Question about Televison & Video

1 Answer

I have a Samsung LN52A650 LCD TV. The TV occasionally is unresponsive to the remote. The TV itself is receiving a command and acknowledging it by a beep and a red light but nothing happens. The TV has also turned the volume all the way down on its own even with the batteries removed from the remote. When I unplug the TV as Samsung has instructed but the problem comes back. The problem doesn't happen consistently. I have no idea what frequency the remote operates at or if anything in my house could interfere with the operation of the TV.Other than this small annoyance the picture itself is supperb!!

I'm going to assume that this is a relatively new set and that hte warranty is still in effect. Request warranty service, this symptom suggests either a logic problem in the microprocessor or perhaps just a power supply problem. In either case, this will not be an easy problem to find. One thing that would help is to see if there is any pattern to when this occurs. For example, doe sthe set need to be on for a long time before this shows up? Any info along that line will be helpful to the servicer.

Keep us posted.

Can't power on TV occasionally


It is possible that the conductivity of a power diode is diminished after a period of time causing the unit to receive just under the needed current to function. Test the resistance of internal components after periods of tine or seek manufactures assistance.

Cox universal remote won't control samsung tv ln52a650 volume


This is a tough one, I can come up with possibly 2 solutions, 1 being that if the batteries are low you will sometimes lose partial control of some of the functions on the remote, and if that is not it, then I have another that this one happened to me once, The infrared on the TV was not picking up the volume button I was sitting at an angle, so everytime i sit in that chair everything works but the voulume control i have to point it right at it on direct line and not from the side...Hope this helps...Steve
