4 red blinks indicates a fan error. usually blowing duster inside the fan blades will cure this. there are 4 fans inside this tv. looking from the back of the tv, the large fan on the left side is usually the culprit...good luck to ya

I had the same problem. Red LED blinking 4 times. This error means that one of the fans is NOT spinning! To check.... unplug the tv.... turn the TV around to a well lighted area so that you can see the fans in the back... plug the TV in and turn it on. Watch for the fans in the back... and see if they are spinning. If not... that is the reason why the TV will not turn on! In my case, the fan next to the lamp was stuck for some reason. I removed the the cover of the TV from the back... and cleaned the fan, made sure all connectors to it were properly connected... and viola! The TV is perfect again! Enjoy!

I have over 10 years experience in electronic tech support.
I know this isn't what you want to hear, but the problem you've described can't be fixed with troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. The 4 red blinks is similar to an error code. It represents what's wrong with the TV to a service tech who knows how to repair it. If you're still in warranty, the TV will be repaired at no charge to you. The warranty would likely be at least one year from the date of purchase from the manufacturer. If you purchased an extended service plan they will repair the TV at no charge as well.
If the TV is no longer in warranty, it will likely cost a minimum of $150 parts and labor. This is assuming that you only need a power supply module. If the problem is one of the video circuit boards, the price of repair could go much higher.
I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.
Please let me know if I can be of further assistance.

There are three fans the one that usually fails is located on top of the optical block and cannot be reached by the owner unless you take the set apart yourself. What is happening is that one of the fans are not spinning fast enough or has stopped altogether. The best solution is to replace all three fans cleaning may not be enough to get a slow fan up to speed, and the tech should blow out the dust in the duct work. This is what the tech coming out will (or should) be doing. Also some fans will have an intermittent startup, and cause this intermittently, so it is a good idea just to replace the fans instead of just cleaning them.
