The problem you have mentioned indicates a backlight inverter board failure. Not a very difficult problem to fix and not expensive either. You can get a replacement board for about 30-50$. Only problem is finding the replacement. If you can get me the part number we can solve that too.

Do you see any capacitors that are swollen,vented or puffed up on Top ? If you do they are bad. 1000uf 16v, 220uf 10v, 3300uf 10v
Also Look for poor solder connection.For Parts/supplies Go to Encompass Parts Distribution and type in your Model number.

Hi


Thanks for using FixYa. From what you have described it seems that you might have a backlight and/or an inverter board issue with this TV set. It could also be due to the inverter circuits for the backlights. The inverter is the power supply source for the backlights. There could also be a screen driver problem; if it is then you have to change the entire inverter board. All this is only recommended if you have some kind of expertise for checking the internal circuitry of the TV as these units have high voltages running even when the set is switched off. The cost to change the inverter board including labor would be around $250, if you get this done by a professional. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks
Rylee

The LED back lights will not stay on. I have sound and I can see an image with a flashlight.


inverter board is most likely the culprit since it feeds power to the backlights.

Washing machine fills with water but then won't wash, spin or drain


Hi Claire if your beko washing machine wont drain or has a spin problem then you have to check the carbon brushes first.

Also check all waste pipes are clear and inspect the pump I have included this video below.

At our website I am doing self diagnostic videos on these beko's as we speak so all tutorials will be in this link below

you might find this test video helpful but only do it if you have checked the motor

When i turn on my tv the picture is fine then it goes darker and it stays darker


First things is check the picture adjustment.Try to adjust the brightness and contrast.If did not work the problem is the backlights of the LCD. Usually in that case the problem is loose connection in the backlights connector. The backlights have high voltage so it may cause of overheat at the connector.So try to check the connection of the backlights at the board of your television.Remove the back cover of the TV and look the conector of the backlights and try to resolder and fix it. Thanks!!!!
