Question about Symphonic ST419E TV

TV Will Not Turn Off With Digital Cable Control

I recently went digital with Comcast Cable. I followed the directions to set up the cable box and program the remote. The setup codes that Comcast gave me for Symphonic TV's are 10180 and 10171. When I programmed in 10180, the remote did not control the TV at all. When I programmed in 10171, something strange began. When I push the "All On" button on the cable remote to turn on the cable and the TV, both come on as expected. When I push "All On" (or use the "sleep" timer on the remote), power to the TV does not go off. The TV APPEARS to be off but there is still a faint light emanating from the screen and a buzz can be heard. If I push the power button on the TV or on the TV remote, the TV turns off. If I try to turn on the cable and the TV when the TV is in this "sleep" mode, the cable comes on and the TV turns off! So then I have to power up the TV separately.

I asked Comcast for help and they were NO help whatsoever. Can you advise me.

The remotes you get from the cable company are universal and kinda cheap. ive ran across this multiple times but since i dont know what model remote you have the only advice i can give is that the code you used is not the right code if it doesnt do all basic functions (on,off for the tv,volume)its just the wrong code if the codes you stated are the only ones available the book you got with the remote should explain how to run an auto scan.hope i was some help

If your using digital cable it will only record channel 3 or 4 depending on what your cable box is set to...In order for it to record different channels it needs a cable source plugged directly into it.

"auto-programming" may be limited even with a 2nd cable box. If your only using standard cable 1-125... you can use the TV/VCR button it will switch between the tuner of the TV & VCR allowing you to record while you watch a different show... keep in mind this won't work for digital channels which if I'm not mistaken comcast has already converted all channels to digital even basic.

I think I may have the "answer".

I am in Atlanta and have a Panasonic DVR that was working fine and sometime during the past month or so we lost the channel listings. I've tried many resets as well with negative results.

I called Comcast tonight. The agent helping me took a long time to research the issue and gave me this answer (which sounds reasonable). By the way, this is for the Atlanta area and may not be applicable to other areas of the country.

Due to delays in the conversion to broadcast digital and the fact that Comcast is experiencing bandwidth issues, they have digitized the "channel listing" signal. By mid-June Comcast's signal will be all digital and you won't be able to watch a TV connected directly to Comcast cable - regardless of whether it has digital or analog tuner (or both). This is contrary to what I'd heard before.

After mid-June, you'll either need to use a cable box OR what she called a "Digital Transmitter Adapter" (let's call it a DTA). Prior to being converted to "full" digital, you'll get notification from Comcast. She said I'd be able to get 2 DTAs at no charge (I currently have one Comcast HD DVR box). Additional DTAs would be $1.99 a month. DTAs will only provide access to the "basic" cable channels, but the good news is that the Panasonic DVR should be able to obtain its channel lineup through this DTA box.

If you have any questions, please feel free to contact me directly at

Good Luck!
