I've had my Toshiba for 5 years & have had no issues until this week. We heard a pop & the TV turned off. When we turned it back on, the color was completely off -- very green & lacking any red. Adjusting the tint & color has not resolved the problem, which makes me think that our red "tube" (for lack of a better word) went out.
Has anyone had this problem? Does anyone know if there is a replacement part I can purchase & install or is taking the TV to a pro. the only way to remedy this problem?

Toshibas are notorious for developing shorts in the inernal guns of the picture tube. In your case the green gun is shorted to G1. The noise you heard was an internal arc between the elements.
It is unfortunate however, the repair of this problem usually requires the picture tube to be replaced. Sometimes a savvy technician with sencore picture tube rejuvenator can remove the short. This however usually does not last. Scrivitron

I seemingly had the same problem, it just wouldn't turn on the tv or do anything for that matter so I popped the controller open to have a look and noticed that there was a small square box capacitor where the "cheap" metal that was making contacts with the circuit board had broken so I re-soldered the broken pieces and voila it worked. Cheers I hoped this helps some of you that have this same problem.
The symptoms you describe is the main processor controller is about to fail, when that happens the tv will eventually become unuseable. if the set is more than 5 to 10 years old you will be further ahead to replace the set.
More than likely, as with almost EVERY 46HM95, it's your light engine or color wheel (same thing) starting to go out. The piece alone will run between $500 and $750.. Install prices depend on where ya go. And don't let the Toshiba rep lie to ya. That person might not have known the problem, but Toshiba as a whole has heard about this problem and known about it. If you've searched the internet for the same problem, you'll see that almost everyone that has bought this TV gets the same response from Toshiba "Never heard of it" or "it's out of warranty, tough luck" I'm surprised there hasn't been a class action lawsuit yet.
Plug your VCR into the back of the TV, using the "VIDEO 1" input. (Yellow - Video, White - left sound, Red - Right sound). Press the "Ant/Video" button on the front of the TV until Video 1 is selected.
* The TV set may be unplugged.
* A fuse or circuit breaker may be blown or switched off.
* The remote control unit (RCU) may be disabled.
* Make sure the TV/VCR are plugged in and the wall switch is on.
* Check the fuse or circuit breaker. Test the outlet with a lamp.
* Replace the RCU's batteries: if this fails exchange the unit.
