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

2 Answers

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

Have a 60V500A (S/N V4E015203) Hitichi DLP that had a very dim picture. Was told it needed a new lamp. After replacing the lamp, the screen got a green tint over the picture about the size of a basketball in the center of the screen which changes the color of everything under the tint. If the man has a red shirt the green tint changes the color of the shirt to blue. The rest of the screen had normal color. After about a week, the green tint now covers about 90% of the screen with normal color just around the outside edge of the screen. Was told it is probably the lamp engine and would be very expensive to replace. I will soon have the price of a new TV and still may not have a working TV. Any suggestions Jim

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.

These sound like bad light engines. They are expensive and need to be replaced by a technician.

Panasonic DLP TV has huge yellow blotch covering most of the screen


SET uses a optical light engine--lamp which is quite hot shines into the engine---blue is first to get the light and heat and is usually first area in the lens and baffles to get damaged(loss of blue leaves red and green which equal a yellow screen.

You have a damaged light engine.

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.

DLP RCA HDTV is displaying bars from top to bottom of screen, with green tint. Is this the light engine going bad?


Hi

Thanks for using FixYa. This issue can happen due to a faulty light engine or due to a a faulty DLP Lamp. However, it can be an issue with the video driver card of your Card. I'll suggest to use a DVD player and check if the tint is still there. If the tint disappears then its an issue with the video driver card.
However, if it doesn't correct the issue its either a DLP Lamp or a faulty light engine.
Note-- Please make sure to turn off and unplug the TV for at least 1 hour (this will drain off current from all components especially capacitors) before you perform any repairs. Also note that the TV consists of very high voltages even when it is in OFF condition.

Before performing any repairs i'll suggest you to try and reset the TV by unplugging it for 8-10 hours.

Please do accept the solution if the issue is resolved or else revert for further assistance.

Thanks
Rylee

Screen Green Tint


Turn down your color and see if the screen has a normal black & white screen. If it doesn't then the CRT is bad (picture tube). If it is black & White then you have a either lost your red or blue.That problem will be in your video driver circuit of which a service center can handle.

Green Tint on half of the screen


This is most likely a defect in the optical unit (about $1500.00 part). If out of warranty probably will just have to live with it. Those op units are also hard to get.
