| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SEMP | TV-2959 | It doesn't turn on, when it turns on after a while it turns off, when the LED comes on in STBY it flashes | Sd19 | Replace without testing, because when testing the capacimeter it shows good | preá- rs |
| SEMP TOSHIBA | 2092 U-16 | When it turns on, the LED turns off, it doesn't turn on and power supplys fail, with the power supply load sometimes it works or doesn't | Vertical output killing 5v after it oscillates | Replace vertical output | WARLEY CESAR |
| SEMP TOSHIBA | TV2015NM U18 | Saturated image in the blue cannon, even with a video signal present. | Change q906 (in short circuit) connected to the emitter of the q905 driver transistor, forcing it to enter a blue screen (blue back) | leitemarcellus | |
| SEMP | TV 2090 E OUTROS | Burning of the horizontal output (bu 808/dfi | Exchanging the same for the same number will catch fire. | Replace with (2sd 1878) replace the 47 x 50v capacitor with a 100 x 50v one, remove the 02 resistors .33r and .47r that are connected to the transistor's emitter and place a ferrite jammer in place of the 2 resistors, also replace the 2sc 1815 and put a small heatsink on the horizontal transistor | Ademar / Videira sc |
| SEMP | TV1452 U19 | Tsound was no second power supply and the LED was off, only 160 volts at the regulator input | 864 diode below the regulator heatsink leaking | Alvanyr This email address is being protected from spambots. You need JavaScript enabled to view it. | |
| SEMP | TV2134 SKY SKY 91 | Sidebar turning off | C634 47/160 dry | Replace electrolytic c634 47/160 | carlosss |
| SEMP | U14 | Image with a predominance of blue as if it were the tube | Q905 (smd) is removed from the kinescope board | This email address is being protected from spambots. You need JavaScript enabled to view it. (BRUNO) | |
| SEMP | 2134 SK11 | Starts and turns off | Replace c/ 634 of 47uf for 160v | Ray Ferreira | |
| SEMP | 2998 | No horizontal synchronization | Replace capacitor c-214 | Ademar / Videira sc | |
| SEMP | TVC-147-CR | No sound, everyone using the ci t-51496 | Change the c-106 connected to the IC pin | Ademar / Videira sc | |
| SEMP | 147CR | I'm sound | Everyone who uses the IC (t51496) replace the capacitor (c-106) connected to pin 8 of the IC | Ademar / Videira sc | |
| SEMP | 1492 U-16 | Blink and turn off the TV | Check q-405 and q-430 | Ademar / Videira sc | |
| SEMP | VARIOS | Constant burning of the vertical outlet ta-8403 | Change c-314 c-315 and r-317 of 7.5r | Ademar / Videira sc | |
| SEMP | TVC-34P | Lack of width | Change q-d04 of the heatsink | Ademar / Videira sc | |
| SEMP | 1033 | Poor quality hoarse sound | Remove q-611 | Ademar / Videira sc | |
| SEMP | 1033 | Blue blurring when the screen increases | Put 390r resistor on the base for the chassis of the (q-906) tube plate | Ademar / Videira sc | |
| SEMP | 2997 | Barrel effect | Replace o c 464 (4.7uf x 100v) | Ademar / Videira sc | |
| SEMP | 2987-CSU LEM-9 | Turns on and off after 5 minutes | Change the resistor (r-470) to 0.27r protection | Ademar / Videira sc | |
| SEMP | 2998 | No horizontal synchronization | Replace capacitor c-214 | Ademar / Videira sc | |
| SEMP | 1021 | Vertical closed | Resolder the q-421 near the LED | Ademar / Videira sc |
