SEMP TOSHIBA | DL4077L | Don't turn on, green LED flashes | Check ICP1 pin 1 tension (TEA1733) If you don't have 24V, replace DP9 even measuring good. | DP9 (diodo fast 1A) | Junior - Tecnoprom |
LG | 32LE4600 | Normal turns on, when you put any picture power supply (HDMI, AV or Antenna) it disappears the picture erasing backlight, turns off or freezes the picture as a defective screen. | Capacitors C201, C202 and C203 at power supply, 1000UF X10V, in my case they were puffed out. Crazy defect seemed to be a plate | Pedro Igor - Eletrônica Portugal | |
LENOXX | CA-316 | Oscillate | Q8- diode 431 | replace it. | Lu |
SAMSUNG | UN46FH5003G | Don't turn on. Stand-by erased | replace of IC 201 | replace of the IC201 (enters 5V and has to leave 3V). In my case tsound was 2.30V on the way out | Lutec Eletrônica |
PHILIPS | 42PFL5604 | Normal alloy and restart | C804 C805 | 1000UF x 35v | Pardal-x |
AOC | LE39D1440, LE32D1440 | Does not turn on, Standby deleted | No Food in Flash Memory | U702, 1.5 regulator with defective | Eletrônica JJ |
PANASONIC | SA-AKX440 | Disconnect | F703 Bluetooth short, I bought another Bluetooth plate the sound working for 3 hours did not turn off | Solved defect | Andre |
PANASONIC | SA-AKX440 | Don't turn on | Cause was the two TPS54240 shortly, I removed the 2 diodes were good, cause of the burning of this 2 TPS54240 was the IC that feeds USB port, was short, before replace TPS54240, I replaced IC2501 and IC2502 Code AY6397 = BD2242G I switched both and two TPs, sound | Solved defect | Andrei |
PANASONIC | TC55FX600B | No picture+Without Sound | Display, plate | Fernando Cesar Pinto | |
PHILCO | PH32N62 | Voltage of each 6v2 LEDs | R111 , 112 , 114 , 115 do the adjustment , Removi R112 and R115 , Voltage I get 5V8 | Alextecnico | |
PHILCO | PH32N62 | BLACKLITE CALLS 1/2 SECONDS AND SHARES | U3 pin 5 has the R110 (100R) , in place put a jamper and worked normal | JAMPER R110 | Alextecnico |
PHILCO | PTV39F61D | It turns on, but does not turn on the backlight, a power supply for the LEDs is 38V in stand-by and by squeezing Power rises to 44 volts, not enough to light the LEDs, in my case even blinking the LEDs. | Near the output connector for the LEDs has the SMD diode position on the DB1 plate, code on the body of the HBR3100 diode in the short circuit, I used the SK320U instead | After exreplace the short diode, the power supply went to 58 volts, which exceeds 54 volts, the 03 6 LED rules in series are 18 3 -volt LEDs. Then I removed R815 from 2R2 and on the side of 2R4 and the power supply dropped to 53.9 volts. | MIGUELTV |
H-BUSTER | HBTV-42D03FD HBTV-42D03FD | LED lit and doesn't start | D6, R36 (10R), Check U5, ZD2 | Note: replace D6 without measuring | Johnatan |
SAMSUNG | 32T4300AG UN32T4300 | TV calls and shuts off with background light and sound, but without picture | SMD capacitor with escape, C314 on V-Com (measuring in both directions with 10R) | Note: Tsound are 6 capacitors C310,311,312,313, 314 and 315 in parallel have to take everyone to measure. | PEDROZO |
