Question about Televison & Video
When switching TV on it seems to continuously loop through the start up sequence, red light, amber light, green light, back to red again...
Switching the unit on and off several times and waiting eventually gets the TV on but will it start at all tomorrow of the next day?

Granger1212 we had the same problem. We called LG and although our LG was out of warranty by 4 months, we were asked to supply our proof of purchase and LG sent a serviceman to our home and in 2 days we had our television back working wonderfully. It's the power supply, call LG and BE NICE, I'm sure they will fix it.

Your power supply board is dead, u know basic electronics’ and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
hope this helps...

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:

Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague
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.
