| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SEMP TOSHIBA | TV3489KMS LEM7 | Low sound | C636 e c637 47nf x 25v | ELETRÔNICA MUNIZ BAHIA | |
| SEMP | TV2958GFS LEM7 | When turning off, the logo appears and turns off | Resolder the smd transistor q820 next to the vertical IC, and its entire area. | DJ PITUKA | |
| SEMP TOSHIBA | TV2134 C SL SK11 | It only turns on when it's cold, that is, when it's been turned off for hours, when you turn the TV on and off, it doesn't turn on again, that is, it turns on intermittently | Sach | Replace capacitor 2.2 x 50v put 4.7x100v (c325) close to the oscillator drive | Tião Serra |
| SEMP TOSHIBA | TV2134 C SL SK11 | It only turns on when it's cold, that is, when it's been turned off for hours, when you turn the TV on and off, it doesn't turn on again, that is, it turns on intermittently | Sach | Substituir capacitor (c325) 2 | Tião Serra |
| SEMP | LE3278I(A) | Does not turn on, voltages fluctuate between 12 and 24v | The cause of the problem was the leaky qp5 8050 transistor | Denilson | |
| SEMP | TV2050MAV U17 | Does not turn on, only on standby, secondary power supply 71v | Change without measuring horizontal transistor. q404, even though it was in place, the TV didn't oscillate. I put a d5032 | DJ PITUKA | |
| SEMP TOSHIBA | L39S3900FS | Does not turn on, does not oscillate power supply | Ncp1250 - ncp1250bsn100t1g ci smd from the power supply, 6 pins, 3 on each side, swap and run for the hug! | HAHNRAHN | |
| SEMP | 2134 | The voltage comes on and starts to drop slowly....the relay hits the LED and the LED goes off slowly. | C318 e c319 | Alextecnico | |
| STI SEMP TOSHIBA | LE4050(B)FDA | The TV turns off by itself, when it turns off and on it doesn't show the last channel that was recorded, it shows character errors. | The user data memory is 24c04, rewrite it or change it, in our case we took the memory from an sti card of a slightly different model, it no longer turned off, however the defect in the "no signal" character continued, I believe that with An update will resolve this problem if it persists. | Other valid information is that the 25q64 memory is screen memory, the 24c04 memory is the user data memory, the 24c64 memory is the main flash. | EC |
| SEMP | 2134 | Measure the zd709 diode if it shows a short, remove the ic701 and measure again if the short ends, then replace the ic701 hcf4052be | Electronics line JatobÁ ma org-cicero | ELETRÔNICA LINE JATOBÁ MA ORG-CICERO | |
| SEMP | 2134(B)SL | Knocking relay and it doesn't turn on and LED blinks | Measure the zd709 diode if it shows a short, remove the ic701 and measure again if the short ends, then replace the ic701 hcf4052be | Measure the zd709 diode if it shows a short, remove the ic701 and measure again if the short ends, then replace the ic701 hcf4052be | ELETRÔNICA LINE JATOBA MA ORG-CICERO |
| SEMP TOSHIBA | V2DL2443 | Does not turn on, red standby. | Regulator n805 cx1117a | Replace without measuring. | Antony Garcez |
| SEMP TOSHIBA | TV 2234(C)SL | The TV turned on, then turned off, the power supply voltages were normal. | The 8v voltage was missing from the computer. c725 shorted! | Replace c725 | Chinês eletrônica. Solânea-PB |
| SEMP | TV2934BSL SK91 | Remote control doesn't work. | Replace zd200.5v1 zener diode on the micronas side. | DJ PITUKA | |
| SEMP | TV2090 | Direct fuse blowing | Net power supply diodes and strw so switch and run pro dimdim | ELETRONICA PUBLISOM RGN | |
| SEMP | 1454 (P) SL | No sound normal image | Resistor ruim r604 | Replace of the same | ASSISTEC |
| SEMP TOSHIBA | 32L2400 | The Toshiba logo appears then returns to stand by | After changing the LED bars the defect continued | Update. Tsound are two versions, one with an LG panel, the other with a Samsung panel. | MARIANO |
| SEMP TOSHIBA | 32L2400 | The Toshiba logo appears and then returns to stand by | Update | ||
| SEMP | 1451NAV U18 | League with vertical closed line in the middle of the screen | Bad deflector coil | Replace of the same | ASSISTEC |
| SEMP TOSHIBA | LE3273(A)W | Turns on, it already has a green LED and does not activate power | Changed updated memory but didn't solve it. | Replace u8 ams1117adj (1.5v supply) and replace diodes on the bottom of the board near this u8 ic, position of diodes d1 and d2, I used scrap board diodes with "m7" nomenclature | MIGUELTV |
