This is a convergence issue. Go to the menu and look for convergence.

What are signs of picture tube going?


Signs of a CRT going old, are bad focussing, unnatural colours and hues of a certain colour (red, green, or blue) if you watch black/white pictures. In colour pictures, black sequences also show hue.

Both the picture and sound work when the TV is turned on, yet the picture is distorted like a double picture and has a yellow hue to it.


Sounds like you have a convergence problem. If you go into the setup menu of your TV, there should be some settings to adjust the red, green and blue hues and re-position them so each color matches up. If this does not work or if you don't have a menu, your TV *might* have a circuit board with several plastic screws on it. These adjust the picture and it's a very tedious task to re-align each hue correctly.

My projection TV is an older model from 1995, which is probably why it has this circuit board in place of a convergence menu built into the TV.

If adjusting the convergence still doesn't work, you might need to purchase a new convergence chip.

Some times the picture gets a green and red hue and the menu turns from green to red ,


HI. this is being caused by a faulty convergence chip that is located on the convergence board. simply replacing this chip or replacing the entire board will fix this issue.

Looks like 3D tv


Try doing a calibration. Projection TVs work with 3 picture tubes (Red, Green, Blue). The Red may be off to one side causing the hues.

The manual is available here for instructions on how to perform calibration:

It sound like the control board has a problem. There is two way to fix this.

- Upgrade the firmware of the control board, If you can find the firmware upgrade device.

Toshiba 65H80 has yellow hue.


Check you HD inputs or source. Sounds like the red stream is missing; maybe a loose cable.

Blurred TV - double vision with red hue


I was searching online about what could be the problem with our TV and I came across your page. We have a 52" JVC Projection TV that now has a "blurred" screen. We can see the channels but it looks like it's has a shadow around the images. The screen in in a red hue with green blur.

If you have any suggestions on what caused this and what we can do to have this fixed, I would greatly appreciate your advice.

Picture is yellow and green


Your missing the red drive on the set. Its most likly the picture tube. Its a possibility that the red drive circuit could be not working so the best thing to do is take off the gree picture tube socket and put the green board on the red tube. Of course do all this when the set is unplugged. if you have no tv experience. its not a good idea to be messing around inside of these sets.
