BTW, before any of you guys start snickering at my old and trusty rear projection CRT monster

, I will say the following...
I recently unhinged the screen on my 58" Hitachi Ultravision TV and vacuumed the dust out of the unit. I then proceeded to polish the three colored light guns and then used a rustoleum black and painted over any possible reflection points such as metal chassis or screws or even light particle board.
I put it back together again and ran a digital convergence on the TV from a downloaded service manual.
I fired this beast back up and OMG!! What a nice picture!! While not quite up to the top of the line plasmas, this TV sure holds its own.

I've got it totally encased in a wall unit so that only the screen shows.
OK, back to the original subject of this thread....
Regards,
Randy
