Problem with the Toshiba 50H13 50 in. Rear Projection Television. Green tint


The tubes have aged and the colour balance between the tubes has shifted. You will need to redo it using a black/white test image: first the black (the cutoff point), then the white (the gain) on each tube - always start with the green colour. This is done on the final video amplifier of each tube by adjusting the corresponding semiadjustable resistors.

Red Hue


Go into the service menu and turn down the red push and red cut a few notches. Write down every value in the service menu and be careful to make sure you don't change anything else. Also, turn down the brightness a couple of clicks and the red glow will be gone.

Or, try this - Press Mute on the remote control twice, press Mute a third time and keep holding at the same time, press the Menu button on the TV front panel. If you do it correctly, you will see a small S on the screen. Congrats, you are in service mode. Press Menu on the remote to get to the adjustable settings. Be careful not to change anything without writting the original value down first. Also be careful of hitting other buttons on the remote. To reduce red push, Use the channel up down button until it says RCUT. Adjust the value using the volume button on the remote. I recommend setting RCUT to 80H, which is the preset value according to the service manual. To exit Service Mode, simply power off the TV. Good luck.

It is your projector tub if you are getting alot of blue in the picture. Those guns are very expensive to replace. I am sorry to tell you that. It would be cheaper set from wal-mart for your kids to play on.

Toshiba 65H80 has yellow hue.


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

Image Distorted


This is a classic convergence problem. Please confirm that your model is 51H84 and whether or not you intend to repair this yourself. You will need to know how to solder. If you wish to attempt the repair, confirm the model and update this and I'll provide you with details and instructions.

Problem with color


Yes you have a problem in the red crt driver board. Most likely the driver transistor is failing. This is a component level repair, so if you have no experience with TV repair, play it safe and call in a trained tech to assist you in this matter. Good Luck
