poor colour display on beko nr 28426nds

[tweddlea]

Hello everyone,

I am new to this forum.

i have a beko nr 28426nds for the last two years or so.

Recently the tv has had poor colour. for exapmle, people wearing red lipstick looks purple on the screen.

After a certain period of time which can be from approximately 30 mins to a few hours the colour will suddenly come back on.

Although, after turning the tv off and back on the colour is gone again.

Can annybody tell me what the problem might be?

is the tv faulty?

Would appreciate any help.
