I've recently gotten a dms3 installed (not a dm3 plus) by a modder. He seemed to use 30awg wires for all connections even the ground and power. So now all I get after the install is a ps2 that plays originals of ps2 games and dvd movies (these load without needing to press any buttons when starting up the ps2).
Ps2 backups give the red screen and psx backups show up as audio tracks. Now the modder blames that this could be a faulty chip. Unfortunately, I bought this chip from someone else not from the modder so he says he's not responsible for it not working after the install. But I spoke to the person who sold me the modchip and he said that this was from a batch of 3 where he installed 2 that worked perfectly fine.
I need help on what to look out for to make sure the install isn't the problem? What are some things can I check to make sure it's not the chip's problem?
Thank you guys very much for the help.
