The 5V line is mainly used for HDMI display detection. Make sure **JP1 is not shorted during normal use**. \u003cbr\u003e\u003cbr\u003e**LED Stays Solid** – The **CLK signal is missing or shorted to ground**. Check and reflow the CLK connection.\u003cbr\u003e\u003cbr\u003e**LED Blinks but No Picture** – The FPGA is receiving the clock. Check all **VData\/VD# and CSEL connections**, then test another HDMI cable and display. \u003cbr\u003e\u003cbr\u003e**No HDMI Signal but Analog Video Works** – Reseat the **FFC cable** in the correct orientation and inspect both ZIF connectors. Check the HDMI PCB, cable and display. Do not pinch or sharply bend the FFC cable. \u003cbr\u003e\u003cbr\u003e**Intermittent \/ Corrupted \/ Garbled Video** – Recheck the QSB for cold joints, bridges or weak connections, especially the digital video lines. GCVideo Diagnostics can identify VData lines that are missing, stuck, swapped or shorted.\u003cbr\u003e\u003cbr\u003e**No HDMI Audio** – Set **Enhanced DVI Mode = On**, check **Volume** and **Mute**, then verify the **LRCK, ADAT and BCLK** connections.\u003cbr\u003e\u003cbr\u003e**Crackling \/ Distorted Audio** – Check **LRCK \/ ADAT \/ BCLK** first. If **Sample Rate Hack** is enabled, turn it off and test again; this option can introduce slight audio artifacts. \u003cbr\u003e\u003cbr\u003e**OSD Menu Does Not Open** – Use a controller in **Port 1** and hold **L + R + X + Y** for about one second. If it still does not work, check the **PAD\/controller-data wire**.\u003cbr\u003e\u003cbr\u003e**Settings Are Lost After Power-Off** – After changing settings, select **Store Settings** in the main menu. Simply changing a value does not save it permanently.\u003cbr\u003e\u003cbr\u003e**Settings Suddenly Reset \/ OSD Opens by Itself** – Some **8BitDo GameCube Retro Receivers** have been reported to trigger the GCVideo reset combination. Remove the receiver and test with a standard wired controller.\u003cbr\u003e\u003cbr\u003e**TV Shows “No Signal” in 240p \/ 480i** – Some displays do not accept these digital timings. Try the **Line Doubler** to output 480p\/576p, or test another TV\/monitor.\u003cbr\u003e\u003cbr\u003e**Picture Disappears When Switching 480i ↔ 480p** – Some TVs\/scalers need time to re-sync when the video mode changes. Try switching HDMI inputs and back, enabling the Line Doubler for the problematic mode, or testing another display.\u003cbr\u003e\u003cbr\u003e**Brief Black Screen During Game Transitions** – Some games change video timing between gameplay, menus or cutscenes. A short HDMI re-sync can occur and does not necessarily indicate a faulty GCDual. GCVideo 3.1 reduced excessive blanking in some games.\u003cbr\u003e\u003cbr\u003e**Washed-Out Blacks \/ Crushed Blacks** – Match the GCVideo **RGB Full \/ Limited Range** setting with your TV or scaler. A range mismatch causes washed-out or clipped blacks and whites.\u003cbr\u003e\u003cbr\u003e**Wrong Colors After Changing Digital Color Format** – Some displays do not correctly support **YC444 or YC422** in every mode. Return to a compatible RGB output setting and test again. YCbCr settings may also affect the auxiliary analog output.\u003cbr\u003e\u003cbr\u003e**No RGB \/ YPbPr Analog Output** – Check **Analog Output** in the GCVideo menu and verify the QSB jumper configuration. Grounding the **Mode (M)** input forces YPbPr.\u003cbr\u003e\u003cbr\u003e* **RGB \/ Sync Problems with SCART** – For **GCDual 5.3 and later**, JP2 must match the SCART cable configuration. Follow the 5.3+ installation guide rather than older 5.2 instructions. \u003cbr\u003e\u003cbr\u003e**Using Luma \/ Chroma \/ Composite Pins on NTSC Consoles** – The original console signals must be disconnected before GCDual reuses these Multi-Out pins.\u003cbr\u003e\u003cbr\u003e**RGB Problems on PAL Consoles** – PAL consoles already have factory RGB signals on the Multi-Out. The original RGB\/S signals must be disconnected as specified in the jumper guide before GCDual drives those pins.\u003cbr\u003e\u003cbr\u003e* **RGB Pads Appear Shorted to Ground** – Do not immediately assume a fault. The RGB outputs use **75Ω termination**, so a low-resistance path to ground can be normal. Check actual resistance and the schematic before removing parts. \u003cbr\u003e\u003cbr\u003e**480i Line-Doubled Picture Looks Unstable or Poor** – This is a limitation of simple line doubling. If your display accepts 480i\/576i directly, GCVideo recommends disabling the Line Doubler for better image quality.\u003cbr\u003e\u003cbr\u003e**PAL Game Does Not Offer 480p** – This is usually not a GCDual fault. Most PAL GameCube games do not provide a native progressive-scan option. Swiss can force progressive output for some titles.\u003cbr\u003e\u003cbr\u003e**Black-and-White Picture with No Audio** – GCVideo may be running in **Firmware Update Mode**. In this mode, black-and-white video and no audio are normal. Exit the updater or complete the correct firmware update.\u003cbr\u003e\u003cbr\u003e**Older Firmware \/ Compatibility Problems** – Check the version in the GCVideo OSD. **GCVideo-DVI 3.1** remains the official latest release and includes improved audio timing and compatibility with some displays. Use the **dual-gc** firmware for GCDual hardware. \u003cbr\u003e\u003cbr\u003e**Most GCDual problems are installation-related. If a problem occurs, first check the QSB solder joints, CLK\/VData\/audio connections, FFC cable orientation and GCVideo settings before assuming the board is defective.\u003c\/p\u003e\n\u003cdiv\u003e\u003cimg class=\"detail-desc-decorate-image\" slate-data-type=\"image\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S50e864496d8440ef9f952713ffa90b5cg.jpg\" style=\"margin-bottom:10px\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"CRTWAVE","offers":[{"title":"GCDual 5.3.1","offer_id":67830544662605,"sku":"1005013173939395-GCDual 5.3.1","price":161.39,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0793\/9909\/2301\/files\/S50e864496d8440ef9f952713ffa90b5cg.webp?v=1793179076","url":"https:\/\/crtwave.com\/products\/gcdual-5-3-1-hdmi-video-mod-kit-for-gamecube-dol-001-gcvideo-digital-audio-rgbs-rgbhv-rgsb-ypbpr-output-professional-install","provider":"CRTWAVE","version":"1.0","type":"link"}
