LG	RP-20CB25	It turned on and off when the image appeared. If I tapped the channel continuously, the image remained for two seconds and everything was perfect in the image, 100% image. After scanning for a fault in the power supply and horizontal pulse, I began to suspect the micro, as the The TV had shorted out on the strw6753 after a lightning strike via the pay TV cable. Luckily an identical one arrived with a problem in the seletronic due to electrical discharge, I replaced the micro for the one from the TV that had arrived and it was ok	Micro ic 501 (lg631)9r56n1		José Gusmão
LG	RP-29K35A ??????	Turns on normally with sound and image, but then keeps switching direct channels without stopping and increasing and decreasing the volume, re-recording the eepron and nothing, changing the microphone and nothing, changing the crystal and nothing	Remote sensor		ELETRONICA ATUALIZADA

LG	RP29CC26	When the TV was turned on, the vertical one was closed and when the TV heated up, it only opened a small part on the top side, and it kept shaking a lot.	I then checked the power supply tensions which were ok. Then I suspected the vertical output ci, the tda 4863aj, I bought one and before putting it in I measured the pins and compared it with the new one and then I discovered that the 4 to 5 pin of the tda had a very automatic change. Then I just put in the new ci and it was fine, just in case, change the 2 1000mf capacitors for 25v that are next to the ci	If you have any questions, just call guys 33-30842033	This email address is being protected from spambots.

LG	RP20CB20A	Has image + no sound	This model has a headphone jack, which was defective.	I did a jumper on Jack and ran for a hug	fernando timbauba PE
LG	21FJ6RB	Vertical shaking wanting to close	Very critical defect was difficult to discover due to a lot of patience on my part I discovered a polyester capacitor hanging on the main IC cap 512 .474j .63v tsound is no point in measuring it on the capacimeter it measures right imagine! And just put on a new one and run for a hug, God and a hug from you, my technical friend.		fernando timbauba PE
LG	RP-21FE85G	Turns off randomly, after turning it on it doesn't stay on for more than 10 minutes.	Defect occurred after burning fly back and tr.horiz.	When you replace the fly back with a braz alfa and such a defect arises wsound the TV keeps turning off without an apparent defect, with the components that make up the monitoring of the abl being good (resit. and diodes and transistor itself), the value of fr401 de1r2 3w decreases to 1r 3w, the defect will be remedied. It is due to the difference. of res. bras alfa fly omics in relation to the original.	ELETRÔNICA ESTUDIER
