It sounds like defective capacitors in the power supply/inverter. Unless you are experienced in electronics be careful repairing. Check for bulging electrolytic capacitors, bulging capacitors indicates they are defective. But a bad capacitor doesn't always bulge to indicte it has failed. Replace all cheap capxon capacitors, with low ESR rated capacitors from Digi-Key, Mouser, Allied electronics or Newak electronics.
HiThe problem is faulty power supply, because of leak capacitor that's why the output voltage is cut off. The leak capacitor can identify through visual checking, the leak capacitor have bulging tops.Just remove the cover and find the power supply located at the upper right and you can see the bulging tops capacitor.Replace with the same value of capacitor.
The problem is in the logic board of the LCD television at the vertical section.There's a leak capacitor or bulging top or faulty vertical driver ic.Replace all bulging tops capacitor at the vertical section at the logic board with new capacitor with the same value.Thanks..
Bulged capacitors are blown, that is the reason why the motherboard do not start.
Sometimes replacing capacitor may fix the problem, but due to the inexpensiveness of motheboard, and to the chance that more component may had been damaged by the fault, when this happen you usually replace the motherboard, rather then repairing at component level.
Yes, I can tell you that when the capacitors start bulging the you will need to replace the device. This is a sign that the capacitors are starting to fail. Now if you can put in a fan somewhere that will kept the heat down then you might be able to use it a little longer. You have got to get the heat away from the mother board.
Yes, he means 2200 microfarret (called uf from here on out). Another important concern when buying a replacement is the voltage. You need to get something that is at least 25v. I recommend a 35v or better. Another notable point is that this may not always fix the problem. As with mine, there was also a 1200uf (microfarret) 35v capacitor that was blown. You can tell this because they bulge at the top. I have both of these caps (2200uf 35v and 1200uf 35v) on order and they will be here tomorrow. If I do not post back here then they fixed the issue for me. I suspect that this will resolve the problem. Look for bulges on top of the caps. This is an indication that they are blown. Most all of you experiancing these symptoms will see the 2200uf cap bulging but you may also see others bulging too. If you do then you need to replace those too. No electrolitic capacitor should be bulging at the top so if its bulging its bad, and if its bad then your tv will definitely not work. Have fun.
