My Bush TV sends a message about changing channels every so often, even though nothing has been preset. How do I stop this?

I am unable to see at a glance how to correct this but it is between its menu, channel and volume buttons to alter the settings it may be worth to run through the re-tune sequence below?

Hope this helps.

Different digital boxes and tv's have different levels of RF gain. Some need more signal and some need less to work efficiently.
Possibly your Bush pvr needs a much stronger signal than your tv so the available signal is permanently on the threshold of reception and atmospheric conditions will some of the time reduce the available signal when reception will become impossible for the box but still be above the threshold for the tv set.

Modern Bush is not reknown for being a high quality brand and the purchasers of budget brand pvr's often discover reception or performance problems in fringe signal areas. Because a single aerial must receive a very wide range of frequencies it will be more efficient for some channels than others and so one channel could be a fringe channel and another channel produce a very strong frequency.

The signal strength and quality can be checked for each channel by selecting options in the menu in order to check this theory.

The problem might be solved by replacing the Bush pvr with a premium brand or replacing your aerial for a more efficient type. One of my friends had five different boxes before he gained a satisfactory performance and another friend three boxes and still has problems.
My installation has a new high gain wideband aerial on top of my 3 storey house and a distribution amplifier in the loft to keep the input lead short and the whole lot connected by very good quality double-wrapped co-ax.
I had to add different amounts of attenuation for each box or tv set but in spite of the signal being on average too strong and needing attenuating there are still channels for which the aerial is not as efficient and providing only a weak signal.

Check and replace its main system control memory IC. It is faulty.

REMOVE THE BATTERIES FROM YOUR REMOTE AND TRY USING THE CONTROLS ON THE TV

Check and replace the main system memory IC. It is faulty. It is a very small IC, won't cost more. An eight solder terminal IC. Even though the physical size is small, function to it when the TV works is great. The work is a skilled one.

On my Bush cdab51rr radio, the select button is marked ENTER. Hence:-
Choose the required station with Left/Right arrow buttons, press ENTER. Press and hold PRESET button until number flashes.Quickly scroll through preset channels with arrow buttons.When required preset chosen, press ENTER.

bush tv button wont work tv flashes when buttons are pushed but does nothing

Hi,
Though you have not mentioned model and brand of your tv so I can offer a tip only here.
Check in what order tv changes its channels, like if its in forward order, +Preset or +Channel knob would be stuck. If its changing in reverse order, check -Channel knob at front of tv.
Hope this info would be helpful.
Thank you.
