Hi! darrels,

This set has a convergence problem. Go to your TV set's menu, using the remote,
find convergence, following the directions on the screen; make the adjustments.

After turning the tv on the colors are reddish and slow to conform to the normal color tones. i have a 36" toshiba flat screen tv


My first concern would be that, the picture tube is going bad. The problem you describe, tell me one of the color guns is shorting. In this case I would think the green gun is shorting. There are three color guns in the neck of the picture tube. They are red, green, and blue. Most of the time the green will short as it is powered heavily in most TVs. The next thing to check, is the small board connected to the picture tube. Look for any and all bad grounds on this CRT board. This is another big problem in all Tube type TVs. On this small board there will be three color output transistors, and resistors. These will many times run very hot and will create bad grounds over time. Check and resolder as necessary. If the CRT board does not fix your problem, replace the TV. Picture tubes are very expensive and will not be feasible for replacement. Search for a new TV. Thanks for asking and show all hands of support!

My hitachi rear projection tv has one of it's colors out of alignment almost like it's been bent because it causes the blue color to be out of alignment in a curved fashion across the screen the tv worked...


All projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

I have an Hitachi 43FDX15B. The tv worked perfect


sounds like the convergence is out of whack. you will need to call a local repair shop and see if they can realign the color guns inside the unit. this is actually a really common problem with moving a rear projection screen.

Color is lighter in center of screen. It started as a small bat-man cape shaped area at top of screen and has moved down the center of the screen over the past week. About 5 inches in width and light blue...


sounds like the alignment in the color guns is off. this takes a professional to repair and usually isn't too terribly costly if it's just a realignment. check your local directory for large tv repair.

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.

Screen seems to flip


All the symptoms in your tv point to a convergence problem,the unit has 3 amplifiers one for each color,this amplifier IC's need to be replaced and then realign the colors,sometimes just by replacing the Ic's you are able to realign the color with the remote but sometimes they need to be realign from the service menu. You can identify the IC's because they are mounted in heatsinks and by its marking,in the front they have STK--- ---,6 numbers after the letters,their size is about 2.5 " long and 1.5" wide with a row of pins solder to the main board.If you are familiar with tv service this information will help but if you are not too familiar be safe and call for assistance from a servicer.

Conversion problem


Has it been moved latley? is there any auto align mode? i know the lenses can bounce inside there during a move and it can throw off the focus. If there is no kind of auto align it may need serviced. Usualy they have to come out and realign it using special tools. The tools display a cross on the screen in each color and they adjust the throw of the guns that refocus all the colors to the center till it becomes one solid color. The panel drops down from the fron and you adjust the pots with a plastic tool that realigns the guns. There may be a mode in the settings to display the image you use for the alignment. This is a common thing and i think they recomend it be setup at the home and not moved after its setup.
