well i know what the problem is... if your getting the white scroll and then the red light flashes but the fans are comming on and you got a new bulb the broblem is the ballast. i know cuz i had the same problem and a good friend of mine has a tv shop and i had him look at it but the good news is that its not that hard to change. if you try to go through LG thay wont be able to sell you the ballast if your just a coust. good news is that you can fined the ballast on ebay from easywaylamps its about $130.00 bucks shiped. bud news about is that thay are from china(it is where i got mine) but it works great and hasent gave me a broblem yet. if any one eles has the same problem and it was something eles.... PLEASE POST IT. i hope my info has been helpful to someone.... thanks Brad Ross of East Moline Illinois

The flashing green bulb light means the access door for the bulb on the lower right side of the TV is open or loose. There are two screws that hold it in. If they are tight, maybe the interlock switch is bad or disconnected. Open the door, and hold in the little white interlock button while turning on the TV. If it still doesn't work, there are wires leading from the switch to a connector about halfway across the TV on the bottom. Connector might be loose. Unfortunately, it is hard to reach. You might have to remove the screws across the bottom rear edge that hold in the chassis and gently slide it out to reach the connector.
