Thanks for the help. Particularly the tip with the full field vs. windowed IRE pattern. I will make sure I place the cell the same way each time. Since my set it a 16:9 and the cells usually are quite rectangle, I will align them within the 16:9 raster area on each tube. I will have to make my own lens cap as I have a RPTV.
So, I think I have enough info to give it a try now. I WILL make sure I have someone with me before I open up the set.
My next step is to start purchasing the supplies for this project. It looks like a good 6500K high CRI tube will be the hardest. I checked out Timâ€™s link (which is for the Lumichrome 1CX 5000K/96CRI tube) and found the 1XX tube http://www.truesun.com/lumichrome1xx.htm
on the same site. The 1XX is a 6500K/98 CRI tube (which I think you have mentioned in one of your previous post Guy). The info on the main lumicrome 1XX/1CX truesun.com pages make it look like you have to purchase them in a minimum of a 25 pack, but if you go to the order page, it looks like you can purchase them in a minimum quantity of between 2 and 4 (depending upon the size of the tube).
For example, the FW151XX (T8 18â€ 15 Watt 790 Lumens), which I think I will buy, is listed at a minimum of 4 at $14.95 each. More than I want, but less than 10 or 25 at $14.95 each.
I plan on documenting the entire process and posting it (with photos) on my web site. Once done (At the least a few weeks), I will post a message on this forum to let you guys know how it worked out.
