We've launched a number of LG main board repair services over the past month and I thought I'd use the blog to update web crawlers and anyone else who cares:

The most common issue for those boards is coming from the main processor, which is an LG branded and enhanced version of the 3549 multimedia processor platform found in many TVs from same time frame , but enhanced with LG proprietary stuff, so no regular 3549 can be used in place of the LGE3549XS or LGE3549XSP ICs.
The issue is not with the chip itself, actually, but with the BGA underneath it, which corrodes and gets detached eventually.
One problem with those boards that was stopping us in the past - and is still a concern for everyone working with them - is that they PCB itself is very tiny and prone to warping under heat.
Now we have a high-end automatic professional BGA rework station - can be seen in some of our videos - which allow for much more precision and reliable operations than before.
As such, it allows us to provide repair services we didn't dare to offer before and at a cost that is actually lower than what we would have done before.
If you want to know if we offer repair for a particular board, just search for it at www.coppelltvrepair.com !
