| SEMP TOSHIBA |
TV2134 C SL
SK11 |
It only turns on when it's cold, that is, when it's been turned off for hours, when you turn the TV on and off, it doesn't turn on again, that is, it turns on intermittently | Sach | Replace capacitor 2.2 x 50v put 4.7x100v (c325) close to the oscillator drive | Tião Serra |

TV2958FFS FS3
LEM 7 |
Image with excess width and cushion effect and does not regulate dpc or width, i.e. does not regulate horizontal | R 335 | R 1k at 335 | Tião Serra |
| LENOXX |
CA-311
|
At first we thought the pre's were bad because when we removed one of them the sound improved but it wasn't good, it kept popping a little. | C32 of 220uf/25v from the -12v power supply was completely dry | Replace c32, and check if tsound's anything rusty. | AR Eletronica |
| GRADIENTE |
TF2151

32LE5300
|
Turns off the backlight by itself after a few minutes on | Reformulating the previous tip; Looking a little more, I found the cause of the defect. It is the zd7 diode (it is a double diode) on the inverter board that is defective, it regulates the 3v3 voltage of the driver on and dimmer pins. put 2 3v9 zenner diodes in its place. | EC | |

Turns off the backlight by itself after a few minutes on | If the backlight LEDs are working perfectly, check if the voltage entering the inverter board at the drvr-on pin drops from 3v3 to +/-2v when the backlight deactivates. | If the driver-on pin voltage remains at 2v2, short the side pin (PDIM 3v3) to the driver-on, thus forcing the backlight to remain activated, it is likely that the defect is caused by the main board, some component on the Defective driver on line. | EC |
| SEMP |
LE3278I(A)
|
Does not turn on, voltages fluctuate between 12 and 24v | The cause of the problem was the leaky qp5 8050 transistor | Denilson | |
| HBUSTER |
HBTV-29D07HD
|
TV turns on normally, after a few minutes on it loses the video signal and turns off but the LED stays red (stanby). | I changed the memory ci and it didn't solve it, finally I changed the regulator (u8), 1.5v and the problem was solved. good luck . | ||
