Question about Mitsubishi WS-65809 65" Rear Projection Television
I have same problem as another member, tv turns right off seconds after turning it on, green timer light comes on and goes off, no picture comes on or sound, just a little power zapping sound every time. it worked fine last night!!
Check 2 5amp chem fuses. in middle of tv. yellow or orange in color . if bad replace the 2 stk convergence ics and fuses.

There is a resistor by the high voltage transformer,it has low value and it opens for no reason,he is likely open and does not let the set stay on,if you are familiar with tv service you can replace it and while you are down there check for any over heated areas and resolder them specially the convergence IC.This resistor is located in the back edge of the chassis in the board in the right side and it might be hidden by a plastic casing that covers the high voltage transformer.If you are not too familiar with tv service you should seek the help of a servicer.Let Us know how it goes or if you need more information.

I had the same prob w/ my Mits 65 rear proj. Refused to turn on, light only blinked. Was able to correct for free. Opened access panel & noticed wood holding 3 main lenses (Red,Green,Blue) was loose/warping. Tight'nd everything up with a phillips. Problem solved and picture is better than ever. While at it I dusted off interior. Check your tv b4 calling someone. Sometimes the solution is simple.
