I havenít got a clue what to advise concerning your TV, but want to thank you and your comrades in the RAF for your valor and support of our US troops. Good luck and God bless.
RE the red TV: Perhaps you would be better served by a new television purchased from a local source. Keep your Toshiba in storage until you are restationed at a location compatible with its temperment. Hopefully it has not been "repaired" beyond recovery. I didn't even know you could re-gas a tube.
