Standby light flashing, Brandt TV

Try disconnecting it from the power source for a while, for example in the evening, and plug it back in the next day; generally, the blinking power indicator means there’s a malfunction.

I tried, but nothing works..
It's strange because I can adjust the volume, access the menu, but I can't get a single channel..!

Hello
by reading your notice you will surely discover a line that explains that if the power light is blinking and the TV won't start, it's faulty; you tried turning it on and off, unplugging and replugging, doing wild reset attempts! that's not going to eliminate your malfunction for which your TV must take a mandatory trip to after-sales service. For your information, the age of a TV means nothing anymore, all electronic components have a limited lifespan. Some even fail during the warranty period, then it's just a scratch card game you win or lose but nothing lasts anymore sadly. As a bonus (let's get our tissues out) some manufacturers do not detail the components and offer "cards" or entire modules at high prices. So ask your after-sales service for a quote.
Hang in there

Thank you for your response.
I have already tried several times to unplug and then plug it back in a few hours later, but nothing works.
I can still access the TV menu, but I can't get any channels..

Here it is, but I don’t think it’s worth having it repaired, considering, as you said, the price of the parts and the labor is extremely high!! And it’s no longer under warranty.
Thank you for your response,
Best regards,

Hello
Maybe? To reassure you, consult a customer service that you trust. Not all of them are just card changers, and sometimes a small, inexpensive component can cause chaos. A repair estimate comes at a price too, and it’s often wasted money because they are high and discouraging. We have entered the era of disposables, in TVs as well.
