| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SEMP | TV1490 U14 | LED on but not turning on | Cold soldering on r416 and r417 | Resolder the resistors | julio |
| SEMP | TV 2134 BSL SK11 | I got this TV like this, it would turn on and before anything appeared it would continually turn off and forget about it. When I turned on the screen I noticed that the screen was just rich in the middle of the screen without reaching the sides. | I checked primary and secondary power supply sh and sv. everything ok. After a week of almost giving up I found an open inductor at position 200, this inductor takes 5v to pin 22 of the tda processor. I played it, the TV was great.

| SEMP TOSHIBA | TV2091KA | Horizontal output shorted | Substituir capacitor c419(45uf/50v) | Recommendation: check the quality of the horizontal output transistor, use darlington bu808dfx | Luir |
| SEMP | TV-2134 | Oscillates and turns off, killing all secondary tension. I almost gave up on this TV and was amazed when I discovered what it was. | L306 | Replace l306 | This email address is being protected from spambots. You need JavaScript enabled to view it. |
| SEMP TOSHIBA | LC3245F, LC4045F, LC4245F | Locking keyboard and remote control | Check the value of the smd resistor in position r602, itsΩic resistance must not be less than 4k7, if it is below this value the track that goes to r580 must be open. | ||
| SEMP TOSHIBA | LC4245W | Enable Audio out output when using hdmi connection | 1) remove the smd resistors from positions r346 and r347. 2) replace the 33k smd resistors in positions r214 and r217 with 330k smd resistors 3) add jumpers from the positive terminal of capacitors c211 and c212 to the Audio out connector terminal, as detailed below. | technical bulletin | |
| SEMP TOSHIBA | LC3245W LC4245W | Low sound introduces noise in the audio | Isolate the PCI from the chassis, removing the SMD jumpers that connect the PCI ground to the chassis ground. in the position of the m806 screw, next to the tuner there is no jumper, so isolate the fixing screw with the chassis by placing a paper or plastic washer on the top and another on the bottom. | ||
