Hi,
If this tv is more than 10 years old, I would say the three projection tubes are getting weak.
This may be a good time to invest in a new tv.
considering the difficulty of obtaining parts for it and the other problems you could have in the near future, it would be cheaper to replace the tv.
If the tv is not that old, please let me know the model number for more assistance.

I am trying to adjust the brightness on this circa 1980 floor model solid state tv


The contrast setting controls the relation between the light and black areas of the screen. If the light areas are too bright and are losing details, press the CVOL button; if the picture is gray and lacks contrast, press the VOLB button

The brightness setting controls the overall amount of light in the picture. If the picture is too bright, press the CVOL button; if the picture is too dark, press the VOL B button

The color setting controls the intensity of color.

Red & green shadowing on the right side of picture


tried to adjust the convergence settings in the menu in the color adjustment in the tv menu. if can not adjust, you have bad either an open resistor or bad ic in the convergence circuit which control the color adjustment.

Shadowing of picture


A shadowy or 3D image is caused by the convergence not being aligned. If your model has a convergence menu goto it and see if you can adjust the colors so that they are all straight and aligned. If so the 3d shadows will go away. If however it wont adjust the convergence has failed and would need to be to repair the TV yourself or with a company. Convergence repairs are common a fairly easy DIY fix.

My picture in my television is like shadow box size but not a normal shadow box program. When the t.v. is bumped the picture goes to normal then back to small , What is obviously loose?


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
•Screen looks 3D
•Colors don't line up
•One or more colors can't be adjusted when using the convergence menu.
•Screen is bowed or warped.
•TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Here are some photos of convergence problems
