I bought an LG 42" 1080p LCD at the local "Household Waste Centre" (aka "the dump".) I paid £20 for it after it caught my eye. LCD panel is intact. Fault description: No power, not even standby power. Open it up... four dead 2200u 10V caps. Easy to repair (about £5 for 9x Rubycon 2200u 16V low-ESR), and it looks like the only fault. Some other caps might need repair.
In a way, I like LG for using cheap Chinese capacitors (SAMWHA brand), because it means broken TVs are cheap and easy to repair. On the other hand... I hate it, because it means that you can't get good electronics these days. The problem seems endemic in the consumer electronics industry, and it doesn't look like it's going to stop.
The fact that the TV is otherwise well designed (it even has surge absorbers on the input!) makes me worry that it comes down to the lowest bidder in terms of parts. Rubycon caps are used for the input filter caps, but not the secondary side. Why??
Manufactured Feb 2007. Lasted a little over 4 years, ridiculous.
