The Lg was disconnected for about a week. I have plugged it back in and it want stay on. The red light is on and it turns green when I turn the tv on but almost instantly goes back to red. Can U help.

My Samsung started doing that and it got worst and worst. Searched the web and find answer. It was the high voltage circuit. All TVs now are like computer and it check for 390 to 400 volts and if it is below, the TV will not turn on. Good thing the Samsung has only one capacitor showing the high voltage circuit. Measure the voltage was 381 volts. The capacitor was rated at 100 uf at 450 volts. From some old TV and power supply, got two capacitors rated 150 uf and 220 uf both at 400 volts. Had to connect them in parallel and took out the old capacitor. Now, my TV works fine.

Here is the low cost solution for it. http://daitechca.ipage.com/store/page3.html

Your plasma TV has a power supply 6709900019A. These power supplies failed due to defective capacitors. See the picture below and check the capacitors mark with the red lines. There are 10 capacitors that should be replaced even if they do not show signs of bulging/swelling on top.
The value of the capacitors is 3300uF/10V but you can use 25 volts as long as they fit in the space provided by design.

lg tv 26lc7d, when I plug the power cord in the red power light cuts on then turn right back off, the tv will not stay on.

Go to a repair centre, some parts must be fixed/replaced.

Did anyone find out the solution for this??????? I have the exact same problem with my LG 32 LCD. I only had it for a year and a half, and the green light blinks a few times and it shows no picture. Not even a red light when the tv is off. The same thing happened a couple weeks ago and by some miracle it started working again.

will turn on tv with remote. stays on green for about 1 second and goes back to red.

When I try to turn the tv on, the green light flashes and eventually goes back to red. A very faint picture came across the tv a few times but didn't stay. The tv is only 3.5 years old.

As long as you have the bill of sale, then you have coverage for the first year from the manufacturer. That's normal coverage with BestBuy.

Hi, I think you have to get it checked out by a profesional, unpluging your appliances is a good idea but damage can also ocuur the moment you plug them back on. If you want to try it could be that a fuse is open there not normal fuses inside (small chip fuses surface mount)
