Recently my 47" LG LCD TV started acting up. No sooner than a month passed and my TV was pronounce useless. All I got when I pressed ON was a black screen and a red power light flashing. The red power LeD would stay blinking forever until I pressed OFF and then it would stay a solid red like most electronics these days. So I made a few phone calls and did a quick research online and found out that it would cost over $500 to fix my TV which just so happened to be a month after my warranty expired. I did some more reasearch and realized I can fix it myself for under $30. The problem with my LG was the capacitors. A quick opening of the back panel will show you if this your problem. I made a tutorial video on how I did it.
Some people are not really keen on even removing the back plastic cover (they probably wouldn’t know how…); some have never seen the capacitor, and some are afraid of lethal voltages inside the TV... or combination of the above.
But for all those who are willing to just give it a try... it can be as simple as spotting the bulged capacitor on the power supply module... at the total cost of around $10 + huge personal satisfaction in knowing: “I did it!”
