Question about Hitachi 50V500 50 in. HD-Ready LCD Television

Hitachi 50v710 turns off after about 1 minute

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

I have a Hitachhi 52


Sorry to say, But its probably the light engine.Hitachi has had big problems with this, its all over the net about this kind of problem. If the set is not very old, you may try to call Hitachi and complain, They did replace mine in my 50V715 but I had to pay a service call of $300 to have an authorized dealer replace it. Hope this is helpful.

Hitachi 50v710 Yellow spot


I found out that Hitachi has a class action law suit against them for the light engine problem. I called them and asked what they were going to do for my tv which is out of warrenty. The reply was that they would pay for new light engine. I said what about labor. No they would not pay for labor. I asked to speak to supervisor. I was told by supervisor that the tv had to be inspected by certified repair person. Cost for this was $125 but would be applied towards the total labor cost. Repair guy came to house walked in and said he did not even have to turn tv on to know the problem. We called Hitachi to set up shipment of part. Hitachi told me at that point that they would cover all labor costs also. Part has been installed this week and tv is like brand new set.

Hitachi 50V710 Yellow screen


I contacted Hitachi (800-448-2244) on 02-18-09 and spoke with customer service rep. name Joyce. I explained the yellow in the middle of the screen and told here a Tech came out and said that the problem was the light engine not the light unit. She immediately said that she would send a brand new Light Engine to the repair company that diagonsed the problem. She said I would have to pay for labor. The light engine is a $1000+ part and the repair company said labor would be $300 dollars. The key is you have to say that a tech looked at it and diagonsed it as the light engine and not the light unit. Find a repair company in your area and let the customer service rep. know that they looked at it about a month ago and you can't find the paperwork. The customer service rep will then recommend a company in your area to come and look at the TV. The tech company will probably charge a tech fee $100+ dollars, and about $300 for labor, all total $400 for parts and labor is not bad when the Light Engine itself is a $1000+ part. Hope this helps.
