The 'white spot' problem on the Toshiba 65HM167 TV is caused by a faulty optical block processor or 'light engine' in the TV. It must be replaced for the problem to go away.
The bad news is that the optical block processor is expensive and, since DLP TV's aren't manufactured anymore, they are somehwat hard to find. I found one at www.encompassparts.com for $647 of which $220 is a core charge that is refunded when you return the old light engine back to Encompass Parts. So the out of pocket is around $430 with shipping. The Toshiba part number for the light engine is 75006693. Encompass was very easy to work with.
The good news is that you can make the installation yourself. It's a little complicated but with patience and a careful labeling of all wiring, you can make the switch. I did it and my TV now works better than ever (no spots and a much better picture). Get a service manual for the Toshiba 65HM167 at www.servicemanuals.net for $17 (download) and it will give step by step instructions for replacing the light engine. The replacement process took me about 2.5 hours.
Is it worth it? I think so because I love the size of this TV and to replace it with a comparable LCD TV would cost around $2500. Of course, I won't know for a while because if this new light engine fails anytime soon it won't be. Since I bought my DLP TV early on in the product cycle, I'm betting that the replacement is better technology. We'll see.
