Just picked up a 42hm66 and no matter what i try it will only tune in a few sd digital channels on QAM but no hd. Now my 55 inch Mits crt with cable card will tune all the free hd locals over qam when i pull out the card or even on ant2 input no cblcard at all. So i know its not my wiring since i used the cable from the mits and ran it into the Tosh. It is puzzling to say the least and i was wondering any thing im missing. i even tried cable standard plus hrc and irc modes in the setup but no luck. Any ideas???? before i exchange it. :cool:

Can you receive the same SD digital channel for free on the Mits that you are receiving on the Toshiba?
If not are you sure that you are using the QAM tuner in the Toshiba and not the ATSC tuner or analog tuner?
Cable standard anad HRC modes are analog NTSC video not digital ATSC or QAM.

Are you sure your tv has a digital cable tuner like the mitsubishi? Are you able to tune digital sub-channels like 2-1, 4-1, 5-1, etc? Those sub-channels are often the HD version on cable.

I am getting some digital channels 110.07 is the nbc weather channel etc etc Its just the hd ones dont tune in. My mits picks up all the local hd channels no problem. If i punch in 101.704 on the Mits i get NBCHD i do the same on the Tosh I get a cute little box saying "no Picture"

When you select auto scan the tv does 1-125 analog first then does the digital next
it finds around 220 digital channels total which is same as the Mits but most are of course encrypted.

the Tosh has a TV/DTV button to go from analog to digital mode and i know its digital mode cause the sound level drops when in DTV mode

I metioned IRC and HRC since i have 4 options under input mode cable standard ,cable hrc, cabel irc ,and antenna when cable standard is picked it searches for the digital channels.

Hmmmm I'd just play with the setup and make sure you have all the basic settings correct.

It certainly sounds like you are using the ATSC tuner on the MITS.
The QAM channel frequencies on the Toshiba would not be at the same frequency as the OTA ATSC freqquencies since they are controlled by your Cable Co and not by the broadcaster and the cable company is probably allreadly using that frequency for one of its analog channels.

Im a bit confused since i dont have an regular antenna setup for the Mits how would it be using the atsc tuner if im pulling in NBCHD using just the cable hookup from the wall?

Tuners don't always number the same digital channel as the same number. It might be one number on one set and another number on another.
They also don't always list the channel as being available (encripted or not). I have three tuners and on one of them, a 'in the clear' channel isn't listed in the lineup.
I'm sure you are in the digital cable mode since you already mentioned a "110.07" channel number which is only a cable digital channel.

Frankly, I wouldn't doubt it that this was some kind of ploy to get you to rent their box though I'm sure they would deny it. :mad:

Cable STBs' are a 'cash cow'!

If it were a ploy by cablevision then why does my Mits tune them with no problem???

There appears to be something wrong with the Tosh QAM tunner since it apparently can find and play unenycryupted SD digital channels above channel 125 but can not find any of the unencrypted HD resolution digital channels above channel 125.
Do you know what range of channel numbers your cable vision service uses with its normal digitsal STB interface for the HD resolution channels? For example on my Cox digital service STB analog NBC is on channel 4 and digital NBC is on channel 704

Kinda funny you said that since cablevision is the same nbc sd 4 nbc hd 704 when using my dvr or cablecard

and when using the Mits tuner nbc hd is 101.704 Im starting to think its a problem with the tv itself since i get intermittent wavy lines on channel 2 sd and thats using the direct from street cable line.

Is input set to CABLE vs. ANTENNA? I don't see any HRC/IRC related settings in the manual.

My MX195 can tune to digital in-the-clear channels including HD without the cablecard.

All inputs are set properly and This model does not have a cablecard. Im hoping its the TV cause Im exchanging it Saturday and if the new one does the same thing then Toshiba needs a firmware update for sure.

If it were a ploy by cablevision then why does my Mits tune them with no problem??? Maybe because they can only screw with it so far without screwing up their own equipment (PSID data that is). One set is more forgiving than another to poor data. I don't see any HRC/IRC related settings in the manual. I don't know if that is a issue with QAM as it was with analog. Never came up before.

The hrc/irc is under the input type menu you have these choices antenna,cable standard,cable hrc,cable irc. When i auto scan the channels with hrc or irc i dont get the 250 digital channels found message i only get that when i set it to cable standard and it searches analog first and digital second.

Im convinced its the tv since im seeing wavy lines on analog channels and that happens at my house (all new wiring etc ) and my dads house which is a few blocks away and same cable company ( its his tv anyway ) so maybe i just got a bad tuner. and if the new tv does the same thing then i know its cablevisions fault ( probably ) or Toshiba needs to get a better QAM tuner.
