Black screen after I tried to flash my HD 6850

[Lord_SharK]

hello brothers. I have a problem that I need help with. it's an old graphics card but it does the job for me. to briefly describe what happened: my old power supply burned out and I bought another better one (surf shark 500w 80plus), when I connected it and plugged it in, the computer turned on but the image on the monitor was black. I disconnected the monitor cable and plugged it into the second monitor input, after which it was able to run, but I had transparent blue vertical lines on the screen, I thought that reinstalling the bios would solve the problem, but it turned out that I made it bigger. now the computer starts up, the graphics fan also spins, but the screen is black. I don't have integrated graphics, and I read on the internet that shorting some of the pins (1-4, 1-8) can reset the bios, but honestly I can't find out which chip and which pins it is, there is very little information on the internet about that. So I would ask you for any advice please. thank you in advance. Peace out.

Read through this.

Flashed an R9 270X and now it doesn't get picked up by amdvbflash

Basically, I was testing some BIOS mods for the GPU as it had artifacting and crashed, so I made a BIOS mod that got it stable by disabling half of the VRAM, however I was trying everything to get 7 chips usable instead of just 4, as 1GB is quite constraining. That's when I came across an ASUS...

Also from what is described, why did you not try a different monitor before flashing?

I've tried. The monitor is good.

There is 3 chips, which one I should try?

If it had blue lines it was already dead.
