LG	1642C	Doesn't start	Solution 1replace 3 capacitors on the power supply, but it still doesn't turn on and 3v arrives at the power button. solution 2: bios rewrite
LG	60PN6500 PLASMA	Plate and	Missing 18 v (pulsating)	Fets with fuca and this activates the protection....measure in x1 and 10k one by one....compare with good fet...what will you find....I found several from 42 to 60 inches!	ACTV ELETRÔNICA
LG	50PJ350 PLASMA	Plate and	Missing 18v (it keeps pulsing)	Tsound is a leaky fet....this triggers the protection...measure in x1 and 10k fet per fet....compare with good fets...you'll find it...I've already found several from 42 to 60 inches. ...the 18v are generated by y for the controller and for the z-sus board	ACTV ELETRÔNICA
LG	42PN4600 PLASMA	18v is missing (pressing) on the plate and	The 18v goes from y to the other boards	Is tsound a leaky fet...measure fet by fet at x1 and 10k....compare with good fets...I managed to find several 42 and 60 inch plasmas....if tsound is something wrong, the y board goes into protection !	ACTV ELETRÔNICA
