Query: Replacment lamp damaged my optic block 300 bucks

I ordered a replacement lamp for my sony wega kdf 46E2000. back in june. just so I had a spare on hand. I usually order official sony parts but decided to try and save some money this time. This is the 3rd time I have replaced the lamp since owning my tv. since 06 or 07. Now after replacing this lamp I got a red bar at top and blue at bottom of tv screen. looking at this issue on various forums and after contacting sony. I am going to need a new optic block for 300. can't even return this lamp for my money back now because it's past the july return date.learned my lesson always purchase OEM parts from now on
