|---|---|---|---|---|---|
| LG | LCD | The standibay light does not turn on, it lights up normally as if it were on, it takes a while for the image to appear | Four 1000uf/10v capacitors, it sends 5v to the secondary where it makes the high power supply work | anderson | |
| LG | RP20CC25 | Intermittent synchronism | Two TVs of the same model and with the same symptom, when turning on after a few minutes it would lose synchronization and alternately going in and out of synchronization. solution: resolder the ci 501. | edircap | |
| MONITOR LG | T730SH | No image or it is too dark | Measure screen voltage on g2 on the tube plate, exchange c320 102/2kv and c341 102/2kv | eletronica fernandes | |
| LG | RP 29CC26 | Doesn't work | Faulty horizontal output transistor | Place bu2520dx works perfeitly | alpha eletronica |
| LG | 29FX5CL | Excess width, when you turn on the image it gives excess width | O capacitor c 407 ..aberto ...22nf/400v | Replace do capacitor c 407 22nf/400v | house eletronica |
| LG | CP 14B86 SC023A | When turned on, everything was perfect. Then it gets dark and sometimes it turns dark | D502 (1s2471) | Without it the TV works normally, but it's better to replace it | Santofofo |

| LG | 20CD2R | It turns on normally and after a few minutes it starts to close the sides and turns off. | Ci 802 photo coupler | Alvanyr This email address is being protected from spambots. You need JavaScript enabled to view it. | |
| LG | CP29K30A | Sound and; image with very little brightness increasing the screen on the fly (both on TV and AV) | Q509 with leak, killing the rgb signal in the buffer (q506/7/8) | MAIRES | |
| LG | 29CC25 | Burning transistor horizontal output | Fly back replacement | daniel alves da silveira | |
| LG | RP 29FE80 | When it turns on after 2 minutes it makes a strange noise in the speaker and it turns off and then turns on | Poor contact in the volume and channel board connector | c@rlinhoselectro | |
| LG | STUDIO WORKS55I | Turn on the screen is all green, | Verfiicar trimpot adj.+b c want contato | I adjusted it and it resolved | Eronaldo |
| LG | STUDIO WORS77I | Turns on and nothing lights up, the voltage on pin 12 of IC 901 keeps oscillating, 150vts is normal. | Changed r914 47k and blz | Eronaldo | |
| LG - MONITOR | T730SH CM-54A | This monitor was getting dark and when adjusting the screen it would get a little blurry, but it would soon return to normal brightness, but it would quickly become dark again. | The defect was the ic2476, after changing it the monitor started working normally again. | Moizes | |
| LG | RP20CB20A | Vertical closed | Never trust the test | 470r resistor in position r301 | PALUX |
| LG | RP20CB20A | Vertical closed | Don't trust the test | Altered 470r resistor pos.r301 | PAULO CESAR |
| LG | RP-20CB20A | League,intermittent | Cap.802 short | JACKSSON | |
| LG | RP29CC25 | Does not turn on (stand by) | Shorted horizontal transistor takes together 3 resistors | Q401 / r864 / r865 / r866 | cesar_unitec |
| LG | CP20B85 | Image flickering and colors not defined | Fly back 6174v 8004d leaking high voltage, it was replaced and solved the problem. | Jaison | |
| 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 |
