Hitachi tv blew fuse during power surge changed the fuse

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

SOURCE: Got a Hitachi rear projection model # 50ux58b.

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

Can you find out what Led is not on or which comes up and goes out? Most of these sets have convergence problems. Or Power Regulators.

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!

ok , on hitachi pro tv is very common with bad power supply u may want to replace the voltage regulator which is next to the fuse u already replace , also loose connection on all the power supply seccion , also u may want to check the resistor close by the convergence ic 2.2 ohn if this are smoke replace stk392-110

I have a Hitachi, 42 in. plasma ultravision and this morning I could not turn the tv on. No power.


check the branch circuit of your convenience outlet..the circuit breaker may have tripped..try to connect other appliance to the outlet where your TV is connected..this is to ensure there's power in it..if you are certain then that there's indeed power from the outlet you are sure that the TV is not working..check TV fuse and replace if blown..check resistance between the plug terminals after fuse replacement..if resistance is low, change voltage dependent resistor (VDR) with same value..it is a disk type resistor that looks like a big ceramic capacitor located just after the fuse..either blue,black or red.blown fuse may be due to power surge during the night..

Hitachi 50GX30B 50 in. Rear Projection...tv won't turn on since electricity went off & on


I have worked on several of this model for power surge damage. Usually what I find is a blown fuse, a shorted regulator i.c. and possibly a blown bridge rectifier(diode array). On rare occasions you can solve this problem by replacing only the fuse, but if the fuse blows when you plug the set in, you will more than likely find above mentioned parts have failed. The best thing to do is to call a repairman but if you have an ohm meter you can test it yourself:1.Unplug set and remove rear cover.2.Get spotlight and look closely at where power cord connects to circuit board.Small glass fuse will appear black if open usually.Otherwise,test for continuity, or just replace it.3.After replacing fuse plug power cord back in while looking at fuse.If you see an instant flash, fuse blew again meaning you will need to obtain parts in power supply and solder work will be required. That is probably as far as I can take this other than saying that you might first want to look at underside of circuit board to determine if major surge damage has occurred. If it has you will immediately know because it will have burn marks all around a/c power supply. I hope this helps, Russmann.

Power Surge at Home


This time it came in on the cable, the clue was the cable box also blew. So if you had a cable surge supression device...for HDTV, I think you would have survived the second surge.

I do have the technology. It is a F-connector type and will handle HDTV signal.

power surges generally damage diodes and capacitors causing the fuse to blow, any reputable tv shop can repair for a fraction of replacing this set.
