Question about Mitsubishi WS48511 48" Rear Projection Television

1 Answer

Blue color cannot be adjusted

I read what you put up concerning how to buy a convergence ic to fix the problem with the blue ghosting and how it wasn't allowing the user to adjust it anymore but does that part also control the yellow and green etc?

There are two ics trhat control the three colors alignments. Its always recomended to replace both Convergence ICs at the same time when doing the repair as they both share the green color between the two ICs.

Color convergence problem


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.

Sony KP-46WT510 convergence IC's and checking resistors



You have a convergence problem. Here are some of the most common symptoms.
 
Screen looks 3D
One or more colors can't be adjusted when using the convergence menu. 
Screen is bowed in but stationary.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem. 

>>>Solution<<<< 

You need to replace the convergence chips and convergence resistors. 

Check the site www.TvRepairKits.com. They have put together a kit for your exact model. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself.

The green and blue ghosting is a convergence problem that is either bad connections at the convergence ICs or defective ICs. If you can solder, try resoldering the ICs. If that fails to resolve the problem, replace them. These ICs are large black ICs attached to a heatsink. They should be marked STKxxx.
Keep us posted.

Misaligned Convergence


Is anenvolved job to repair a convergence problem,the way to go about it is to locate the convergence amplifier IC's,one for each color(red green,blue)check for loose conections at the ic's legs,after resoldering all the legs see if an improvement is present if it gets better you will be able to adjust from the custumer controls,but if no improvement the Ic's will have to be replaced.Some units have a separete board were you can adjust convergence after replacing the Ic's and other units you have to access the service menu to be able to do the adjustments but just doing this adjustments can be very challeging even for a train technician,I would suggest you seek assistance from a servicer and get an estimate.
