MONITOR LG C 17 PC - 09
LED just blinked, didn't activate the power supply, monitor didn't work. Capacitor on the five volt line of 1000uf by 10 volts, with low capacity, tsound on the secondary side of the power supply. It was replaced and it worked great. Armando da Eletronica EvoluSom
LG RP-21FE85G
MC-059A
When turning on for the first time, without vertical deflection and insisting several times it works. Change or reprogram ic02 (24c08a) The TV remains without vertical deflection and after several attempts it works correctly. leitemarcellus

Low contrast image Bad diode (d502) on the abl line. I changed it and it was ok. valmirgold
LG 26LG30R
When I turn on the image is all white, you hear if the voice is not the image Friend fabio solution and changing the fusistor on the t-com board, ok and just change it run for a hug If you want more help with this defect, just let me know, my cell. 21 88540816 (hi) we have to help each other. fernando ferreira
LG CP-29K30A
I'm sound Changing the audio processor IC msp-3440g-b8-v3 can also be used without any modifications to the msp-3425g-b8-v3 Ademar / Videira sc
LG 21FX5RL
Without image and sound in (av1 and av2) in normal vhf. Replace ic- la-7958/n Ademar / Videira sc
LG RP20C25
I'm sound Check headphone jack contacts Ademar / Videira sc
LG CP 29K30A
Doesn't work Replace damper diode that is connected to the horizontal output transistor collector Ademar / Videira sc
TV LG 29FE8RL
Turn on and off Check cold welding on jammer 833 of trafo t-801 Ademar / Videira sc
LG TC 2033N
Doesn't work, with little +b on the horizontal output collector Replace the d-825 in short Ademar / Videira sc
LG RP-20CB62
No sync Change or rewrite the eeprom (memory) Ademar / Videira sc
LG 20CB20
Image without contrast Replace zd-501 zener (9.1 volts) and diodes d-501 and d-502 Ademar / Videira sc
LG 21FJ8RL
Turn on and off Change the vertical output stv 9325 or stv 9326 or la-78141 also change the diode d-302 use 2 1n-4007 Ademar / Videira sc
LG 21FJ8RL
Frequently burning the vertical output ci +b with 30 volts that feeds the output, lower it to 26 volts, replace the 1r resistor and place 15r resistors that are on the CI power supply line and come from the fly back Ademar / Videira sc
LG 21FJ5RB
Burning horizontal output and 1r resistor that feeds the +b of the fly back. Change the strw-6753 regulator and the photo coupler, secondary power supply too high Ademar / Videira sc
LG CP-29K35
Burning the horizontal outlet Changing the 27k c-404 capacitor is close to the deflector connector Ademar / Videira sc
LG CP-20K70
Sound I am / sound is the audio Replace diodes d-501 and d-502 Ademar / Videira sc
LG 21FS MODELO NOVO
Turns off intermittently Check the (r-420) 240k open / check the 1r6 resistors in parallel that feeds the +b of the fly back, obs usually has one open, eliminate the q-16 and finally if everything is good add a 390r resistor with the c-409 Ademar / Videira sc
