Replace the qo465r chip and the smd transistor nw 901 obs the tr I got from another pc | May the Lord bless you | Irmao |
| SEMP TOSHIBA | LC4242WDA | Does not turn on, relay continually arming and disarming. | Standby power supply with 0v at the output due to the VCC output of the ci q840 with 0v. | Component replacement: c843 (22m50v), d846 (zenner), f840 (800ma) and q840 (a6169) | Ralyson |
