Update, update!

Thanks to the kind help of hese, this A3000T is alive again. I will receive it soon and post pictures of the resurrected bad boy.

I am so happy!

Thanks to everyone for their help, I was very frustrated with this problem.

The A3000T will get a full restoration since the past owner painted the case in a weird greyish texturized paint. Will upload pics of that too.

Could you please explain what was wrong with this A3000T? I know it's an old thread but, less old than the Amiga, so any information could help me restore my not booting A3000T.

Sure!

I tried everything, reseating the socketed chips, change jumper config, tested volts on the power supply, and nothing. It had little battery damage, that I cleaned, but that was not enough. I ended up sending it to the user hese and he changed many components near the battery, then it worked again.

Read this entire post, try everything that is suggested...

The CPU, FPU and PAL chips were the biggest culprits. FPU caused yellow screen, CPU and PAL chips caused random gurus.
Interestingly you couldn't disable the CPU caches on Early Startup Menu with the faulty CPU, it hanged the whole computer to black screen.
