SEMP Repair Guide: Common Issues and Fixes
Brand | Model | Fault | Detailed Problem | Solution | By |
---|---|---|---|---|---|
SEMP | TV2091KAV U15 | It only turns on when it wants, and when it turns on, if the control turns it off, the LED starts pulsing, after a few seconds the LED turns back to normal and it turns on. | Replace d830 1n4148 | dj pituka | |
SEMP | TV2091KAV U15 | LED flashing directly and the power supply is 130v, if you remove the q432 the TV turns on with the normal 113v power supply but without video, the characters do not appear | Replace micronas q501 8843cpng4v47 | dj pituka | |
SEMP | 1488 U14 | Turns on with a dark screen, if you enlarge the screen, only a frame appears in the middle of the screen | R873, with SMD cold soldering at the power supply. | Solve r873 | MARCONES DE ARARIPINA-PE |
SEMP | TV2934BSL SK91 | Burning horizontal transistor, heats up until it burns | Change coil l301 next to the flyback. | dj pituka | |
SEMP | TV-2177 | Vertical sidebar with stripes | Exhausted 330uf/16v c449 capacitor. next two vertical. | After changing the TV ok. | George Pontes |
SEMP | TV2934BSL | Channel does not enter rf, all voltages present in the varicap | Change 10k r106 next to the varicap | dj pituka | |
SEMP | TV2982 | LED lights up but doesn't turn on, unstable power supply | R878 39k changed | HAHNRAHN | |
SEMP TOSHIBA | TV2959JFS LEM10 | Turns on and off, then the LED goes out | Open 220k resistor r851 | Replace the same | Ofina dos eletrônicos |
SEMP | TV1452 | Completely stopped, no standby | Photo coupler | Replaced and solved the problem | Eletrônica Renascer |
SEMP | 1454 (P)SL | TV turns on with a rainbow-colored screen without the characters | Ci do vertical. n401. (utc78040) faulty swap | Put a ci (stv9302b) it's great | Andre mamilha |
SEMP TOSHIBA | 40L2400 | Without any sign of life | No 1.15v voltage on the l801 coil even with pin 7 of the n801 with 4v. | Replace n801 and the TV works again. | Andre crisópolis |
SEMP | TV1454(P)SL U19 | TV won't turn on when LED flashing comes on | Change resistor 235 33k changed killing 5 volts from pin 8 of the fais everything | Enoque Dantas | |
SEMP TCL | 49K1US | Blue fabric | But now when it turns on it gets a blue screen it stuck on a blue screen | Juliana teles nogueira | |
SEMP | 1450 U17 | Vertical closed | Leaky diodes d301 and weak d302. | Replace with 1n4007 | Heinz |
SEMP | TV DLED L32D2900 | Burning the LED bus. | High backlight voltage, above 80v. the ideal voltage would be approximately 72v. | Remove the first two 0Ω resistors close to the LED connector (cnb801). the voltage will drop to approximately 69v. | JMS Eletrônica |
SEMP | LE3278I | To increase the useful life of the LEDs after replacement | Remove the 0.47r resistors r48 r53 r76 r79 and put 1w resistor 1r0 in place | Original voltage was 47v, putting one resistor voltage goes to 41.5v, if tsound are two it goes to 44.0v | Paial.eletros |
SEMP TCL | 40S6500FS RTK2841 | Burning backlight leds | To lower the current of the LEDs and avoid their premature burning, it is necessary to remove two resistors | Remove resistors rr35 and rr36 from 0 homs | Wtec |
SEMP | 2086MMS U17 | Screen off (with filament lit) | Almost zero screen voltage | Replace capacitor c902 (102k) note: in the test it was working fine. but it was just a matter of changing it that solved it | JS Eletronica (Nilsinho Rodrigues) |
SEMP | TV2134CSL SK11 | Turns on and off after 1 minute | Change the q805, transistor 8050, I put a bd139, and just change the base and collector. | pituka | |
SEMP | TV2134CSL SK11 | It doesn't turn on, I plug it into the socket the LED comes on, the relay hits as if it were going to turn on but it doesn't turn on, the solution is to change the 5v6 zd202 zener diode, next to the micronas, tsound is no 5v voltage on pin 2 of the micronas | Replace zd202 zener diode, 5v6 next to the micro | pituka |
