This is not something you can just fix yourself unless you have extensive knowledge of repairing this product. It has lots of parts inside of it that are very delicate that only special repair locations can work on it. Otherwise they could even do more damage then good by tinkering around like an experimental project.

It sounds like somethng wrong with the motherboard which can be anywhere from a $50-$xxxx? Unless you still have an extended warranty...then you lucked out!

You can contact the manufacturer regarding parts or even service. Some times they can offer a flat fee for service at a local service center.

Let me know how it works out for you.

I have a Hitachi 50v710 it has a yellow tint in the middle of the screen can this be fixed thanks


This tv is an LCD projection one. in it the image is generated this way: a bulb makes the light; this light is divided then passed thru 3 small LCD screens; the 3 pure color images are mixed together by a prism then passes thru a set of fine plastic lenses (this is called the optical engine) ; from there the final image is projected on a screen.
The entire image quality is determined by the quality of the optical engine - if something goes wrong with it it's clearly visible on the screen. In your case the heat of the bulb has deformed the first lens, and that has caused optical aberration - color shifting.
This is fixable, the optical engine will have to be replaced - you can't replace just a single lens, it's a sealed unit. Unfortunately it's not a practical solution: a new optical engine will cost you over $800.
Use the tv as is until you can save enough for a new one.

Lines across screen


If the lines are slightly diagonal and in red, blue and green you have a problem in the ABL circuit. if the lines are only one color you may take the front grill cover offf and remove the panel. look fro the black box 2 inches square with 6 little controls on it. 3 are for focue 3 are for screen the middle on of the screen is the green adjustment the other 2 should be labled r and b respectivly. what ever the color of the line turn the control labeled screen and r b or g for that color ever so ligtly counter clock wise.

42HDS69 42 in. Plasma has several thin green vertical lines in middle of screen


If the set is still in warranty, call for warranty service. If not and you feel comfortable working on the set, carefully open up the back and reseat all of hte cables and connectors. This can be caused by marginal connections inside the set.

Keep us posted on your progress and results.

Hitachi Class Action Lawsuit


I have a Hitachi 50V710 with a yellow-greenish spot in the center of the screen. It appeared there about a year ago. I have been putting off getting it repaired because money has been pretty tight. And they told me that my warranty has expired. They also said that it would cost over a thousand dollars to fix the problem. I purchased the 50" TV 09/09/04 for a total of $3336.88 what a rip-off. Now the whole screen has a green tint and the yellow-greenish circle in the center looks brighter. I wonder if it is even worth getting it fixed? What will go wrong with it next? Its a Lemon.
I really regret not buying the 52" sharp that was setting next the piece of **** that got suckered into buying. I know I learned one thing out of this,
" I WILL NEVER BUY HITACHI BRAND PRODUCTS AGAIN! "

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!

Pink cloud covering most of the screen


If the pink spot appears as mostly a circle in the middle if the screen then a light engine is needed. If it is an even coverage than possibly just a memory initilization needed by a technician.
