Hi - A'Cats,

Guess this might be a Beko with in-line PS. Check Wiltsgrove - pretty cheap these days - £8.95 + Vat.
All the best -   Chris.

Hi,

Yes, but -

You're now talking 24v - not usually the biz with small screen tellies. Now Wiltsgrove does the 24v version as well, pound or two more, but on a small screen - I doubt it , what's the invertor  ?  - Chris.

hi
turnip sorry typo error should say 12v on inverter with 3v on turn on connection both stay on when fault present but no power on lamps

sounds like the 12v is missing to the inverter.

Hi A/Cat,

As I have nothing on your actual model but guessed it might be like the DVD-less version that had a Beko mainboard, attach my file as this model had mainboard Buck convertor probs.

All the best - Chris.

Hi Cat,

Doesn't seem big enough for the more usual Darfon trannie probs we know so well - give a clue - Chris.
