Question about Hitachi 51F510 51" Rear Projection HDTV-Ready Television
I guess from reading the manual that the TV has three "tubes", one red, one blue, and one green. I think I lost the green tube. The color is all pinks and blues, really looks like ****, sometimes it goes back to normal for a few minutes, then changes again, is this a reasonably inexpensive fix or should I just trash the TV?
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

I'm trying to fix the issue on my 43FDX20B. So far, I'm able to move the lines up and down, but can't get the left/right motion to fix it. The attached link has the dynamic mode instructions, so you can correct this issue yourself.
The only thing I didn't have was the screen overlay jig the manual talks about. I decided to create one myself and use the screen as a beginning template. I went to our local hardware store and picked up some home window weather covering. The roll cost about $15, is a clear strong plastic and the template was very easy to create. I used a straight edge after I put dots on the plastic and measured the lines for being square and equal after I took it off my tv. Good thing is that if you don't like what you make the first time, you have a 25' roll to use to try again (ha).

It sounds like your convergence ic's are messing up
They have a kit for this tv it is available through local parts distributors
If you can't find it locally just Google HITACHI CONVERGENCE KIT
If you are not good with de-soldering and soldering do not attempt this repair. Remember to replace all the resistors in the kit
If you are not sure about doing this repair you should have your local tv guy do it for you

If the convergence is off more than 1/2 inch or so you can't adjust. you have a failure of hardware. most likely the output IC. This set has 2 outputs for convergence. Each output contains 3 circuits, Six circuits altogether 2 red ,2 blue and 2 green. The normal customer adjustment will only alow adjustment of blue and red. They should be converged onto the green. There is a much more complex adjustment in the service mode for Geometry and convergence. These adjustments are only needed when you replace a failed componnent like the output ic. These ICs have been upgraded several times since the production of this set. The latest and most powerfull version is STK394-160. If feel up to it I suggest changing both outputs and the corresponding output resistors. Then do a complete geometry and convergence alignment.

It is a convergence problem and set uses two of the STK-392-150 CHIPS. Both will have to be replaced and the set adjusted.
for more information let me know if you can solder and your skill levels.

You have Light Engine Failure. Only fix is replace the Engine. Here is a Page that shows Hitachi LCD Projection TV Optical Engine Faults.
Check for these faults before spending money on a failed bulb. Here is page with all Hitachi TV Lamps and Bulbs.
