TV Repair Questions? Ask a TV Technician
Okay thank you.
This means that the power supply board in your TV is faulty, and would need to be replaced. The Board is available for around $50, and you can replace it yourself if you're comfortable using a screwdriver to remove the screws on the back of the set, and opening the TV up.
Or if you're not comfortable with this type of repair, then a Tech will charge around $175 parts and labor to replace the supply.
