TV WAS WORKING FINE. WE LEFT THE ROOM FOR AWHILE AND CAME BACK. WE NOW HAVE NO PICTURE OR SOUND

SOURCE: Mitsubishi vs 5051 rear projection tv sound but no picture

No video but good audio Mitsubishi VS5051. Check R509 and R 519, 100 ohm resistors located on the main PCB near the flyback transformer. Also bad connections on any of the yokes and the vertical output IC will cause the same problem.

I just had this same exact problem. I looked for an answer on here and could not find one. So I took the back off, vacuumed and cleaned everything out with the hose on my house vacuum, cleaned the bulbs and wiggled them around some. Voila !!!! lights on and all is working fine and better then ever. I hope this helps someone fix their problem. Just saved me tons of money and a morning of hassle.
