Grundig TV no picture but intermittent sound

Hello,
I have a Grundig TV that I've had for quite a while. When I turn it on, I have sound but no picture. So I turn it off and on several times, and eventually it works correctly with a good image and perfect sound.
I've already done several power resets, but nothing changes.
I have a decoder and I changed the HDMI cable thinking that the problem might come from that, but no.
I tried starting it with nothing connected to it, and I still get a black screen.
It takes me about 10 minutes to get an image.
Do you know what this could be due to?

Thank you for your reply.

Configuration: Android / Chrome 78.0.3904.108

It's mostly when it's cold that I want to turn on my TV in the morning or at the end of the day. I admit I have never tried turning it off after a long period of use and turning it back on right away.
As for disassembling it, I'm not very handy. So that will be complicated.
In your opinion, could this be a problem that could cost me a lot? If a technician takes care of it. I know you can't tell me exactly what it is from a distance.

- Here, I am relying only on visuals.

- The cost: it will depend on the repairman you deal with. Some only work on these TVs, but the faults are not easy to detect. It could be a faulty component or just a simple soldering job, but you still need to know where.

- Asking for a quote is doable ;-)

"I admit that I have never tried turning it off after a long period of use and then turning it back on right away."

Try it and see.
