there are several fusses in a hitachi located in the power board if your lucky one of them took the hit you can , or have atech look for you the gma type fuse are avail at Radio Shack or your local tv shop
if ure handy pop the back off and there should be a main power board and a fuse on it, make sure you use the same fuse if it is blown do not stick another type or size in it, put it back together and turn it on if it blows again it will be somthing else if not it should work
after a power surge if you dont have in on a surge protector it probably fried the main board in the tv so it wont work anymore..woudl probably be cheaper to buy a new tv than to try to repair the one you have now
I the same problem and I found that the Capacitors used on the power supply portion of the circuit board were leaking and/or bulging. These parts were failing and as a result the problem worsened with time. If you are able to remove and solder new parts on to the circuit board follow the following procedures. Or get a technician to do the repairs. 1)Make note of connections at back of TV.
2)Unplug power cord and other connectors from back of TV. 3)Remove back of TV with a Phillips (+) star shaped screw driver. 4)Note the position of all connections to the main board.
5)Remove circuit board taking care not to damage any of the components. 6)Locate parts CM806, 811, 812 & 817, all 1000 uf 10v capacitors.
7)Remove and replace parts with capacitors of equal physical size that are (1000 uf ).I would recommend a voltage rating of 25v or 32v. Note that the voltage refers to the amount of voltage the capacitor can handle. The higher the better.
8)Reinstall and reconnect the circuit board. 9)Replace back on TV and setup the unit as before and you’re done. 10)Enjoy!
LOT OF TIME WHEN YOU LEAVE IT OFF FOR THE NIGHT DISCONNECT POWER CORD DEFECTIVE SURGE PROTECTOR IS NOT GOOD FORE EVER PLUG TV IN THE WALL WITOUT THE SURGE PROTECTOR IF IT GOOD CHANGE THE SURGE PROTECTOR FOR NEW ONE CHEERS
Mondern day television sets have to user serviceable parts inside them as they are all solid state and you will not ben able to look at a set and see something wrong. These sets you need specialized test equipment to troubleshoot relace and repair parts inside them. Your set suffered what alot of solid state electronics these days . A power surge will usually blow out the power supply section of a set and who knows what else. If your not a tech a TV set is not a place to be experimenting with anything .. best thing to do is call a tech to trouble shoot and give tyou an estimate. Now if you mailed in the Registration to the surge protector, and the tech writes down that this was all caused by a surge, then you shouldnt have any problems collecting what you laid out for a repair. The surge protector company,if the repair cost alot ,will contact the manufacturer to see how much the parts listed ncost and if these parts could go bad when a power surge to stop peeps from padding there bills. Make sure you get a complete itimized bill not just repaired power supply on a bill cause you wont get paid. Also make sure you call an authorized repair place for the manufacturer of your set. as its not 100% necassary, but much more legiter in the eyes of the power strip company. Good Luck
