Semp Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SEMP | 2090 | Low supply +b around 75v, all the components that cause this defect were analyzed and they were all good... | Q432, smd transistor in the center of the board. | Do not replace, take off the board. (tec, edfersom varjota-ce) | Edfesom |
| SEMP | 2982 | After changing capacitors c637 and c636, which were open, the sound returned, however, it was intermittent. | Q630 even though it amplifies normally, it must be replaced, I discovered this after wasting an entire day changing parts. | Replace the q630 | Edfersom |
| SEMP | 2134 CSL | Turn on and off | Diode d305 in the -16v supply from the vertical. normal average time, no time. | Swap d305 (fr104) | MARCONES DE ARARIPINA-PE |
| SEMP | 2134 CSL | Constantly turns on and off. | -16v diode of vertical d305 modified. | Replace d305 | MARCONES DE ARARIPINA-PE |
| SEMP | TV2134 C SL SK11 | Sem as no rf no of normal | Defect is the r 805 of 33k next to q 801 | Jr eletrônica | |
| SEMP | LE4057L | TV takes a while to turn on, and when it turns on tsound is no image, just backlith | Altered capacitors | Replace capacitors c833, c813, c841, c856, c837, c803. all 220x16. solves many problems | Abel Fabricio |
| SEMP | LE4057L | TV takes a while to turn on, and when it turns on tsound is no image, just backlith | Altered capacitors | Replace capacitors c833, c813, c841, c856, c837, c803. all 220x16. solves many problems | Abel Fabricio |
| SEMP | 32L2800 | Damaged LEDs | Altered diet | Leave only the 370k resistor and capacitor on pin 6 of the stage oscillator IC. | Multimarcas/Acarí |
| SEMP | 1454 U19 | The image showed blue stripes in constant movement, along with deformation of the horizontal and vertical plot. | Q906, smd transistor located on the rgb board. | Remove the transistor. (tec. edfersom varjota-ce) | Edfersom |
| SEMP | TV2134 SK11 | When turning on the TV, the stand by LED did not light up normally, the oscillator does not arm, the relay only hits once | Defective c621 capacitor | You can replace without measuring | Max Coelho |
| SEMP TOSHIBA | 32L2300 | USB overload message, and it does not accept any commands! | Remove the coil that powers the IC160 responsible for the USB port! | Rodrigo cofferi | |
| SEMP | LC4247F | No image only audio | C 912 with leakage 12v vlcd or tcon power supply | Replace without testing! share because time is $$ good luck!! | Jhone eletronica |
| SEMP TOSHIBA | U14 U14 | Takes time to turn on and light filament | C 419 47x50 proximo saida horizontal | AGILDO ANDRADE | |
| SEMP | DL4844 | Turns on, appears immediately, disappears image and is stuck on the green LED, does not respond to any command. | I measured the LED bars and they were altered, I replaced them and the problem persisted. | If changing the bars does not solve the problem, check all the 1r0 resistors in the driver region, in my case tsound was 1 open, this caused protection even though the bars are new, if tsound are none open and the bars are guaranteed to work, replace the driver which solves the problem. . | Kelvin |
| SEMP TOSHIBA | DL3975I | TV just keeps blinking green LED | 12v power supply pulsing | Replace the dp9 ba158 diode. Tsound's no point in testing, I put an sk4f1/10 in and it worked fine. | Alexandre Oliveira |
| SEMP TOSHIBA | DL4077I | TV just keeps blinking green LED | 12v power supply pulsing | Replace the dp9 ba158 diode. Tsound's no point in testing, I put an sk4f1/10 in and it worked fine. | Alexandre Oliveira |
| SEMP | TV1490 U14 | Alloy with reduced frame and low secondary power supply 75v | After checking almost everything I decided to change the xa01 8.000/16 crystal and to my surprise it did the trick. | After changing the TV ok. | George Pontes |
| SEMP | TV1490 U14 | Alloy with reduced frame and low secondary power supply 75v | Capacitor c864 de100uf 50v, with low capacitance. | After changing the TV ok. | George Pontes |
| SEMP TOSHIBA | 14415N U18 | Blinking led | C865 10 n shorted | Changing is running to dim dim | Francisco de Jesus Conceição l |
| SEMP | 1022 | Doesn't start | Replace mosfer bu808df | Replace component and run for hug | R&w cell Rodrigo klein |
