LCD flat screen stays blank on power up. What's wrong with it?
I have a 42" LG LCD that's about 4 years old now. Every now and then, when I turn it on the screen stays completely blank. I can hear sound, but the screen never comes on. I'll turn it off and on a few times then eventually it will work normally.
It's had this problem for years but it seems to be getting more frequent. Any ideas what it could be?
