TelaKeppi Posted September 14, 2023 Report Share Posted September 14, 2023 I've upgraded my old XBlast + XboxHDMI setup to Stellar XboxHD+ kit and after powering on the system I have no video output. There's a green LED in the XboxHD+ PCB but it's not lit. I've measured the 5V pad and I'm getting around 4.91V. I've also replaced the QSB with a newer revision and it's measuring around 130 Ohms. Stellar board have been updated to the latest firmware before installing and the link cable is connected. Anything I'm missing or should I RMA it?

TelaKeppi Posted September 15, 2023 Author Report Share Posted September 15, 2023 The previous kit was installed by a repair shop, flex cable and all. So I've only replaced the QSB to a newer revision, attached old wires to new HDMI module, connected d0 to ground and removed old wires not needed any more. Can someone confirm the LED should light up as soon as you hit power button? Quote Link to comment Share on other sites More sharing options...
ghost2916 Posted September 20, 2023 Report Share Posted September 20, 2023 Same problem here. No power LED on the board. I'm using one with Openxenium. Kit arrived a couple days ago. Quote Link to comment Share on other sites More sharing options...

Ernegien Posted September 20, 2023 Report Share Posted September 20, 2023 Sounds like an install issue. I'd do a good sweep of the board for stray solder (or conductive pieces) and make sure there aren't any unwanted bridges. I've highlighted one area of interest. It's possible you've already damaged something if any of the bridges (now or previous) dealt with a power rail. Quote Link to comment Share on other sites More sharing options...

Definitely see what that is and check your connections, if you haven't already. Quote Link to comment Share on other sites More sharing options...

Checked for continuity between the legs and there seems to be none. Phew! Removed the speck but the issue remains, I think I'll have to revert back to the old HDMI mod to rule out issues with the Stellar kit. Thing is, I've already shortened and connected d0 to ground. Which I believe enables bios lookup from LPC port but does not enable the mod chip. My previous chip was Aladdin Xblast that doesn't have BT pad. Is there another way to enable it?

Ernegien Posted September 21, 2023 Report Share Posted September 21, 2023 What about this? It would be nice to see more photos of the install, particularly the flex portion around the encoder, because if I'm picking out multiple stray seemingly-conductive stuff floating around in a high-level blurry photo, there's likely others elsewhere There's still a real possibility something has been damaged in this process however. You can leave d0 shorted to ground and it will always boot from LPC, provided you have a functional modchip present. Quote Link to comment Share on other sites More sharing options...

I think that you can just wire a switch between the D0 and the ground if you ever need to disable the chip. 1 Quote Link to comment Share on other sites More sharing options...

TelaKeppi Posted September 22, 2023 Author Report Share Posted September 22, 2023 Reverted back to the old XBlast and XboxHDMI. HDMI board is blinking blue LED but no green so no picture. I've definitely damaged the flex install even though I didn't touch it much, only swapped the board and reattached the flex. The console does boot with the old XBlast, luckily I've set XBlast OS as a secondary BIOS, makes debugging so much easier. I have no proper equipment to reflow the flex so I'll contact the repair shop where it was originally installed. Also checked all the ram chips, there was a blob of solder in the other chip as well. I removed that but it looked like that may have been there since the ram upgrade. Quote Link to comment Share on other sites More sharing options...

At least with the XboxHDMI you could use it with any chip, although only a couple bioses. Quote Link to comment Share on other sites More sharing options...

Unless the BIOS patches are integrated in something decent like Cerbios, there's only bad and worse alternatives for my use case. Quote Link to comment Share on other sites More sharing options...

Right... the only reason 3rd party bios support was added was so that it could be used alone, since the Stellar didn't exist yet and MakeMHZ had to be forced to allow it to work with regular chips. That's why they supported bioses that nobody wanted to really use. They would never have supported Cerbios. Once the Stellar was funded and released, they went ahead and immediately moved a vital part of the HD+ over to the chip so that it now cannot function without it... for no reason other than they could. What is bad and worse, to you? Also, is there any reason why the XboxHDMI would NOT have worked with Stellar? Quote Link to comment Share on other sites More sharing options...
TelaKeppi Posted September 22, 2023 Author Report Share Posted September 22, 2023 I'm not following your logic, but there is currently no true HDMI product available that isn't tied to a software. Before the XboxHDMI I used X2 4981. With specific bios patches required that's not possible. iND is messing with my partitions = Bad, M8 doesn't support 128Mb = Worse. I'm fine with a product that ties hardware and software in single package if it has all the features I need. Like now with the latest firmware 128Mb support, 1.4GHz support and working partition utility, everything I need should be covered. And the Stellar upgrade kits were sold out so I opted for a full set. I figured I'll use the original in some of my other Xboxes. Quote Link to comment Share on other sites More sharing options...
