OK I understand that the backlight is working but I require even more clarification and troubleshooting.

Does the Beko display information display on the television screen? For example do you see the volume bar going from left to right and right to left on your screen when you press the volume key? Do you see the menu display when you press your menu or setup key?

Are you connected to cable or satellite? Do you have a cable box or satellite tv box?

Have you tried another device like a DVD player or bluray player.

Are you connecting with an hdmi cable?

We need a bit more information then we can proceed to better assist and discuss a possible repair strategy like loose inverters.

Hi


Thanks for using FixYa. To check what has gone bad you’ll have to open the back of the unit and check the backlight inverter board. The inverter is the power supply source for the backlights. If that’s the issue then it’s always better to replace the inverter board completely just to avoid any future issues. If not then check the power supply board however, it seems to be the inverter board as the sound is still working fine.Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks
Rylee

    Please check the below picture as inverter board looks like this, and is normally supplied by a dedicated voltage from the power supply (24vdc), check if the inverter board is getting that from the power supply:

My 32in beko tv keeps blinking and will not stop. The sound And picture is still good the screen Just goes black every other second Model nr 32WLZ530HID Service info Ix-Id tv...


It sounds like the backlight inverter circuit has developed a fault. This can usually be cured by changing some transistors and capacitors, or it could be a poor solder joint.
I hope I have been of help but please do not hesitate to ask if you have any further questions.
I appreciate your vote if you appreciate my reply.
