Just a note for those that care ..
Have had 3 Samsung LCD TVs fail recently (2 mine 1 of parents) ... all out of warranty, in each case the PSU has failed.
Also in each case it has been the capacitors that had failed, I guess these are switched mode PSU's and those are hard working caps rather than just smoothing.
Luckily have a good local TV repair shop who replace the capacitors with uprated units, so repairs are not too expensive.
TV repairman advised almost all failures on Samsung are on the PSU .. and although having great screens and display electronics they have very unreliable PSU's ... he feels they manufacture to a cost using parts that will only just do they job, last as long as warranty only.
Although he gets a lot of failures, the faults are usually repairable, whereas Sony & Panasonic faults are often too expensive and therefore terminal.
Just thought I'd mention it in case anybody gets a Samsung TV fail on them.
