| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SEMP TOSHIBA | TV1415NM U18 | Burning horizontal outlet | Wide capacitor 6n7/1600v. | Changing the width capacitor and not finding the horizontal output | eletronica fernandes |
| SEMP | TV 2121NFS U18 | Dark screen with normal sound (socket) | Changing the kinescope socket | saulo figueiredo | |
| TV SEMP TOSHIBA | 2998 E 2987 | Matte white lines at the top of the screen... | C 308- 100x35 | Perse | |
| TV SEMP TOSHIBA | 2998 E 2987 | Protection acting... | IC 301. Horizontal output. | Perse | |
| TV SEMP | TV2999-KMS LEM7) | Remote control doesn't work, I already changed the infra receiver and nothing. | The defect has been resolved. it was the micro | BF.COLATINO | |
| TV SEMP TOSHIBA | F-74/359A U 9 | TV always has the problem of turning off after about 3 minutes. | I changed the vertical outlet, changed the deflector, tested the horizontal. When the screen is set to normal, it turns off, when I set it halfway, it doesn't turn off, +b normal, I don't have the schematics for it, and when it turns off, it only turns on if I remove the plug from the socket. | I tested the c902 on the screen with the capacimeter and it was good, but I was in doubt and replaced it, and the problem was solved. | BF.COLATINO |
| TV SEMP TOSHIBA | 2958 GFS FS5 LEM 7 | Always 2958 gfs fs5 lem 7 dark screen, screen does not work. | C902, even though I measured it and said it was good, it was bad, I just had to change it and run for the hug. | BF.COLATINO | |
| TV SEMP TOSHIBA | 2157 U17 | On this television "tv semp toshiba 2157u17" I came across a problem in the "menu" of the device's functions, through the control I only have access to "function and clock" and the others, such as "image, audio, adjust" I have no access, nor Even going to the TV panel to access it, I can't do it. | Hotel mode determines the maximum volume the TV can reach, fixes the brightness, contrast and color settings and determines which channel it will always turn on. To access this mode, press the “mute” button on the control and observe the “sound off” indication on the screen. then press and hold the “mute” key and press the “ch-” key on the TV panel for 5 seconds until “hotel mode on” appears. To exit hotel mode, we do the same thing until “hotel mode off” appears. | I disabled hotel mode and thus gained access to all of the device's menu functions. resolved. | BF.COLATNO |
| TV SEMP TOSHIBA | TV2159 | Vertical closing at the bottom and folding. | Ci does everything wrong | Replaced and resolved. | BF.COLATNO |
| TV SEMP TOSHIBA | TV 2091KV U-15 | Star TV, when turned on, turns on the LED and then goes out, the power supply voltage is 0 V. | The cause of the defect was the vertical output ci. tip to discover this defect: with the TV turned off, discharge the power supply's input electrolytic capacitor (the big one that filters the input voltage, normally 170v) then place the tip of the voltmeter from +b general to ground, place the voltmeter on the voltage scale 250v, keep an eye on the voltmeter and turn on the TV. In this case, you will see that when you turn on the TV, the voltmeter will show a voltage of 113v and quickly drops to 0v, this means that the TV worked and then went into protection, normally It is the vertical exit or the flyback that makes the TV depart and go into protection. | BF.COLATNO | |
| TV SEMP TOSHIBA | 2159NFS U-18 | This TV with the sound popping up has audio and it has no quality as if it were a module connected without the remote, this TV is serious, I changed an output, the output is powered by 14v. | Removing the q 906 from the trc board the sound normalized spot blanking transition | BF.COLATNO | |
| TV SEMP TOSHIBA | 2084FAV U-11 | Tv always 2084 fav does not come out of standby. this tv triggers the power supply but does not have high voltage, I found 9v on pin 31 and pin 32 1.8v on q402 c=40v b=0.3 and c=40v and +b is normal . | I went to check the horizontal output and to my surprise it showed that it was running only on the x10k scale, replacing it solved the problem. | BF.COLATNO | |
| TV SEMP TOSHIBA | 2999JMS | This TV wouldn't turn on after changing the regular one 3 times, a new one, cracked, I got a good one and put it in, but the tr q 840 is getting very hot, and it won't turn on, the stand by LED is on but it doesn't start | On the rg 840 transmitter it was 4.3 volts, following the line I arrived at q 841 and after the change the device turned on and worked perfectly. | Conclusion q 801 and q 841 | BF.COLATNO |
| TV SEMP TOSHIBA | TV 2157 U-17 | This television has a dark image, I checked: the abl voltage and are correct, I also checked the hz output transformer circuit (tsh) are also correct. | I replaced the "c902" capacitor with a new one and the image was good. | BF.COLATNO | |
| TV SEMP TOSHIBA | 1021E | It turns on but the frame is reduced and there are some colored lines at the bottom of the screen | Deflector defect | BF.COLATNO | |
| SEMP | TV-1495KM U15 | Stop | Strw 5753 power supply regulator open or broken. After the change, it remains stopped and there is no voltage on the secondary. | R- 876 of 220r open, works on the primary power supply on pin 7 of the strw 5753 regulator. After changing the resistor, the TV was ok. Note: before changing the reg. Check for possible horizontal short. | GEORGE PONTES |
| SEMP TOSHIBA | TV2050MAV U17 | When you turn on normal brightness, it soon becomes dark with a weak image. | Broken track between r227 and d302 | Fix the fault | Elias2305 |
| SEMP TOSHIBA | TV2050MAV U17 | When you turn on normal brightness, it soon becomes dark with a weak image. | Broken trail between r227 and 302 | Fix the fault | Elias2305 |
| SEMP | TV1483 U10 | Doesn't start | 100k r860 open | Component replacement | francion |
| TV SEMP TOSHIBA | 2157 U17R | This TV arrived with bu2508dx horizontal output, | After checking the power supply and peripherals and not finding anything abnormal, I put another bu2508dx on. The TV works normally without any heating, but if I turn off the TV using the remote, a very thin whistle starts and in a few seconds the horizontal output catches fire to the point of burning. | Solved after placing transistor d2624 horizontally.thanks | BF.COLATINO |
