My TV model tx-l22d28bp, is pixelating on all channels no matter

This answer was rated:

My TV model tx-l22d28bp, is pixelating on all channels no matter what the signal strength. Tried another tv on the same aerial cable and it worked fine.
I just need to ask for more info please. if you use another input like a DVD player for example is it OK using this?

I have not got a DVD player I can easily try on this TV, if I had I would probably use an HDMI connection rather than an aerial lead.

I have to go out now, will reply to any queries when I return.
No that is not an answer it was just a request to see how the set behaves without using the tuner however>>
OK its likely to be a bad tuner within the set mounted on the main-board now your best workaround option is to get a set-top-box and use that rather than replace the main-board which may not be available anyhow and be a much cheaper option, if you wish to replace the main-board you will need to get the part-number found on the main-board itself on a sticky label or etched on the board, the main-board is the one with all the AV connectors on google the part-number for suppliers.
Let me know if you need more info

I have now discovered that it could be 4G interference affecting the older TV more than others. I am better off researching things myself than paying for it.
Its possible the thing is you would need to buy a filter anyhow the best workaround is the set-top-box because you then have newer technology tuner in a 5 or 6 year old set and in any case with band compression going on every couple of months that tuner in the set soon may not even work.
