Sharp TV image issue.

Hello,
I own a Sharp Aquos LC 46HD1E television.
Recently, I have been experiencing difficulties obtaining a picture, especially for TV broadcasts.
When I turn it on, it shows a blue screen (no signal), which is normal.
When I start the TV decoder, the picture appears normal for a few seconds then gets scrambled (multicolored horizontal lines) before turning to a black screen a few seconds later. The sound reception remains normal.
I have to turn off and restart the TV and the decoder (Orange satellite) multiple times before I get a normal and stable picture.
Remarks:
1/ This malfunction is quite recent and I had no issues with the same equipment (TV and decoder) before.
2/In DVD playback mode, there are no problems with the picture or sound; everything works normally from the start.
I have been a bit long-winded, but thank you for letting me know how I could resolve this issue or guiding me on the type of malfunction it might be.
Best regards

Hello,
with this kind of problem, you need to diagnose to separate the issue
let me explain > either it's coming from the Sharp TV, or the TV decoder (given the symptom, I'd say the decoder)
So if you have another smaller TV, try it > if the problem continues, it's the Orange satellite decoder that is malfunctioning
Be careful! the decoder may work perfectly: it could be that the satellite signals are poor (dish orientation, satellite dish not aligned...)
- How is the TV connected to the decoder? what type of cable?
> if it's an HDMI cable, you can use a PC monitor/screen to diagnose as well

Thank you for the quick response.
I didn't reply immediately because the notification message was flagged as spam by my computer.
It's a satellite decoder, but the reception is excellent, and when there is bad weather, the picture on the screen changes (pixelation followed by absence of image with the message "network temporarily unavailable").
The connection between the TV and the decoder is HDMI. I just performed the test, and everything works perfectly right away and for a long time.
So it’s coming from the TV. I opened the back panel, removed all the dust, and checked the overall condition of the circuits and connections. A priori, there is no break in the soldering, no broken wires, no circuits that seem to have overheated, and the fan is working normally.
So I am completely lost in identifying the problem...
I would therefore appreciate any suggestions that could help me resolve this at minimal cost.
Best regards.
