I've got a Hitachi 50v710 that is about 3 years old. About a month ago I replaced the bulb and housing unit and it has worked flawlessly since then until yesterday. Son was playing video games on it and it simply turned off on him. Now the TV will only turn on for about a minute at a time before it turns itself off. When it does turn on you can definitely see the picture clearly until it powers itself off. When it does power down, it takes an abnormally long time for it to finally power all the way off. We're talking 3-5 minutes. As soon as you turn it back on, same situation repeats itself. I've taken the panels off and reseated all connections and used compressed air to remove dust but still having the problem. Any suggestions???
I think your replacement lamp is not a Phillips Original Lamp used for you model. Third party lamps work well only for a few weeks once they reach their lifetime your TV acts as you described. Beware these lamps can damage your television in many ways. Check lamp for dark areas especially around the bulb tip. Good luck...
This is a very common problem with lcd and projection screen.. what is happening power supply are being over loaded manufacture did not think about the long term use of game and computer graphics which put out a higher amout of graphics which over works the power supply over time... but they did make them easily replaceable with in unit thier usally connect to main board with plug lamen terms...
if possible take unit apart locate wire from the socket for power cord follow wire to power supply disconnect.. socket maybe be directly attached to powersupply module either way detach locate part number on board call manufactuer order new one or take it to your local tv shop and have them replace items onboard that are bad

Sounds like Calibration is needed on the projection internals. Your TV uses a rear-projection system and the problem is either in the imaging LCD Unit or the light filter. I see in a previous thread you have changed the bulb. You can invest in a voltage regulator to keep the hardware in factory condition.
Also you can burn a DVD of a stuck pixel remedy video and run it on the screen with full brightness and full contrast. This is used for plasma burns and stuck pixels on conventional Flat panel TVs but can repair color issues with projection systems. This therapy is focused on the imaging unit between the projector and the main drop of your tv.

I would try to re-seat the lamp. Pull the lamp out, check it to see if it may have gone bad again, then put it back in to make sure the contacts are connected. Before applying power, unplug the TV for 5 minute, and then plug in/turn it on.
Most lamps, if bad from the factory, will go out within 3 months of use. It does happen, and happens more often than you would think.
If you have read many of the posts, you would have known not to buy Hitachi Telivisions or like me avoid all Hitachi products. There help line is not very useful, they just blow you off. I have never had a worse experience with other manufacturers. Take Onkyo for instance, they had a problem with a chip in their THX receiver and it was a year later ... I called their help line they located a repair store about 40 miles from where I live (in Texas that is not very long) and got my receiver fixed and this was 8 years ago.
Also use Consumer Reports to check the frequency of repair record for the product you are going to buy. In Plasma - Panasonic is a safe brand, in LCD's Sony or Samsung have good repair records.
Research the product before you buy it, avoid walking into a store have the salesperson direct you to a product. And then you save money if you order it online. Amazon online is very good.
I finally got information from the repair shop. Apparently it is the
upper and lower panel drive. The parts are supposedly not more than a
couple hundred dollars, though I'll let you know when I get the bill. I
do want to say that Hitachi was great when I called them. Even though
my plasma is out of warranty by a few months, they agreed to pay for
parts if I pay for labor. That just might keep me buying Hitachi
products despite the issues I've had with my 2 plasmas.
You have a defective light engine and here is what you need to do...we just went through this. You need to call Hitachi's customer relation department at 800-654-7013 and tell them the problems your having and that you think it's a defective light engine. They will initially act like they have no idea what you're talking about but will give you the names of some certified dealers in your area to call. Once you have a tech out from the dealer and they confirm the light engine problem (takes less than a minute) call Hitachis customer relation department back and tell them that a certified tech confirmed the problem. All of a sudden, Hitachi will say they are aware of the probelm...imagine that!
Hitachi will call the dealer and confirm this with them and they they will send the light engine directly to the dealer and Hitachi will cover the cost of the part (around $1500). All you will pay for is the install. Our install was $400...worth it to us since we paid $3600 for this TV 3+ years ago and it's been a great TV.
DO NOT let the dealer tell you that you will have to pay for the part. Hitachi knows about this problem all to well and they are replacing the part for free.. Again, you only pay the install. Please deal only with the customer relations department at the number I listed above. If you deal with their regular customer service people, they will have you chasing your tell. Hitachi customer relations will take care of you! Good Luck!
