LG32LN350B Won't start
Little history on my problem the TV started having to be unplugged to startup every 2-3 days and gradually got worse to the point it would not startup. Currently the LED on the front of the set will flash two times and go out. As I said before when it did this I could unplug it for a few seconds and when I plugged it back in the led would stay on and the set would start up.
So far I have checked diodes and transistors for shorts the fuse is ok and voltages on the PS are as follows with the PS connected.
12v- 12.0
12v- 12.0

24v- 23.5

3.5v-... -

Hi Don from Missouri
Recently retired (3 weeks) ago From the food industry
Was in electronics repair years ago (many years ago)
I have a less than 2 year old LED TV that has quit on me that I would like to repair. so I've been reading all of the forums and learning that I don't know anything anymore.
I would like to post what I have found so far and ask for help.
Love the forums just not smart enough to figure it out
