So I have a 2009 Mac Pro which seems to boot just fine but I have no display out at all.
So I am wondering if there is any program or image I can use without screen to update the 4.1 firmware as I read about it
that can solve the issue. I would use apple 4.1 official just to overwrite the faulty firmware. With the holing of the power button I would be able to initiate an USB firmware update maybe?
Please advise

What makes you think flashing the firmware would solve a display problem?

What model of video card is in the machine? If it's not one made specifically for the Mac Pro or one that specifically has built-in drivers then you would not get any image on it at all.

A firmware flash would not do anything to resolve this. You should troubleshoot the video issue before even thinking about a firmware upgrade.

gt120, i did check the diagnostic lights and all the parts in an other mac pro.
all confirmed working and all original apple.
if you check apple reset smc description it says the firmware can cause no display and also i know apple has a program which can reflash a faulty firmware without screen attached.
just cant find it...
should be similar to pc bios flash usbs

Are you talking about the firmware restoration CD? You can download it and try it but I believe it only helps when the firmware is totally corrupted (in which case the Mac Pro wouldn't boot). If yours is booting up then I don't think your bootrom is the problem.

If you haven't already, try the GT120 in each of the four PCIe slots. Also, have you tried a PRAM reset?

Do you have another GPU you can try? Have you tried the both the mDP and DVI output on the GT120?

And are you sure the monitor is working? Cords are all plugged in? Cables are all good? I have been amazed over the years what can instantly go bad.

Did you tried to install 10.11 (most recent that works on a 2009) on a empty disk using another Mac, enabling screen sharing, then installing the HDD on your 4.1 and checking if the Mac works?

yes, I do this for years:) that was the first thing.
I mean I did have a clean install of Mavericks popped into the dead mac pro, but nothing.
What do you mean by screen sharing in this situation?
[doublepost=1539422014][/doublepost]did some extended testing, the diagnostic leds see on the picture.
I changed all the parts from a working 4.1 still 0 success.
Tried the restoration dvd but when I hold the power button and it starts blinking it does not give the beeeeeep nor open the tray.
If i open it myself or insert the DVD before does not work either.
Tried all the PCI-E slots with a confirmed working Graphics card, 2 of them both Apple riginal GT120 and 5770.
Running out of ideas:)
The CPU tray works 100% also with original CPUS.
I tried a working DVD rom from an other mac which I used to burn the restoration DVD.

Any suggestion?

If you tested all parts, your backplane is the problem. Probably your BootROM is corrupted or you have a hardware problem. The next step is desoldering the SPI flash memory, reprogram it with a external programmer and soldering again.

I see, thanks. I just sell the case and PSU and other parts and buy an other Mac Pro out of that:)
In the UK parts goes crazy including the backplane... if you can find one, from the US they charge import fee so...

You don't have a friend that can solder and desolder the SPI flash for you? It's a 8-pin SOIC chip, easy to desolder and easy to program. With $20 you can buy a ch341a plus a SOIC-8 clip to reprogram the SPI flash.

is there any pictured tutorial for that? I might buy a soldering kit myself and that chip
