Hello everybody.
A message appeared on the TV that new software is available. I clicked update. Downloaded and updated everything is fine, but after rebooting there is no invention on the TV. The red color blinks 4 times, and so the cycle repeats. The remote reacts.
Forgive help from anyone what ideas.
Model: LA40C650L1R
Model Code: LA40C650L1RXCS
M/B: BN94-03501X (BN41-01443A)

Bad news. Usually such failures end with mainboard replacement. Appologize.

"New software" for C series??
Sounds like "time to buy a new TV" Samsung decided...

Well, what to do next time I'll be more careful. The question is, what kind of mainboard can I get? since did not find the identical. Help with advice please.

if you can't find exact same model (BN94-), one having same design (BN41-) should fit.

was purchased mainboard from LE32C630K1W, installed everything works fine. Thanks to everyone who participated in the discussion
