Did the bulb break or just get dim? if the bulb broke then you might have a piece of glass down in the engine if the bulb just got dim you might just have a piece of dust down in there you really should have atech take alook or you could damage your engine and that would be around 500 dollars

Contrast really dark but seems to improve after the tv has been on several hours


Hi:
You may have a problem with the inverters in the unit, they are responsible for lighting up the back panel. Check or have checked the power supply voltage to the inverters, should be around 18-24 volts DC. Also leaky capacitors on the power supply will cause this issue as well as leaky or puffy capacitors on the inverter.

Screen has green tint, it is an LCD 42 inch


First of all, that is not an LCD tv. It is DLP, which is a common mistake because the picture is very similar. DLP tv's use a high-power lamp that reflects light off of thousands of tiny mirrors into a spinning color wheel which gives the reflections color. Each little mirror is one pixel, which can be any color depending on the hole that it goes through on the color wheel. The color wheel may be spinning slower than normal, which could make all of the light go through the green filter on the color wheel, and give your screen a green tint. Have a trusted mechanic take your tv apart and dust the inside. If that doesn't fix it, you may need a new color wheel or bearings for it (that help it spin). You should not pay more than $200 for a bearing replacement on this tv.

Thanks for asking.

Tv color not bright enough and just replaced lamp


Clean the small mirror in front that projects the image onto the rear mirror. The Rear mirror always stays good but the front small mirror gets dusty and the colors and bright levels get affected and appear dim.

Have a green tint over 90% ot the center of the screen


I had the same problem with my 60V500A about a year ago. The screen got a red tint in the center and the image was fuzzy in that area. A new lamp didn't solve the problem. I did some checking and found out that the original light engine used in this model had a cooling issue that could cause the light engine to overheat and distort the LCD panels. My warranty had run out more than a year before this happened so I figured I was screwed since the light engine was so expensive. I decided to call Hitachi tech support and see if I could get a discount on the cost of a new light engine since the cooling problem was a known issue for this model TV. I calmly explained to them that I was aware of the cooling issue in the light engine and that I felt like a $4000 TV should last more than two or three years. Tech support gave me the phone number for my local authorized Hitachi service center and I gave them a call. Once the technician confirmed that it was the light engine that was the problem Hitachi sent him a replacement light engine at no cost to me. I was WAY past my warranty period so I still had to pay for the labor to replace the light engine. $300 for labor was a lot cheaper than buying a new light engine or tossing the TV and buying a new one. I have to say that Hitachi earned my respect for admitting there was a problem and doing what was needed to correct the problem more than a year after my warranty had expired.

Colors have a blue-green tint


Try this first:

Press: MENU, 2, 4, 7, 0, ENTER

This will factory reset your tv. Be aware, this will erase any NetCommand or user-created features you have set up on the tv.

Check your results.

If you don't see a change, begin to suspect either the lamp, color wheel or light engine.

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.

Green tint I can't seem to fix


Hopefully someone on here has a manual and can tell you exactly where the tint controls are. Also need to try adjusting the color level, turn it clear down so you have a black and white picture.
Is the picture still green over the screen with the color control
set clear down to black and white? If it does, you might
have an issue with the green gun going out or problem in the
circuitry to it.


By the way, the best way to adjust the picture settings on a
tv are to first turn the color control clear down, then adjust
brightness and contrast for best black and white picture, then
bring up the color level to where it should be and adjust the
tint for best red/green ratio.
