[SOLVED] No signal with HDMI ?

[bozo98]

Hello.

I use a TV as a monitor, connected to my Radeon 6700 XT graphics card with HDMI cable and everything worked fine.

Yesterday i cleaned my PC. and now when my PC boots, the TV says "No Signal".
But when I unplug the HDMI cable from the GPU and plug it back in, everything works fine.
Why does that happen now?

Given how a traditional case/build will have all cables exiting the rear of the case(except the front panel ports), we're going to need to know what you're referring to as the back of the case.

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

If you're able to get display output to your Tv using the iGPU, then it's likely your PSU might be incapable of powering your system with the discrete GPU or that the GPU might've conked out. You could try and use DDU to remove all GPU drivers from your system in Safe Mode and then manually install the latest driver sourced from AMD's support site in an elevated command(assuming you're on Windows OS). If the PSU is at fault, you'll need to source(borrow, not buy) a reliably built PSU with the same of not more wattage at your entire system's disposal.
