Toshiba TP50G50 Theaterview picture is double with red color only

Red means TV on standby. TV remote not working. Check the transmitter LED flashes by viewing remote on a digital camera or phone whilst pressing the buttons. The invisible light will flash purple viewed from the camera.

Theaterview suggests a rear projection--in that case it most likely is in the convergence circuit--unsolder chips (convergence) and see if set turns on.

Some of their regular TV sets (picture tube) if the light is just blinking means the same thing=shutdown because of a short/problem but a model number would tell me which you have.

isit a large rear projector ??????? if so the colour guns need adjustment

Just click below for convergence repair kit;

Double images and colors are blurry .Blue,red and yellow wave coming up from the bottom of the screen on the lower left and fuzzy images this is a symptom is for busted convergence IC,you must replaced this IC in order that will works better again.STK 392-xxx ICs and it's associated resistor,this resistor automatically change value,can caused trouble even though you change the ICs.If you bring this to a service center they cost you $600 to $700,but if you buy the repair kit you can save more,don't wory it is very easy because there is installation guide including in the repair kit. Feel free to ask whatever the result... click the link for sample picture guide step by step installation;

convergence amps bad, also check resisters burnt

Your set has 3 screens:
FA812 SuperShield is no longer available
23837472 Lenticular lens is no longer available
23837450 Fresnal lens is also not available.

Check with some of your local TV shops. You may find a non-working TV with good screens for sale.

Good luck

100 volts is too low to power the entire projection TV. Usually with rear projection TVs there are three tubes that create your picture on the screen. To power those tubes, they each require a high voltage (usually around 10,000 volts - yes ten thousand) that is produced by a high-voltage step-up transformer call a 'Tripler' - since it powers all three tubes. This device and the rest of the TV require full utility voltage (120 - 130 volts AC) to properly power the unit. Correct the voltage and try again - is the house / residence voltage like that in each room? IF so, you probably have other issues with devices you probably haven't picked up on.
