Brand | Model | Fault | Detailed Problem | Solution | By |
---|---|---|---|---|---|
SEMP | TV 2134(C)SL | Image comes on, then turns off, it oscillates but without image +b low | C613 102k power supply primaria | Replace without measuring | GILBERTO COSTA |
SEMP | DL4845 | TV doesn't turn on, stays on stand by. | Suddenly | Replace the position of the socket wire (rotate it, from left to right or from top to bottom). Mine has been no problem for two weeks now. It worked for me. | adriano |
SEMP | TV205MAV | White stripes at the top of the screen | Vertical circuit malfunction caused by electrolytic capacitor c308 (100uf/35v) | Replace the c308 (100μF/35v) with one with the same capacitance value and insulation voltage! | lucas |
SEMP TOSHIBA | LC4046FDA | Turns on and the screen goes dark with no sound as if it wasn't turned on | Bad main board | Replace main board | Gabriel |
SEMP | TV2134CSL | Does not turn on, LED blinks | 36k precision resistor, close to strw. at the power supply | DJ PITUKA | |
SEMP TOSHIGA | DL3245(A) | Doesn't start. device struck by lightning. | Short in the VDW963 double diode (large diode next to the main power supply capacitor). | Eletrônica R-Tec | |
SEMP | TV1451NAV U18 | White stripes at the top of the screen | Problem is caused by malfunction of the vertical circuit | Check capacitors around the stv9302b vertical IC. | lucas |
SEMP TOSHIBA | DL3975I(A) | The screen doesn't light up | DP15 smd diode near the LED power connector shorted | I placed 02 sr5100 diodes in parallel in the dp15 position | Eletronica Cecé- Brumadinho MG |
SEMP | TV2050MAV U17 | Vertical closed or turns on without image and then turns off | Integrated circuit responsible for the faulty vertical | Replace the ic stv9302a for another equal or equivalent one, in my case I removed the ic stv9325 from the tube monitor board, and the TV worked perfectly again! | Lucas |
SEMP | 2934(B) SL SK91 | Changed power supply, which was supposed to be 133v, was now 151v | R633 changed | CST eletrônica Serrota Senador Sá Ce | |
SEMP | TV1491KAV U15 | Poor linearity from half the screen upwards. narrow weave on the sides. | After working hard on the vertical circuit, changing almost all the parts and re-soldering everything, I found a tip sound on the forum about a similar defect on the same model. I replaced the c884. With this, the TV worked perfectly | Técnico Rodrigues | |
SEMP | 2134(B)SL | Vertical closed with image only from the middle upwards, and with retraction lines. | Capacitor c318 and c319 470nf/25v changed. also change c310 4.7nf/50v | Replace c318 c319 e c310 | MARCONES DE ARARIPINA-PE |
SEMP | U18 | Missing the red | Clear | Gabaglio | |
SEMP TOSHIBA | TV2999 | Annoying noise at the power supply | Swap c819 and c879 | Persio (TVCompany) | |
SEMP | 2934 | Red with traces | In some cases the screen capacitor on the tube plate (102k capacitor) can be replaced by a 104. | Francisco | |
SEMP | TV2934 SK-9 | Does not connect noise at the power supply | 16 volt line diode d306 altered | D306 replace | jean alves |
SEMP | TV2134CSL | Normal plot, sound, and change channels. with an unfocused screen that looks like a rainbow. | Replace d305 ( fr104) and d306 ( ba158) measuring both were good. | Ademit tc | |
SEMP | 2052 U19 | It turned on immediately, turned off, didn't turn on again, only after a long time | Replace of stv 9302a | After replace problem solved | VITURINO |
SEMP | TV2134 | Closing on the sides and turning it off and on by itself, when the sound increases the intensity increases. | Damaged primary power supply capacitor c613 102 2kv | After changing the duct ok. | George Pontes |
SEMP TOSHIBA | 40L2400 | When turning on the green LED, the logo appears and the standby LED turns red without sound or image. | Touched some black l leds. Even so, it continued to turn off, it was no longer the LEDs. | I replaced the burnt LEDs and resoldered the 3.3v regulator, it was cold soldered, resolved friends. | Marinho |
