Dell Vostro Reg. model: P52F 2 Amber 7 white lights
My Laptop was working well until the screen froze for which I had to shut it down via the power button. Then when I tried to restart it, it gives me the 2 Amber 7 White error signal. I've researched for a fix and found out that the problem comes from my display screen, however I'm unable to find a solution. Due to the pandemic, I am unable to find a decent workshop to get my laptop fixed, any suggestions?

That suggests the display is faulty - next step is to replace it.

Start by seeing if the screen works. Hold the D key through powerup.
If you do see the screen self-test run, the screen itself is OK. In that case, you'll need to proceed to checking the cable that connects the display to the system board for damage or loose connections.
If the cable is damaged, it will need to be replaced.
If the cable is OK, and the screen works, it's the mainboard that's faulty.
If the display shows no self-test, the screen is bad.

The model I use doesn't have HDMI Cable.
