Re: color adjustment issues.

You have the infamous "red cloud" as they call it and no matter what you personally do to the TV, it will not resolve the problem. The problem is you have a defective light engine and Hitachi is aware of the problem. We started noticing the red cloud in the middle of our TV (we have the 60v500) about 2 months ago and it got worse. After LOTS of online research, we were convinced it was the light engine. When we called Hitachi, they claimed to know nothing about it but THEY DO! They did give us the names of two certified Hitachi dealers in our area and when the tech came out, he could tell within one minute that we had a bad light engine.

I then called Hitachi back and told them that the tech confirmed that we had a bad light engine and all of a sudden, they knew about the problem...imagine that! They told us that they would call the dealer we used and confirm this with them. They did call the dealer and within 2 days, the dealer had a brand new light engine, sent to themby Hitachi, and they came out and installed it...TV is like brand new.

Here's the kicker...there's always a kicker. If your TV is not still under warranty (ours is 3+ years old so ours is not) Hitachi will cover the part...around $1500 but they ask you to cover the install by the dealer. Our install was $400 and they did the install in our home...they did not have to take the TV into their shop. We felt like paying $400 for a $3600 TV (price we paid when we bought it) was worth it!

One last thing, deal only with the Hitachi Customer Relations Department...NOT CUSTOMER SERVICE. Their regular customer service folks will have you chasing your to speak. The Customer Relations Number is 800-654-7013. If you're TV is not under warranty and you're willing to spring for the install, it's well worth it. Don't let any dealer tell you that you will have to buy this $1500 part. Hitachi will send it directly to them and you should only pay for the install. Good Luck!

Color issue

download this manual
see page 59,60,61,62. The problem can be the lamp
After extended use, if the TV picture turns dark, the color looks unusual or LAMP INDICATOR light turns on, then it
is time to replace the lamp with a new lamp.

When you replaced the lamp, was it doing the same thing? I doubt the lamp was bad, maybe but doubtful. I would try to adjust the color on it. What kind of TV do you have? I need the model and year.

I replaced the bulb on the unit and still have a blue spot on the screen of my Panasonic MODEL PT-52LCX35

most likely needs to be manually adjusted

manual convergence should fix the problem if it does not the set most likely either has a bulb burnt out or a bulbs power / focus needs to be adjusted by taking off the panel and finding a 6 screw control panel


should look like that 3 screws in a row on top of another three screws each of thees control the power and focus of each color this is a somewhat delicate process and is a huge pain on larger tvs that you cannot completely see the picture or color while you are directly under in front of it so I had my gf come in the room and sit across to let me know which color was doing what if you dont have someone you will need to check after each adjustment

now the diagnostic
as i said each screw controls a colors power and focus the focus is used if you see an outline of a color around pictures if everyone looks like a dead jedi with a blue aura around them the blue focus needs to be adjusted and so on for each color if you skies or blue screens seem feint your blue power probably needs to be turned up and so on for each color

if through the course of this you can see the bulbs and notice one is out your probably looking at dealing with the color issue until the time you can purchase a new tv as the cost of the bulb and the technician needed to install it as they are wired to a circuit board and requires technical knowledge and tools

hope this helped
