  • jnsd Jul 25, 2008

    what is the part number and where can I get it?

  • 6slimshady9 Jul 29, 2008

    I have a Hitachi 46F510. When I turn the set on, the screen is blue and you can faintly see a picture, then it shuts itself off anywhere from 30 seconds to a minute after.



    I opened it up and turned it on and the green gun is not lit but the blue and red ones are.



    I have read the posts on here and haven't quite found the exact problem i am having.



    Do you have any suggestions?



    Thanks,

    Lee

    Hitachi are not known for bad CRT (tubes or Guns) it may quite possibly be the Green CRT drive board that is attached to the green gun, as usually if the green Gun is bad it will shutdown a hitachi. I believe the problem is within that drive circuit and they are very inexspensive boards to replace.

    As long as you get an honest one, as most may want to say the Tube is bad because they know its an exspensive part, alot of shops are not very honest sad to say. You may want to consider ordering the board and installing it your self as its very easy to replace depending on what a shop tells you for an estimate.

    I am not seeing a part number for it. But it should be stamped on the Board itself.

Have gone from a good picture to green and blue picture.what happened?


Hi:
If you are connecting the unit by componet cables (RED,GREEN<BLUE) check the cables first to make sure all are connected. If you find they are ok then your red tube may not be lighting up. If you are using a cable box try connectioning the set direct to the cable outlet on your wall. You could also be missing red drive signal to the CRT, in which case service is needed.

Green bulb-or lamp on ultravision hitachi 57uwx20b does not work how much to replace?


On a projection television you will have to replace all three(red,blue,green) projection guns in a matched set, the reason is if you replace just the green gun, your picture will be over saturated with green light making your picture look green,because the new gun will be alot brighter than the red and blue guns.
With that said, repair will cost approx.$400+, I've heard up to$600. Good luck !

If the lines are slightly curved and stationary on about 2/3 of the screen its either the Blue CRT or the Blue CRT drive board which is having the problem.

Color is bad especially colors like orange and the white on peoples teeth is black most of the time andthe picture is not clear


HI, thank you for visit fixya.
Common problem on this set .
Picture tube liquid is dirty.
Mostly in crt green and crt blue.
Do you have electronics skills?. If so, open the TV ( back cover), you will see green,blue and red gun. After turn on your tv, select any channel or video signal, cover with piece a paper two guns at the top ( any), and see how look the picture in the front, try one at time, ( press menu on remote control and see leters-clear). I am sure the green and blue will be no clear. all the time red tube is fine.
REPLACE COOLANT LIQUID PROJECTION ( solution).
I will be here for any quetions.
Thank you

No Red color at all. The convergence feature does not work either. Lots of green and blue RCA Model D52W59


Red color gun has failed, which will make the picture over saturated with the other two colors(blue,green) the bad news is the three color guns need to be replace in a set(all at the same time) because if you only replace the red it will over saturate the older blue, green guns then your picture will be mostly red.Unfortunently in most cases it's not worth the investment, better off to purchase a new tv. Good luck !

Ws-65611


you have convergence menus
Activate ……..MENU-2-1-5-9

Coarse Green Tilt
Coarse Red & Blue Tilt
the TV should have a Crosshatch or convergence signal

green done first to make it level
then blue and red to match the green

be carefull not to change any other setting other than the Tilt; because you can really mess up your convergence


if the menu adjustments dont do this for you:

you have a light box assembly inside the set that has the Red, Green and Blue Guns mounted on it: it can be mis alaigned as a whole causing what you are discribing. Also, you have a mirror that relects the guns onto the back of your screen: less likely but it could be misaligned..

Just be carefull not to touch any of the following:
wires, circuits, circuit boards, heat sinks, and especially the three Big wires that go to the 3 picture tubses... they have high voltage
the heat sinks could also be live .. Just be carefull !

make sure you have really good lighting and room to work and you should be able to fix this without a problem.

Sony Rear Projection TV - Red tube too strong


remove the front speaker assembly and the small access panel behind it and you will see a small square control assembly with 6 dials on it 3 control the color guns and 3 control the 3 gun focus. Try turning down the red control slightly they will be set up just like the CRTs red green and blue.

Green picture


you might wanna look into the "flicker issue" with your set...If you've had it for a while a could be that it's just worsened over time and developed into a voltage leak. I have the same set and it went undetected for a couple of years due to poor quality cable signal..once I went to a clear signal (ie. directv) the issue was very noticeable, but by that time it had progressed. Eventually one of your guns will fail and the set will stop working all together (mine did just under 4yrs from purchase) and unless you have Sears warranty that WILL try to stick it to you. TRUST ME!!! Good luck.
