Once on- no problems
Unit is about 2 and a half to 3years old.

This is a very common problem with your tv, what has most likely happened (about 90% of the time) is the power supply has failed, more specifically there are a few caps in the power supply that have most likely failed. The unit will require component replacement to get it working again. Do you have any electronic repair experience, test equipment, and soldering equipment? If so I can assist you with this repair. If you do not have the above equipment and skills a repairman will be required for this repair, you can expect the bill to be around $200.


I am sorry that I don't have a magic button or a quick fix for you on this one, but component replacement will be required.
