Model 50HM66. Why is there no sound on channels 6 & 32-1?


Could be a tuning problem but I have observed the same problem in this area, especially on channels with dubbed language translation. You can try repeating channel search to see if it helps.

I have timewarner basic cable and would like to view the hd channels such as 5.1 or 5-1. how to I get there, the remote has no . or -?


go to the options with the remote on your tv, then do a channel scan. it will scan for any channels you are picking up. if you have basic cable you will only have a few HD channels. if you have a cable box then the cable box should show you what channels are HD

Picture goes in and out


Hello,
This will require you opening the back cover of the television to test some component with the use of an ohmmeter.
This may be a slight drift - like someone is messing with the fine tuning
or such a substantial change in tuning frequency that the channels go by
as though you are surfing.

Possible causes depend on tuner type:

1. Quartz tuner (10 button direct access digital synthesizer) - For a
slight drift, a component is probably changing value, possibly the
crystal in the reference oscillator. For gross changes - flipping
through channels - it is more likely to be a digital control problem -
the microcontroller is misdirecting the synthesizer to change frequency.

2. Varactor tuner (buttons but not direct channel access) - If only a
single pushbutton selection is the problem, the the varactor tuning diode
for that button is probably changing capacitance. If all channels in
a band (Vl, Vh, U) are having a problem, it is more likely to be a
drifting D/A or faulty AFT (Automatic Fine Tuning) circuit or power supply.

3. Turret or switch tuner (Knobs) - A component like a capacitor is changing
value.

You will have to get in there with a heat gun or cold spray and track it down
the old fashioned way. At least, the problem is almost certainly localized
to the tuner box (and possibly the controller if applicable).

As noted, gradual slight changes in tuning are likely due to frequency
determining components drifting.

Uncontrolled channel surfing is probably a logic problem. For the
quartz tuner, this could still be marginal connections causing the
microprocessor to misdirect the synthesizer to change channels.

For the latter case, particularly, the cause may still be bad connections
resulting in loss of channel memory and/or erratic behavior.
Take care...

Programming Channels


Your TV is likely set for "AIR" tuning rather than "CABLE" mode. In this case channels above 13 don't tune correctly. The tuning mode is adjusted through the setup menu (it's been too long since I've seen one of these to remember exactly how the menu looks). Once you set the tuning mode for cable, all the available channels should come in properly.

But you've said you have satellite, so you should have a satellite receiver connected to your TV, and you'd be changing channels there rather than on the TV. Your TV would be staying on channel 3 or 4 (if using the satellite antenna output connection), or on the A/V input you have the satellite connected to (if using the direct A/V outputs). Am I missing something about your system?

no problem occur on your set but the only problem is you can not lock the fine tuning (in manual procedure) but is it better to set the program to AUTOSCAN OR AUTO PROGRAM and authomatically tune and save to the memory all the program channel
