I have an 11-year old 32" Sony bravia LCD tv. My kids are still using it for their DVDs til this day.
I also have 3 samsung lcd/led tvs. 1 had to be repaired for a forgotten problem after 5 years but still running til this day. The other 2 samsungs are turning 3 yrs old and no problems so far.
Never tried LG coz of "dull" colors.
Oh, our household help's 3 year old 19" myview tv is still running.
