Just when I thought my LG 32LC7D "dumpster find" was without problems I noticed today that there is one. Sometimes when I first power it on, the LED power light goes from red to green, blinks five times as green, returns to red and starts the same pattern over again. Sometimes turning it on and off a few times gets it to work. I took it apart and discovered this:
two damaged, bulging 3300uf/10v capacitors on the power supply board. I discovered this is a typical failure for this model TV. So looks like I'll be doing a electrolytic re-cap of the power supply board.
