| SEMP TOSHIBA | 42HL57 | TV without sound and LED image activates Note: after several attempts, the TV returns to working normally. When turned off for a long period of time, the defect appears again. | C862 2.2mf changed | jorge luiz mantini | |
| SEMP | LC3246WDA | I'm sound | Does not amplify audio | V 208 smd transistor on the bottom of the pci | Alvaro (prolar) |
| LCD SEMP TOSHIBA | LC 15/2010Z | The power supply does not start | Check on the PCI main stage of the power supply if the electrolytic capacitor c356 is altered or has unsoldered terminals. | Capacitor/ c356 | xmichaelx |
| LCD SEMP TOSHIBA | LC 2010Z | The device turns on, the display lights up and then turns off spontaneously, activating the protection. | C30/ c31/ c32, approximate voltage value across the capacitors, c30 15v/ c31 19v/ c32 19v. | Check the inverter circuit, in the protection stage, if the capacitors are shorted; c30/ c31 /c32 / 100kpf. To turn off the protection, it short-circuits the collector and emitter of transistor q9, and damages whether the device works normally. | xmichaelx |
| LCD SEMP TOSHIBA | LC 15/2010Z | Display without video (all white screen) and normal audio. | Shameless/D40/Saah0/Saats | When they noticed on LCD televisions models LC 15/2010z, display system without video, completely white screen and normal audio, located on the main PCI a/d. check: u27/d40/c370/c369, detected most frequently (d40) with leak. if the u27 regulator voltage was below 9vdc: completely white LCD screen. | xmichaelx |
| SEMP | TV2091 U14 | TV with squeaky power supply | Flyback | Replace the flyback | xmichaelx |
| SEMP | 2071M NãO TENHO | TV only has light on the screen. Tsound is no sound or image. | I've worked with TV repairs, but it's been more than 15 years. This TV is mine, I don't have a schematic for it. | jose de matos | |
| SEMP TOSHIBA | TV 14 OU 2091 U14R | When turning on the TV, the LED lights up for approximately 5 seconds and then turns off. After this procedure once, it no longer lights up, only after a few minutes. I tested and replaced all c3209, fly back, power supply capacitors, no solution. | I only solved the problem by replacing the stv9302 vertical output. obs. "I used tda9302 and it worked perfectly." | Carlos Guerra | |
| SEMP TOSHIBA | TV-2084 | Image with ripple and escaping synchronization | C404 - 0.47uf broken | Replace it even after measuring ok! | stiltec |
| SEMP | 20A82EAV U8 | Vertical closed at the bottom with retrace lines | C301 1mf/50v | Replace to solve | haecio |
| SEMP | TV2959IFS | TV doesn't turn on | When you turn on the TV, +b appears and then disappears, measuring d885 you observe a small voltage spike, which disappears then, but this voltage spike does not appear after r 885, so r885 is open... | Replace the r885 resistor, "obs" the resistor is 0.33 r, I put it at 1r and it's cutting high.... | Ricardo Alves / Eletrônica do Ricardo / Caeté MG |
| SEMP | TV 1450 U18 | Vertical closed or closes intermittent | Ya 430 is zener eat intermittent | To replace | Alvaro (prolar) |
| SEMP | 2090 E OUTRAS | Sem osd | Change the memory ic | Master Eletronica | |
| SEMP TOSHIBA | 2090 AUV14 | Turns on normally after two minutes, turns off and turns on again, then stops and keeps chirping horizontally | Ci 801 with faults | The c i tv was replaced | euripedes |
| SEMP | TV 1491 U14 | Does not turn on, stays on standby | Does not start horizontally | Capacitor c887 | juares |
| SEMP TOSHIBA | LEM5 | Naõ sai do stand-by | Vertical ci shorted and r327 open | carlinhos100 | |
| SEMP TOSHIBA | U9 | Image folding at the top | Faulty vertical ci. | carlinhos100 | |
| SEMP | TV1452 | It doesn't work and the LED keeps flashing and the power supply only has 55V | 10k 865 capacitor shorted | Replace for a good one. | Ademir solânea pb |
