Mitsubishi WS-48511: can't adjust blue convergence

Sounds like a convergence problem. See if you can adjust the customer convergence controls (in the menu).
If you can not adjust one or both the colors than your convergence amp is toast!

No,need to diagnose.It a 100% convergence problems.Convergence problems very easy diagnose.The picture look like 3D,colors lines don't lines up.Fuzzy,out of focus.Convergence controls don't work to lines up any colors cross.The tech is cheating u if he said cost $125 to diagnose.If u know how to solders u could fix this convergence problems about $100.U can buy a convergence kit at Websites Tv repair World.com,Tvrepairkits.com.The shop everythings fix parts and labors only $300.

Adjust the cross hairs on your TV. See menu setting for convergence. If this will not cure the problem..you have a bad convergence board!

U can't,it ur convergence it dead, must replaced parts.U know how to solders?Tries these websites Ebay.com,Tv repair kits for convergence board or parts.

The PT53WX53 convergence repair kit available at www.tvrepairworld.com should repair that issue. The repair kit contains the parts and the CD with instructions.

you need the convergence IC's replaced.

This is a V-21 Chassis common, with these symptoms, for failure of the convergence amps. This set uses two STK 392-110 Sanyo amps mounted on a heat sink and hard to miss. They're a 40 pin ic about the size of a half pack of cigarettes.
It has also been my experience that two or more of the yoke return resistors need to be replaced, most commonly R8c21 and R8c22, both are 3.9 ohm 1w but test all of them for reliability.
Hope this helps!
