My rmt-d248p remote control doesnt work my dvd recorder anymore. The tv functions on the remote still work i.e. i can change the tv channels, volume and turn the tv on/off but any of the dvd recorder functions will not work, it was fine last sat when i last recorded a programme but on fri i tried to turn the recorder on and nothing happened. Nothing has changed in the set up of the front room and the recorder hasnt been moved. For the life of me i cannot understand how the remote still operates the tv but not the recorder. The recorder still works fine if u use the buttons on the front of it to record but i cant access any of the menu's or programme lists because there is no button for this. Thanks in advance

It can't be done. The Sanyo remote is for a standalone VCR - DVD recorder. It has no programming capabilities.

if you have menu button on front of tv use up and down volume to autoprogram the channels

First hit the TV button again and try and change volume, if that doesnt work try a different code as many codes can do some functions and not otheres.

Try to clean contact with contact cleaner spray( radio schack or computer sotre.

If the problem persist Reset with you code in your manual if you do not have the code go to: esupport.sony.com and download free.

After that if the probllem remain, your contact in the remote control is faulty.
Replace it.
Good luck, G-d bless you

Some info (like how to re-programme for a tv) included in the HD/DVD recorder instructions:
http://pdf.crse.com/manuals/3113760121.pdf

Here you go. This will work with most all universal remote controls. If you don't have the code do the following:
Automatic Programming
With automatic programming, the remote control tests all the codes available on the Code List and assigns the correct code for the selected device. Although this method can be more time-consuming, it eliminates the need to look up codes and enter them manually.

1. Turn off the device with which you want to use the remote control.

2. Press and hold the corresponding button on the remote control
(TV, VCR, SAT, DVD, CAB or AUD) until POWER INDICATOR illuminates. It should take a couple of seconds for the light to remain solid. The remote control is in programming mode.

3. Press and release power button. The POWER INDICATOR flashes once and stays on indicating the unit is in Power Scan mode.

4. Press CHANNEL up or CHANNEL down repeatedly until the device turns on.

5. When the device turns on, press OK to store the code.

Note:
• To exit without storing the code, press BACK.
• T he unit will search for the next code or the previous code if you press
CHANNEL up or CHANNEL down after the device turns on. (go slow you need to press OK when the TV turns on) if you mess up turn TV off and start over.
6. Press any other button. If the device responds, the remote control has been programmed. If the device does not respond, repeat steps 2-5.

Fill free to ask me questions about anything..........................

1) replace batteries by new ones, clean contact from oxide, and see if the wires is open or brokern and repair

2) chek if the codes is o.k

3) was working before?
4) did rmote control was slip to the floor?
5) go to esupport.sony.com and download the code for Free and test the remote again.

Otherwise the remote is faulty. I f the TV is turn on, and changing channels.

sincerely. G-d bless you.

The Sony RMT-833 remote is for a Sony Camcorder - see http://www.replacementremotes.com/store/images/RMT833.jpg

I think you mean the RM 833 remote - if so try eBay as listings there suggest it works with Number: RM-833 Compatible with TV Models: KVX250, KVX2501D
Hope this helps

According to my manual the codes for Samsung TVs are 31, 32 or 43.

Press and hold the TV on and off switch button.
Enter the two-digit code for your television set (while holding the TV power on the remote)
