Tim,
Gee I'm pretty good with electronics and I've never heard that joke!
What you have there is a convergence problem. Your unit takes two STK392-110 Ic's at position numbers IK04 and IK05 respectively. Also check and replace as necessary Rk50 (2.7ohm /1w), Rk62 (2.2ohm /1w), Rk63 (150ohm /2w), Rk46 (1.8ohm /1w), Rk42 (3.3ohm /1w) And Rk43 (220 ohm 2w). In fact test all of the 2.2ohm resistors in the yoke return just out in front of the amps for change in value.
Also make sure to use Sanyo original Ics and not some asian knock-offs which are readily out there.. Get them from Acme in Florida http://www.acme-sales.net/index.shtml and rest assured you're getting Sanyo originals..

Color shadowing on screen


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.

Projection TV sets have two very common problems listed below.

Problem #1) Convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

(Hitachi 43F300) Turning its self off


Sounds like it is going into shutdown mode. When the TV power supply and system control sense an overload the system control turns the TV off to prevent further damage from happening. I suspect it is a shorted convergence IC. It would be best to call a service center to repair the TV.
