We're now starting to see a few Samsung UE46F5000AKXXU led tvs coming into our workshop that no longer start up although they have a flashing red standby light showing there is still power present. Some of these initially had start up problems but would eventually work, but after extended use, then failed to come on at all.

If we can catch it early enough then hopefully we won't have to replace extra components that get damaged, but either way we have now identified and stock the required parts. This is a worth while repair, especially now we no longer need to replace whole pcbs!
