You have bad convergence IC,I'm afraid. You will need to have both of them replaced. this job should run you about 300 bucks or so to have them replaced and the set realigned. DO NOT try to adjust the convergence inside of the set before replacing the IC's, as this will only make the job cost you more. Good Luck

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 !

I have a sony 50 in rear projection. 9 years old


Sounds like the CRT tubes are going out which is fairly common on Sony. Inside the back of the TV there are 6 knobs - 2 for each color...one is for focus - dont touch - the other for brightness...turn down the brightness just a hair untill the lines go away.

The color is screwed up


The projection TV has 3 color guns that focus to produce a single image. The 3 colors are red, green and blue. It sounds like the blue gun went out. You should be able to remove the back panel of the TV. If doing so, use caution as there is a mirror attached to the back panel. Once removed, you can confirm that the gun is not working. The fix, unfortunately is neither easy nor inexpensive. The problem could be simply a poor connection to the circuit board up to needing the replacement of a new light or perhaps a new gun. Unfortunately, there is no magic button to press and nothing you are doing wrong. This is a very nice TV and it may be worth getting an estimate to repair it. Or, perhaps this is a good excuse to go out and get a new 50" plasma! Hope this helps. If you can think of anything else I should know, please comment.

Yellow and blue color ruins total picture on 50" tv,can't get rid


lupe0112,

I'm no expert, but I think that you have a problem with the convergence of the 3 color guns. I've been working on a similar problem. As a first step, have you tried "Magic Focus?" The Magic Focus button for the Hitachi 53UDX10B is at the left of the small front panel controls that also include your RCA composite and SVideo connectors. Let the set warm up for about 20 minutes (as recommended by the user guide), and then press the Magic Focus button. When you press the Magic focus button, the set will auto align the 3 color guns. If this doesn't fix your problem, unplug the TV for at least 4 hours and try again.

Projection TV red is drooping


Do an internet search on "Hitachi Convergence Circuit". This apparently happens all the time. TV repairmen charge about $400. Parts are less than $50 but you would have to be an expert at soldering electronics circuits to replace it yourself.

My TV had the Blue misalign instead of the Red. I ordered the kit #9 from http://www.bdent.com/search/part.jsp?partnum=KIT9

DO NOT ATTEMPT IF YOU DO NOT KNOW HOW TO SOLDER. YOU WILL PROBABLY RUIN YOUR TV.

Blue Projection Gun


It is not the gun ,but the convergence IC that needs replaced providing that you have went into the tv menu and selected convergence and manually adjusted the blue convergence.

The alignment you need to do to realign your TV is called "setting the convergence". All projection TV's have 3 color guns (one red, one blue and one green). When you move a TV or josstle it, these guns can get misaligned and need realignment. This is definitely something an average user can do (you don't need a TV repair man to do it for you). It is a very simple procedure (most TV's have an option in the menu to do this, just look for convergence adjustment). What you want to do is use the remote to get all 3 colors to overlap completely (you can only move one color at a time). Some TV's have squares on the screen that you must align, others have plus signs. If you can't find it in the menu on your TV or if you can't figure it out on your own, you can look for a manual at Hitachi's website that will walk you throught the process for your TV.
