Hi all!
This is my first post, and I mainly created this account to ask for support. So let me get straight to the point.
Today I changed the LED of my NES to a seven-coloured flashing one. And it turned out awesome, you should really see it! (But since it is a very basic mod, I assume you all have seen it before

.)
However, since I reassembled it, the only output is a continuous white/gray screen. It does not matter if it has a game loaded or not, or at what angle it is inserted. I tried several, and I just get the same blank screen all the time.
Before this, it worked perfectly fine. No problems whatsoever.
I have disassembled some other NESes in the past, including this very one to disble the lockout chip. Neither was it the first time I changed an NES LED.
What could have gone wrong?
Sincerely,
Jitse
