LG 47LE5400 broken main board

[marshman]

These forums have been so helpful to me recently, and I can't thank everyone enough, and now I have my own little problem that I can't find any answers on.

So I bought this LG 47LE5400 damaged. The previous owner tripped over an HDMI cable that was plugged into it, and now none of the HDMI ports work. It was on a single side port, away from the other 3 HDMI ports on the board. It has obvious damage inside the port.

My question is: is the board salvagable? Can the port be either replaced or disabled, making the other ports work?

Any advice would be extremely appreciated. Replacement boards aren't too expensive on e-bay, but if I can save $80-90, I'd certainly prefer to. Plus in the meantime until I get the money, the component inputs work fine.

Thanks in advance!

Maybe if you removed the damaged port from the board it would allow the others to work? could be shorting internally, worth a try

I agree with netdent. It is quite possible for a damaged HDMI connector to cause the others not to work. You will need to be very careful when removing the bad HDMI jack. The pins are spaced very close on those jacks.

For what it's worth, I do not use HDMI for connecting my system. HDMI has a lot of issues, that I deal with on a daily basis as a service technician in the consumer electronics field. When I had cable installed recently, the cable TV installer used component inputs, not HDMI. I asked him about it. He said he does not like to connect using HDMI, because he doesn't like to go back out on install jobs for HDMI issues. I knew right then I was talking to an installer who knew what he was doing!

read some of the first posts in the list, they are called stickies, they have the directions for posting, be sure to put good clear pics. up, you need to start your own thread, because dealing with more than one issue per thread is just way too confusing, good luck.
