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)?

Download this manual
http://merchant.satisfusion.com/sf/library/manuals/owners/50V720.pdf
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.

Replaced the balast, tv not longer turns on and off but now it has a kind of pulsing picture. Am I looking at a new bulb? a new color wheel ? or some other surprise that I haven't heard about?


Lamp is possible especially if the ballast was bad--it powers the lamp.
Color wheel will usually display some issues--high pitched whine or fan like noise---with the lamp removed look where it faces--color wheel is there--any broken or missing pieces and it is the problem---

The wheel is directly connected to the set---set will detect if wheel not moving or moving too slow etc and almost instantly turn the lamp OFF.

My almost 10 yr old Mitsubishi HDTV intermitently has color flux


The Main issues with the Mitsubishi HDTVs that size are the projection bulbs in the rear. A large TV like the Mitsubishi can allow dust build up on the lamps and the mirror in the rear that projects the picture to the screen. An easy fix would be to clean off the dust off of the mirror and bulbs. You would need to go through a tough processto do this since the mirror can be quite heavy and is in an ackward place. The only other alternative would be the need to replace the projection lamps themselves which can cost any where fromm $150 - in some cases $300 a piece for the lamp itself. The Television is still a great set but can cost quite a bit right now to fix if the problem is with the Lamps. If you can afford the Lamp replacement if it is needed the set would last you another 10 years plus. If you wouldn't like to go through the hassle of repairing the set or finding a place to repair the set there are so many new sets out in the market that will give you an amazing picture and quality.

WD-62525 My tv wont work. new lamp does not work. have tried ever


I had the same problem with my 52". I had the error code of 34(lamp abnormal). I put a lamp in that I knew was good and changed the ballast with one that I knew was good and had 8 caps replaced on the power board(they where not puffed but did them anyways) and still nothing. light came on for 3 seconds and went off again and tv shut down with a red status light. I did some reading on other web sites and found that if the color wheel is bad the tv will not work. I found a light engine on ebay for a 100 bucks used and installed that and now it works perfect.

Lose picture 10-25 sec., keeps soud


I had the same problem with my set. the problem was with the lamp bulb. They don't teel you this, but when a bulb start to go, this can happen. Iuld turn my set on and it would work. After about 45 seconds, the picture would "turn off" (still have the sound). This would last for about 45 - 60 seconds and then the picture woudl come back, but then the cycle would stsart all over again. I took a chance and purchased a new bulb (I bought just the bulb, not the bulb and housing). I took out the current bulb and housing, replaced the bulb in the current housing, and put the bulb/house back in. Problem solved! (have not had the issue since). Hope this is helpful!

DLP TV starts to loose picture after 1 - 1/2 hours of use


This tv has a 3 board video path. Analog main pcb --->Digital main pcb --->DMD pcb. see which inputs have the problem to narrow it down. if only some inputs, suspect analog board. if everything flickers(all inputs and menu), suspect the dmd or engine. you can see the lamp shine out the back. if the lamp is flickering, suspect lamp or ballast.

Samsung hln5065 picture issue


If all 3 lights are blinking on Samsung DLP it means your lamp is burnt out or has issues. The manual says replace the lamp when all 3 lights are blinking. If you can hear the arc from the ballast the lamp should light if the lamp is operational.A new lamp should solve your problem.

Power issues (Tv not turning on) were typically due to faulty ballast. While the TV reports a bad lamp it is the ballast itself causing the issue. Samsung is well aware and will replace both the ballast and the lamp (since the lamp can be prematurely aged but the bad ballast). After replacment most people stop having issues.

Dwin lamp turns off


I design and implement switching power supplies for the commercial lighting industry. I also own a DWiN Transvision and have opened it and worked on it several times. I believe I can answer this question.

The DWIN projectors use a proprietary switching power supply to strike the lamp and keep it burning. The power supply is extremely sophisticated and maintains tight voltage and current tolerances. This is important because the halides in the lamp are damaged by power supply fluctuations. The halides can often be seen in an unfired lamp, they appear as small specks of dirt or tiny beads inside the lamp envelope. When a metal halide lamp is struck, the halides (which are rare earth elements) vaporize and cling to the inner wall of the lamp envelope. The mixture of halide gas in the lamp is what determines the color temperature of the lamp, as well as the accuracy of the lamp across the entire color spectrum.

One of the ways that DWIN is able to deliver such great color is because they use a lamp which delivers this great color across the spectrum, but, as I pointed out earlier, can be damaged by fluctuations.

The power supply contains three switching sections and five references for such things as input and output voltage for each psu section, as well as overcurrent demands from the lamp.

From my experience, your lamp(s) are all exhibiting issues that require replacement.
