DRE Problem I had

[Afterlife]

Some of you may remember the post I had a few weeks ago about my DRE.

So after taking it into a repair shop I got a call that it was working fine and I could come pick it up.

He didnt have to change the lazer either which is awesome news. But once I got there I had brought 3 games, a reg DVD game, a Copy of that same DVD game, and an original ps1 game. DVD movies now play in it no problem, ps2 originals, as well with ps1 originals work fine, ps2 copies(havnt tried ps1 copies) still get a DRE. Because of this the guy didnt charge me which was awesome, as now my ps2 functions normally but wont play burnt games which is annoying...

So now I have a few queries. Is it the mod thats messed then, or is it because I tampered with the lazer alignment?

The ps2 is booting like a reg ps2(its fitted with a magic 3.1), so im not sure if the mod chip is even being recognized, but after a few tests i think it is.

Usually if it cant recognize the disc you get the red screen saying to put in a real ps2 disc, but it doesnt give me that screen it just gives me the DRE screen, so the mod must be functioning.

So I dont know wether I shud take it back to the guy who fitted the mod for me to see if he can fix it, or open it myself to see if all the wires are still connected, or just sell it for what I can, see if I can get enough to get myself a game cube or something.

If anyone has any ideas or if they know of a way I can fix this I would appreciate the help.
