SOURCE: Stand-by LED blinks-no picture or sound

the symptom is usually caused by a breakdown in the power supply circuit. in most modern receivers (transistorized and/or ic), it may also be caused by a breakdown in the horizontal deflection circuits (hor. oscillator, pre-drive, or drive circuits). supply voltages for the tuner, video if,sound if, and vertical output are usually supplied by the horizontal output circuit. but if you doesnt know anything about these stuffs, better bring it to a qualified service tecnhician

Not familiar with this particular model of samsung LED TV, but ghosting and shadowing are usually an accepted manufacturer's defect.

If you're still under warranty or within 30 days of purchase, contact the company that sold you the TV or Samsung warranty department.

If you're out of warranty and you don't wish to deal with this, contact a TV repair shop. They will most likely tell you that it's not worth repairing and recommend you purchase a new TV.
