Blue outlines on screen. not a screen burn or convergence problem


I am not familiar with that particular model but most are similar.
It may need the blue focus adjusted. Most tv's have some type of automatic focus. If the blue is out of focus it can "bloom" beyond the red and green. There should be a focus block with 6 adjustments (2 rows of 3) behind the speaker cover. I wouldn't mess with the one labeled screen or block. Adjust very carefully. They are usually in the order Red-Green-Blue with the focus on the bottom row.

Toshiba 53h71 Blue Shadow/Shade problem


If the shadow is off to one side then it's a convergence adjustment. If it is a blue outline it may be your blue focus. There should be focus knobs behind the speaker cover. They are usually covered by a piece of black tape. The convergence screen should have a prompt for changing the color you are controlling, possibly exit button. Toshiba has several of the older owner manuals on their site as archived models.

Red outlines in the picture


somewhere in the tv menu there is a place to make video adjustments. one should be for aligning the color guns. one is for red and the other two are green and blue. it will give you a cross in the center of the screen. it should also give you prompts to adjust the lines for centering and to save changes. this happens eventually on all rear projection tv sets.

RCA D52W20 will not keep blue in focus


If i understand your problem...blue is out of focus.. does the blue ever in focus?...i just fixed one today at the shop with a simular problem.. is red or green sharp. do u see the blue in the outline of text on screen is the blue only in one area of the screen. it could be as simple as convergence or like the one i delt with a blue tube was leaking fluid. The leaking fluid would be bad thing,. the convergence not so bad and not as expensive. so give us a complete description and will see ehat w can do..

Red duplicate image outline of picture.


you have lost red convergence. which ussally means one or both of the convergence amps need to be replace.. but it could be a resistor. does the red cross move up or down or side to side. how about the blue does it move in eather direction. this will let me know if both are bad

Convergence not lining up


Sounds like the green is out of focus. If the focus control for the green does not control it enough to make the width the same as the red, then, the lens on top of the green can be adjusted to focus that tube. On the lens, there is a wing nut on a screw to loosen it and move the lens left or right a bit to help with the focus. Hope this helps.
