| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SAMSUNG | UN32C4000 BN44-00349 | Turns on with sound. no images | The cm806 capacitor had a voltage of less than 8 volts and was oscillating. the transistor qm 801 was shorted and the qm801 (q0765r) without pwm, I just had to change them and the voltage in dm871 appeared and in dm874 oscillating I replaced the cm872 capacitor and everything went back to normal | EPINFOR.COM | |
| SEMP TOSHIBA | LE2458(A)F | Stopped, with LED alternating between green and red. | Mosfet me15n10-g in position v701 "bottom of the board".... diode sk3b in position vd751, top of the board. This diode is a schottky barrier 3a/100v, failing that I put an sb3200 3a/200v. good luck . | This email address is being protected from spambots. You need JavaScript enabled to view it. | |
| PHILIPS | 29PT658A L01.1L | No vertical scan | Diode 6487 (byd33d) leaks, opens resistor 3488 (4r7) and burns the ci tda8359j. unload the electrolytics that power this ci and now replace these components. Instead of the byd33d diode, you can use the byv95c. | Isidro | |
| PANASONIC | TC-L32C5B | Dark image, after a few minutes it turns off and the red LED flashes once | When I opened the panel, I saw that the lamps were only half on, I replaced the power supply board, solving the problem. | ANTÔNIO ZWIRTES | |
| TOSHIBA | X40/X41M | Inoperative. normal power supply voltage but display off and mechanics not working | 100k r820 open in the ac clock circuit (pin 13 of the power supply connector) | ||
| TOSHIBA | LC4241W | Tv inoperante led stand by apagado +b 5v ok. | Verificar capacitores c866, c879, c844, c842, c843, c832. | Verificar capacitores c866, c879, c844, c842, c843, c832. | samuel leite |
| SEMP | TV2934 | Inoperative stand bay ledy does not turn on and the power supply capacitor is overcharging! | R602 | Replace the 68k r602 | Sinailson furtado |
| SEMP | TV2934 | It doesn't turn on, it just makes a noise at the power supply as if it were the horizontal outlet that had failed | D302 | Replace the d302 and the TV will work normally. God be praised! | Sinailson furtado |
| PHILIPS | 47PFL7403/78 | Power supply/backlight test | Soldar stby com gnd - soldar resistor (1k 1w) 12v no bl_on/off - soldar resistor (4k7 1w) dim no 3,3v | Cláudio Negrini | |
| VISIONTEC | VT1000 SMART | Receiver does not provide voltage at the ac output | If everything is ok with the 7812 regulator and the relay, replace the q1 b985 | ELETRÔNICA POSITIVO STA. LUZIA DO PARÁ | |
| BENQ | MS513 | Doesn't start | Ic611 burst | Replace ic611 top258pn | ser-mga |
| SEMP | TV2934 | It doesn't turn on, it just makes a noise at the power supply as if it were the horizontal outlet that had failed | D302 | Replace the d302 and the TV will work normally. God be praised! | Sinailson furtado |
| SEMP | TV2934 | Turns on normally but after a few minutes the TV starts to flicker to the sides and the TV turns off! | Q606, | Replace the q606 br8050, replace this transistor with the bc547 in reverse. God be praised! | Sinailson furtado |
| SEMP | TV2934 | The TV turns on but the relay does not help and the TV dies. | Tube, r304 | Replace the image tube and the 1k r304. God be praised! | Sinailson furtado |
| SEMP | TV2934 | Forced switching on | C311,r322 | Replace the c311 of 47µf/250v and the r322 of 22kω | Sinailson furtado |
| SEMP | TV2934 | Alloy with pylon waist fabric | C304,c301,q302,c311 | Replace 0 c304 the TV will turn on normally but with the expanded screen replace just replace the c301 the screen will be normal. But after a few minutes of operation, the image recedes and the screen becomes expanded, just replace the q302. God be praised | Sinailson furtado |
| SEMP | TV2934 | Japan Fund A Nishida Horizon et al. | L01, S05, S06 | Replace the coil l301if the coil is heating up a lot, just replace the c305 of the c306! the value of coil l301 is 790μH. God be praised | Sinailson furtado |
| PHILCO | MSS MSS | With normal image only at the bottom - everything is dark above | Causing the electro capacitor - 303 of 470.uf - close to the vertical ci- | Just replace and move on to another cucumber - resonant electronics claudia mt- | Raimundo damascena |
