[Lukasz Stanczak]

Hi everyone

was wondering if I could get help here please

My Beovision 7 40  7744 model stooped working.

So I’ve gone the research and found info on this forum and 3 things that could be wrong with it
PSU PCB
T-con PCB
And inverter PCB

or maybe someone here have other idea what can be wrong with it

But how do I know which part is broken ?

These parts are not cheap PSU PCB is like €500

Dont know if this is worth fixing
I don’t even know if it’s sellable broken like this.

Help please

Hi

Decided to try my luck and see what might be wrong with it myself.
So took the back cover off and one of the cables was loose so i pushed it back and guess what… it’s working fine. Very good news for me.

if anyone is reading this, don’t give up on your tv take the cover off and look for loose cables 🙂

Luckily for me it worked in my case

Good luck
