Black screen on Sega Saturn VA0.5

[belek94]

Hello Everybody

I have a Sega Saturn with a VA0.5 board revision that doesn't give video anymore. All I have is a black screen and no sound. It has not been modded. My monitor detect a signal but nothing appear. Disc is spinning by the way.
I know that a lot of those versions are doing this at a certain point for no reason. I came across a lot of FB post with the same issue.

This is what I tried so far:
- replace the battery
- Recap of the PSU
- Recap of the whole MB
- Reflow the AV connector pins

But still no luck.

What Can I do ?

It's hard to say, those VA0/0.5 boards are flimsy like that. The problem isn't the lack of video output, it's that the initial boot code is not executing for whatever reason. Could be anything from clock issue (the PLL chip is terrible and can easily die) to, well, anything else.
