| LG | RP-20CC25 MC 059A | Does not tune channels and does not accept av when connecting the antenna or connecting the cable the av shows vertical lines. | R 512 of 4.7k | Replace | Mauro Mascarenha Tel.( 88 )981422821 Parazinho - Ceara |
| PANASONIC | TC-42AS610B | Red LED lights up and goes out indefinitely, or green LED flashes quickly, goes out and flashes again quickly, voltages at the output rising and falling | Power supply | Cis datasheet in Japanese, the only thing that solved it was interspersing a 10μF smd 0805 capacitor, between the collector of the q7303 and the gnd pin of the c7307, this kept the voltage of pin 5 of the ic7301 constant at startup. | davi.sls |
| LG | RAD226B | Does not turn on, does not light up or standby without 3.7v | Dz901 with leak | Replace 27v dz901 with leak | beto2828 |
| PHILCO | PH24M | Doesn't start | Weak 12v capacitor | Replace the cap, you need to have 12v with 11.8 it doesn't turn on | Matrix |
| PHILCO | PH21US A1 | Dark stripe on the left side | Absence of 0.35 volts on pin 57 of the micro, (afc). horizontal phase. | Replace resistor r487 (12k) | Carlos Alberto (ELETRÔNICA BATURITÉ) |
| LENOXX | MD-270 | Little sound on CD and pen drive - normal radio | R41 | Replace 100Ω r41 on the power supply board | Fabrício (51) 997366096 |
| LG | 47LV5500 | LED stand by turns on white, no sound dark image | I checked the power supply, the normal voltages 12v, 24v, 3.5v, the display LEDs don't light up, I checked the t-con board, 12v is missing, this 12v comes from the main board, measure all the voltages that feed the micro 3.3v 5v 2 .5v 1.5v are normal micro faulty lge35230, I changed this bga the tv worked and 12v appeared on the t-con led they lit up | TV was in test defect resolved | Andre |
