SOURCE: How to change lamp on Hitach 60vg825

Yes, you are due for a lamp. Save yourself some money by ordering just the bulb p/n UX21516 (instead of the whole lamp assy), install it yourself. There are lots of us that sell these bulbs far below what the assy costs. Make sure it is an OSRAM bulb though.

SOURCE: Lamp Replacement Problems for Hitachi 50V500A

I'll tell you what I tran into and how it got resolved...
I experienced the same problem , with the blinking light...
Purchased a replacement lamp..
It didn't work(After market Universal supposably)..
Well..Come to find out.The Replacement lamp's housing looks similar, but the connecters that come out the back of the housing weren't quite long enough to trigger the microbe that activates the lamp in the Television.
Luckily I had the original lamp and it's housing that came with the television..
Took the bulb out of the new replacement lamp
Placed it in the original housing , and BINGO..It worked and is still working...

SOURCE: lamp light

Check the lamp switch that is located inside the door. Place the lamp in, and stick a flathead screwdriver in the slot (just make sure it moves) hold it there, and turn on the Tv. If that doesn't work check the new lamp, is it a generic lamp, if so they dont always work. If you still have your old orig lamp, take the old lamp out of that housing, and out the new lamp in the old housing. This should fix the problem.

SOURCE: Hitachi 32LD8700 - TV won't turn on although has power

The general problem with LCD type TV's is that the power supply fails. They are very sophisticated designs that are difficult to troubleshoot and generally best to just replace the module, but sometimes there is visible damage in some of the electrolytic capacitors (visibly bulged) and high voltage rated parts can be substituted.
Hope Ya Fix It

SOURCE: replaced lamp on Hitachi 50V720, still have flashing red light

Just make sure the Box (Lamp Enclosure) is pushed in firmly on both sides, left and right. Left side to hit the power connection and Right side to hit the little relay switch, Must be flush against that back side. It happened to me and I was kicking myself in the ***, a entire weekend went by with a brand new lamp sitting in the enclosure but not completely set in correctly with a flashing red light.

I have a 60vg825 hitachi ultra vision that has a blank screen with lamp & temp lights blinking whats the cause


There must be a defect. The device is in a "protection" mode and warning it needs repair. Sometimes an engineer can read what could be the error, when he / she sees the flickering of the light (frequency and or rithm)
If it is still in warranty, call the firm where you bought it.

Diagram for cooling fans that controls the lamp on a Hitachi TV


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.

Hitachi 60vf820 displays red flashing light above power green light and picture will not come on.


There are 2 or three things wrong with this T.V. Step one:
Make sure the Bulb is good by taking it out of your T.V. and inspecting it.
If it is bad...
http://cgi.ebay.com/Lamp-HITACHI-55VG825-60VF820-60VG825-60VS810A-LP700-/260779634020?pt=LH_DefaultDomain_0&hash=item3cb7ad6d64#ht_1679wt_1024
This lamp already has the housing with it, just swap it out.
Two, you could have a bad power supply- Repair is usually 240-280 bucks in shop.
3: You could have a bad fan. The fan on this T.V. that goes bad is a nightmare to get to and I highly recommend a service man to do it.

Power indicator /red/ and warning led/red/ are lighting after ea 15 sec. a lamp never start and fans goes in OFF mode. I checked power supply lines S5V,S-5V,S16V on the Main Board . I checked unit lamp...


If power indicator light red and warning indicator red flashing than according to user manual :-
The projector has been cooled down enough and the temperature returns to normal. When turning ON the projector the WARNING indicator stops flashing. CHECK AND CLEAN THE AIR FILTER.
Experience:- 1. if the temperature is very low than temperature sensor maybe misbehave.
2. If anyone fan not working
so please you check fans.
(If lamp or lamp ballast unit faulty than after a time period the lamp indicator light ON not a warning indicator. I experience many times if any fan in projector are broken or jamed the temperature light if present otherwise warning light ON or flashing)

Main lamp Stops working.


it does sound like your lamp due to the led's. Check how many hours you have on the lamp. You should be able to do this in 2 minutes. Also check to see if you if you need to clean your filters.
