I have an LG 46LD550 that was working great up until a few weeks ago. The HDMI inputs are not working correctly anymore. On the input selection screen the HDMI input (PS3, laptop, Roku) will be an option but once selected I get the "no input" message.

I bought a new main computer board and installed that. I still get the "no input" message but sometimes after sitting on that screen for a little while it will connect and Ill be able to watch Netflix or use PS3. Most of the time it just sits on "no input."

I also tried with new HDMI cables but with no change in the situation.

How can this be fixed? I hate to spend a bunch of money on a new tv if my current one can be fixed for a reasonable amount.

Thanks!
