Television and Home Theater

I have a mitsubishi 65 inch h.d. wide screen  projection tv, model # ws65315 . i really love it ,but you wouldnt know that concidering what i did. I left the aspect ratio 4:3 on for more than 15% of the time, now i have two black transparent 4 inch lines from top to bottom on each side. i dont really notice them unless their is a bright background. I would like to eliminate the lines,it interfears with cinematic pictures.

Hello my first time here searching for answers, thank you.

I recently picked up this projection tv project for myself. It has great

sound but not a whisper of a picture. Its a little old made in Dec. 91

I probably won't be able to find replacement parts but I am willing

to give it a try. I thought someone might be able to help me with

some ideas, other than spending hundreds of dollars at a repair shop.

I have got it apart and started cleaning it, and was wondering

can you play video games on front projections for a little at a time

and if you can how long
