LG37LC2D No power

Good morning, a few weeks ago the red LED on the Tv started blinking when the unit was off. As of yesterday when the TV was off there was no indication of any power. After about 5 minutes I saw it blink once or twice and was able to power it on by pushing the power button on the set rapidly in hopes of catching it and it worked. I left the Tv on all day, but shut it off last night and now it does nothing. I have unplugged it in hopes of some sort of reboot but to no avail. Also the remote stopped working over a year ago, so I have always used the remote supplied by Comcast. In researching this  set it appears that both of these issues are common. I am not opposed to removing the back of the set if I know what to look for. Any suggestions are greatly appreciated. Purchasing a $300.00 part is not an option as there are no funds for that. I would think that LG knowing this is an issue would have something published in the way of a fix??? HELP!!!
