40in samsung turns on and off before finally turning on LN40A550P3FXZA


Thank you for being Sears’ valued member and for contacting with your question about your Samsung television model LN40A550P3FXZA. I am so sorry it is not powering on immediately. I know the TV is a key part of our daily lives and know you want to get it fixed quickly. In this case, I recommend you have the TV repaired by a qualified technician.

We do not give repair advice on televisions because internal components in the TV can retain a dangerously high electrical charge, even when the TV is disconnected from the power supply. Here at we love to help you with your home repairs but in this case, for your safety, we recommend you have the TV serviced. To set up service go to or call 1-800-469-4663 (1-800-4MY-HOME). 

Thank you for your understanding in this matter. I hope we can help you with any future repairs. Thank you for choosing Sears, we appreciate your business.
