This model has a history of power supply problems. Depending on your level of expertise on electronic repair, you can repair the power supply or replace it. The most common repair is to replace the bulging power supply capacitors.

The main board will have faulty component/s. Seek tech support.

Unplug the power, wait an hour, then plug it back while holding the power button down. This will reset back to factory settings and most likely will solve your problem.

Hello,

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 will help in solving the problem...

its got a bad resistor on the board, it needs to have a fan installed, because its overheating, or the resistor replaced

As with most LCD screens the two most problems that cause black screen are bad a solderjoint on the inverter board or bulging capcitors, the next problem would be most likely the power mosfets witch break down after time.

well my brothers had the same problem you need to unplug it for an hour the turn it back on so it refreshes if it dosent work then Call the help technical support
