Toshiba TP50G50 Theaterview picture is double with red color only

Sometimes when the TV is on the screen with appear but with a double picture. Only the red color seems to duplicate. Previously when the power was turned off and then back on the screen would correct itself. Now there is little or no change in the picture when the power is turned off and back on. We love our TV but want to fix the picture problem. Does anyone have a fix?

Your alignment is off. Go to the set up menu then convergence. hit right and you will be in the convergence menu. select the color that is not in alignment. The green line does not move. if blue and green are lined up the line will be cyan. if red and green are lined up the line will be yellow. when all three are lined up the color will be light. Best of luck!

Have an older Toshiba theaterview TV, when turn on, we have no picture, no sound, just black screen and blinking red light that just continuously blinks.


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.

Fuzzy picture help 55" rear projection toshiba


Just click below for convergence repair kit;

http://servicemanuals.vstore.ca/

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.

Objects are doubled and colors are distorted


Projection sets have two very common problems.

The first common problem is convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

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

Have a Toshiba TP50G50 Projection televison with no picture. Have 100 volts to power board


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.
