Check the power connections, Check the power light. If there is no light probably power supply unit might have failure. Usually over current causes break of the fuse on power circuit. Power circuit issues usually cost low to repair. Its good to have a qualified hands on technician's assistance to diagnose power circuit.
You can contact Toshiba hotline as well (800) 631-3811

Good Luck

Something is preventing the power supply from operating:
Possible causes in order of likelihood:
1) Convergence amps failed overloading the supply (See if you can disconnect them)
2) High Voltage circuit has died. (Right on schedule since your TV is 10 years old)
3) One of the CRTs has shorted
4) The power supply itself has died (Is there a lot of dust covering it?)
See if you can isolate the failure by working down the list.
Hope Ya Fix 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.

Sounds as though you have a filter capacitor bad in the power supply. I strongly suggest you have it checked and repaired soon, before it burns up a transistor or regulator. The cost may be a bit high now, but will escalate to possibly a complete power supply board. If you can repair your own set, check the main power supply filter capacitors. Good luck. I hope this has helped.

Need to test F470 and F850 for open.. Simple continuity to see if either fuse is open.. If F 470 is open replace it and C884 and if F850 is open you probably you may need to replace the two convergence amps STK392-110... Large black Ic's screwed on an aluminum heat sink...
