Question about LG 32LB9D TV
I have an LG 32lc56 tv that takes forever to turn on in standby mode we press the on button and light goes out every time red light comes back we press on button and it finally turns green and turns on. But this morning no red light at all tried wiggling power cable at the back and no luck tried using a different power cable and still no luck any suggestions?

Here's a link to the service manual for a slightly larger LG LCD TV. Perhaps it may be of some help? The troubleshooting section appears to be the same for many models of LG TVs...

Whe you press the power button the TV led have to blink several times and the it have to change to blue, meaning Tv is on.
If you press the power button and the led start blinking and goes off, then you need to replace the mainboard because it is damaged.

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.

Replacement power supply is used?
You need to verify the DC output voltages of the power supply first and make sure this power supply has no bad caps with leaking/bulging tops. It goes into standby can also be that it detects fault some where in the set.
Please see my basic troubleshooting guide here:

Capacitors kit: http://lcdalternatives.auctivacommerce.com/Default.aspx he can make you a set of caps.
Or www.digikey.com, just make sure to use caps with low ESR, 105c, high ripple current and long life rating such as PANASONIC FM or FC series.
Please post back what you find.

I had a same problem with sharp LC-40LE340E. The service told me to change motherboard but I decided to buy a new LG TV. The sharp TV I left unplugged for a 50 days and after that when I tried again the tv started normally. I was Really surprised. Don't spend money just wait and check again. email@example.com
