About a week ago our 3-year-old Samsung LCD HDTV started acting strangely. When powering it up sometimes the sound wouldn’t work. Turning it off then on again seemed to fix the problem. However, over several days the TV started having more difficulty starting up. I could turn the TV on and after a certain amount of clicking relays and blinking lights it would finally start up. Until last night that is, when it didn’t turn on at all. We left the thing clicking and blinking while we ate dinner, without success. I finally just unplugged it.
It’s common knowledge that it’s cheaper to buy a new television than have it repaired. I was understandably a bit reluctant to spend money on a new TV (having just bought this one three years ago) so I searched for the clicking issue on Google. One of the first links was this one. Apparently it’s a common problem for Samsung LCD TVs of this vintage to have failing capacitors on the power supply board. I watched a couple of YouTube videos on the topic and decided I would try to fix the thing myself.
The parts were inexpensive. Four 1000 uF 35V capacitors were $1.59 each at Radio Shack, and I already had the soldering iron. Disassembly of the TV was surprisingly simple, as was removing the power supply board. Removing the bad caps and soldering in the good ones was the hardest part of the whole repair (and even that was still pretty straightforward). After putting everything back together I turned the thing on and it fired right up! It works as good as when it was new, for a total repair cost of under $7. I’m pretty satisfied with the result.

F1 winter testing wrapped up last week in Barcelona, with Lewis Hamilton posting the fastest time at the final four-day test. Everyone always says it’s difficult to determine the relative pace of the teams based on testing times, but it seems pretty obvious that McLaren, Ferrari, Red Bull, and Mercedes are generally at the top with Williams and Sauber possibly up there as well.
The Formula 1 world has seen quite an active off-season since Sebastian Vettel won the final race of the year in Abu Dhabi. To quickly recap the highlights: Toyota decided to leave the sport; Fernando Alonso became a Ferrari driver; Mercedes purchased the title-winning Brawn team; 2009 World Champion Jenson Button jumped to McLaren alongside 2008 World Champion Lewis Hamilton; left without a drive, Kimi Raikkonen decided to try rallying in the WRC; the British GP moved back to Silverstone; BMW sold its F1 team back to Peter Sauber; new team Manor Grand Prix became Virgin Racing; the FIA changed the point-scoring system; 7-time world champion Michael Schumacher made his return to the sport as a driver for Mercedes GP; the Renault team wavered over returning to the sport but decided to stay with assistance from a venture capitalist; and the USF1 experience fizzled-out lamely without ever producing a car.
Of the four new teams for 2010, only Virgin and Lotus have successfully run their cars at the test sessions. Campos appears to be in a position to bring two cars to Bahrain next week, although they will be entirely untested. Stefan GP continues to circle overhead, hoping to be able to run the old Toyota chassis if (or more likely when) one of the teams fail to show up for the first race. As I mentioned before USF1 appears to have imploded, with no car, drivers, or sponsorship. A truly disappointing result for the American-based team. I had personally hoped it would have amounted to more than this.
In any case, the 2010 Formula 1 World Championship kicks off next week in Bahrain. This season is shaping up to be a real shootout, with at least four teams (and possibly more) able to challenge for victory. F1 for me is always a sign of Spring, and since we’ve had snow on the ground since November I can’t wait! Speed Channel (in HD) will be covering most of the races this season with the exception of four races on Fox in the summer. See this page for the updated start times of each session.
