I HAVE a Toshiba dlp rear projection tv 62hm15. The bulb recently went out so i replaced the bulb, but i also push the reset button on the tv(not sure why). It seems like now the picture isnt as good. Especially when i play xbox 360. The display used to look good at 1080i, but now it seems like at 1080i looks more like 480i.

Should i calibrate the t.v?....will this fix it or did i mess up the system settings?....if calibrating will help, what should i use?...

Digital Video Essentials - Home System Setup for NTSC DVD .....will this help?

it seems like the lines are all jagged now...they used to be smooth, but it really looks like 480i.....please help...
