Question about Hitachi 60SBX78B 60" Rear Projection Television
When I turn it on, n'thing happen. I open the back, and saw that when I plug it in, three or four green dios lights come on and than go out.My TV will not come on the red light comes on then goes off. my Tv is Hitachi ultra vision sbx 60in Model # 60sbx78b
Seems TV has problem in horizontal deflection section. If you know basic electronics and have good experience of TV repair then try to fix TV because electric shock risk is involve in TV repair.
You can have service manual of Hitachi 60SBX78B at Manual Zone for small fee.

You will need to call in a service tech as it sounds like your main board needs replaced.the greenn lights re supposed to stay on when the tv is turned on and they arent. call a tech and have them fix it for you it shouldnt be too expensive

Same happened with my Olevia 540-B11. You can probably find the details of how to disassemble the TV somewhere online. The problem is poor stress-relief on the cables that plug into the secondary (low voltage) side of the power circuit board (PCB). Once the back is removed you'll find the PCB on the left side with three cables connected to the very top of the board. These cables plug into four clips, 3 horizontal clips side-by-side at the top and one vertical clip on the left side. Unplug these cables, remove the PCB and re-solder the sockets (there are approximately 40 solder points on the back of the board). Reassemble your TV and it'll work just fine.
