On left half of the screen [ KP51WS510 ], a redish shadow showing

Check the cables in and out of the TCon board replace the Tcon board if that doesn't help

These sets have several common problems listed below.

Problem #1) Convergence

Symptoms:

• Screen Looks Distorted/3D
• Colors wont align
• Screen may look distorted
• No Audio/Video - makes a chirping sound.

Problem #2 CRT Fluid has clouded over. Symtoms

• Dull looking screen
• White looking sceen
• Halos around objects
• Red/Orange looking

I had similar symptoms about a year ago. Also came on sudden. The red convergence chip had burned out (poor heat sinking on this model Hitachi). Replacing the color convergence chips fixed it. ($50 for parts.) First, however, have you tried the "magic focus" function? That's explained in the manual, which is available online IIRC, but I'd have to look for the link if you need it.

This set needs a fluid change. Between the face of the picture tubes and projection lens there is a layer of coolant fluid. The fluid has turned a milky brown color and is degrading the picture. The tubes have to be removed in order to do this properly. I would suggest you contact a repair shop and have them check it out for you as this can be very complicated. Thanks for using fixya and I hope this helps you out.

Problem #1 - CONVERGENCE PROBLEM

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.
• TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Here are some photos of convergence problems.






Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

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

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

CONVERGENCE SOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

replace STKS on convergence board

sounds as if your convergence needs to be set. either through the menu on the tv or remote you need to get to the convergence set screen and you need to line up the crosshairs. this usually happens when the tv is moved or bumped.

Blue convergence IC bad...have both IC's changed..insist on
STK394-160E upgrade part # CZ 01341 Hitachi brand.....Original part is STK392-110......Also, check B+ feed resistors next to
convergence amp IC's for burn / damage...after rebuild, press magic focus.......................T.

This sounds like a convergence problem. This is a common problem that is usually fixed 98% of the time by re-placing the STK392-020 ic or STK392-110, and check the fuse devices on the covergence PCB. I'm sure the actual parts numbers depend on the peticular brand. Good Luck!
