Your Tuner might be faulty but before replacing it there's also 1 thing to be checked.
You need to bring your unit to repair to checked the band switch I.C. before replacing the tuner.
Tuner is divided into 3 bands (VL,VH,UHF) since you have no reception on the lower channels, it seems that your VL bands is faulty that might be cause by defective tuner or Band switch I.C. located near your tuner.

The tv wont pick up cable channells 2-6 and i cant figure out why


From your description it sounds like the lower channels 2-6 are not working, this indicates a tuner problem in your tv, to fix this will be expensive. But if you have a vcr you could use it as the primary channel changer eliminating any costly expense.

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


Hi:
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.

Sanyo Model AVM 3659G won't recognize DVD player


Hi,

Let's try the easy one first:
  • verify the connections, normally yellow for video, white & red for audio. TV has to be set to Video 1, A/V or Channel 0;
  • in some instances, it could be a single coaxial cable. If it were so, the TV has to be set to Ch 3.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.
