| LG | RP21FE85G | LED lights up when you press ch + LED goes off, hits relay and comes on again and +b goes down | Capacitor c826 1000/16 | S826 1000/16 | APOLO ELETRONICA T.C. |
| LG | RP14CB25A | Vertical closed | R301 (15k) | Replace the precision resistor, 15k r301. | Carloscte |
| LG | 21FU4RL-L | TV turns on, generates mat and goes into protection | 47x16v c308 electrola with high ESR | Sub. by another 47x50v | evandoviana |
| LG | 47SL80YD | Turns on, screen turns off, second goes into protection | High exhaust from the lamps with the housing. | Unplug the connector that goes from the inverter board to the light bulb board, measure possible leakage in relation to the housing with the light bulb board; if tsound is a leak in the connectors; dismantle the screen until you reach the board wsound the lamps are connected; underneath it, an insulator between the plate and the TV housing could have a possible spark point, just isolate it and go for the hug. | TV CENTER |
| LG | RP21FD10 | Doesn't start. When plugged in, the LED lights up and then goes out, accompanied by a rapid oscillating noise. | Diode d802 | I replaced it with a fr156, it worked again. Tsound's no point in putting just anyone, like the 4007. It has to be appropriate. | Romildo Behrend |
| LG | 21FX5RL-LD | It has sound, but no image and all normal voltages. | Turn off the TV, turn the screen to maximum then adjust and turn on the TV... and everything is fine! | jr_TEC | |
| LG | 26LH20R
EAX56856906 | Backlight lamp turning off after 2 sec | Defect on the main board, because with another board it worked normally. | Tracks 2 and 3 were isolated on the flat cable (on connector p402 output to tcom), insulated with *durex*. | FATEC Eletrônica |
