Semp Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SEMP | L43S3900 | League without image. | VD744 diode shorted. | LOGANKLEITON | |
| SEMP TCL | 49SK6000 | Turns on normally but the LEDs from the bad LED print do not light up | Pdin pin in power socket burned out | RJ ELETRONICA | |
| SEMP TOSHIBA | DL3254(A)W | Does not turn on, no standby - primary voltage only | Ci nw907, r913, r914, cw920, cw923 | Tsound was voltage from the primary but it did not oscillate, I replaced the capacitors, checked the 2 open resistors, made the replace and still it did not oscillate, so by changing the ci it started working again. | JADISON - ELETRÔNICA 2001 |
| SEMP | TV2999JMS LEM6 | It doesn't turn on, it just stays on standby, the 130v power supply was missing 9v on the q830 | Change q402 and r415, near the horizontal drive | djpituka | |
| SEMP TOSHIBA | LE 4057I (C) 9235 | Connected but not browsing | I don't know | Wilmar Farias | |
| SEMP | 40L2600 / 32L2600 | STBAY LED on but not turning on motherboard defect; client 8817 | Changing the q101 next to the power supply | Replace without measuring transistor with leak bc558 pnp | marcos melo cascavel ce |
| SEMP | 2177 | Hitting the relay as if it were a horizontal skirt power supply varying TV arming and disarming | Resistor r878 near the str changed | André Luiz | |
| SEMP | TV2134 | Turning off | Turning off and on by itself | Replace of 27k r 218 | gilvan araujo |
| SEMP | 32L1500 | Completely stopped... without standby LED and with 12v at the power supply output, the expected is approximately 6.5v... | Missing 1.2v voltage n801 (fr9889) faulty. | Replace for another. | EVANDOVIANA |
| SEMP TCL | 32S5300 | Voltage of the LEDs at 67v, causing premature burning. | Replace the rr08 of 2r20 for one of 7r5 and the rr09 of 3r30 for one of 5r10. | By exchanging the rr08 and rr09 the voltage from 67v dropped to 60v, as each LED works between 6 and 6.4v the voltage remained within normal limits for the component. | Gabriel G.T. |
| SEMP | DL4045 | Does not turn on, only st-by access | N801 (ci fr9889) inputs 12v does not release 1.15v | Replace.. | Maurilio |
| SEMP | TV1450MAV U17 | Horizontal liters closing on the right side sliced image | C226 estorado | I put a 4n7 | Rogério TV |
| SEMP TCL | L39S3900 | Doesn't start | Broken fountain | Ci power supply driver is em8635, the equivalent is ld7537 | Davi.sls |
| SEMP | DL3277I(A) | Does not turn on, LED goes to green and back to red | Shorted smd capacitor c157 | Replacing capacitor c157 and u14 | LEANDRO VOSS |
| SEMP | TV2034(C) SK11 | Missing the green color: after solving another problem already mentioned in another tip that was already shared sound, the TV turned on, however, with the image missing the green color in the image. | On the kinescope plate (tube), I found the resistor r522 (22Ω) open... and the 3 transistors I resolved the es of this line (q507(bf422), q508(bf423) and q509(bf422) short or open, I changed the transistors and the resistor, I resoldered the board and it failed. | Eletroboy | |
| SEMP | TV2034(C) SK11 | The standby LED would come on, when pressing the on button it would turn off, the LED would go out, the relay kept beating and would not turn on; I noticed that the power supply that feeds the horizontal output went up to 170 volts. | I replaced the photo coupler, tl431, and the transistor q606 and it didn't solve the problem. After researching for a while, I found the c634 capacitor (in the second part of the chopper) dry, (without capacitance) I replaced the damn thing and it solved the problem. | I took advantage and replaced the filter capacitors on the chopper transformer secondary... and those on the horizontal output, they were all with low capacitance... they were still the original ones from the factory. | Eletroboy |
| SEMP | L32S3900 | Does not turn on, just standby on | Nas03 | Replacing the same TV worked | Silimar freitas fortaleza |
| SEMP | DL3271(B)W | It arrived with burned out LEDs, I changed the bars and they kept blinking, LED voltage was 64 volts instead of 74 | Rp 70 next to the icp4, silkscreen on its body 105, | I made the replace and the voltages returned to normal and the LEDs stopped blinking | DTEC-ELETRONICA-Massapê-ce |
| SEMP TOSHIBA | DL3244 | No audio after a few minutes but with audio at the headphone output | Put a 220r resistor on r21 wsound it is without, close to the output | Put a 220r resistor on r$21 wsound it is without, close to the output | Rodrigo cofferi |
| SEMP | 3244 | Turn on the green LED but it doesn't supply 12v, only 7v | Replace the VW971 transistor next to the LED diode | Wesleyborges7 |
