Find the HDMI fault in seconds.
A custom-built tester and desktop app that reads all 19 pins of an HDMI port, pinpoints shorts, opens and bridged data pairs, and tells you whether the console's HDMI is really the problem — before you touch the soldering iron.

Stop guessing. Know the port is the problem.
Probing 19 HDMI pins by hand with a multimeter is slow and easy to get wrong. This kit reads every pin for you, flags the exact faults, and shows the customer real proof — so you quote with confidence and only reflow when it's actually needed.
Diagnose in seconds
A full 19-pin scan runs automatically and updates live — no more probing one pin at a time and losing your place.
Pinpoint the real fault
Instantly flags shorts to ground, open/broken pins and bridged data pairs — the failures that actually kill an HDMI port.
Quote with proof
Export a clean CSV report and show the customer the evidence. Fewer "do I really need this?" conversations.
A diagnostic dashboard, not a wall of numbers.
The included Windows desktop app turns raw pin voltages into a clear verdict: a live connector map, per-pin readings, and a plain-English fault analysis.

Diode-mode scan showing all measured pins nominal, with an 18 / 18 OK result.

Pin 1 is flagged in red as SHORT, with a fault explanation and a 17 / 18 OK result.

Multiple pins are flagged in orange as OPEN, with a 9 / 18 OK result and connection details.
Built for console & board-level repair.
One tool for the HDMI faults you actually see on the bench — from PS5 and Xbox to laptops, monitors and TVs.
- All 19 HDMI Type-A pins read and mapped on a visual connector.
- Two test modes — diode mode (console off) and live voltage mode (console on).
- Automatic fault analysis — shorts, opens, bridged pairs, missing +5V / HPD.
- Console power detection — tells you if the port is live before you probe.
- CSV export for records, quotes and customer proof.
- Demo mode to learn the workflow with no board connected.
- Windows 10/11 (64-bit) app — extract the full ZIP and launch HDMI Diagnostic PRO.vbs. The runtime is included.


Bluetooth built in. Mobile app on the way.
Every board ships Bluetooth LE enabled from day one. Today you run it over USB with the desktop app — and the moment the companion mobile app launches, you just install it and connect. No new hardware, no re-flashing.
Go fully cordless on the bench by powering the board from any USB power bank while it streams readings to your phone.
A real custom board — not a breakout hack.
Purpose-designed around an ESP32-S3 with dual 16-channel analog multiplexers, so all 19 pins are sampled cleanly through one HDMI connector and read over USB-C.
Powered over USB-C — use a PC, a 5V wall charger, or a USB power bank for wireless use. No battery required.
Everything you need to start diagnosing.
