HDMI Tester TOPO — HDMI Port Tester for Console Repair

Designed and built by Torays Boost, a console repair shop in Miami, FL. We use it every day on our own bench.

Why repair shops use it

• Show your customer a quick test when the console arrives — they see which pin is bad on the spot.
• Replace the HDMI port and confirm everything is OK — all 19 LEDs green before the console goes back.
• No multimeter, no probing pin by pin.

What it does

Checks the 19 pins of a console HDMI port with the console off. Each line shows GREEN = OK or RED = check this line: open line (OL), short to ground, or a difference between the differential lines (D2±, D1±, D0±, CK± should measure the same; a difference often points to a bad HDMI chip / codec).

Tested on

PS5 (original & Slim) · PS4 · Xbox Series X.
Xbox Series S: not confirmed. Xbox One: not supported.

User guide

Before testing — IMPORTANT
With nothing connected to the tester's HDMI (not even a cable), connect USB-C and press TEST. All 19 LEDs must turn RED. This checks the LEDs and saves a clean reference, so the readings are accurate. Do it before every test. On PS4 it is required: without it, the PS4 differential lines can read wrong.

Testing a console

1. Console off and unplugged.
2. Plug the tester all the way into the console's HDMI port.
3. Connect USB-C power. PWR turns green.
4. Hold the tester firmly so it does not move. Press TEST (T). The light runs across the pins twice (~5 s). If it moves, a pin can lose contact and show red.
5. Read the result.

Reading the result

• All green: the port pins and their lines are OK.
• Red on a line: that line has an anomaly, is open (OL) or is shorted. Check that pin (connector, solder, trace, protection diode).
• All red: the lines may have an anomaly, be open (OL) or be shorted. Also check that the tester is fully inserted and the port ground is not broken.

Console profile (advanced, optional)

• The tester always starts in GENERIC mode (finds opens, shorts and differences between differential lines).
• Short press CAL (C): GENERIC → PS5 → PS4 → XB1 → XBS → GENERIC. The console LED shows the choice.
• Hold CAL 3 s with a known-good console of that model connected: 3 green blinks = saved. If red pins show for 5 s, nothing was saved (console not good: short, open or uneven differential lines, or bad contact).
• You can always save a reference again: the new one replaces the old one for that profile.
• After that, TEST in that profile compares against the good console. Only calibrate with a console you know is good.
• Factory reset: hold TEST + CAL while connecting USB-C (red and green blink 3 times). Then repeat "Before testing".

• 1 × HDMI Tester TOPO tester in protective case
• USB-C cable not included (any phone charger works)

A green result means the lines tested OK electrically. It does not test video output or the full operation of the HDMI chip.
