I have had my 360 modded a little over a month.

Backups were playing fine until just recently. now it just tries to load for a few sec then i get the open tray. It still reads my originals fine.

I have the Liteon 74850c drive, and its flashed with the lastest firmware LT 1.1. I also use verbatim disks. any help would be great.

Well I fixed the problem as of right now, I dont know if it will be a permanent fix though, but I am able to read my backed up discs again.

Anyways I used the pot tweak because i didn't think my laser was burnt out YET. when i first tested the pots with the multimeter it read at a staggering 7.6 which at that point I thought i was reading it wrong where the guide said it should be anywhere from 3.0 to 4.2. though i saw other peoples start at around 5. So i first tweaked it down to around 5.2 nothing happened still wasn't reading the discs, then i put it around 3.2 and it started reading them. I think the next step if things go a miss again will be to buy a new replacement laser. Anyways just thought I would discuss my triumphs

Just wondering if anyone has had to do the pot tweak if their laser has burned out?

I ordered a 141X laser off ebay. Just to clarify my curent laser is a 141XX the benq 141x laser is compatible? anyways here is hoping I dont have to use the new laser, but its there for backup purposes.
