I got a LG LCD tv that I've had for about 3 years maybe more. Recently, I heard a loud popping sound from the speakers and and a slightly fuzzy picture, but now the picture won't even come on at all. There is power going into the tv because the green light is on but there is no picture, I can't even press the buttons on the remote to open the menu or anything. I usually leave the tv on overnight so it may have overheated or something. I've heard a lot of people talking about replacing the caps. Is this the problem?

Re: 42lc55
It's bad capacitors - same with the 42LC46 series - and is an easy fix. Replace the 35V or 50V capacitor on the board (filters power for the audio) as well as the four 2200u 10V.
I picked up a 42LC46 from the local dump and fixed it. Had similar symptoms - wouldn't power up from standby or intermittent power up after left alone for 15-45 minutes.Last edited by tom66; 03-12-2012, 02:18 PM.Please do not PM me with questions!

Re: 42lc55
I buy them and the guys at the local tip keep the money, although it is all on the record (signed book) so maybe they don't?!Originally posted by Jasgriff View PostPlease do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: 42lc55
Jesus!!
Reading this I am glad I didn't let my ego get in the way of the reply I just made on your Samsung post Jasgriff. This had me in stitches!!
Rude and sarcastic, maybe, maybe. The response you received PRICELESS! At least you were upfront and honest.Selldoor - Hi welcome to the forum - I have been told that I am rude and sarcastic so I will try and go easy on you.Comment
