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...

Select TV as input source by TV remote or push Channel button on remote then go to TV Menu. That will enable Tuning menu in TV.

Cant retune my digtal freeview as my picture keeps freezing


The retuning process is as follows:

  1. Press the [i+] or MENU button on the remote control to display the DIGITAL INFO menu.
  2. Press the BLUE button to display the MAIN MENU.
  3. Press the UP or DOWN buttons to highlight AUTO TUNING then press the OK button to display the AUTO TUNING MENU.
  4. Press the RED button to start the auto tuning process for all available digital channels.
  5. Wait for the process to complete.

If you wish to CANCEL the auto tuning process whilst it is processing then press the BLUE button at any time.

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

http://www.freeview.co.uk/_retuneinfo/

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.

I have a mitsubishi tv that when it was unplugged will not


The set may have reset itself to "air" tuning model when it was plugged back in. Set it for cable tuning (may say "CATV") in the setup menu, rescan your channels and you should be good to go.

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?

Hitachi T.V. remote CLU3842WL will not change channels.


There are two possibilities: either the channel memory has been lost due to the TV being unplugged for an extended period or the digital tuning system has a defective component. First thing to do is go into the TVs menu system and try to re-scan the channels. You may find that you can change channels after doing this. If its still not changing channel, the digital tuning board will have to replaced.

Samsung tv problem


Hi.

You havent listed your TV model but most Samsung sets that are digital will have A button on the remote marked DTV this will tell set to look at the digital chans.
Now try & go in to the menu & select tuning & scan the digital chans in.
One other thing are you in an area of the UK that can pick up digital channels without changing your aerial.
