SEMP Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SEMP | TV1454 | Does not turn on, just stand-by | Eprom | ||
| SEMP | 2934 SK91 | TV with an all-green image | Please 503 | Remove the Q503 transistor from the RGB board and the image will be normal. | Sinailson furtado |
| SEMP TOSHIBA | DL3944 | Istandby changes to green but does not turn on low 12 power supply inverter circuit | An analysis of the defect was carried out and we found a voltage of 12 volts in standby 7.5 volts | Transistor vw953 open open resolved the issue | ELETRONICA SALES. NATAL RN |
| SEMP TOSHIBA | LE2445[A] | Turns on then turns off to stand-by as soon as you apply the hdmi cable with signal | After checking the processor for heating, I reballed it and cleaned it with alcohol. | Note: HDMI didn't work but the AV was fine!! | Medeiros Eletrônica/Barbacena MG |
| SEMP TOSHIBA | 40L1500 | LED off or on and off | Regulator v809 z, zv | Next to the two resistors in the middle of the board | Adrian Chapadão do Céu Goiás |
| SEMP | TV2134(C)SL SK11/SK91 | Standby LED accesses but does not accept commands (does not turn on) | Zd202 zener diode on the sda line of the leaky memory. | VALDEMAR ELIAS | |
| SEMP TCL | L40D2900F | It has sound and no image! | Burning LED bus. solution: reduce the voltage that was 85v on the LEDs by removing the two resistors (0r) next to the LED bus connector, the voltage dropped to 73v. replace the LED bus with a new one. | evandoviana | |
| SEMP | DL3960AF | TV with red LED and flashing 3.3 volts varying | Replace ic u201 e d203 | REGINALDO JOSE DE LIMA | |
| SEMP | LE1474 A W | Does not come out of standby. | Change eprom memory. | ||
| SEMP | LC4246FDA | No audio | Remove smd transistor v204 has the letter b right next to it | 3R | |
| SEMP TOSHIBA | TV2157 | No sound, both on the av and on the channel | D412 zener 10v shorted or fga | To replace | Velk |
| SEMP TOSHIBA | LE3256AW | Inoperative, stand by LED does not turn green, tsound is no sound or image | Replaced flash memory | SEMP TOSHIBA | |
| SEMP TOSHIBA | LC4242WDA | Doesn't start | Defect in the power supply measure all voltages 0v porcelain resistor 1.8r 5w near the relay open, so this resistor opened it fuse + resistor I replaced it with another one resolved the voltages appeared | TV everything ok resolved | Andre |
| SEMP TOSHIBA | LC4242WDA | Doesn't start | Defect in the power supply measure all voltages 0v porcelain resistor 1.8r 5w near the relay open, so this resistor opened it fuse + resistor I replaced it with another one resolved the voltages appeared | TV everything ok resolved | Andre |
| SEMP TOSHIBA | LC4242WDA | Does not tune digital channels | Varicap in short 5bf6009 and ec40 1000uf 10v tufted, so I can't buy varicap doesn't sell, I decided to change the ts3b ver:1.2 board | Defect resolved digital channels everything works | Andre |
| SEMP TOSHIBA | 32AL800 | Does not turn on, green LED is on | Without the 12v voltage generated by the u100 | Replace ci mp1593dn in position u100 | Lucas |
| SEMP | DL4061 | Burnt out LEDs reduce LED voltage | Remove r13 and replace r 12, put 10k | juci | |
| SEMP | TV2084FAVU | No audio | Saida ci replace tda2611a | reginaldo moronte,eletronica junior caldas novas | |
| SEMP | LC4246FDA | Turn on lamps and then turn them off | Activating timer protection | Put a resistor on pin 11 of CID n701 (oz9976) to ground | FABIO DULLIUS |
| SEMP | 2090(I) U14 | Vertical completely closed | The 5v line was low | Replaced resistor r885. just replace it and solve it | JS Eletronica (Nilsinho Rodrigues) |
