PS1/2 modded ps2 wont play burnt discs

[TripleTrevor]

I got an old ps2 from my friend, and he had lots of burnt ps2 games, I tried to play one of the burnt games but it did not run. I tried to run official games, and it works.
Its a modded ps2, it played burnt games before.
its a slim NTSC ps2, I got no clue what mod it has, I know it played burnt discs before and I have those discs.
Any ideas?

Could be that one of the wires of the chip has come lose, lens dirty, laser on the point of breaking.

do the games need to be esr patched before you burn like free mcboot does ?

Im not sure if its even chip modded or soft modded, how can I check?
If the problem is in the lens, the official games would not run too right? Official games works great.

I got no clue... I got the burnt discs but I didnt burned them.
Beside, I have no idea what is esr patching.

its a program used to patch ps2 games before you burn them to make them run.

Soft modded just turn it on with the memory card in and no disk its it comes upto the free mcboot menu its soft modded.

Nope, modchips don't require that.
