Question about Samsung LN-T4042H 40 in. LCD HDTV
I have a samsung lnt4042hx/xaa 40in lcd tv and for a while it was, what i think ppl call, cycling. making clicking noises and taking a long time to turn on until it finally did. now it wont turn on at all just clicks once but nothing happens. ideas before i take it in?
I concur with Lightnbaby.... had same problem... my TV LNT4042HX/XAA took 10 min to start sometimes... the capacitors on the power supply board had bubbles on top 4 of them all 10/1000Uf. Samsung wanted to charge $220+ to have a guy come out and fix. J&J parts (samsung vendor) wanted $108 for a new board. I replaced the 4 capacitors for $4.68 and the TV works fine now!!!!!

Just an FYI: I called and Samsung is sending a repair tech out to replace the Power Supply for free as part of a Class Action lawsuit:
