Semp Repair Guide: Common Issues and Fixes
Brand | Model | Fault | Detailed Problem | Solution | By |
---|---|---|---|---|---|
SEMP | LC4245F | 5v weak, pulsing. | Clamper circuit | Rb905 cb903 | Davi.sls |
SEMP TOSHIBA | LC3246(B)WDA | TV does not tune channels or has difficulty tuning air channels | Ceramic smd capacitors c114,c116 next to ci n100 | Eletrônica JM/Júlio | |
SEMP TCL | 32S6500S RT41PB-AG | TV with sound without image | Burned out led (1 led) | Replace of the complete, new bar kit and chain reduction. I replaced the two power supply resistors with just one whose value was 0.144ma. | Cesar762 |
SEMP | 2134 SK11 | Turns on normally when increasing the screen, a horizontal line appears on the screen and keeps restarting. | R333 eo c636 | Replace the 220 man r333 and the 1000μF16v c636 tv working perfectly! | Sinailson |
SEMP | 1453 O. AV U19 | After a while the image starts to shake and closes the vertical | R336. 180r | Just replace and run for the hug, I'm grateful for the help I've already had | Rogério TV |
SEMP TOSHIBA | 48L2400 | Inoperative without standby | Nb905 | Replace the ci nb905 fsl206mr and just run for the hug. | Sinailson |
SEMP TOSHIBA | DL4061 A | TV turns on normally and then doesn't turn off or keeps turning on and off without stopping. | U100, q121 e q122 | Replace or solve | Alessandro Barcelos |
SEMP | LE3264 (B) W | TV sometimes turns on sometimes it just keeps flashing red led | Cold welding at the power supply | Resolder | Dinho |
SEMP TCL | 43S615 | The TV turns on, the backlight turns on, the screen stays dark blue but no image appears. | Check if the 12v voltage on the ads501 smd diode is below 12v | Auterated 1m2Ω smd ar523 resistor. May God bless you all! | Eletrônica JM/Júlio |
SEMP | DL3244(A)W | Turns off instantly out of nowsound after some time, first it takes a long time, then it turns off more frequently, faster. After presenting a plop/noise in the sound | As I changed the c.i fr9889 that regulates the "core" power supply (1.2 volts) for the processor, I forgot to get the position of the component | Fr9889 next to the processor heatsink. This regulator supplies 1.25 volts and was supplying 1.34v, which caused the TV to turn off. After changing it, it got 1.27v and was perfect. | MIGUELTV |
SEMP | 48L2400 | Any problem with little or no back light | R765 = 100k | R765 = 100k | |
SEMP | 1452 | I'm sound | I changed all the electrolytic capacitors, they were all good, it only resolved after I removed the q611 | Remover q611 | |
SEMP | TV2134(C)SL | Character and image duplicating noise in serrated deflection coil | Just place the tip of the screwdriver that has a magnet on top of the L 302 coil and you will see the change | Take a dvd lens magnet and stick it on top of the reel, which solves the problem from the factory it comes with this magnet but over time it falls off | RONY ITAPORANGA PB |
SEMP | 32S5300 | LEDs turning on with weak intensity, with a burnt out LED symptom, voltage at the LED power supply output (connector) at 45v, must be at 65v | Dr01 diode shorted | Dr01 diode replacement | Claudio Jorge Eckert Junior |
SEMP TOSHIBA | LC4246FDA | Doesn't start. power supply with integrated inverter does not arm secondary. | Rw910 de 100k/2w aberto | Replacing the resistor and general preventative resoldering of the power supply. | CARDOSO |
SEMP | LC4055(B) | Turns on the image for 1 second and turns off the image, the rest continues to work | After checking the pfc voltages ok, +b 24v ok and inerter on ok and brightness control everything ok but the inverter circuit continued to trip 1 to 2 seconds after switching on | After removing the inverter PCI, we tested the leakage to the housing on the lamp terminals, the same ones that fit the inverter PCI, then we scraped them all and reassembled them later, tsound is a video of the repair summarized on the channel directly on the defect, link: https://youtu. be/i7fax9gid_g | YouTube Direto no defeito |
SEMP TOSHIBA | DL4077I | It doesn't turn on, it just keeps the green LED flashing | Cold solder on logic board | Resolder the entire board underneath | Deo Eletrônica (81)98904-0186 |
SEMP | TV 1451NAV U18 | Noise in the throat when turning on with the panel reducing and turning off sometimes it turns on after a few attempts | I replaced q865 smd photo coupled and c865 10nf | Replace of other components | Rogério TV |
SEMP TOSHIBA | DL4844(A)F - | League. STBY LED lights up, does not accept C.R. commands. and keyboard. | N806 shorted and n804 altered, en pin less than 2.4v, normal 3.1v or more, depends on the circuit. | The components n806 and n804 were replaced. | Cesar762 |
