Semp Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| 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. | ||
| SEMP TOSHIBA | LC1510Z | Washed canvas | U27/d40 c370 e c69 | amram | |
| SEMP TOSHIBA | TV2122 | Vertical closed | Check diode 885 | Sequeira | |
| SEMP TOSHIBA | TS167 TS207 | Jagged image with flyback noise | Check c408 (10/16v) | Sequeira | |
| SEMP TOSHIBA | TS167 TS207 | Power supply low, screen increases, voltage drops | Check r613 | Sequeira | |
| SEMP TOSHIBA | TV2070 | Image closed on the sides | Check q803 | Sequeira | |
| SEMP TOSHIBA | TV1480 TV2080 | No characters | Check ra98(47k) | Sequeira | |
| SEMP TOSHIBA | TV1480 TV2080 | Sound only at maximum volume | Check ra17 (3k3) | Sequeira | |
| SEMP TOSHIBA | TV2092 U16 | Horizontal transistor burns out or heats up too much | Verificar c419 (47/50v) | Sequeira | |
| SEMP TOSHIBA | TVC160 | Image with scratches at the top | Replace c310 (4,7/160v) | Sequeira | |
| SEMP TOSHIBA | TVC160 | Vertical partially closed | Verficar q803 (2sb546) | Sequeira | |
| SEMP TOSHIBA | TVC160 | Power supply takes time to start | Verificar c811 (10/100v) | Sequeira | |
| SEMP TOSHIBA | TV2490 U14 | Power supply with oscillations | Verficar R876 (220R) | Sequeira | |
| SEMP TOSHIBA | TV2090 U13 | Scratches at the top of the screen | Change c308 | Sequeira | |
| SEMP | TV2083FAV U11 | No menu, no volume bar (osd (on screen display) missing) | Rb20 open | Locate the smd resistor rb20 which is at the base of the qb20 and pin 7 of the vertical output. | Helio Eletrosonic |
| SEMP | TV1451 OAV U19 | Does not turn on, without power supply and comulating current | Open 220k r860 and changed 5.6v d876 | Replace | EletroClaudio Aguas Belas |
| SEMP | TV2015MM U17 | Only on standby | I removed the cap. c417 the TV worked normally | note: inserted by ilis drop electronica, I want to say that you were wrong! If you remove cap 417, the high voltage goes into excess and burns the horizontal output, throwing high voltage into the tube and burning it, I mean, we have to be careful with tips, thank you | eletronica do pingo |
| SEMP | TV2090 U11 | Scratched shutter-type screen and missing height. | Ci vertical output defective. | Replace tda8403k | ÁdrianChapadãodoCéu |
