Question about Hitachi 50V720 Television

2 Answers

Color issue Purchased new 50v720 12-05 - heavy use - have sucessfully replaced 3 lamps. Current issue relates to picture color - which has turned "greenish" in hue with a noticable decrease in overall picture quality. Unit is powered by DirecTV HD-DVR. Similar picture quality with DVD's. Adjusting tint/contrast/etc. do not help. Ideas?

What you are seeing is the degradation of hte "light engine". This is normal with extended use. You can try blowing out the area with compressed air to clean out any dust. But any LCD based projection system is subject to this breakdown over time. Can you further describe what you mean by overall picture quality? Is it out of focus? do you see separate colors (convergence problem)?

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.

No picture, replaced lamp on HL-S6187W. TV makes a audio sound when I turn it on. Lamp does not light.


Did you replace the lamp? Was the Lamp original? Some time if you dont replace the lamp with original you are going to have this issue. Is there any sound. If you have sound and no picture is the Color Wheel.

Thank you,

I have a Samsung LN-T4065F--problems turning on


I read the suggestions regarding replacing four, slightly bulging 1000 microfarad capacitors. This solved the problem. When I removed the capacitors, I checked them with an ohmmeter and they were all showing low resistance (partly shorted). The suggestions in this blog saved me several hundred dollars and I am very grateful. I would not recommend Samsung again as I feel they are using inferior components. The TV is only two years old and I live in a temperate climate in the Pacific Northwest.

Dark picture on RCA Scenium 61 in DLP


Yes, the lamp will gradually get darker as it nears it's end. The rolling lines sounds more like the set is on a local channel for the cable hook up. If your local area has a channel 3 or 4 live terestrial broadcast simply tune the cable box output to the other one, the same for the tv.
If this is cable/local broadcast issue it will go away in Febuary when the NTSC broadcast ends.

I have a Hitachi 50v710


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!
