Question about Hitachi 46F510 46" Projection HDTV
I had a power surge and it blew the fuse and several other things in my home up. I changed the fuse and it still will act like it dont want to do anything. i checked it with a multimeter and i was getting power after the fuses but it still does nothing. I have no clue what it could be. I dont believe the problem is the fuse as of now i think that there maybe something else wrong does anyone have any suggestions
the three guns that the lenses drive operate at 28kv.
there are very high and dangerous voltages in a tv set.
you can look for the fuse main pc board by the power cord..if it is black,there is a major short.if it is just barely blown,change it.
the fuses are 3ag glass type and just pop in. use a set of rubber gloves and insulated pliers.. tvs are DANGEROUS

SOURCE: Hitachi 51F510 with NO POWER
Something is preventing the power supply from operating:
Possible causes in order of likelihood:
1) Convergence amps failed overloading the supply (See if you can disconnect them)
2) High Voltage circuit has died. (Right on schedule since your TV is 10 years old)
3) One of the CRTs has shorted
4) The power supply itself has died (Is there a lot of dust covering it?)
See if you can isolate the failure by working down the list.
Hope Ya Fix it!
