SEMP Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SEMP | LC4245 | Works a little and blows the fuse | Capacitor cb910 with leak, shorting out on the vbus line | 10nf 630v | Eletrônica JJ |
| SEMP TOSHIBA | 32L2400 | Turns on, the standby LED turns on, when you press power, the LED turns off but the TV doesn't work, it even stops processing, it doesn't accept functions... if you turn off the power and turn on the power again, the standby turns on but it no longer accepts power, or In other words, it does not turn off the LED and tsoundfore does not start operating. Then just leaving the power out for a long time to be able to power it and it turns on and doesn't work... in other words, a looping. | If in the n807 (1117 v3.3v) this voltage of 3.3v is present, the i.c n801 (fr9889) which is slightly below the processor heatsink is certainly defective. | So, as per the tip sound from the website itself and friends of ours, I also saw the video: https://www.youtube.com/watch?v=_zzaudnxcac and I made the replace and it worked... | MIGUELTV |

| SEMP TCL | 43S5300 | No image | Bad LED kit 2 bars of each with 11 6V LEDs 81cm long | Reduce led current (rr15 of 3k smd was replaced to a 4k7 one) this resistor goes to pin 7 of the ci drive ur01, the power supply was at 70.6v and the power supply dropped to 65v leaving 5.9v on each led ! | orlando lott |
| SEMP TOSHIBA | 2934 | When you turn on the TV, it makes a loud buzzing sound! loud noise as if it were an audio output! | The only condenser capacitor that this TV has was altered (maybe it was from someone else's repair) replace it and replace it with the original! | ||
| SEMP TOSHIBA | TV1450MAV | Red screen with sound and image | 15k open resistor on tube socket board | BICHARA SARQUIS | |
| SEMP TOSHIBA | LC2645W | Noise in sound | Capacitor de 10uf x 25v cw907 na power supply | JDG | |
| SEMP | LC4245 | The lamps blink, and tsound is no 12 and 24 volts, while it works, with a 12v lamp connected to the power connector output, you can see that it is oscillating! | Replace the tl431nw952 and the photo bc904, and also place a 100k resistor on pins 1 and 2 of the same photo, the lamp stops oscillating and the defect is resolved | Rodrigo cofferi | |
| SEMP | LC4055 | TV without audio, with normal image and normal tuning | No sound, r264 (4.7k smd resistor) open or removed (stays on eternal mute) (never eliminate r264 in this model) | Replace a 4.7k resistor in r264 or replace it. audio returned normally (note: the lid plugs must be connected to this TV model to output audio) | Mauricio Nunes - FOCONET |
| SEMP | LC4055 FDA E OUTROS | TV works normally after changing the power supply (card). but tsound is no audio, even when connecting the headphone output cover connectors. (note: without the plugs on the rear cover plate, tsound is no audio) | Without sound and with image remove the smd v204 transistor and jumper the collector and emitter and "only flowers" this is the tip from focanet electronics - mauricio de Salto-SP | Remove/eliminate v204 (smd transistor) and jumper (join) emitter and connector with a thin wire. | Mauricio Foconet Salto |
| SEMP | U19 | Does not turn on, no stand by LED and has ok primary power supply | No secondary power supply | R860 open in primary power supply (220k) | Deo Eletronica |
| SEMP | L40D2900F | Always write and delete | See capacitor eb 80, 39 by 160v from the LED power supply | Marcelo | |
| SEMP | DL3277 I 5800-A8R16B-1P100. VER00.00 | Inoperative with green LED flashing, and after ready, no channels were tuned. | Inoperative was cold soldering on the dp9 diode near the transformer. It's not tuning was what u10 d1117 3.3volts near the channel selector. | Resolder diode even if the solder does not appear cold. replace q u10 3.3 volts | Flad8 |
| SEMP TOSHIBA | DL4077I(A) | The LEDs were burnt out, I bought a replacement, but it didn't light up, the board was also defective | 100k RP80 connected to pin 19 of IC UP4 LED drive | fabiusmax | |
| SEMP/TCL | L43S3900FS | Dark screen only sound | Change led bars reduce current to avoid return it was 88.5v normal is 84v remove r764 1r voltage is 81.5v they are 3v led | Valerio | |
| SEMP | DL4844 DL4844 | Turning off | Replace 3v3 n808 regulator close to two 3w reistors | Replace 3v3 n808 regulator close to two 3w reistors | central audio e video |
| SEMP | TV2134 SKY SK11 | TV with reduced vertical and horizontal frame | It was the capacitors c636,c628,c621,c619 of 1000mf for 16 volts auterated. | I took a look at the capacitors and went for a hug | Eletronica Melo-Boa Viagem-Ceará |
| SEMP TOSHIBA STI | LE 3273 (A)W | Turns on normally, but the backlight does not come on. It was verified that the LED bar was fine, but the 60v output voltage for the backlight was only 26v. | The power supply board was checked and a short was found in the backlight circuit. | Short in the sk3ba smd diode, in position d401. | Eletrônica Video Color |
| SEMP TOSHIBA | DL3945I | Does not turn on, only red LED | Reg 3v3 std by com apenas 3v | Regulator replacement | André |
| SEMP TOSHIBA | MS808MUS | No audio | Tsound was no power supply from the 102 x 1kv CC902 output and str x6759 | Replace the ceramic capacitor and replace the str x6759 with the 6757 because they are equivalent | manin |
