When it does this go with the Mitsubishi remote to the menu--look for convergence-then advanced= you should get a grid of yellow lines and if see red ones not lined up the set uses one or two convergence chips ( I can look for you).

It is very common for the chip/s to act up when cold or after warmup--convergence will seem to jump in and out when that happens---in 100% of the cases I have seen (about 500) replacing the chip/s cures this and for most models I have the instructions for this repair of my own from having repaired hundreds of these sets.

SOURCE: problem with color

Yes you have a problem in the red crt driver board. Most likely the driver transistor is failing. This is a component level repair, so if you have no experience with TV repair, play it safe and call in a trained tech to assist you in this matter. Good Luck

SOURCE: my mitsu WS55819 looks fine

Hi,

Hello, friend you have a convergence issue, first see if they will move manually in your menu, they should be able to move up down left and right, and if not this is when two chips labeled STK392-xxx Failed. They can be located by finding the largest heat sinks in the unit.

Along with the possibility being an open resistor and or open fuse in the convergence circuit. All of the resistors around these chips should be checked pay attention to the ones that are standing up and they all should read low ohms, If they are in the k ohms they are probably open which is bad ,This is a tricky repair, if you have Never done this repair I don't suggest it friend.

But if you are willing to tackle this problem the only step by step procedure I found for you would be to watch someone do the repair, and this I found on the internet in the convergence problem screen. This will give you an idea of the work involved and also what the parts look like.

Hi,if its a an LCD RPTV it sounds like a light engine problem.Basically your tv uses 3 LCD chips that create the image .Each chip is like a tiny screen that blend together to get the colors and picture right.They are green,red and blue.When they start to fail you will start to get color discoloration or vertical lines.You will need to replace the light engine.God bless you!

3. Turn the blue screen control on the Focus Block until retrace lines appear and gradually turn it back
until the point where you can see the retrace line disappears, just before cutoff.
4. If the screen still appears too bright after proper G-2 adjustment, you need to adjust the sub-bright adjustment in the service menu
control down until screen cut-off. (Service data Range is usually 21 to 25 in the Service menu, for Sony sets you first go to category "MCP2", & then adjustment item 01( "SBRT")= subright.
For electrical the focus, put on the screen a clear picture of your choice thru an input of the TV set from a DVD, then pause the playback of the DVD Look into each color and rock that color focus control back and forth (turn the control one way then the other way slowing down as the picture goes into the best focus. till the picture looks sharp do each color till they all look in focus. NOTE: it is best to look into each color tube to achieve the best electrical focus. For optical focus please follow the manual lens adjustment in the sets service manual

Color problem after warm up.


The probelm is caused by either a bad color wheel sensor, color wheel or formatter board. I have the new redesigned sensor assembly and color wheels that I can sell. It is best if you send me the projector for proper diagnosis.
