Question about Mitsubishi WS48511 48" Rear Projection Television

1 Answer

Color convergence problem

Have a Mitsubishi rear projection tv, model # WS48511, that has a yellow half moon image at the top of the screen and has blue ghosting on picture and text. I have tried to adjust the convergence settings, the blue, green and red, and found the blue color, when in fine mode of adjustment, has the half moon image and unadjustable. I have reviewed postings on this site regarding color convergence problems and have found replacment of the convergence IC, STK392-110, would solve the problem. I would like a conformation or diagnosis procedure on the problem before purchasing.
Thanks,

Ed Rizzo

If you follow the instructions on the other thread, you should be able to resolve the problem. Try the simple stuff first. Resolder the pins of the convergence ICs and see if that alone resolves the problem. Sometimes that is all it takes.

Keep us posted.

The Color On My Mitsubishi Rear Projection Tv model- WS-55908 looks to be off, picture looks blue and Yellow.


its sounds like the convergence on your TV needs to be adjusted. (this adjusts all of the color guns in the back of the tv to line them up again, when they get off, you start to get yellow blue or red halos around objects in the picture. In the setup menu on your TV under picture or Display there will be an item that says "convergence" follow the instructions in there so all the crosses on the screen no longer have colored halos anymore.

The top half of the screen is scrambling with wavy lines. Can this problem be fixed?


If you go into the customer menu and select convergence--instructions will appear on screen--select advanced and a grid of lines will appear.

If red or blue are skewed and will not adjust you have a convergence problem-If model ws48511 I have complete do it yourself instructions for this kind of fix.

YOU can post a photo here of what the picture looks like--I will attach one of a typical convergence problem--no two look the same but you will know if this is the problem you have.

My rear projection Mitsubishi TV all of the sudden


No, this is a convergence circuit problem. The cost of this repair is about $450. This is something that you can't do on your own. Call an Authorised Service Dealer and get estimate or buy new one . If you buy a new TV buy an extended WARRANTY because they are not as reliable as the OLD TV's.

Good Luck, Big Irish.

You have 2 IC's in the convergence circuit and possibly a micro fuse that needs to be replaced. Consult a local TV repair shop.

First of all check the circuit boards to see if ant CRT coolant has bee leaking on them. A strong flashlight will work best to spot it. It will usually appear on the front half of the boards nearest to the screen,. Mitsubishi has had some issue with CRT leakage. Also check for solder cracks around the Convergence amp ICs. Let me know what you discover, or if you need anything more.
