Question about Hitachi Projection Televisions
These sets have circuits to detect internal problems and these circuits will shutdown the set or prevent it from coming on completely in order to prevent further damage. It is unclear whether or not there is a power problem. If this set is not under warranty, open up the back and look for capacitors that have bulging tops. That is one possible indication of a problem. There is no "fuse" that will fix this. Since the power supply is a "switch mode" type, there are a number of reasons for part of it to not function. This is not an easy problem to diagnose remotely.I would suggest that you request service on this. I don't have a listing for the model you posted, so I can only give you general information.
Keep us posted.

There are two power source on the TV's circuit. One is power supply for sound and the other one is power supply for the video. It seems like there's a broken/burned electronic component on the video power supply, normally its just a capacitor. However, uou may need to visually check the circuit board to identify which other part is totally defective or burned. If you can't do it by yourself, just bring your unit to a qualified electronic technician or to any nearest appliance service center.

Sounds like you may have a high voltage arc and / or leak . better to let a manufacturers qualified technician have a look at it this time . ask for an estimate after diagnosis and before repairs are made. factor age plus repair cost v/s a replacement tv . also in the area where i live most in shop repair estimates are cheap or even free . field repair estimates are definitely not . all tv parts can be replaced but, screen replacements can get expensive . barring neglect , abuse or a significant power surge you should not be having these problems on a tv so new. double check your warranty. most electronics come with 1 year on parts ,90 days on service. some warranty limitations are not allowed in certain states. also contact the manufacturer . in my expierence some of the better companies have honored an expired warranty partlialy and sometimes even fully on a relatively new product . after all they do have reputation to lose or keep . just be courteous and if your lucky they will be too. but if all else fails, i personaly prefer lcd flatscreen . oh , about the screen crack , clean and position your tv according to the owners manual . some of todays televison components are even more thermaly and chemicaly sensitive than ever . ie; window cleaner can whiten or even crack certain types plastics. finaly if you are not using a good surge protector now may be the time.
