What people are saying
Rated 3 out of 5 by from Wifi Problems Used to be a good tv. Latest firmware, 5.80.20, has created problems since upgraded in April. I've seen several others post on same issue. Wifi is turned off with no way to turn on. Even the connection by ethernet disconnects suddenly at times. It is not an issue with my network, as all other devices work properly. How to downgrade firmware?

Regrettably, the contrast ratio for the LG Full HD 1080p Smart LED TV - 43" Class (42.5" Diag), Model # 43LJ550M is not listed in its specifications. Manufacturers do not list Contrast Ratio for TVs anymore because there was never a standard way to measure it...^IFV
