Sounds like an AGC [Automatic Gain Control] problem with its video IF stage circuit. Contact any service technician, or service center. This is not a user repairable fault.

Sorry to inform you the audio carrier frequency in your country is different from the the other three countries you have mentioned. Don't loose heart you can always purchase a local Set Top Box and connect the AV out ( Yellow/ Red / White ) of the STB to your TV's AV in. There are no carrier frequency issue here. Or even better buy a Digital Set Top box and enjoy good sound and picture !!!

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...

Since retuning my Sagem DVR6200T/6400T settop box I have been unable to receive BBC channels. I am using the default code 0000. Can you please advise. W M Fitzgerald MK17 8DJ


When TV channels are moved from one frequency to another frequency that was previously used by a different channel (sorry, but there's no simple way of saying that !) as has happened recently in th UK, some digital TVs and digiboxes struggle to sort the channel list out properly and channels can go missing.

If your equipment has the option to delete all currently stored channels (normally in the tuning menu options) then do so and then do a full re-tune.
Sometimes, this solves the problem as the equipment is no longer aware of any previous use of a frequency and just loads every channel it finds.

If this doesnt work, or your equipment doesnt have the option, then there is normally the option soemwhere in the menus to retore the item to "factory defaults/configuration". This will clear all previously stored channels and after a full re-tune your missing chanels should be there. However, any other configuration changes you previously made, e.g picture size, output type (RGB/NSCT/etc), etc will be lost and you'll need to set these again.

NB. some regions of the country have lost some channels temporarily now until after the switch over programme completes at the end of 2012. If you visit the Freeview website, this will tell you if your area is affected.

How do you clear all channels so i can put the channels that i want in it


There is no need to clear the scanner before reprogramming. When you enter a new frequency it will automatically overwrite the old frequency. To clear unwanted frequencies you can program "0.0" into any channel to clear it, or simply use the LOCKOUT feature to prevent the scanner from stopping on a channel.

One channel fuzzy


Tis is an ongoing problem I seen increase alot over the past few months. From what I can gather, all the channels being broadcast over going from the analog to digital, there's no big suprise to anyone. However, the change from analog to digital is changing at a faster rate, so when you look at the TV some channels will be fine and others will have grey lines, fuzzy picture. The only solution-you need a TV with some kind of digital tuner. On the TV itself if the (TV has one) it will say "SD" or "ED" which stands for standard digital or enhanced digital.
