Lost commuication between the remote and the TV, I changed the remote's batteries and reprogramed the remote and still not working can you assist.

If you took the batteries out of your remotes to change them, they possibly lost their programming and need to be reprogrammed. I drop my controller often and have to reprogram it. All of the lights light up but the TV appears dead. Either find your control programming guide or look it up on the internet how to reprogram your remote.

need to know the model of the DVD player and remote to be able to further assist you...but a quick google search with that model # and the phrases "program codes" and "how to" should quickly bring up a how to article or manual for the dvd player with reprogramming instructions.

you have to replace the IR sensor you can order at ebay.

tried with reset doesn't work, ok it could be the IR sensor at the front panel of the tv doesn't work. but before you replace it you need to ensure if your remote controller is working. have you tried to check the remote with camera trick just to know if the remote controller is sending light to the IR sensor of the tv.

The remote may have a bad battery or the system has lost programming, refer to the owner's manual to change the battery in the remote and if that doesn't cure it the dealer must use a special tool to reprogram the system to the remote frequency. This solution is based on the fact that both the remotes don't work, the remote can be bad, this is esp true if it has been dropped.

Read this procedure to possibly fix the remote:

They also sell replacement remotes.

Normally, these remotes are programmable, I suspect that your remote lost it's programming maybe due to low battery condition. Look in your manual as how to reprogram your remote.

The flashing blue light shows that the TV is receiving I.R. from the remote but doesn't mean that the signal being received is recognized by the Samsung. If you have a "universal" remote then your TV code may need to be re-entered/reprogrammed...changing batteries in a "universal" will usually require it to be reprogrammed.

Also...because of the remotes construction (rubber membranes with carbon dots that short across PC traces) I've seen certain buttons stop working altogether.

If it is a universal remote not branded to the tv and the batteries went dead or are out for too long then the remote lost the codes and needs to be reprogramed!
