Facing TV Problems? Ask a TV Technician.
OK, can you please elaborate - " the cable remote will operate the DVR and TV except for the volume"?
- Does that remote power up and down TV?
OK, can you please check Samsung remote with cellphone camera to see if it is sending out infrared signals as shown in following image link..
OK, so TV remote itself is working.
Can you please check the IR board (where remote sensor/ receiver is mounted) is plugged securely to main board of TV?
TV has remote sensor on small circuit board (calls IR board) that would be located on lower front which receives remote control infrared signals and provide it to system control chip on main board of TV.
That IR board would be connected through harness to main board of TV, is that harness plugged securely on main board?
I guess I wasn't clear in above reply, I was talking about IR board inside TV as you said you recently replaced main board in TV so thought the IR board connection cable should be checked.
No problem, we can take it up by tomorrow.
