WD-Y65 Black and white stripes only on screen. Looks like a bar code. Audio works.

SOURCE: my mitsubishi wd-y65 has sound but screen is black

You are SURE the lamp is good....well...if you say so. However, it sounds like you have made audio connection but no video connection (or lost it or is incorrectly set). Try other input modes. See if you an bring up "setup". If so...you screen/lamp is working.

SOURCE: just replaced the lamp on my WD-Y65

Apparently there is a separate "reset" for the lamp..if u google your owners manual & download it (save it to ur computer!) you should be able to find it there..or you can always try doing a search on www.youtube.com to see if you can find a video to help...I have the same TV..I love it but apparently there is a bunch of common problems with the TV, and having to replace the lamp and or housing is truly a pain & expensive!!! If you google the TV with the model you can find alot of useful info about the issues this TV has!
