Television will not go above channel 47 or below 95

Okay my roommate has an older tv (Sanyo DS19130 manufactured 1992) and it does the weirdest thing. If your on channel 47 and try to go up one it jumps all the way to 95. If you manually put in channel 48 it goes to 47 if you manually put in 94 it jumps to 47. if you switch from cable tv to normal it lets you go to any channel however if you switch back to cable while on a channel 48-94 it again automatically jumps to 47. Now I know Occam's razor says that I'm just stupid and haven't added the channels or allowed the tv to scan for clear channels. However let me assure you I have tried that at least 10 times. I have a bit of a need to fix things and it's driving me insane. So any help or ideas would be greatly appreciated I'd be glad to troubleshoot with anybody. Thanks email me at with any ideas appreciate it.

    My 1991 Sanyo AVM250 has exactly the same problem.

    The only way I know of easily getting around this is to use a cable box to do all the channel tuning and feed your TV on fixed channels 3 or 4.

    If I find a tuner modification to fix the problem internally I'll try that and post the results here.

    I have the same problem with the same TV, I have searched all over the internet for any ideas and have found nothing. My next idea is to find a "master rest button\switch on it or internally. I would recommend that anyone that has this problem join me in my search and email myself or the opening poster with your possibilities.

I have a really old sanyo tv. The roommate brought it with a universal remote, which will not work with the TV, and I also bought another universal remote that will not work either. I just want to get to...

Sanyo sets, especially the old ones are like this, if no button on set the only thing you might try is run one channel at a time below channel 2 to see if one of the upper channels is the video input, other than that you are done.

My sanyo ds19130 television has black lines and video errors.

Nothing to do with the smoking, the problem is in the vertical deflection unit - the power circuit has a loose contact. Open the tv and check all contacts (including the ones to the coils) and fix them.

I have a sanyo tv. Slightly older. Not hi-def or New

This may be due to the possiblity that the you are on the wrong input source, If you watch HD Channels then the input source would either be componet or HDMI input. Try changing the input source of the television with the TV's remote until you see the Channels again. IF you are not watching HDTV then the television is on the wrong reception channel for the Direct TV's box. Try channel 4 or 3 or even 73.

How do you retune Freeview channel 5 for a Sanyo Digitital TV

You may lose some channels when you retune the TV as the channels have been rearranged. To locate them look at the EPG although you may still find that some channels are no longer available on FREEVIEW. See the following link for additional information

If the above process does not work then check the link above for additional information and also visit the accompanying site links below to find more information for your model of TV / FREEVIEW box.

Converter boxs

If you have cable or satelite service, no converter is needed for either one. The only time a converter is required is if you receive the TV signal from an antenna (over-air). The DS19130 WILL require a converter for over-air broadcasts. I think that the DS25530 will as well, but I am not 100% sure. Because of its age, I would suspect that a converter will be required for hte DS25530.

There is a button under the bottom edge of the screen (with the controls) that has the options "Normal" and "CATV" - press this and it should solve your problem.

No channels above 47

That works great except I can get the tuner to program any channels above channel47. Is this a limitation of this older model TV yes there is limitation in old tv. is there some setting I can change in order to get more channels using the tv tuner? in INDIA what we do is put a remote control ckt which gives us about 250 channels. of course we replace tuner also called hyper tuner along with remote ckt or replace whole kit which are cheaply available.& serves the purpose. hope this will help
