I have not seen this model Hitachi but I have never seen one with 2 fans for the lamp---in all cases there is usually only one-

Hitachi only offers service manuals online and only to authorized repair shops with a user name and password. If two fans ARE involved it is unlikely both would be bad---flying by the seat of our pants I would suggest if possible to check the voltage at the fans---or even spin them to see if they will suddenly work---dirt can cause a fan to slow or stop and the set would either shut down or issue some kind of "fan failure" or temperature warning.


I am willing to help as much as possible and I understand the desire for a diagram but that is unlikely.

Let me know if I can assist or such in any way---I do this here for free but am here to help people.

SOURCE: My Hitachi 70" LCD will not turn on

Take the door back off and look for a safety tab somewhere on the door that will activate a small safety switch, the tab will stick out. Maybe you broke the tab off or just didnt get the door on correctly. Try that and let me know.

SOURCE: installing a lamp in the Hitachi 50V710 projection TV

The lamp is on the bottom left side. Remove the plastic piece that goes across the TV below the screen. It will snap off. No screws. Remove 2 screws to access the lamp carriage.
Make sure you DO NOT touch the new lamp with your bare hands.

SOURCE: cooling fan no longer working on tv

Chances are good that it will work. The only catch is that one of the wires are monitored by the protect circuit. If the wiring is different it may not work. I would try it though. Nothing bad should happen. Make sure that if it does work that the fan is blowing in the correct direction.
Hope this helps,

Bought a Hitachi 55VF820 at a garage sale and they said it wont turn on even after replacing the lamp.


I dont know the model but general trouble shooting might work. See it you can download the manual and or look at the web site for the trouble shooting section. Check the power cable for breaks, some can be hidden inside the insulation. Look especially at the ends where the wire gets flexed the most. Check if there is a fuzz and it is good. See if there is a removable panel and look inside for bad, burnt, of exploded parts. Read the bulb replacement section of the manual and remove and replace the bulb as instructed. Read turn on instructions and or break-in instructions. Give it some time to warm up.

2 notes; Do all this with out plugged into wall (for safety).
Be sure to try to not touch the bulb and clean it with a lint free clean towel. They are very sensitive to oil or dirt from handling. .

well..the control board has this sort of issue. sometimes, if you turn if off long enough to reset itself, this may clear..otherwise, it's a replacement of a non inexpensive component..

what's your technical ability like?

Cooling fan won't turn off.


this set has more then one fan; one fan will run all the time to cool the digital circuit board---if it is the actual LAMP fan then you have a problem---the digital fan is very small and not located near the lamp.

Problem with tv


Pretty typical for lamp life. Buy a new bulb (not the whole lamp assy) from us (sedonix.com) or one of the many bulb sources on the net, install it yourself and save a lot.
