Greetings,

Power supply cannot sustain / provide juice to the whole system.
If you are qualified to do electronics, check the power supply section, otherwise contact a repairman.

Keep us posted and thank you for using our service.
FixYa for all your troubleshooting needs.

It could be the lamp went out and needs replacement. The Toshiba website states when this happens to unplug the televison for 10 minutes then plug back in. If that does not work then try another power outlet. If that does not work then call for service

Try disconnecting all the cables from the TV then reconnect them after a few minutes. It's suggested that you connect the power cable from the TV directly to a functional wall outlet.

If still there is no picture on the TV then it's required to replace the projection lamp.

The sound amplifier IC has went bad and needs replaced. Call a good TV Tech.
Check with the BBB 1st before you decide on one.

Normal color picture is composed with 3 colors R-G-B (Red-Green-Blue). Picture turns Red means: Missing Green and Blue colors (many reasons: bad contacts, projector tubes dead, and other...). Try to give some "tabs" to diagnose ... I don't know what is the type of your Projection TV, how long you owned it, to have more idea.

I have the same problem - just happened last night. I found this posted on this sight. Does your problem sound the same?

Check all fuses in the power supply and look for any bad connrctions on the PCB. You are probably missing the 130 volt supply to the horizontal circuit. Common reasons are: Shorted horiz output transistor; flyback transformer, picture tube arcing , bad power regulator IC. In short, you need to get a qualified tech for this symptom. Hope this helps.
