| SEMP TOSHIBA | LC4247F(A)DA | Does not turn on, green LED flashes 3x | 3.3v line shorted | C9015 and c9013 replacers | Lucas |
| SEMP | 2050MAV U17 | Overheating horizontal transistor | Lack of a heatsink | Just put in a heatsink and it no longer overheated. | Antônio |
| SEMP | TV1484 U13 | No sound normal image | Remove resistor 330k position on board r606 | EletronicaAlmiro | |
| SEMP TOSHIBA | 14 U15 | Does not turn on or off on the control. | Change without measuring the c887 (100uf/25v) | NATO ELETRÔNICA | |
| SEMP TOSHIBA | DL3975(A) | Does not turn on or stand bay power supply pulsating | Shorted power mosfet, open dz202 and brown fuse near open mosfet | Replace them and put the money in your pocket. | M.zidane |
| SEMP TOSHIBA | DL3975(A) | Does not turn on or stand bay power supply pulsating | Shorted power mosfet, open dz202 and brown fuse near open mosfet | Replace them and put the money in your pocket. | M.zidane |
| SEMP TOSHIBA | TV 2134 (CSL) | Alloy with closed vertical + or - 3 cm. | The problem is in the vertical ci utc 78045 itself. | Replace vertical output UTC 78045 (substitutes: AN5522, TDA8172, TDA9302, STV9302 and LA78040. The best option is STV9379A | Robson TALL TEC Eletronica. |
| SEMP | DL4061 | Turns on backlight but no image | 17v CD5 line ceramic capacitor 10uf of fixed tcon board on lcd | Emerson | |
| SEMP TOSHIBA | TV 2134 (C) SL SK 11 | The standby LED does not light up, the normal power supply, the horizontal oscillator does not arm and tsound is a lack of 3v3 volts on the processor pins | Change c622 470mf 16 volts in my case it was shorted killing the voltage | Marcos Eletromad Cláudio MG | |
| SEMP TOSHIBA | DL4845 DL4845I | The Toshiba symbol appears and turns off the screen | One of the modified LED buses | Replace complete bus - replace r766 from 5k1 to 10k (reduces circuit sensitivity, avoiding blinks) - remove six 2r7 resistors (r787, r790, r797, r794, r723, r782) this reduces the bus current, increasing the useful life of the LEDs | RUBERVAL SBC |
| SEMP | 40L2400 | TV doesn't turn on, light is off. | Main board, check on the second river if the 6v and 50v voltages are present, if so, the converter is defective. | Replace dc dc converter n802 ( fr9889 ) smd 8 pins. | RNSPTEC |
| SEMP | TV2134CSL SK11 | It doesn't turn on, the relay hits twice and it doesn't turn on, and the stanby LED stays off straight away, the power supply stays at 145v, the 3.3v voltage stays at 3.7v. | Change ic201 micronas | Dj pituka | |
| SEMP | 2134 SK11 | The TV couldn't start, the screen was completely dark even when the screen was raised, and it was constantly restarting all power supply voltages, ok, pulse signals, ok. You already see them missing. I found the voltage of 5v that powers the computer with 3.6v. | After changing the micro ci and the symptom didn't change, I released the 733 jumper and the 5v came back on the q606, I decided to loosen each piece connected to the 5v line so I got the ci 801 (btsc stereo decoder) shorted. | Replace ic801.
