LG	RP21FD10	TV with stand by blinking.	D810 open. After changing, the LED stayed on, however, when I pressed the power key or channel + and channel - the TV did not turn on, so I analyzed the power line and found the c826 de2200ufx16v with low capacitance and it was just a matter of changing it and it started working again. normal.	Another xausabde stand by led off or flashing is the control's infrared receiving photodiode open or shorted, so do as indicated and move on to another	Jailson Lima
LG	CM8440	Volume above 30 the audio stops for 7 seconds and returns	Pfc voltage is 380v, but it only had 364v, I found the smd resistors (r917, r918, r919) changed, the 3 are 1m	I replaced the 3 1m resistors, in my case, this solved the problem.	C-audio eletronica (SM-AL)
LG	32LK330-SB	Tv was admitted, coming from another assistance wsound the t-con.tv board had been condemned to be completely inoperative! When opening, I disconnected the flat (pci main/t-con) and the TV turned on, tsound was sound but, of course, no image. the t-con fuse was open, when replacing it, it burned again... carrying out a quick visual inspection and continuity test on the smd capacitors, I checked the capacitor in position c31, in the dc/dc circuit (t-con ) shorted.	I removed the capacitor and replaced the fuse. The TV turned on again and had no problems. I chose to leave it without the capacitor under test and it continued to work perfectly until delivery to the customer. A big hug to everyone and don't forget to post repair tips, this is one of the best tools for the technician!	Removal of capacitor c31 on the t-con board (dc/dc power supply), shorted smd. circuit worked fine without it!	AnisioH
