Question about Hitachi 70VS810 70" Rear Projection HDTV
I was told that it could be the color wheel or the light engine. Is there any other possible cause? I removed the rear panel but am unable to determine the source of the rattling.

Could be the blue CRT shorting out. I had the same problem but with red. Eventually it shorted out completely. If it is only 2.5 month old it should still be under warranty and they will fix it.

If you are not experiencing any shift in colors, it sounds like the power supply is failing since this will affect all three colors.

Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.
Here are some of the most common symptoms and example photos of a convergence problem
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.
You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.
