People are really going to kick themselves if they read this and have already thrown the tv away!! Try this fix, I had exactly the same problem as everyone else but every tv I swapped it with did the same thing so then I thought, I wonder if there is a remote somewhere being pressed down underneath something? So I covered up the sensor with a piece of blutack and boom the problem stopped and my tv started working perfectly ?? although I still haven’t found the remote in question but hey my tv works
This was requested on FIXYA many years ago without success.
I used https://www.google.com and did not see a manual, even on the United Kingdom Celsus web site. A free manual online for a different tv shows a web page and a customer support phone number to call. (I am not typing in the phone number her because there are so many fraudulent phone numbers posted on FIXYA, so beware.)

Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Celcus/support.php has codes in FAQ for TiVo and sky remotes, but not BTYouview. Advice from other post which worked for me was to use the code 4483 for BTYouview remote with Celcus. Hope this helps
Is there an online PDF of the user manual?
Currently user manuals are not available online, this is something we are looking to include in the future.
