Possibly not.. in this case with the 42HL167, the CPU pcb (most commonly referred to the SEINE PCB) is having issues booting and just isn't starting up.

My friend gave me his 42HL167 after this problem started after a power event during a storm and I managed to fix it by reloading the firmware.

I posted instructions on my website at:

http://www.benjammin.net/www/pages/techtips/Toshiba-Regza-42HL167.html

Once I figured out some of the facts, it was a breeze...

I posted this elsewhere here since there's so many duplicate threads... trying the firmware update is simple, so it's worth trying that first since the case doesn't need to be opened.

I have a toshiba 32 inch 1997 tv. When I turn32G90 it

It sounds like the picture tube may be weak (because it's orange) but it going to half ascreen is not caused by the picture tube but likely a vertical circuit problem. If this problem happened suddenly (going orange) then the picture tube is probably good and at least worth bringing in for an estimate.
