LG Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| LG | RP-21FD15 | Inoperative. | The LED lights up, when executing the command the LED turns off, the TV does not oscillate and returns to stand by condition. | Cold welding mainly on the power supply, regulators and vertical circuit. | Elisson Aragão |
| LG | RP20CB62 | It doesn't turn on. When we try several times, it turns on but is stuck on one channel, not accepting any commands from the CR or the panel. | Change eeprom|(24c04) and program setup parameters | ELETRONICA ESTSUDIER | |
| LG | RP14CB20A | Vertical with height deficiency (I noticed that the sides varied when the image changed) | I verified that the power supply +115 the 47/160 capacitor had low capacitance | By changing the vertical capacitor it was normalized | fernandocamarques |
| LG | CP14K42 | It fires when it turns on then turns off (note all voltages are present at the moment it fires) | Defective vertical output (la7833) note tsound is no point in removing it from its place, the ap only works with it in place) | fernandocamarques | |
| TV LG | LG.29FS4RLG | X-shaped screen or non-standard convergence | Replaced or capacitor c 461- 0.047 uf 630 votes capacitor exhausted | jaironuness | |
| LG | RP-20CB67 | TV just stays on stand by, similar symptom to defective PC | Moisture between the micro pins | When you have this device, you suspect the computer; before changing the computer, remove it from the board and wash the computer, thoroughly to remove dirt between its pins. | Roberto Consertos |
| LG | RP21FE85 | When the device is cold, it does not turn on | Crystal x1 and cap. c11 and c12 (both with escape) | Replace them next. to ic501 | MAXWELL ELETRONICA |
| LG | CP14B85 -------------------- | Contrast function did not work | Position resistor 550 (10k) open | Replace resistor position 550 (10k) | Clayton |
| LG | 710E MONITOR 17`` | Dark image | In addition to the other one I already wrote, I got another one with the same defect, but this time it was the ci of the kinescope plate | Replace the ci | AdrianChapadão |
| LG | RP-21FE85G | Turning off | Rr420=240k, | http://rmeletronica.com.br | |
| LG | CP 14B86 | Contrast does not work, without contrast | 502 diode shorted or leaking | willamis | |
| LG | RP-29FA30A MC022A | No plot and no sound | Tv lg flatron rp-29fa30a was without plot and without sound. when pressing the power button it produced an intermittent hiss...like tshhh.....tshhh.....in the tsh collector tsound was also an intermittent +b, varying between 110v and around 70v. It was possible to observe that tsound were some voltages originating in the fly-back secondary, quite reduced and also varying, but tsound was no voltage at the screen output, which indicated a defect in it. Replacing the fly-back with one from Brasalfa, the defect was resolved, but the weave was excessively wide. After checking that tsound were no damaged components in that circuit, it was enough to enter service mode and make the correction. (One way to enter the service mode of this device is to simultaneously press the menu keys on the remote and on the TV panel for + or - 10 seconds.) | littlecarlos | |
| LG | RP 20CB25A MC 059A | I'm sound | Memory 24c04 | Replace memory 24c04 horiginal | luitvsom |
| LG | LM-M730A | Weak audio (fanho) | Stk 412-290 | Subtitle it | J.DANTEX |
| LG | MC-59K - CP-29C84M | No on-screen functions (OSD) | Diode d401 in surge | Replace diode d401, also check c402,c401 and follow the line. res: lack of pulse h | caio |
| LG | CP20K40 | When turned on, the TV turns off in less than 2 seconds | I changed the processor. str6654, but it didn't solve it, it keeps turning off | Then I decided to replace the memory (24c04), it was shot and dropped, it didn't turn off but it remained file, it was the memory that was the defect | This email address is being protected from spambots.

| LG | LH-D6235A | Cooler doesn't work | Apply thermal paste to the th300 thermistor and place it against the heatsink. | Persio | |
| LG | 21FS4RLG | Normal and completely dull sound | I opened the jamp l-901 from the skrin grid and turned on the TV and it worked, then I just put the l-901 in place and that was it. | Alvanyr | |
| LG | RP20CB25 | Image without contrast normal menu | Diodo d502 1n4148 | Edson Peixoto | |
| LG | RP-21FB32 | Oscillates and cuts quickly and kills the 10 v voltage | Just change the flex blah because tsound is a problem. | maicon |
