I HAVE AN OLDER HITACHI PROJECTION SCREEN IT IS AN ULTRAVISION. SOMETIMES IT WOULD NOT TURN ON BY SWITCH OR REMOTE. IT IS NOW NOT TURNING ON AND THE LIGHT ON TE FRONT TURNS ON AND I HEAR THE SPEAKERS ''CRACKLE'', AND THEN IT GOES RIGHTBACK OFF. ALSO SOMETIMES WHEN WE TURNED ON THE TV TO WATCH TELVISION WE HAD NO SOUND BUT WHEN WE PUT IT ON THE VDEO SETTING FOR DVD, WE HAD SOUND. I TEN DSCOVERED IF I TAPPED THE BOTTOM RGHT REAR OF THE TV (RIGHT BEING FACING THE TV). I WOULD LIKE TO FIX THE TV BECAUSE I REALLY LIKE IT. I AM DISABLED, (STILL AWAITING MY DISABILITY ****), AND DO NOT HAVE ANY MONEY FOR REPAIR, AND I AM HOPING THAT SOMEONE WILL KNOW THE PROBLEM SO I CAN SEE ABOUT GETTING THE PART FRM A JUNK SET IFI NEED TO. I AM HOPING I CAN FINDTHE SOURCE OF THE PROBEM A MAYBE CLEAN OR RIG IT TO WORK. I READ AN ARTICLE ONLINE THAT SAID IT MAY BE T BLAST BOARD, IF THAT IS IT WHERE IS IT LOCATED.

please check all the lights that are in the chassis hitachi puts led in the chassis so that if one of the lights are not working then u know that circuit is bad. now there is 2 things that hit has wroung in the units and that is a 2kv hv cap of the horiz output transistor that burns up and kill the power supply look for a small black or brown fuse it will not have glass on it it is rt behind the reg ic in the center of the chassis it allwas opens up because of the hv cap doonot run the tv without out that cap it will overload the horiz drive and will burn upo the horiz output but u have a very good ctv ther if u fix it will last u a long time and it is a very easy tv to trouble shoot.
