🔧 Card-Level Camera Repair Guide: If the screen remains pitch black but the status says "Active", ensure the hardware Privacy Shutter slider above the screen is completely open. For intermittent lines, screen flickering, or total component drop when moving the laptop lid, card-level troubleshooting dictates checking the Camera Flex Cable/Strip passing through the internal hinge module.

USB Ports & Audio Hardware Tester - Premium Diagnostics

🔌 USB Ports & Audio Jack Advanced Diagnostics Hub

1. USB Controller Scan

Mice, Pen Drives aur Controller lines ko thoroughly check karne ke liye Windows command use karein:

Get-PnpDevice -Class USB

💡 Execution Guide: Windows Search mein PowerShell khol kar is code ko paste karke Enter hit karein. Agar koi device list mein "Error" state show karti hai, toh drivers re-install karein.

2. Audio Channel Splitter (Strict Physical Isolation Mode)

⚠️ NOTE: Is mode mein hardware level par left aur right wires alag kiye gaye hain. Agar aapka right speaker dead hai, toh Right button par bilkul awaz nahi aani chahiye.

3. Speaker Sound & Frequency Oscillator

🛠️ Card-Level Port & Audio Tracing Rules: • USB Device Not Registering: Card-level par schematic diagram se USB controller chip ke paas check karein ki data lines (`D+ / D-`) short hain ya main `5V VBUS` power supply dead ho chuki hai.
• One-Side Audio Sound Cut: Agar left/right separate test karne par ek side bilkul mute rehta hai, toh Audio Jack ke andar ka metal pin spring physically bend/loose ho gaya hai. Motherboard trace mein main Audio Codec IC coupling capacitor leakage check karein.

Aap kisi bhi color block par click karke use manually check kar sakte hain, ya niche diye gaye green button se pure keyboard-controlled manual test shuru kar sakte hain.

Manual Color Blocks Selection

🔧 Card-Level Display Repair Rule: Full-screen mode controls enable clean panel overview tracking. If color spots or clouding lines fade away completely during dark screen cycles, the target defect is static panel stress.

💡 Keyboard Controls (Manual Mode): Test shuru hone ke baad agla color laane ke liye keyboard ka SPACEBAR dabayein, pichle color par wapas jaane ke liye Backspace dabayein, aur test se bahar aane ke liye ESC ya mouse click karein.
