Semp Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SEMP | LC4245W | Audio noise, normal image | Defect in d601 (main board), the diode was open. To facilitate its position, it is slightly below the sound output, close to 2 connectors. | EC | |
| SEMP | LC4245W | No audio, normal image | Defect in the n801 (main board) that generates 5v, the 5v was low and did not generate audio. | EC | |
| SEMP | LC3246WDA KK | TV does not go to standby green LED on | Cause of the defect lack of 5v in the 1.5v voltage regulator IC.. | Make a jump from l801 to l807. Thanks to my colleague Diego Lima for the tip posted. | TV CENTER GUAIBA |
| SEMP TOSHIBA | DL4053 (A)W | Does not turn on, nor does the stand by LED | Measure n805 middle pin with the negative housing, if it is shorted it was already a processor. If it's not shorted, tsound's a solution! | Replace nw910 and nw955 both are shorted primary and secondary power supply sector. I hope I helped!! | Maike Sorriso-MT |
| STI SEMP TOSHIBA | LE4050(B)FDA | Turn on the logo and turn off the backlight, sound is normal. | Tsound is a way to disable the protection of the ssl100sn ci, to do so, place a resistor (1k) from pin 2 to ground, if that doesn't help, also place a resistor (1k) from pin 8 to ground. | EC | |
| SEMP TOSHIBA | DL3244 | TV without image, but had backlight | Defect in the v-com, shorted capacitor was killing the 15v of the avdd, | Replace capacitor c25 with another of the same size | Tec. Daniel Schmidt |
| SEMP | 2134 SK11 | It didn't turn on at all, it just blinked slightly, the standby hit the relay, and it turned off almost instantly, leaving the primary capacitor charged. | (q601) the famous tl431 just change and be happy. | Replace the same. (edfesom:) | EDFESOM |
| SEMP TOSHIBA | LE4056(A)F | Does not turn on; When connected to the network, the green LED lights up and goes out | Corrupted flash memory | Re-record the flash | Julian C Braga (Hitech) |
| SEMP TOSHIBA | LC4241W | Does not turn on, without voltage of 5v and so on, does not hit the relay | Capacitors c866, c842, c843 all 22uf/50v open | Touch the same | Julian C Braga (Hitech) |
| SEMP TOSHIBA | LC3246WDA | Does not turn on, LED changes from red to green, but no image | Power supply without 12v and 24v | Check resistors around the IC of the NCP1653A PFC, to facilitate identification, measure the voltage above each one, equal resistors in series must show the same voltage drop, so an altered resistor is discovered, most of the time it is the glue under the resistor , you have to remove and scrape the glue! | Lucas |
| SEMP TOSHIBA | TV2959 | Low sound | 2 47/25v capacitors next to the sound output | Marcondes Ohm Eletrônica Jaicós PI | |
| SEMP TOSHIBA | 42RV700FDA | Screen lit, but washed. | An open dc/dc coil on the t-con | Re-soldering coil terminals | Jump Eletrônica |
| SEMP TOSHIBA | TV2083 FAV | TV closed top of screen. It opens as the TV heats up. | C 305 1mf x 50v | Just replace and run for the hug. | NEW PEK ELETRÔNICA |
| SEMP TOSHIBA | TV2134 | Red tv with retrace lines with normal sound | 15k red pin resistor heating up tube socket defect | Lincam Bezerra | |
| SEMP TOSHIBA | LC3246WDA KK | Green LED on does not turn on. does not release screen. | Capacitor c805 100uf/16v shorted. | Replace ok | Wil |
| SEMP TOSHIBA | DL3271 | Screen with vertical scratches and screen half with scratches and the other half working. | Tsound were two televisions: the TCOM was changed on both, and the defect remained exactly as it was. screen defect. | Were returned due to lack of parts to buy (the screen in this case) | margutek.bva |
| SEMP | TV1450 U17 | Blank screen with no image | Ca40 when I went to resolder the computer it paid a lot of attention | Ca40 if it happens | Rogério Tv |
| SEMP | TV2134BSL SK11 | Turns on the relay and turns it off, otherwise it turns on normally, turns on and off | Replace without measuring cap c636, 1000x16 | DJ PITUKA | |
| SEMP | 1483AAV U9 | Totally dead | Open 100k r 860 replace feeds the 18v12v in pin 4 of the ci strf5653 | elet sto ant riachão do jacuipe bahia | |
| SEMP | TV2134 | White screen with retrace lines | Tube plate 180v open thread resistor r308 | Eliel Magno |
