LG 21FU1RLG
It doesn't turn on, the LED doesn't light up and a ticking noise Horizontal output ci q402 d2689 shorted. Replace for another equal or equivalent in my case I put the c6090 and it worked perfectly. I hope I helped. Duliz180
LG 21FS4RLG
Doesn't start Horizontal transistor shorted d2689, capacitor 12n 1600v ruin fly back shorted 6174v-6006h replaces 6174v-6006w and c406 -10k 630v ruin c850 - 1000uf 16v tufted on top, I replaced the TV it worked normally, within 2 minutes it turned off, I turned it on in a few minutes it turned off, as the fly back had shorted on pin +b the resistor fr403 - 1r2 1w test in the digital test it was giving 1r8 it was changed I replaced very close to this resistor 2 transistors q801 and q16 - c5343 with leakage, r420 - 240k changed It was giving 290k c409 - 100uf 16v exhausted c407 - 10uf 25 exhausted I replaced it, solved it, it didn't turn off but Defect resolved Andre
LG 29 CINEMASTER
It didn't turn on, with normal +b and all secondary voltages ok, but tsound was no image or sound and it didn't play the mat or any other flay-back voltage C401 sold out Replace it, and run for the hug! Edfesom Ramos

It doesn't turn on, it just keeps hitting the relay, the large capacitor on the power supply is charged R801 30k altered for 93k Put a normal 30k of the scheme ready and it was good again Biel eletrônica
LG 21FX5RL
Off after a while on R420 c409 q403 After replacing these components, the TV no longer turned off by itself. ELETRÔNICA Power saquaçú
LG 21FU6TL
It just doesn't arm, just standby Ic802 Just replace it Garcia

No image only audio C 483 smd com ysus plate leak Obs I put it with common ceramic 4.7k x 2kv it was fine....... good luck!!!! Jhone eletroonica
LG 32LN540B
It just keeps restarting, showing the lg logo indefinitely. Sometimes it works normally. Cable connections that interconnect the power supply and main PCS Disconnect the cable at both ends and, using a sharp object, press those little windows corresponding to each of the pins. It looks great, you don't need to replace any components. Honorato
LG 21FJ6RB
The TV was turning on normally, but with a sawtoothed green screen, no image and no sound. screen and focus acting Checking the RGB, RGB resistors, 180 cap, normal voltage of 180, good power supply, nothing to replace on the tube board. By changing the tube, the problem was resolved. <small>This email address is being protected from spambots. You need JavaScript enabled to view it.</small>

LG 42LD460
Red LED flashing slowly, +12v with 7.4v, does not turn on Zener diode zd205 (18v), with a small leak, only detected at the 10k resistance level. Replaced the zener diode, and the TV was normal PATRIARCA
LG 21FU4RL
When turned on, the TV starts from high voltage and returns to standbay. C308 broken Replace without measuring. Ferraz

Works for a few minutes and goes into s-protection Defective pc903 coupler photo Replace pc903 SILNEI
LG 32LB9RTA
Keyboard blocked and remote sensor does not respond Capacitor c610 shorted Replace capacitor c610 47pf which is close to the keyboard signal connector and go to the main board and examine the 5v zener which works together with the cap on the connector the signal has the tx nomenclature. ricardovideoesom

Stuck on stand by, won't turn on It is not necessary to open the device. Remove the 4 small knobs (function, effect, file, < >) and the volume knob (large) and try to turn on the device. If it doesn't work, remove the potentiometers one by one until you discover the faulty ones. <small>This email address is being protected from spambots.
