Picture is fuzzy for the first few mins after turning on


This may be an issue with your color wheel where it isn't spinning up to speed at first but finally does after the 2 - 10 minutes. Fairly common in DLP TV's.
This could be fixed by a qualified Hitachi Servicer.

My new LG LCD TV (3 days old!) suddenly started playing up, last night. I was initially using the receiver unit (with built-in DVD) to play a disc of MPG files, which it did successfully. Then, I tried to...


Good thing the tv is under warranty, theres no magical fix for a problem like this. I would either return it to the store or call for service. If you atempt to do to much to fix it you might voide the warranty, and you should have to do anything to fix it as you said its 3 days old.

The picture is fuzzy and shaped like a hour glass


I had the same issue. The screen would shrink and then expand over and over. After thrity minutes it would correct itself. 
After a few months of doing this it just broke - no sound and no videe but the power light was still on. 

I searched these forums but did not find clear instructions or kits on how to fix it. I gave up and called in a repair tech. He fixed my TV in less than 30 minutes. 

To help others I documented the fix and created a repair kit and step by step quide on how to fix the problem. You can find it here. http://www.magnavoxhelp.com
