Lamp nearing end of life


Your best bet is to get a good TV Repair guy out to your house, that has the Sony Service Code Manual for your set. The TV Tech can access your Service Codes and clear that message out, and possibly make some adjustments that can eliminate the yellowish hue.

The yellowish hue could also come from smoking in the house or burning candles. I have 2 friends that still smoke and had the same problem with their Rear Projection Sony set. When the tech took their set apart he found the brown tar & the soot from the candles had covered the lens and much of the lamp area. They ended up getting a new set because of what it would have cost them to fix & clean the old one up.

There are at least 2 or 3 fans that pull air into every Rear Projection set. The air is pushed out the back of the set to keep it cool, so if they are sucking in dirty air, it will cover the electronics very quickly and greatly shorten the life of the set.

This is not as much of a problem for the newer "Flat Panel" (non-projection) sets because they usually do not need fans. They just let the heat rise throu the vents in the top of the cabinet.

I have the same problem and was told by a technician that I need to replace the light engine. Probably around $ 700.00.

I am told my Hitachi 61SDX01B (UltraVision/Ultrascan) has "Green Geometry"


Sounds like a convergence promblem.

Here are some of the most common symptoms of a convergence problem.

Screen looks 3D
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed in or warped.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence or magic focus section.

Try to adjust the 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.

Its a fairly easy fix on the Hitachi sets.

You can get a repair kit that includes all the parts from www.TvRepairKits.com. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself.
